Estate Planning in Kansas

Kansas estate planning demands attention to two rules that catch families off guard: a will is entirely revoked when the testator marries and has a child, and the elective share reaches into nonprobate assets on a marriage-length sliding scale from 3% to 50%. Add in a will preparer rule that voids gifts to the drafter, no holographic wills, and the rare recognition of oral wills — and Kansas emerges as a state where the details matter more than most.

What most people don't know about Kansas

In Kansas, if you make a will and then marry AND have or adopt a child, your entire will is automatically revoked — not just amended to include the new child. The estate is distributed under intestacy law as if you never made a will at all. Most states simply give an after-born child an intestacy share while keeping the rest of the will intact. Kansas wipes the slate clean when marriage and a child come together after the will was made. For anyone who wrote a will before getting married and starting a family, the will they think protects them may no longer exist.

Source: K.S.A. § 59-610

Plain English Rules

  • Making a will then marrying and having a child revokes the ENTIRE will — Kansas treats you as if you died without a will; most states just add the child's share
  • The elective share is based on marriage length — a sliding scale from 3% (under 1 year) to 50% (15+ years) of the augmented estate, with a $100,000 supplemental minimum
  • A will requires two witnesses who sign in the testator's presence — holographic (handwritten, unwitnessed) wills are NOT valid in Kansas
  • Oral wills are recognized for personal property during 'last sickness' — but must be reduced to writing and subscribed by two witnesses within 30 days
  • Kansas has no state estate tax or inheritance tax — only the federal estate tax applies to very large estates
  • A gift in a will to the person who prepared the will is automatically invalid unless the preparer is a relative or the testator had independent legal advice

What Actually Breaks

Will made before marriage and children

Entire will is revoked when testator marries AND has a child — estate distributes under intestacy as if no will exists

Will prepared by a non-relative who is also a beneficiary

The gift to the preparer is automatically void — unless the testator had independent legal advice about the provision

Holographic will (handwritten, no witnesses)

Invalid — Kansas does not recognize holographic wills; the document has no legal effect regardless of how clear the testator's intent

Short marriage with spouse left out of will

Spouse can still elect against the will — even after just 1 year of marriage, the elective share is 6% of the augmented estate (or the $100,000 supplemental minimum, whichever is greater)

Beneficiary serves as one of only two witnesses

The beneficiary-witness's gift is voided unless two additional disinterested witnesses signed — exception: heir can receive up to their intestacy share

Creditors not notified within required period

Known creditors who are not given proper notice may have extended claim periods — proper publication and mailing are essential

No advance directive before incapacity

Medical decisions fall to a statutory surrogate hierarchy; without a healthcare agent designation, family members may need to seek guardianship

If This Is Your Situation

Married with no children (intestacy)

Surviving spouse inherits the entire estate

Married with children (intestacy)

Surviving spouse receives one-half of the estate; children share the other half equally

Will made before marriage and birth of child

Will is entirely revoked — estate distributes under intestacy law as if no will existed

Spouse left out of will (married 15+ years)

Spouse can elect against the will and claim 50% of the augmented estate (includes nonprobate transfers) or the $100,000 supplemental minimum, plus homestead allowance

Estate under $75,000

Small estate affidavit available — heir prepares a short affidavit and presents it to asset holders with a death certificate

Oral statement of wishes during last illness

Can be valid as a nuncupative will for personal property IF two competent disinterested witnesses heard it, the testator called them to bear witness, and it's reduced to writing within 30 days

Want to avoid probate for real estate

Transfer-on-death deed available in Kansas — transfers real property directly to a beneficiary at death without probate; revocable during lifetime

How Kansas Actually Works

Kansas has not adopted the Uniform Probate Code but has selectively adopted the UPC's augmented estate elective share framework — arguably the most sophisticated spousal protection system in the country.

The most consequential rule for families is the will revocation by marriage and child. Under K.S.A. § 59-610, if you make a will and then marry AND have or adopt a child, the entire will is automatically revoked. Not amended, not adjusted — revoked. Your estate distributes under intestacy law as if you never made a will. Most states handle this by giving the after-born child an intestacy share while keeping the rest of the will intact. Kansas eliminates the whole document. This means anyone who wrote a will before getting married and starting a family needs to make a new one.

Kansas's elective share system uses a marriage-length sliding scale applied to the augmented estate — which includes not just probate assets but also nonprobate transfers like trusts, life insurance, retirement accounts, and joint accounts. The percentage ranges from 3% for marriages under one year to 50% for marriages of 15 years or more. There is also a $100,000 supplemental minimum: if the combined amounts from the formula don't reach $100,000, the spouse gets the difference. This means even a short marriage provides substantial protection, and a long marriage gives the surviving spouse a claim to half of everything.

Kansas does not recognize holographic wills — a handwritten will without witnesses is invalid. But Kansas does recognize nuncupative (oral) wills for personal property during the testator's last sickness, provided two competent disinterested witnesses heard it and the statement is reduced to writing within 30 days. Kansas also has a unique will preparer rule: any gift to the person who prepared the will (or a close relative) is automatically void unless the preparer is related to the testator and the gift doesn't exceed the intestacy share, or the testator had independent legal advice. This is one of the strongest anti-undue-influence protections in the country.

