Kentucky Estate Planning Mistakes That Cost Families Money

Most of the costly Kentucky estate cases handled at the firm do not involve sophisticated tax planning or unusual asset structures. They involve ordinary families, ordinary assets, and the same six or seven mistakes repeated again and again. Each of these mistakes is preventable. Each of them shows up in the firm’s probate docket month after month. And each of them quietly costs Kentucky families thousands of dollars, sometimes much more, in legal fees, taxes, lost assets, and family conflict that did not have to happen.

This page walks through the seven most common Kentucky estate-planning mistakes, with the Kentucky Revised Statutes that govern them and a practical sense of what the mistake actually costs. None of this is legal advice for any particular estate — the right plan depends on the facts — but the list is a useful starting point for anyone in Kentucky thinking about whether the current plan is sound.

Mistake 1: Not Having a Will at All

The most common, and the most expensive, estate-planning mistake in Kentucky is having no estate plan at all. When a Kentucky resident dies without a valid will, the estate passes by intestate succession under KRS Chapter 391. The general intestate-succession rules are in KRS 391.010, with the surviving spouse’s dower and curtesy interest in real property in KRS 392.020.

The Kentucky default distribution is often surprising to families. The general structure under KRS 391.010, simplified:

• Surviving spouse and surviving descendants of the decedent: The descendants generally take the personal estate after debts. The realty descends to the descendants subject to the spouse’s dower interest under KRS 392.020 (which is a life estate in one-third of the realty plus an absolute one-half interest in the personalty after debts, in the most common configuration).
• Surviving spouse but no surviving descendants: Personal estate and real estate pass to the spouse and to the decedent’s parents, then to siblings if there are no parents, depending on what survives.
• No surviving spouse, but surviving descendants: Descendants take per stirpes.
• No surviving spouse and no descendants: The estate passes up to parents, then to siblings, then to grandparents, then to aunts, uncles, and their descendants, with escheat to the Commonwealth under KRS 391.020 only if no taker can be identified.

Several common family situations come out badly under the default rules.

Take a married Kentucky couple with two minor children. Without a will, on the death of the first spouse, the children inherit the realty subject to the surviving spouse’s dower interest. The surviving spouse does not own the realty outright. If the surviving spouse wants to sell, refinance, or move, the surviving spouse needs the children’s legal representatives to consent, because minors cannot consent for themselves — that often requires a guardianship and a court-supervised sale of the minor’s interest. None of this is what the spouses generally have in mind.

Take an unmarried Kentucky couple, with or without children together. The intestate succession statute does not recognize an unmarried partner as an heir. The surviving partner inherits nothing under KRS 391.010 unless there is a separate vehicle (joint ownership, beneficiary designation, transfer-on-death, or trust) in place. A non-marital child’s rights are governed by KRS 391.105 and require either acknowledgment or a judicial determination. The lack of a will, in this configuration, can produce a complete disinheritance of the partner.

Take a blended-family situation: one spouse with children from a prior relationship, one spouse with no children, or both spouses with children from prior relationships. Without a will, the dower interest, the children’s shares, and the surviving spouse’s rights interact in ways that frequently produce litigation. The blended-family estate is one of the highest-litigation categories the firm handles, and the litigation is almost always preventable with planning.

The cost of not having a will is rarely felt by the decedent — it is felt by the family. The family pays in legal fees to administer an intestate estate (which is procedurally more complex than a testate estate), in lost flexibility (Kentucky default rules do not adjust for family circumstances), in family conflict (when defaults produce results that do not match anyone’s expectations), and sometimes in lost assets (when contested administration drives down the value of the estate). A Kentucky will drafted by a Kentucky attorney is dramatically cheaper than the litigation that follows when there is no will.

Mistake 2: Using a DIY Will Without Reviewing It with a Kentucky Attorney

The legal requirements for a valid Kentucky will are in KRS 394.040. The statute requires that the will be in writing, signed by the testator (or by another person at the testator’s direction and in the testator’s presence), and either attested by two credible witnesses who subscribe their names in the testator’s presence, or entirely in the testator’s handwriting. Kentucky recognizes holographic wills (entirely handwritten and signed by the testator) under the same statute. A self-proving affidavit under KRS 394.225 is not required for validity but streamlines probate.

