Do I Need a Will or a Living Trust?
By Joshua Harden, Attorney | Memento Mori Law
If you are beginning to plan for the future, one of the first questions you may have is whether you need a will, a living trust, or both. These documents serve different purposes, and the right choice depends on your family, your property, and what you want to happen if you become incapacitated or die.
Key Points at a Glance
A will directs the distribution of probate assets and can nominate a guardian for minor children.
A properly funded living trust may help manage trust property during incapacity and avoid probate for trust assets.
Creating a trust does not automatically transfer property into it.
The right approach depends on family circumstances, asset ownership, and goals.
What Does a Will Do?
A will identifies who should receive property that passes through your estate, can nominate a guardian for minor children, and names a person to administer the estate. It can be an important foundation for an estate plan.
A common misunderstanding is that a will avoids probate. It does not. If assets need to pass under a will, a probate proceeding may still be necessary. Some assets pass outside probate through beneficiary designations, survivorship ownership, or other arrangements.
What Is a Revocable Living Trust?
A revocable living trust is a legal arrangement in which a trustee holds and manages assets under instructions you establish. Many people serve as their own trustee while they are alive and capable. A successor trustee can step in when needed.
A properly funded trust can often allow the assets it owns to be managed and distributed after death without probate for those assets. It can also provide a framework for managing trust property during incapacity.
The phrase 'properly funded' matters. Creating a trust document does not automatically move a home, bank account, or other asset into the trust. Titles and beneficiary arrangements need to be coordinated with the plan.
When Might a Will Be Enough?
A will-centered plan may be appropriate when your circumstances are straightforward and your assets can be handled through a combination of a will, beneficiary designations, and other planning tools. Whether probate would be required depends on the assets and applicable law.
When Might a Living Trust Be Worth Considering?
A trust may be particularly useful if you own real estate, want to provide for beneficiaries over time, have a blended family, own property in more than one state, or want detailed instructions for management if you cannot handle financial affairs yourself.
A living trust is not a universal tax shelter, does not automatically protect your own assets from creditors, and does not replace every other estate planning document.
Do I Still Need a Will If I Have a Trust?
Often, yes. Many trust-based plans include a 'pour-over will' to address assets left outside the trust and to nominate guardians where appropriate. A pour-over will does not necessarily avoid probate for assets that remain in your individual name.
What About Powers of Attorney and Health Care Decisions?
An estate plan should also consider who can make financial and medical decisions if you become unable to do so. Powers of attorney and health care directives address important issues that a will alone does not solve. The documents and signing requirements differ by state.
How Do I Choose?
Start by listing your major assets, how they are titled, who you want to benefit, and any concerns about minor children, incapacity, or family conflict. Then consider whether your plan will actually work with existing deeds, account titles, and beneficiary designations.

What a Will Actually Does
A will directs the distribution of property that becomes part of your probate estate and can nominate a personal representative and, in appropriate circumstances, a guardian for minor children. It is a fundamental document, but it does not automatically transfer every asset and does not, by itself, eliminate probate.
Suppose you leave everything equally to your children in a will but name one child as beneficiary of an investment account. The account's beneficiary designation may control that asset, even though the will describes a different overall division. That is why a will should be reviewed alongside account titles and beneficiary forms.
How a Living Trust Works
A revocable living trust is an arrangement for holding and managing property under written instructions. You may serve as trustee during life and name a successor trustee to step in under defined circumstances. The trust can direct distributions after death and may help avoid probate for assets properly transferred to it.
A trust is not self-funding. A home still titled in your individual name or an account never coordinated with the trust may not pass as expected. Trust administration also involves duties, records, expenses, and sometimes tax or creditor issues. Avoiding probate does not mean avoiding all administration.
Comparing the Practical Tradeoffs
A will-based plan may be simpler to establish and appropriate for some families, particularly when assets already pass through valid beneficiary or survivorship arrangements. A trust-based plan may be useful for multiple properties, privacy concerns, management during incapacity, or more detailed instructions for beneficiaries.
The cost of a trust includes not just preparing the document but coordinating deeds, accounts, and ongoing changes. Conversely, a simpler plan that leaves substantial property to probate can create administrative work for the family. Neither option is universally best.
Special Circumstances That Change the Analysis
Blended families, children with disabilities, beneficiaries who struggle with money, business interests, and property in more than one state may call for tailored provisions. The plan should address not only who receives an asset but also when, under whose management, and with what protections.
A married couple should also consider each spouse's rights, existing jointly owned property, and what happens after the first death. Kansas and Missouri have different legal frameworks; a plan should be prepared for the circumstances rather than copied from a generic checklist.
Documents That Work Alongside Either Choice
A complete estate plan often includes financial powers of attorney, health care directives, beneficiary reviews, and instructions for where records can be found. A pour-over will may be used with a trust, but property passing through that will may still require probate.
Before choosing, make an inventory of assets and ownership, identify the people you trust to act, and write down your goals. Joshua Harden can then help assess which combination of documents fits your Kansas or Missouri household.
