When a loved one passes away, dealing with legal and financial matters can feel overwhelming. If they owned assets in their name alone, you will likely need to begin the probate process in St. Louis City, Missouri.

This guide explains how to start probate court in St. Louis City, what to expect, and how to avoid common mistakes—so you can move forward with clarity and confidence.

What Is Probate in Missouri?

Probate is the legal process of administering a deceased person’s estate. This typically includes:

• Validating the will (if one exists)
• Appointing a personal representative (executor or administrator)
• Identifying and valuing assets
• Paying debts and taxes
• Distributing assets to heirs or beneficiaries

If there is no will, Missouri’s intestate laws determine who inherits.

Where Do You File Probate in St. Louis City?

Probate cases are filed in the Probate Division of the Circuit Court where the decedent permanently lived (domiciled) at the time of death.

For St. Louis City, probate is handled at:

St. Louis City Probate Division
Civil Courts Building
10 N. Tucker Blvd.
St. Louis, MO 63101

Step-by-Step: How to Start Probate in St. Louis City, MO

1. Determine If Probate Is Necessary

Not every estate requires probate. You may be able to avoid it if assets were:

• Jointly owned
• Held in a trust
• Assigned to beneficiaries (payable-on-death or transfer-on-death)

However, if assets were solely in the decedent’s name, probate is required.

2. Choose the Right Type of Probate

Missouri offers several probate options depending on the estate size and timing:

• Application to Probate Will (admitting Will to probate).
• Small Estate Affidavit (estates under $40,000).
• Independent administration (less court supervision – probate within one year of death).
• Supervised Administration (court oversight required – probate within one year of death).
• Determination of Heirship (estates over $40,000 – probate more than one year from death).
• Refusal of Letters  (for surviving spouses or minor heirs when the estate is smaller).

Choosing the right path can save significant time and cost.

3. Gather Required Documents

To begin probate in St. Louis City, you’ll typically need:

• Original Last Will and Testament (if available)
• Certified death certificate (multiple copies recommended)
• List of assets (bank accounts, real estate, vehicles, investments)
• Known debts and liabilities
• Initial court forms

Having these prepared early helps avoid delays.

4. File the Petition With the Probate Court

To officially start a full estate probate within one-year of decedent’s death (and assets over $40,000), you must file:

• Petition for Letters Testamentary (if there is a will); or
• Petition for Letters of Administration (if there is no will);
• Personal Representative’s Bond – St. Louis City requires a bond for all probate assets;
• Renunciation(s) and Consent(s) to Independent Administration (if you want less court involvement in process); and 
• Death Certificate.

The court will review your filing and appoint a personal representative to manage the estate.

5. Inventory and Manage Estate Assets

Once appointed, the personal representative must:

• Identify and secure all estate assets
• Prepare a formal inventory
• Maintain and manage property responsibly

This step ensures everything is accounted for before distribution.

6. Pay Debts, Claims, and Taxes

Before distributing assets, the estate must:

• Notify creditors
• Pay valid debts and claims
• File and pay applicable taxes

Missouri law requires this process before heirs can receive distributions.

7. Distribute Assets to Heirs or Beneficiaries

After debts and expenses are resolved, remaining assets are distributed according to:

• The will, or
• Missouri intestacy laws (if no will exists)

Court approval may be required depending on the type of probate administration.

How Long Does Probate Take in St. Louis City?

The timeline depends on the estate’s complexity:

• Small Estate Affidavit: 60–90 days
• Independent Administration: 9–12 months
• Supervised Administration: 10–14 months

More complex estates or disputes can extend this timeline.

Common Mistakes to Avoid

Starting probate can be confusing, especially during a difficult time. Common mistakes include:

• Filing in the wrong jurisdiction
• Missing deadlines (like filing a will within one year)
• Choosing the wrong probate process
• Failing to properly notify creditors
• Paying the debts where claim(s) have not been properly filed
• Mismanaging estate assets

Working with a probate attorney  helps prevent costly delays.