The statutory requirements are simple. The drafting is not. The defects the firm sees most often in DIY wills are:

• Improper execution. A common scenario: a testator signs a printed will form in front of a notary but without two attesting witnesses. The notary’s seal does not substitute for the two-witness requirement under KRS 394.040. A will signed only before a notary and without two attesting witnesses is generally not entitled to probate as an attested will. The testator’s plan fails on a technicality the testator did not know existed.
• Witness defects. KRS 394.210 places limits on a witness who is also a beneficiary — the will is not voided, but the gift to the witness-beneficiary may be voided or reduced. A DIY testator who has a beneficiary sign as a witness can disinherit the intended recipient by accident.
• Missing residuary clause. The residuary clause directs what happens to property of the estate not specifically devised. Without one, every asset not specifically named passes by intestate succession under KRS 391.010. A DIY will that names specific assets without a catch-all residuary clause partially dies intestate, with half the estate following the will and half following the default rules.
• Ambiguous bequests. “I leave my house to my children” is ambiguous if the testator owns more than one house. “I leave my truck to John” is ambiguous if the testator owns three vehicles. “I leave my retirement account to my wife” is ineffective because retirement accounts pass by beneficiary designation, not by will. Each ambiguity is a future legal fee.
• Outdated or conflicting beneficiary designations. A will that says “everything to my spouse” cannot override a 401(k) beneficiary designation that names an ex-spouse. Federal ERISA preemption controls qualified retirement plans. The will is overridden by the form on file with the custodian, and the testator’s plan fails.
• “Everything to my spouse” when there are also children. In a blended family, a simple “everything to my spouse” will can disinherit the testator’s children from a prior relationship. The will is valid; the result is not what the testator intended.
• Wrong-state forms. Pre-printed will forms from generic websites sometimes use other states’ execution language, fail to include Kentucky-specific provisions, and use witness procedures that do not satisfy KRS 394.040. A “valid in 50 states” claim on a website is a claim, not a guarantee.
• Pour-over wills with no funded trust. A DIY pour-over will that directs assets to a trust that was never properly executed or never funded creates the worst of both worlds: probate without trust benefits.

The cost of a DIY-will defect is paid at probate. The named executor cannot get the will admitted, or can get it admitted only after litigation. Beneficiaries fight over ambiguous language. Intended gifts go to other people. The estate pays legal fees that are several multiples of what a properly drafted will would have cost. The most painful version is the one where the testator’s actual wishes are clear from context but cannot be carried out because the document does not say what the testator meant. Kentucky probate courts apply the will as written.

The firm’s wills page walks through the components of a Kentucky will package, and the Kentucky wills attorney page covers the drafting process. Both are worth reading before reaching for a generic online form.

Mistake 3: Forgetting Non-Probate Assets

A will only controls probate assets. Many of the most valuable assets in a Kentucky estate are non-probate assets — assets that pass outside of the will, by some other operation of law:

• Retirement accounts (401(k), 403(b), IRA, Roth IRA, SEP-IRA, deferred compensation) pass by the beneficiary designation on file with the plan administrator or custodian. ERISA preempts state law for qualified plans — the will does not control.
• Life insurance proceeds pass to the named beneficiary on the policy. Unless the policy names “my estate” (which is generally a mistake), the proceeds never enter probate.
• Joint tenancy with right of survivorship. Real estate, bank accounts, and brokerage accounts held jointly with right of survivorship pass to the surviving joint owner at the moment of death, outside the will.
• Tenancy by the entirety. Kentucky recognizes tenancy by the entirety in real property held by spouses (and, after a series of statutory amendments, in certain personal property as well). The surviving spouse takes by operation of law.
• Payable-on-death (POD) and transfer-on-death (TOD) designations on bank accounts, brokerage accounts, motor vehicles (KRS 186A.115), and Kentucky real-estate deeds under the Uniform Real Property Transfer on Death Act adopted as KRS 394.310 through 394.370.
• Funded revocable living trust. Assets titled to the trust during the testator’s lifetime pass under the trust’s distribution provisions, not under the will.
• Annuities and certain pension benefits — same rule as retirement accounts: beneficiary designation controls.
• Health savings accounts (HSAs), college savings accounts (529s), and other tax-advantaged accounts — beneficiary designation controls.

