Common Mistakes by Executors and Successor Trustees
The errors that turn a routine Missouri estate into personal liability, and how to avoid each one.
Most people who serve as a personal representative or successor trustee do it once, for a parent, with no training and a grieving family watching. The mistakes they make are rarely dishonest. They are the predictable result of not knowing that the role carries legal duties, that the duties run on deadlines, and that a fiduciary who gets it wrong can be ordered to make up the loss from their own money. This page collects the errors we see most often in Missouri estates and trusts, what each one costs, and the step that prevents it. If you have been named to either role, our probate and trust administration pages cover the process itself; this page covers the ways it goes wrong.
Before anything else
Mistakes made in the first month
Acting before you have authority
A will names you, but only the probate court’s letters make you the personal representative. Closing accounts, selling the car or listing the house before letters issue is acting without authority, and every one of those acts can be challenged. A successor trustee has authority from the trust document, but only over assets actually titled in the trust.
Handing out property early
The jewelry to a sister, the truck to a nephew, the “small” cash gifts. Anything distributed before debts, taxes and expenses are resolved is money the fiduciary may have to replace personally if the estate turns out to be short.
Not valuing assets at death
Every asset needs a documented value as of the date of death: it drives the inventory, the fee calculation, and the heirs’ income tax basis. For real estate that means a licensed appraisal, ordered within weeks. We wrote a full post on why the date-of-death appraisal matters.
Using the decedent’s accounts
Writing checks on the decedent’s account, using their debit card for the funeral, or paying the estate’s bills from your own account and reimbursing yourself later. The estate needs its own tax identification number and its own account, and every dollar should move through it.
Missing the inventory deadline
In a supervised Missouri estate the inventory and appraisement is due within thirty days after letters unless the court extends it (RSMo § 473.233). An inventory built on guesses and assessor figures is a problem that surfaces at the final settlement.
Ignoring the trustee notice clock
A successor trustee has 120 days from accepting the role, and 120 days from learning the trust became irrevocable, to give the statutory notices to qualified beneficiaries (RSMo § 456.8-813). Most family trustees have never heard of the requirement.
Debts, claims and taxes
Mistakes in paying the estate’s obligations

Paying claims in the wrong order. Missouri ranks claims in ten classes under RSMo § 473.397: costs and expenses of administration first, then exempt property and family allowances, funeral expenses, debts and taxes due the United States, Medicaid reimbursement owed to Missouri, last-illness expenses, state and local taxes, judgments, and only then everything else. A personal representative who pays the credit card before the funeral home, in an estate that cannot pay both, has paid the wrong creditor and may owe the difference.
Paying anyone before the federal government. Federal law is blunter than Missouri’s: a representative who pays any debt of the estate before a claim of the United States is personally liable to the extent of that payment (31 U.S.C. § 3713(b)). Unpaid income tax on the decedent’s final return is the usual trap.
Paying claims that were never properly filed. In a probate estate, most claims not filed within six months after the first published notice of letters are barred forever (RSMo § 473.360). A personal representative who pays a stale claim out of politeness has spent the heirs’ money on a debt the estate did not owe.
Forgetting the tax returns. The decedent’s final Form 1040, a Form 1041 for the estate or trust in any year it has $600 or more of gross income, and Form 56 to tell the IRS who the fiduciary is. The IRS explains each on its deceased persons page and in Publication 559. Missouri has no estate or inheritance tax, but it does expect the final Missouri income return.
Assuming a beneficiary designation settles everything. Transfer-on-death accounts and beneficiary deeds pass outside probate, but Missouri’s nonprobate transfer statute can, in some circumstances, reach them to pay claims when the probate estate is insolvent. The Missouri Court of Appeals drew that line narrowly in a 2026 decision we analyzed in Estate of Hicks; a fiduciary should know which side of it the estate falls on before assuring anyone the assets are safe.
The measure of a trustee’s liability
Under RSMo § 456.10-1002, a trustee who breaches the trust owes the beneficiaries the greater of the amount needed to restore the trust to where it would have been without the breach, or the profit the trustee made from it.
That figure comes out of the trustee’s own pocket, and a court may remove the trustee as well (RSMo § 456.7-706). A personal representative faces the same exposure through a surcharge on the settlement and removal under RSMo § 473.140. Almost every one of these outcomes started as an avoidable procedural mistake.
Loyalty, records and communication
Mistakes that turn into lawsuits
Dealing with yourself
Buying the house from the estate, renting it to your own child below market, hiring your own company for repairs, or lending estate money to yourself. Even at a fair price, a transaction between a trustee and the trust is voidable by the beneficiaries unless the document, the court or the beneficiaries authorized it (RSMo § 456.8-802). Deals with a spouse, child, sibling or parent are presumed conflicted.
