What Does a Successor Trustee Do After Someone Dies?
By Joshua Harden, Attorney | Memento Mori Law
A practical guide to trust administration after death, including trustee duties, assets, beneficiaries, debts and records in Kansas and Missouri.
Key Points at a Glance
A successor trustee takes over when the trust terms and applicable law authorize the transition.
The trustee must identify and safeguard trust assets, follow the trust, and meet fiduciary duties.
Notices, records, taxes, debts, and beneficiary communications may require attention.
Trust administration differs from probate, but it is not necessarily automatic or free of legal obligations.
When a successor trustee takes over
A successor trustee may become responsible for administering a trust when the prior trustee dies, resigns, or becomes unable to serve under the terms of the document. Being named as successor does not mean the person should immediately distribute every asset. The trustee must first understand the trust, confirm authority, and identify property actually held in or governed by the trust.
Consider a parent who dies with a trust naming one child as successor trustee. The family may expect immediate checks, but the trustee may need to secure a home, collect statements, evaluate debts and expenses, and determine whether separate probate administration is required for assets left outside the trust.
The trustee's duties to beneficiaries
Trustees are fiduciaries. They generally must act in accordance with the trust terms and applicable law, manage property prudently, avoid improper self-dealing, and address beneficiaries' rights to information. The specific obligations depend on the trust and circumstances.
A trustee who is also a beneficiary should be especially careful about conflicts. Keep estate or trust money separate from personal funds, document decisions, and communicate appropriately. Family members may disagree about timing, but the trustee's responsibilities are not simply to satisfy the loudest request.
Identify and protect trust property
Start with the trust instrument, amendments, deeds, account statements, beneficiary information, and any schedule of trust assets. Verify legal ownership rather than assuming an asset belongs to the trust because it appears on an old list. A house, brokerage account, or business interest may require different steps to secure and manage.
Maintain insurance, safeguard valuable property, address urgent bills, and keep a ledger of receipts and disbursements. If property must be sold, review the trustee's authority and the trust's distribution instructions before making commitments.
Taxes, debts, and distributions
Trust administration can involve creditor issues, tax filings, valuation, and coordination with a probate estate. The trustee should determine which obligations apply before making final distributions. A trust does not automatically eliminate every tax or creditor question.
Some trusts call for outright distributions; others continue for a spouse, children, or other beneficiaries. The trustee should distinguish between the beneficiaries' expectations and the written terms. An accounting or other documentation may be required or advisable before closing the administration.
When to ask for professional help
Professional guidance can be valuable when real estate is involved, beneficiaries disagree, the trust is ambiguous, assets are missing, or a trustee is concerned about personal liability. An attorney and tax professional may have different but complementary roles.

What Beneficiaries Can Expect
Beneficiaries may want to know when distributions will occur and what information they can receive. The trust terms and applicable law govern rights to notices, information, and accountings. A trustee should not make unsupported promises before identifying assets and obligations.
Communication can be professional without being adversarial. Explain what has been found, which steps remain, and why certain decisions cannot yet be finalized. Document important conversations and decisions.
Common Trust Administration Mistakes
Problems often arise when a successor trustee assumes that all of the deceased person's property belongs to the trust, uses personal accounts for trust expenses, fails to maintain insurance, or distributes assets before understanding obligations.
A trustee should also avoid conflicts when purchasing trust property or making distributions that affect their own interests. Early advice can be less costly than trying to correct an unauthorized transaction after beneficiaries object.
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
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.