The most common, and most expensive, non-probate mistake is leaving an ex-spouse or a deceased relative as a primary beneficiary on a retirement account or life insurance policy. Kentucky has a statute that revokes some testamentary devises on divorce, but it does not cleanly extend to all non-probate transfers, and the federal ERISA preemption framework limits the reach of any state law on qualified plans. In practice, a beneficiary designation that was last updated before a divorce or remarriage is enforced as written.

The fix is mechanical and inexpensive. After every major life event — marriage, divorce, birth of a child, death of a named beneficiary, change of employer, change of investment custodian — pull every beneficiary designation on every retirement account, life insurance policy, annuity, HSA, 529, brokerage TOD, bank POD, and real-estate TOD deed. Confirm primary and contingent beneficiaries. Update where needed. This single exercise resolves a substantial portion of the litigation the firm handles in estate disputes.

It is also worth noting that beneficiary designations interact with KRS Chapter 140 inheritance tax. A life-insurance proceeds payment to a named individual beneficiary is not subject to Kentucky inheritance tax (KRS 140.030 exclusion), but a life-insurance proceeds payment to the estate may be. Coordinating beneficiary designations with the broader plan is a practical part of avoiding accidental tax exposure.

Mistake 4: Not Planning for Incapacity

A will only operates at death. The most common “estate plan” gap is the absence of any document that governs what happens if the principal becomes incapacitated during life. Without incapacity planning, an incapacitated Kentucky adult often requires a court-supervised guardianship under KRS Chapter 387, which is slow, expensive, and public.

The basic incapacity-planning documents are:

• Durable financial power of attorney. Governed by the Kentucky Uniform Power of Attorney Act (UPOAA) at KRS Chapter 386B. The financial POA designates an agent to handle financial matters, with the principal able to specify whether the POA is effective immediately or springing on incapacity, and able to grant or withhold specific powers (including the “hot powers” under KRS 386B.2-010(1) such as making gifts, creating or amending trusts, and changing beneficiary designations, which must be expressly granted in the document).
• Healthcare power of attorney / living will / advance directive. Kentucky’s “Kentucky Living Will Directive Act” is at KRS 311.621 through 311.643. The healthcare power of attorney lets the principal designate an agent to make medical decisions if the principal cannot do so, and the living-will provisions let the principal direct end-of-life treatment preferences.
• HIPAA authorization. A standalone HIPAA-compliant authorization gives the designated agent and family members access to medical information that providers would otherwise be statutorily prohibited from disclosing under the federal Health Insurance Portability and Accountability Act.
• Mental health declaration. Under KRS 202A.420 through KRS 202A.432, a principal can create a declaration concerning psychiatric treatment, identifying a designated agent and preferred treatment.

Without these documents in place, the family of an incapacitated person typically has to file a petition for guardianship and conservatorship in District Court. The proceeding is governed by KRS Chapter 387, requires a clinical evaluation under KRS 387.540, can require a jury trial under KRS 387.580, and routinely takes several months and several thousand dollars in fees to complete. The court appoints a guardian and a conservator (which may or may not be the family member the principal would have chosen), and the appointed fiduciary is subject to ongoing court reporting and supervision.

Compare that to a properly drafted incapacity package: an agent who can step in immediately on incapacity, a healthcare agent who can make medical decisions without litigation, a HIPAA authorization that gets the family access to medical information without delay, and no court involvement at all unless the principal’s situation requires it. The cost of preparing a complete incapacity package is a fraction of the cost of a guardianship.

Mistake 5: Naming the Wrong Executor or Trustee

The choice of executor (and, where there is a trust, of trustee) is one of the most important practical decisions in any Kentucky estate plan. The wrong choice produces administration delays, family conflict, litigation, and unnecessary cost.