Commingling
Estate or trust money in a personal account, even briefly, even with every intention of sorting it out. A trustee must keep trust property separate and keep adequate records (RSMo § 456.8-810). Once funds are mixed, the presumption on any unexplained dollar runs against the fiduciary.
Going silent
Beneficiaries who hear nothing assume the worst, and the law is on their side: a trustee must keep qualified beneficiaries reasonably informed and respond to reasonable requests for information. Most petitions to remove a fiduciary begin with months of unreturned calls, not with theft. A short written update every quarter prevents most of them.
Favoring one beneficiary
A fiduciary who is also an heir, resolving every close question in their own favor: which items are “personal effects,” who gets to occupy the house rent-free, when to sell. Impartiality is a duty, and a pattern of small tilts is easy to prove from the records.
Following instinct over the document
“Dad would have wanted” is not a distribution standard. The will or trust controls, including provisions the family finds unfair. A fiduciary who departs from the instrument to do what seems right has substituted their judgment for the decedent’s, which is exactly what the law forbids.
Letting assets sit
Two years of cash in a non-interest account, a vacant house without insurance, a brokerage account never reviewed. Missouri applies the prudent investor standard to trustees (RSMo § 469.902), and neglect of property is mismanagement for a personal representative.
Closing the estate
Mistakes at the end
No settlement, no discharge
A supervised personal representative must file settlements annually on the anniversary of letters and a final settlement when administration is complete (RSMo § 473.540), with vouchers for expenditures over $75. An independent personal representative files a statement of account under RSMo § 473.840. Until that is done and approved, the fiduciary is not discharged and the exposure continues.
Distributing without releases
Money goes out, and then a beneficiary questions the accounting. A trustee’s report that adequately discloses the administration starts a one-year clock on claims against the trustee (RSMo § 456.10-1005). Distributing without a final report, and without written receipts and releases, gives up that protection for nothing.
Taking a fee without the paperwork
A personal representative is entitled to compensation on the statutory schedule in RSMo § 473.153, and a trustee to reasonable compensation. Both must be disclosed and, for a personal representative, approved. A fee quietly deducted from a distribution is the kind of item that reopens a closed estate.

About the attorney

Derek spent three years as a Vice President and Estate Settlement Officer at Bank of America Private Bank, administering estates and trusts as the corporate fiduciary. That work runs under audit, with procedures designed to prevent every mistake on this page: separate accounts from day one, date-of-death valuations before anything moves, claims paid in statutory order, written reports to beneficiaries on a schedule.
Family fiduciaries do not inherit those systems. Most of what goes wrong in a Missouri estate is something a corporate trustee’s checklist would have caught in the first month, which is why the fix is usually procedural rather than dramatic, and why the earlier the conversation, the cheaper it is.
He also drafts wills and trusts, and litigated challenges to them and to fiduciaries as a partner at Howard Haake from 2014 to 2022. He has seen these mistakes from the fiduciary’s side, the beneficiary’s side, and the bench.
Common questions
Frequently asked questions
I already made one of these mistakes. What now?
Stop, document, and fix it before anyone else finds it. Most early mistakes are correctable at little cost if they are corrected promptly: money moved into a personal account can be moved back with a paper trail; an early distribution can be recovered or offset against that beneficiary’s final share; a missed trustee notice can be sent late with an explanation.
What makes a correctable mistake into a claim is concealment. A fiduciary who discloses the error in the next report, shows the correction, and explains it is in a very different position from one whose beneficiaries discover it in the bank records. Missouri’s trust code expressly lets beneficiaries ratify or release a trustee’s conduct (RSMo § 456.10-1009), and a court can approve a personal representative’s actions after the fact. Both are far easier to obtain when the fiduciary raised the issue.
If the mistake involved a distribution that cannot be recovered, a sale to yourself or a relative, or a loss from investment neglect, get advice before the next filing. The estate settlement work we do most often is exactly this: taking over an administration partway through and putting it on a defensible footing.
Can I really be held personally liable? I was just trying to help.
Yes. Good faith is not a defense to a breach of fiduciary duty; it goes to the remedy, not to liability. A personal representative who distributes before paying a valid claim, or pays claims out of order in an insolvent estate, can be surcharged for the shortfall on the settlement. A trustee is liable under RSMo § 456.10-1002 for the greater of the loss to the trust or the trustee’s profit, and under RSMo § 456.10-1001 a court can compel performance, enjoin the trustee, order an accounting, reduce or deny compensation, or remove the trustee.