Kansas and Missouri: Legal Rules and Sources
Trust Powers and Trustee Duties
Kansas: K.S.A. 58a-602 governs revocation and amendment of revocable trusts, including rules about the trust’s specified method, evidence of intent, and authority of an agent or conservator. K.S.A. 58a-813 establishes trustee duties to inform and report, subject to trust terms and statutory exceptions. In many cases a trustee must notify qualified beneficiaries within 60 days after accepting the trusteeship or learning that a trust has become irrevocable.
Missouri: RSMo 456.6-602 governs amendment and revocation of revocable trusts. The precise method depends on the trust terms, statutory conditions, the settlor’s capacity, and any applicable authority of an agent or conservator. RSMo 456.8-813 requires beneficiary information and reports subject to its qualifications. Importantly, the current Missouri provision generally uses 120 days for the specified acceptance and irrevocability notices, not the older 60-day version. These are different from the duties of a court-appointed executor.
Inheritance Without a Will
Kansas: K.S.A. 59-504 gives the surviving spouse the entire intestate estate if there are no surviving children or descendants of deceased children. If there are surviving children or such descendants, the spouse generally takes one-half, and the descendants take the remaining portion under the succession rules. The rule concerns intestate property, not every jointly owned or beneficiary-designated asset.
Missouri: RSMo 474.010 uses a different formula. A surviving spouse generally takes the entire intestate estate if the decedent has no surviving descendants; the first $20,000 plus one-half the balance when all surviving descendants are also descendants of the surviving spouse; or one-half when at least one surviving descendant is not a descendant of the spouse. Other family and property facts can change the analysis.

Missouri Electronic Wills and Estate Documents: 2025 Law
Missouri enacted the Uniform Electronic Wills Act effective August 28, 2025 (RSMo 474.540–474.564). Section 474.548 recognizes electronic wills executed with the specified testator signature and two witness signatures in physical or electronic presence. This does not make every emailed, typed, scanned, or electronically signed document a valid will. The statutory definitions, execution formalities, custody and certified-copy rules, and the specific document must be evaluated.
Separately, RSMo 474.560 authorizes electronic execution of qualifying estate planning documents such as powers of attorney, trusts, beneficiary deeds, and health care directives, subject to other applicable legal requirements. Section 474.560 does not replace the special electronic-will rules. Kansas execution and recording requirements are separate and should not be assumed identical.
Missouri Electronic Trust Documents
Missouri RSMo 474.560 expressly includes revocable trusts, amendments, modifications, revocations, and irrevocable trusts among the estate-planning documents eligible for electronic execution under that statute. Whether a particular document was validly executed, and whether it changes a beneficiary’s rights or transfers ownership of an asset, remains a separate legal question. The rule does not mean that electronically signing a trust automatically funds it. Kansas trust and execution rules are distinct.
Trustee Notice Exceptions and Older Missouri Trusts
Missouri RSMo 456.8-813 generally requires a trustee to notify qualified beneficiaries within 120 days after accepting the trusteeship and within 120 days after learning that a formerly revocable trust became irrevocable, subject to the statute and applicable trust terms. The section also provides for annual reports to specified beneficiaries, with the possibility of waiver.
An important exception appears in subsection 8: RSMo 456.8-813 does not apply to a trust created under an instrument that became irrevocable before January 1, 2005. Earlier law continues to govern those trusts. Kansas K.S.A. 58a-813 contains different notice provisions, generally including 60-day periods, with statutory and trust-term qualifications. Families should determine which state’s law governs the trust before applying either timeline.
Missouri Electronic Wills: 2025 Law and Witness Requirements
Missouri enacted a separate electronic-wills framework effective for wills of decedents who die on or after August 28, 2025. RSMo 474.548 permits a qualifying electronic will to be signed by the testator (or another individual at the testator’s direction and in the testator’s physical presence) and signed by at least two witnesses in the testator’s physical or electronic presence, subject to the statute. RSMo 474.540 through 474.564 contain additional definitions, requirements, and rules for electronic wills. The separate RSMo 474.560 rule authorizing electronic witnessing of other estate-planning documents excludes wills from that particular provision, but does not prohibit electronic wills under RSMo 474.548. A video call or electronic signature alone does not guarantee a valid will; the complete electronic-wills framework must be satisfied. Kansas will execution and electronic-record requirements must be considered separately.
Electronic-Will Witnesses and Cross-State Execution
Missouri RSMo 474.548(3) adds a witness-location requirement when an electronic will is not accompanied by a contemporaneously signed self-proving affidavit: a witness must be a resident of a state and physically located in a state when signing. RSMo 474.550 separately provides rules for making an electronic will self-proved, including qualifying remote online notarization. RSMo 474.546 recognizes certain electronic wills validly executed under the law of another qualifying jurisdiction. These rules make it important to review the exact execution process, not just whether the will was electronically signed.