The Kentucky-specific considerations:

• Bond. Under KRS 395.130, a personal representative must give bond unless the will expressly waives bond. A properly drafted will usually waives bond, which saves the estate the cost of a surety. A DIY will or an outdated will may not include a bond-waiver clause, and the estate pays the bond premium as a result.
• Non-resident executor. KRS 395.005 imposes specific requirements when the named personal representative is a non-resident of Kentucky, including the appointment of a process agent. A non-resident executor is allowed but is procedurally heavier. Naming an in-state co-executor or a local successor can streamline administration.
• Successor language. A common defect is naming a single executor without naming a successor. When the named executor predeceases the testator, declines to serve, or is unable to serve, the estate has to go through the process under KRS 395.150 of having the court name an administrator with the will annexed. Naming first and second alternate executors in the will avoids that step entirely.
• Family-member executor vs. corporate or professional fiduciary. A family-member executor saves the estate the corporate-trustee fee but takes on responsibility for managing the administration. A corporate trustee (such as a bank trust department) is more expensive but provides continuity and is less likely to generate family conflict over distribution decisions. The right choice depends on the family.
• Co-executors and co-trustees. Naming co-executors (two siblings together, for example) can work if the named individuals can cooperate. It can also produce administrative deadlock if the co-executors disagree about routine decisions. The will should specify whether co-executors must act jointly or may act severally.
• Trustee tenure and removal. If the estate plan includes a long-term trust (for minor beneficiaries, for special-needs beneficiaries, for a spousal trust), the document should include provisions for trustee removal by the beneficiary or by a trust protector, so that a poorly performing trustee can be replaced without litigation.

The wrong executor can drag a Kentucky probate from the six-to-nine-month typical timeline out to two or three years. The wrong trustee can produce decades of conflict. The choice is worth thinking carefully about, and the right answer often is not the eldest child or the closest sibling — it is the family member or professional who is most likely to administer the trust impartially, follow the document, and communicate clearly with beneficiaries.

Mistake 6: Ignoring Kentucky Inheritance Tax

Kentucky is one of a small number of states that imposes an inheritance tax. The tax is governed by KRS Chapter 140 and is imposed on the beneficiary’s receipt of property based on the beneficiary’s relationship to the decedent. Kentucky does not impose a separate state estate tax. The federal estate tax exemption is high enough that most Kentucky estates owe no federal estate tax. But the Kentucky inheritance tax is a different matter, and it surprises Kentucky families regularly.

The structure under KRS Chapter 140:

• Class A beneficiaries — surviving spouse, parent, child (including adopted child and stepchild), grandchild, brother, sister (including half-brothers and half-sisters of the whole blood), and certain others under KRS 140.080 — are exempt from Kentucky inheritance tax.
• Class B beneficiaries — nephew, niece, half-brother or half-sister of the half-blood, daughter-in-law, son-in-law, aunt, uncle, and great-grandchildren in certain configurations — receive a $1,000 exemption and are then taxed on a progressive schedule from 4% to 16%.
• Class C beneficiaries — all other beneficiaries, including unrelated friends, charities other than those qualifying for KRS 140.060 exemption, and more distant relatives — receive a $500 exemption and are then taxed on a progressive schedule from 6% to 16%.

Note that certain charitable, educational, religious, and governmental beneficiaries are exempt under KRS 140.060, and qualified retirement-plan distributions and life-insurance proceeds payable to a named individual are treated specially under KRS 140.030. The rates above are the basic structure; the application is fact-specific.

Two common Kentucky scenarios produce avoidable inheritance-tax exposure.

The first is the unmarried Kentucky resident with no children who leaves an estate to a longtime partner, a friend, or a niece or nephew. The Class B or Class C tax on a $500,000 net estate can run into the tens of thousands of dollars. With planning, that exposure is reducible — through lifetime gifting under federal annual-exclusion limits, through charitable structuring, through use of qualifying retirement-account distributions, and in some configurations through trust planning.

The second is the small-business owner who leaves a closely held business to a non-Class-A beneficiary (a nephew who has been working in the business, for example). The valuation of the business interest at death drives the tax, and the tax is due even if the beneficiary cannot easily liquidate the interest to pay. The result, every few years, is a Kentucky inheritance-tax bill that forces a sale or a debt-financed payment of tax. The right planning vehicle, set up well before death, can change that outcome.