Without a Will: How Kansas Distributes Your Estate

Kansas follows common law property rules. When someone dies without a will, state intestacy law determines who inherits — and the result depends on your family structure.

Kansas intestacy is straightforward compared to the state's complex elective share system. If married with no children, the spouse inherits everything. If married with children, the spouse receives one-half and the children share the other half equally.

The 120-hour survivorship period requires heirs to outlive the decedent by five days. Advancements — property given to an heir during the decedent's lifetime — are subtracted from that heir's intestacy share. And uniquely, Kansas allows children who were placed for adoption by the decedent to inherit from their natural parent, even after being legally adopted by another family.

Married with children (same marriage)

Surviving spouse receives one-half of the estate. Children share the other half equally.

Married with children from a prior relationship

Same rule — surviving spouse receives one-half; all children (regardless of parentage) share the other half equally.

Married, no children

Surviving spouse inherits the entire estate.

Single with children

Children inherit the entire estate equally. If a child predeceased the decedent, that child's descendants inherit by representation.

Single, no children

Parents inherit equally. If no parents survive, siblings inherit. The chain continues through increasingly distant relatives. Children placed for adoption can still inherit from natural parents in Kansas.

Survival period: 120 hours (5 days)

Kansas intestacy is straightforward compared to its elective share system. The spouse always gets at least half (or all if no children). Advancements are recognized — property given to an heir during the decedent's lifetime is subtracted from that heir's intestacy share. Half-blood relatives inherit equally with whole-blood. Adopted children who were placed for adoption by the decedent can still inherit from their natural parent — unusual among states.

Wills in Kansas

What makes a will valid

A written will signed at the end by the testator and attested by two or more competent witnesses who saw the testator subscribe or heard the testator acknowledge the will. Must be on paper — no electronic wills. Holographic wills are not recognized.

What people think

That a handwritten will is valid as long as it's clear, or that a will made before marriage and children remains in effect.

What actually happens

Kansas does not recognize holographic wills — a handwritten will without witnesses is invalid. More importantly, if you marry AND have a child after making a will, the entire will is revoked. This catches people off guard because most states just give the new family member an intestacy share. Kansas eliminates the whole document. Divorce, by contrast, only revokes provisions for the former spouse — the rest of the will stays intact.

Common failure

Wills made before marriage and children that are entirely revoked by the combination. Also: holographic wills (no witnesses), gifts to will preparers (automatically void), and using beneficiaries as the only witnesses.

When a trust is better

When you want to avoid probate, when managing distributions to minors, when privacy matters, or when you want to control how assets are distributed after a second marriage. Note: trust assets are included in the augmented estate for elective share calculations.

Execution checklist

  1. Ensure the testator is 18+ and of sound mind
  2. Put the will in writing on paper — electronic and holographic wills are not valid
  3. Sign the will AT THE END of the instrument
  4. Have two or more competent witnesses sign in the testator's presence
  5. Use disinterested witnesses to avoid the interested-witness rule
  6. Do NOT have the will prepared by someone who is also a beneficiary
  7. Execute a self-proving affidavit (notarized) — strongly recommended
  8. Include provisions for future children to prevent will revocation by marriage + child
  9. Store the original securely

Power of Attorney in Kansas

What it does

Grants authority to a named agent to manage financial and legal affairs on behalf of the principal. Healthcare decisions require a separate advance directive.

Key rule

Kansas follows the Kansas Power of Attorney Act. The POA must include specific durability language to survive incapacity.

Real-world friction

Financial institutions may have their own POA forms. Using the Kansas statutory form reduces rejection risk.

Common mistake

Assuming a financial POA covers healthcare decisions. Kansas separates these authorities — you need both a durable financial POA and an advance directive for healthcare.

See Kansas document signing requirements →

Healthcare Directive in Kansas

What it covers

Your preferences for life-sustaining treatment and the designation of a healthcare agent to make medical decisions during incapacity.

What's different

Kansas provides a statutory form for the advance directive. The state recognizes both living wills and durable healthcare POAs.

Execution requirements

Two witnesses or notarization required. The healthcare agent and employees of the treating facility should not serve as witnesses.

Common misunderstanding

Confusing a financial POA with a healthcare advance directive. They are separate documents. Without an advance directive, medical decisions fall to a statutory surrogate hierarchy.

See Kansas document signing requirements →

Probate in Kansas

When required

When assets are held solely in the decedent's name without a beneficiary designation, TOD deed, joint ownership, or trust — and the estate exceeds $75,000.

What makes Kansas different

Kansas has not adopted the Uniform Probate Code but has adopted the UPC's augmented estate elective share framework. The elective share uses a marriage-length sliding scale (3% to 50%) with a $100,000 supplemental minimum — making it one of the most comprehensive spousal protection systems in the country. The will revocation by marriage + child is far more drastic than most states. Kansas allows both oral wills (for personal property during last sickness) and transfer-on-death deeds for real property.

