Being appointed executor of an estate in Missouri is both an honor and a legal responsibility.
For most people, this responsibility begins during one of the most emotionally difficult periods of their lives. While grieving, you are also expected to secure property, communicate with financial institutions, open probate, and manage family expectations.
If you feel overwhelmed at the outset, that is completely normal.
This guide walks you step-by-step through what to do โ beginning immediately after death and continuing through final distribution of estate assets.
Understanding Your Role As Executor
YBefore taking action, it is critical to understand what the role legally requires.
In Missouri, an executor (called a Personal Representative) is a fiduciary. This means you are legally obligated to act in the best interests of the estate and its beneficiaries.
You must safeguard assets, follow probate procedure, pay debts in the proper order, and avoid conflicts of interest โ even if you are also inheriting.
If you are unfamiliar with fiduciary responsibilities, it helps to review how estate settlement works in Missouri and what fiduciaries are responsible for.
Securing Property Immediately After Death
One of your first duties is protecting the decedentโs physical property.
If the decedent owned a home, you should visit the property promptly. Ensure doors and windows are locked and that the property is not left vacant without oversight.
If multiple people had access โ such as caregivers or contractors โ changing locks may be appropriate.
You should also:
- Confirm homeowners insurance is active
- Notify the insurer of vacancy
- Arrange lawn care or maintenance
- Remove easily transportable valuables
Do not allow family members to remove property yet โ even sentimental items. Premature distributions can create accounting issues and disputes during estate administration and probate settlement.

Ordering Death Certificates
Death certificates function as the administrative gateway to estate work.
Financial institutions, insurance companies, and government agencies will all require certified copies before releasing information or funds.
Funeral homes generally will provide death certificates to the family. You should order between 10 and 15 copies, and they generally come within a week or two. If you need more, you can order them through Missouri’s Vital Records.
Without certified copies, you will not be able to access accounts, file claims, or initiate probate efficiently.
Locating Estate Planning Documents
Next, locate the original estate planning documents.
Start with the original will โ not a photocopy. Missouri probate courts require the original for filing.
You should also search for:
- Trust agreements
- Deeds
- Insurance policies
- Financial statements
- Safe deposit box keys
If a trust exists, many assets may pass outside probate.
Understanding the difference between probate and non-probate assets early will shape your responsibilities.
If needed, review how probate differs from trust administration in Missouri estate plans.
Determining Whether Probate Is Required
Not every estate requires probate.
Probate is only necessary when assets are titled solely in the decedentโs name without beneficiary designations.
Examples:
- Sole bank account โ Probate
- Trust-owned home โ No probate
- TOD account โ No probate
Missouri also allows Small Estate Affidavits for qualifying estates.
If youโre unsure which process applies, review Missouri small estate affidavits versus full probate administration.
Overwhelmed By The Probate Process?
Most executors have never handled probate before โ and the process can quickly become technical.
TrustFully assists Missouri executors with:
- Opening probate estates
- Filing court documents
- Identifying assets
- Handling creditor claims
- Distributing inheritances properly
Opening Probate
If probate is required, you must file in the county where the decedent resided.
This involves submitting:
- The original will
- Death certificate
- Petition for appointment
Once approved, the court issues Letters Testamentary โ granting you authority to act on behalf of the estate.
You should not attempt to transfer or liquidate assets before receiving this authority.
Identifying & Inventorying Assets
After appointment, you must prepare a formal Inventory of Assets.
This requires identifying everything the decedent owned, including:
- Bank accounts
- Real estate
- Vehicles
- Investments
- Personal property
You may need to review mail, tax returns, and financial records to locate assets.
This process often overlaps with broader digital asset and online account identification within an estate.

Handling Creditors
Missouri law requires executors to notify creditors through formal publication.
Creditors then have a limited period to file claims.
You must evaluate each claim and pay valid debts in statutory priority order.
Improperly paying creditors โ or distributing funds before claims close โ can create personal liability.e.
Managing Real Estate
If the estate includes real estate, you must maintain the property.
This includes:
- Insurance
- Utilities
- Upkeep
- Security
You may need court approval before selling property, depending on the willโs authority provisions.
Executors often underestimate the time and logistics involved in property management. taxes, you, as the executor or trustee, will be personally responsible for those taxes.
Tax Responsibilities
You may need to file:
- Final individual income tax returns
- Estate income tax returns
- Federal estate tax returns (if applicable)
Tax compliance is part of fiduciary duty.
Failure to file returns can delay closing probate.
Distributing Assets
Distributions occur only after:
- Creditor claims are resolved
- Taxes are filed
- Court approvals are obtained
If no will exists, Missouri intestacy law governs distribution.
If applicable, review what happens when someone dies without an estate plan in Missouri.
Executor Liability
HExecutors can face liability for:
- Premature distributions
- Failure to notify creditors
- Asset mismanagement
- Conflicts of interest
You are not expected to know everything โ but you are expected to act prudently and seek guidance when necessary.
Serving as executor is a significant legal responsibility โ and you donโt have to navigate it alone.
TrustFully helps Missouri executors manage probate, protect estate assets, and fulfill fiduciary duties with confidence.