The takeaway is not that every Kentucky estate needs sophisticated tax planning. Most do not. The takeaway is that estates leaving substantial assets to anyone other than Class A beneficiaries should look at the inheritance-tax exposure as part of the plan, rather than discovering the bill at the probate court’s settlement stage.

Mistake 7: Setting It and Forgetting It

An estate plan is not a one-time event. It is a document set that should be reviewed every three to five years and updated on every major life event. The plan drafted at age forty for a married couple with young children is rarely the right plan at age sixty with adult children and grandchildren, and almost never the right plan at age seventy-five with retirement accounts, healthcare considerations, and possibly a second marriage.

Events that should trigger an estate-plan review:

• Marriage. Both spouses’ wills, beneficiary designations, joint-titling, and tax considerations all change.
• Divorce. Kentucky has a statute that revokes certain testamentary devises to a former spouse on divorce (KRS 394.092), and federal ERISA preemption complicates beneficiary designations on qualified plans. Every document needs review.
• Birth or adoption of a child or grandchild. Specific bequests, residuary provisions, contingent trusts for minors, and guardian-of-the-person designations under KRS 387.040 all need review.
• Death of a named beneficiary or executor. If the primary executor or a residual beneficiary has died, the plan needs to be updated.
• Significant change in assets. A substantial inheritance, business sale, real-estate acquisition or sale, or change in retirement-account balance may change the underlying tax and distribution analysis.
• Move to or from Kentucky. A will valid in another state is generally valid in Kentucky under KRS 394.090 if executed in compliance with that state’s law, but state-specific provisions (Kentucky inheritance tax, dower, intestate-share rules) may produce different outcomes. A move requires a fresh look.
• Federal estate-tax law change. The federal estate-tax exemption is scheduled to revert to a lower level after December 31, 2025 absent further legislative action. Estates that were below the exemption when the plan was drafted may be over it under the post-reversion exemption. Plans drafted before 2017 may not reflect the current framework at all.
• Major change in family relationships. Estrangement from a beneficiary, blending of families through remarriage, the disability of a beneficiary that calls for special-needs planning, or a beneficiary’s creditor or marital issues that call for protective planning.
• Move of a named fiduciary out of state, illness of a named fiduciary, or change of circumstances of a named fiduciary. The executor or trustee who was the right choice ten years ago may no longer be available or appropriate.

An estate plan should be a living document. The firm’s practice is to suggest a check-in every three to five years on average, with adjustments on a triggering event. The cost of a periodic update is small. The cost of administering an estate under a twenty-year-old plan that does not reflect the family or the law as they currently stand is not.

Kentucky Estate Planning FAQ

What happens if I die without a will in Kentucky?

Kentucky’s intestate succession statute, KRS 391.010, decides who inherits. If there is a surviving spouse and surviving descendants, the descendants take the bulk of the personal estate and the descendants share the realty subject to the spouse’s dower interest under KRS 392.020. If there are no descendants, the estate generally passes to parents, then siblings, then more distant relatives, with escheat under KRS 391.020 only as a last resort. The state’s default distribution is often not what people expect.

Do I need a lawyer to make a will in Kentucky?

Kentucky does not require an attorney to draft a will. KRS 394.040 sets the execution requirements, and a will signed and witnessed in accordance with the statute is valid even without counsel. That said, the will-contest, ambiguity, and probate-litigation cases the firm sees every year almost all start with a DIY will. The cost of legal drafting is small compared to the cost of litigating a defect after the testator’s death.

How much does a Kentucky will cost?

Costs depend on complexity. A simple Kentucky will typically falls in the $300 to $750 range. A coordinated package including a will, durable financial power of attorney, healthcare power of attorney, living will / advance directive, and HIPAA authorization typically falls in the $750 to $1,800 range. Cases involving trusts, blended families, business interests, or larger estates require additional time and are quoted on the facts.

Is a handwritten will valid in Kentucky?