Probate paths

Small estate affidavit· Weeks

For estates with probatable assets of $75,000 or less. Heir prepares affidavit and presents it to asset holders with a death certificate.

Simplified probate· 3–6 months

For straightforward estates above $75,000. Personal representative files a request for streamlined administration.

Standard administration· 6–12 months

Full court-supervised process for larger or contested estates.

What people get wrong

Assuming that a will made before marriage and children is still valid. In Kansas, the combination of marriage AND a child revokes the will entirely. Also: not understanding that the elective share reaches into nonprobate transfers (the augmented estate), which means trusts, life insurance, and retirement accounts are all included in the calculation.

Trusts in Kansas

When a trust is useful

Avoiding probate, managing distributions to minors, maintaining privacy, or planning around the elective share (though trust assets are included in the augmented estate calculation). Transfer-on-death deeds are a simpler alternative for real estate.

When a trust is unnecessary

Estates under $75,000 (which can use the small estate affidavit), or simple estates that can be managed with TOD deeds, beneficiary designations, and joint ownership.

Key mistake

Assuming a trust protects against the surviving spouse's elective share. Kansas adopted the augmented estate approach — trust assets are included in the elective share calculation. The trust avoids probate but does NOT defeat the spouse's claim to the elective-share percentage.

Common Mistakes

Not updating a will after marriage and birth of a child

Kansas revokes the ENTIRE will if the testator marries AND has or adopts a child after making it. Most states just give the new child an intestacy share. Kansas eliminates the whole document.

Creating a holographic will

Kansas does not recognize holographic wills. A handwritten will without two witnesses is completely invalid, regardless of how clearly it states the testator's wishes.

Having the will prepared by a beneficiary

Kansas automatically voids any gift to the person who prepared the will (or a close relative of the preparer) unless the preparer is related to the testator and the gift doesn't exceed the intestacy share, OR the testator had independent legal advice.

Assuming a trust defeats the elective share

Kansas uses the augmented estate approach for the elective share — trust assets, life insurance, retirement accounts, and other nonprobate transfers are all included in the calculation. A trust avoids probate but does NOT reduce the spouse's claim.

Not knowing the elective share sliding scale

Kansas's elective share ranges from 3% (under 1 year of marriage) to 50% (15+ years) of the augmented estate. There's also a $100,000 supplemental minimum. A long-married spouse who is disinherited can claim up to half of everything, including nonprobate assets.

Using beneficiaries as witnesses

Gifts to interested witnesses are voided unless two additional disinterested witnesses also signed. The exception: an heir-witness can receive up to their intestacy share.

Not using a TOD deed for real property

Kansas allows transfer-on-death deeds that pass real property directly to a named beneficiary at death without probate. A simple, revocable tool that many families don't know about.

What Most People Actually Need

Most people don't need a trust. They need a valid will, a durable power of attorney, and a healthcare directive — executed correctly under Kansas law. The most common mistakes are ones of execution, not planning.

Frequently Asked Questions

Does Kansas have an estate tax or inheritance tax?

No. Kansas does not impose a state estate tax or inheritance tax. Only the federal estate tax applies, which currently affects estates exceeding $15 million (2026 threshold).

What happens to a will when you get married and have a child in Kansas?

If you make a will and then marry AND have or adopt a child, the entire will is automatically revoked. Your estate is distributed under intestacy law as if you never made a will. This is far more drastic than most states, which typically just add the new child's share. The revocation requires BOTH marriage AND a child — marriage alone or a child alone does not revoke the will.

Are holographic (handwritten) wills valid in Kansas?

No. Kansas does not recognize holographic wills. A handwritten will without two witnesses is invalid. However, Kansas does recognize nuncupative (oral) wills for personal property during the testator's last sickness — one of the few states to do so.

How does Kansas's elective share work?

Kansas uses a marriage-length sliding scale from 3% (under 1 year) to 50% (15+ years) applied to the augmented estate — which includes nonprobate transfers like trusts, life insurance, and retirement accounts. There's also a $100,000 supplemental minimum. The elective share and homestead allowance are separate and cumulative.

What happens if you die without a will in Kansas?

If you leave a spouse and no children, the spouse inherits everything. If you have children, the spouse receives one-half and the children share the other half equally. If no spouse, children inherit everything. The 120-hour survivorship requirement applies.

What is Kansas's small estate threshold?

Kansas allows a small estate affidavit for estates with probatable assets of $75,000 or less. The heir prepares a short affidavit and presents it to banks and other asset holders with a death certificate. No court filing required.

Can the person who prepared my will also be a beneficiary?

Generally no. Kansas automatically voids any gift to the person who prepared the will (or a close relative) unless the preparer is related to the testator and the gift doesn't exceed what they would receive under intestacy, OR the testator had independent legal advice. This protects against undue influence.

Does Kansas allow transfer-on-death deeds?

Yes. Kansas allows TOD deeds for real property, which transfer directly to a named beneficiary at death without probate. The deed is revocable during the owner's lifetime.