Federal tax claims are the sharpest edge. Under 31 U.S.C. § 3713(b), a representative who pays other debts before a claim of the United States is personally liable to the extent of those payments. The IRS does not need to prove bad faith.
The reason this rarely happens to well-advised fiduciaries is that the protections are procedural: a separate account, a documented valuation, claims paid in order after the bar date, reports delivered on time, and releases collected before distribution. Each one closes a door.
What is the difference between an executor and a successor trustee?
The source of authority and the assets controlled. An executor, called a personal representative in Missouri, is nominated in a will but has no authority until the probate court issues letters. The court supervises, filings are public, and the deadlines in Chapter 473 apply. A successor trustee takes authority from the trust document itself when the prior trustee dies or becomes incapacitated, with no court appointment and ordinarily no court supervision, and controls only the assets titled in the trust.
The same person often holds both roles, running a probate for assets the decedent never moved into the trust while administering the trust for everything that was funded. Our post on executor versus successor trustee duties walks through where the two roles diverge; our probate and trust administration pages cover each process.
Both are fiduciaries, and the core duties of loyalty, prudence, impartiality, record-keeping and following the instrument are the same. The mistakes on this page apply to both unless stated otherwise.
How soon does the estate need its own bank account and tax number?
Immediately after letters issue, or, for a trustee, immediately on accepting the trusteeship. The estate or trust obtains its own employer identification number from the IRS (free, online, in minutes) and opens an account in the fiduciary’s name as such. The decedent’s social security number should not be used for anything that happens after death.
Every receipt goes into that account and every disbursement comes out of it. Funeral expenses paid personally before the account exists are reimbursable as a class-four claim under RSMo § 473.397, with receipts. What should never happen is a running tab of personal outlays and informal repayments; that pattern is indistinguishable, in the records, from a fiduciary helping themselves.
Keep the account statements, every invoice, and a simple ledger. Missouri requires vouchers for settlement items over $75 (RSMo § 473.543), and beneficiaries are entitled to an accounting from a trustee. A fiduciary who cannot explain a transaction loses the argument about it.
A beneficiary is pressuring me to distribute now. Can I make a partial distribution?
Sometimes, and carefully. In a probate estate, no distribution is safe until the six-month claims period under RSMo § 473.360 has run and the known claims and taxes are provided for. After that, a partial distribution is common where the estate is clearly solvent, the remaining liabilities are known and reserved, and the court approves it or the administration is independent.
For a trust, the same logic applies without the statutory clock: distribute only what is clearly surplus to all known and reasonably anticipated liabilities, including the income tax on the trust’s own earnings and any federal estate tax exposure. Get a written receipt for every partial distribution, and state in it that the distribution is on account of the beneficiary’s share and subject to adjustment in the final accounting.
What a fiduciary should never do is distribute to end an argument. A beneficiary who is overpaid rarely returns the money voluntarily, and the fiduciary, not the beneficiary, is the one the court looks to for the shortfall.
I am also a beneficiary. Can I still serve, and what should I watch for?
Yes; it is the normal situation in a family estate. The law does not forbid a beneficiary from serving, but it holds the fiduciary-beneficiary to the same duty of impartiality as a stranger would owe, and every decision that favors the fiduciary’s own share will be examined with that in mind.
The practical rules: keep the personal-effects division transparent and in writing; do not occupy or use estate property without paying fair rent or getting the other beneficiaries’ written consent; do not buy estate assets without either the instrument’s authorization, court approval, or all beneficiaries’ informed written consent, since a sale to the trustee is voidable under RSMo § 456.8-802; and resolve genuinely close questions by asking rather than deciding.
Where the family is already in conflict, consider whether a neutral should serve instead, or whether the fiduciary should engage counsel whose advice goes to the estate rather than to the fiduciary personally. Our beneficiary representation page describes the other side of that relationship.
The house is the main asset. What are the specific mistakes there?
Four, in order of frequency. Not obtaining a date-of-death appraisal, which fixes the inventory value and the heirs’ income tax basis when the house is later sold; we explain the cost of skipping it in our post on date-of-death valuation. Letting the insurance lapse or failing to tell the carrier the house is vacant, which can void coverage. Allowing a family member to live there rent-free without the other beneficiaries’ consent. And selling to a relative, or to the fiduciary, at a price nobody else was offered.
If someone is occupying the house without a right to, Missouri’s new expedited removal statute may apply; we covered what it requires in our post on Section 534.602. If the house passed by beneficiary deed, it is not a probate asset and the personal representative has no authority over it, but the grantee still needs the appraisal and should understand the creditor rules discussed in Estate of Hicks.