Kentucky recognizes holographic wills under KRS 394.040, but only if the will is wholly in the testator’s own handwriting and signed by the testator. A typed will with handwritten edits is generally not a valid holographic will. A holographic will that meets the statutory standard is admissible to probate but generates disproportionate litigation over interpretation. It is not a recommended primary planning vehicle.

Does Kentucky have an estate tax?

No. Kentucky does not impose a state estate tax. The federal estate tax applies, but the federal exemption (currently $13.61 million per individual for 2024, scheduled to revert to a lower level after December 31, 2025 absent further legislation) is high enough that most Kentucky estates owe no federal estate tax. Kentucky does, however, impose an inheritance tax under KRS Chapter 140 on certain beneficiaries.

What is Kentucky inheritance tax?

Kentucky inheritance tax is governed by KRS Chapter 140. The tax is imposed on the recipient based on the beneficiary’s relationship to the decedent. Class A beneficiaries (spouse, parent, child, grandchild, brother, sister, and certain others) are exempt under KRS 140.080. Class B (nieces, nephews, aunts, uncles, and certain others) and Class C (all other beneficiaries) are taxed on a progressive schedule, with Class C topping out at 16%. Leaving substantial assets to Class B or Class C beneficiaries without planning is one of the most common avoidable mistakes.

How often should I update my will in Kentucky?

The standard guidance is review every three to five years, with a fresh look on any of these events: marriage, divorce, birth or adoption of a child, death of a named beneficiary or executor, a substantial change in assets, a move to or from Kentucky, a significant change in federal estate-tax law, a change in business ownership, or a major change in family relationships. An out-of-date will creates the same problems as no will at all.

Do I need a trust if I have a will?

Not necessarily. A trust is a planning tool, not a default. Trusts are useful for probate avoidance, for management of assets across multiple generations, for protection of assets from creditors of beneficiaries, for special-needs planning, and for blended families. A simple Kentucky estate with most assets passing through beneficiary designations or joint ownership may not need a trust at all. The right question is whether a particular planning goal calls for a trust, not whether trusts are universally required.

What is a transfer-on-death designation?

A transfer-on-death (TOD) or payable-on-death (POD) designation lets an asset pass directly to a named beneficiary at death, outside of probate. Kentucky recognizes TOD designations on motor-vehicle titles under KRS 186A.115, on real-estate deeds under the Uniform Real Property Transfer on Death Act adopted as KRS 394.310 through 394.370, and on most financial accounts. TOD planning is a clean and inexpensive probate-avoidance tool when used carefully.

What happens to my retirement account when I die?

Retirement accounts (401(k), 403(b), IRA, and similar) pass according to the beneficiary designation on file with the plan administrator or custodian, not according to the will. Federal ERISA preemption controls qualified plans, and the named beneficiary takes regardless of contrary language in a will. The most common mistake is leaving an ex-spouse or a deceased relative on the designation. Reviewing beneficiary designations is the highest-leverage estate-planning task that does not require drafting any new document.

Can I write my own will in Kentucky?

Yes. KRS 394.040 sets the execution requirements: a will must be in writing, signed by the testator (or by another at the testator’s direction and in the testator’s presence), and either attested by two credible witnesses subscribing in the testator’s presence, or entirely in the testator’s handwriting. The validity of a self-drafted will is not the issue. The issue is whether the will the testator drafted accomplishes the testator’s actual goals without creating ambiguity, contradiction, or unintended disinheritance.

Do I need to file my will with the court before I die?

No. Kentucky does not require filing a will during the testator’s lifetime. The will is admitted to probate after death, typically by the named executor filing a petition with the District Court. Kentucky does, however, permit a testator to deposit a will with the District Clerk for safekeeping under KRS 394.270, which is a practical option for testators who want to ensure the original document is preserved and findable.

What is a residuary clause and why do I need one?

A residuary clause directs what happens to property of the estate not specifically given by the will. Without a residuary clause, any property not specifically devised passes by intestate succession under KRS 391.010 — meaning part of the estate is governed by the will and part by state default rules, which is almost never what the testator intended. A missing residuary clause is one of the most common defects in DIY wills.
