How Long Does Probate Take in Missouri? (6-12 Months)

For many Missouri families navigating the loss of a loved one — after determining when probate is required — one question looms large: “How long will probate take?” While every case is unique, understanding the typical timeline and factors that influence it can help you better prepare for the journey ahead.

What is Probate and Why Does it Take Time?

Probate is the legal process through which a deceased person’s estate is settled and distributed. In Missouri, this process is governed by Chapter 473 of the Missouri Revised Statutes, which outlines specific steps and requirements that must be followed.

The overview of the probate process in Missouri can seem daunting at first glance. This court-supervised procedure involves multiple steps, including:

Validating the will (if one exists)
Appointing an executor or administrator
Identifying and valuing assets
Paying debts and taxes
Distributing remaining assets to beneficiaries

The Typical Timeline for Probate in Missouri

On average, a straightforward probate case in Missouri takes between six months to a year to complete. However, more complex estates can take significantly longer. Here’s a breakdown of the typical timeline:

Initial Filing and Appointment (1-2 months)

The process begins with filing the will and petition for probate with the appropriate Missouri probate court. Under RSMo 473.260, the estate’s assets legally transfer to heirs upon death, but the executor must be officially appointed to manage them in many cases.

Inventory Period (2-3 months)

According to RSMo 473.263, the executor has the right to take possession of estate assets. During this time, they must:

Locate and inventory all assets
Obtain professional appraisals when necessary
Secure and maintain property
Set up estate accounts

Creditor Claim Period (6 months)

Missouri law (RSMo 473.360) establishes a six-month period during which creditors can file claims against the estate. This mandatory waiting period cannot be shortened, making it one of the primary reasons full probate takes six months at minimum.

Why Probate Takes So Long: Common Causes of Delay

Most people want probate to be done as quickly as possible, but several factors can extend the timeline well beyond the six-month minimum. Understanding these common causes of delay can help you anticipate problems and take steps to keep the process moving.

Paperwork and Procedural Requirements

Managing probate-required paperwork is a significant undertaking. There are structured timelines, court-imposed deadlines, required filings, and notifications that must be completed in a specific order. Missing a deadline or filing an incomplete document can set the process back weeks.

Complexity of the Estate

Estates with numerous or complicated assets simply take longer to administer:

Multiple real estate properties requiring appraisal or sale
Outstanding debts or liens that must be resolved
Business interests requiring valuation and potentially ongoing management
Tax complications, including estate tax returns or back taxes
Assets in multiple states, which may require ancillary probate

Probate Court Caseload

Most Missouri probate courts are dealing with high caseloads and limited staff. Depending on the county, scheduling hearings and receiving court orders can add weeks or months to the timeline. Court processing times vary — you can find contact information for your local court on our county resources page.

Challenges to the Will

Heirs, beneficiaries, and those who expected to be beneficiaries can object to and challenge the will's validity. While Missouri law sets specific time periods for filing objections, will contests can add months or even years to the process. Common challenges include claims that the will maker:

Lacked testamentary capacity (the legal or mental ability to make a will)
Was subject to undue influence (wrongful pressure from another person)
Was a victim of fraud or forgery
Did not execute the will with proper legal formalities

Creditor Notification and Claims

Missouri law requires a six-month period for creditors to file claims against the estate (RSMo 473.360). This mandatory waiting period cannot be shortened. If creditors file disputed claims, resolving those disputes adds additional time.

Family Conflict and Uncooperative Heirs

Disputes between family members — over asset distribution, the executor's decisions, or the validity of the will — are among the most common reasons probate drags on. Missing or unresponsive heirs can also create delays, as the court may require additional efforts to locate and notify them.

Failure to Gather Documents Early

Executors who delay gathering critical documents — death certificates, financial account statements, property deeds, insurance policies — inevitably slow down the entire process. The inventory period depends on having this information readily available.

Small Estate Alternatives

Not all estates require full probate. Missouri offers a simplified process for smaller estates through RSMo 473.097. You may be eligible to use a Small Estate Affidavit in Missouri if:

The estate’s value is under $40,000
All debts have been paid
30 days have passed since the death

This streamlined process can often be completed in just a few weeks, rather than months.

There are other short-form probate processes as well, such as a Determination of Heirship (where the assets are > $40,000 and it has been more than 1 year since death), and various Refusal of Letters applications reserved for spouses, minor children, and creditors of the estate.

Tips for Speeding Up the Probate Process

While you cannot eliminate the mandatory six-month creditor period, there are practical steps you can take to prevent unnecessary delays and keep the process moving as efficiently as possible:

Hire an experienced probate attorney early. An attorney who regularly handles Missouri probate cases will know the local court’s procedures and expectations, helping you avoid common mistakes that cause delays.
Gather critical documents immediately. Before filing, collect death certificates (order multiple copies), the original will, financial account statements, property deeds, vehicle titles, insurance policies, and recent tax returns. The sooner you have these in hand, the faster the inventory can be completed.
Open an estate bank account promptly. All estate income and expenses should flow through a dedicated account. This makes record-keeping cleaner and avoids complications at closing.
Communicate proactively with heirs and beneficiaries. Many disputes arise from a lack of information. Regular updates — even brief ones — can prevent misunderstandings from escalating into formal objections.
Address creditor claims as they arrive. Do not let claims pile up. Review each one promptly, pay valid debts, and formally reject invalid claims within the statutory period.
Stay on top of court deadlines. Missing a filing deadline can result in weeks of delay. Use a calendar system to track every required filing and court date.
Keep meticulous records. Detailed records of every transaction, communication, and decision protect you as executor and make the final accounting much smoother.