Track every dollar spent on the house after death separately. Post-death improvements add to basis; ordinary carrying costs are administration expenses. Mixing the two costs the heirs money at closing.
What records do I have to keep, and for how long?
Everything, and longer than you would think. At a minimum: the letters or trust acceptance; the death certificate; the inventory and every valuation supporting it; bank statements for the estate account from opening to closing; every invoice, receipt and canceled check; the claims filed and how each was resolved; the tax returns and the IRS and Missouri correspondence; the notices sent to beneficiaries and creditors; every report or settlement; and signed receipts and releases from each beneficiary.
Missouri requires a trustee to keep adequate records under RSMo § 456.8-810, and a personal representative’s settlements must be supported by vouchers under RSMo § 473.543. Beneficiaries can bring claims for years after the administration closes unless a proper report started the one-year clock under RSMo § 456.10-1005; otherwise the outside period is five years from the trustee’s removal, resignation or death, the end of the beneficiary’s interest, or the termination of the trust.
Keep the file for at least five years after the final distribution, and keep the date-of-death appraisal permanently; the heirs will need it whenever the property is sold.
Can I be paid for this work?
Yes. A personal representative is entitled to the minimum compensation set by the schedule in RSMo § 473.153, a percentage of the personal property and real estate proceeds that steps down as the estate grows, and may ask the court for more where the work justified it. A trustee is entitled to reasonable compensation unless the trust provides otherwise, and must disclose the source and amount of it in the trustee’s report.
Fees are taxable income to the fiduciary; an inheritance generally is not. A fiduciary who is also the sole or principal beneficiary usually waives the fee for that reason. A fiduciary who is one of several beneficiaries should take the fee openly, on the schedule, with approval, rather than reasoning that the extra work “evens out” through informal advantages.
Never net a fee against a distribution without disclosing it, and never pay yourself before the claims period has run and the estate’s solvency is known. Compensation is a claim in the first class, but it is still a claim, and the court can reduce or deny it for a fiduciary who breached.
When should a fiduciary hire a lawyer, and who pays?
When any of these is present: real estate, a business interest, a taxable estate, a beneficiary with creditors or a disability, an out-of-state asset, an unfunded trust, an ambiguous document, a family in conflict, or a claim the fiduciary is not sure is valid. A small solvent estate with liquid assets, one or two cooperative beneficiaries and a clear will can often be handled with limited help, and Missouri’s small estate affidavit procedure exists for estates under $40,000.
The estate or trust ordinarily pays for the fiduciary’s legal advice as an administration expense, a first-class claim under RSMo § 473.397. Attorney compensation in a probate estate follows the same statutory schedule as the personal representative’s under § 473.153. Getting advice, in other words, rarely comes out of the fiduciary’s own pocket; getting it wrong frequently does.
One caution: the lawyer for the estate represents the fiduciary in that capacity, not the beneficiaries. A beneficiary who wants independent advice should retain their own counsel, which is what our beneficiary representation practice provides.
How long does all of this take, and what makes it longer?
A straightforward supervised Missouri probate runs roughly nine to twelve months, driven by the six-month creditor period plus the time to file and approve the final settlement. Independent administration can close a little sooner. A funded trust with liquid assets can be finished in a few months, since there is no statutory claims window.
What extends either: real estate to sell, a business interest to value, a federal estate tax return (which alone typically holds an administration open past nine months while the IRS reviews it), an out-of-state property requiring ancillary administration, a will or trust contest, a beneficiary who cannot be located, and, above all, a fiduciary who does not do the work. The probate page sets out the statutory deadlines in order.
The mistakes that most often add a year are early distributions that have to be unwound, a house sale to a relative that has to be set aside, and an accounting that cannot be reconstructed because the records were never kept.
Can I resign, or be removed?
Both. A personal representative may resign with the court’s permission after filing a settlement, and a trustee may resign on notice to the qualified beneficiaries and co-trustees or with court approval (RSMo § 456.7-705). Resignation does not erase liability for what happened before it.
Removal is the beneficiaries’ remedy. A court may revoke a personal representative’s letters for neglecting duties, wasting or mismanaging the estate, or being unsuitable to execute the trust, among other grounds (RSMo § 473.140). A court may remove a trustee for a serious breach, for persistent failure to administer the trust effectively, or where co-trustees cannot cooperate (RSMo § 456.7-706).
If you are a beneficiary considering that step, or a fiduciary facing it, our contested estates page describes how those proceedings work. Many removal petitions are avoided by the fiduciary simply starting to communicate and account.
