How Probate Works in St. Louis County: A Step-by-Step Guide for Executors

Does the Estate Actually Need Probate?

Before you start filing anything, figure out whether probate is even necessary. Not every estate goes through the process.

In Missouri, property can bypass probate entirely if it was held in a living trust, titled with a transfer-on-death (TOD) deed, jointly owned with rights of survivorship, or set up with a payable-on-death designation on bank accounts or insurance policies.

If the house was in the deceased person's name alone, with none of those designations in place, you're almost certainly looking at probate. That's the scenario most families I work with are dealing with.

One thing worth mentioning here: a lot of people confuse the will with a way to avoid probate. It's not. A will actually has to go through probate to be executed. The will tells the court what the deceased person wanted. Probate is the process that makes it happen.

Which Type of Probate Are You Dealing With?

Missouri doesn't have a one-size-fits-all probate process. The path you take depends on the size of the estate and when you're filing.

Small Estate Affidavit is the fastest route. If the estate's total value (minus liens and debts) is under $40,000, you may qualify. This can wrap up in 60 to 90 days. There's a catch, though. If the value exceeds $15,000, you're still required to publish a notice to creditors in a local newspaper.

Spousal Refusal of Letters applies when the surviving spouse inherits everything and the estate falls below certain thresholds. In St. Louis County, some judges get hesitant to approve this if probate assets exceed around $24,000. That number isn't in the statute, it's more of a local practice. Worth knowing if you're on the edge.

Independent Administration is the most common path for straightforward estates filed within one year of death. Less court supervision, fewer hearings, and the executor has more autonomy to manage things. Typical timeline is 8 to 12 months.

Supervised Administration means the court is involved in every major decision. This happens in contested situations, when heirs disagree, or when the court has concerns about how the estate is being handled. Expect 10 to 14 months or longer.

Determination of Heirship is the route when more than a year has passed since the death. Different procedural requirements, but usually resolves in 3 to 4 months.

If you're not sure which path applies, a probate attorney can sort that out quickly. And in Missouri, the law generally requires a licensed attorney to represent the estate in probate proceedings anyway, so you'll want one in your corner regardless. Once the home is ready to sell, understand the federal capital gains rules for Missouri heirs before you commit to a price or strategy. Stepped-up basis changes the math significantly.

The Probate Process in St. Louis County, Step by Step

Here's what the timeline actually looks like once you get started.

Open the Case with the Court

Everything begins with filing a petition at the St. Louis County Probate Court. It's on the third floor of the County Government Building in Clayton. Bring the original will (if there is one), certified copies of the death certificate (get more than you think you'll need), and any documentation of the estate's assets.

The court will review the petition and appoint a personal representative. If the will names an executor, the court typically honors that. If there's no will, or if the named executor can't serve, the court appoints an administrator, usually the next of kin.



Practical note: arrive 15 to 20 minutes early. There's a security screening, parking can be tight, and you don't want to start this process already stressed about being late.

Inventory Everything the Estate Owns

Once you're appointed, your first real task is creating a detailed inventory of every asset in the estate. Real property, bank accounts, vehicles, investments, personal property of significant value. All of it.

The court requires this inventory, and it needs to be thorough. Missing an asset doesn't make it go away. It just creates problems later when you're trying to close the estate and something surfaces that wasn't accounted for.



For real estate specifically, you'll need an appraisal to establish fair market value. This matters for two reasons: the court needs it to approve any future sale, and the IRS uses the date-of-death value as the "stepped-up basis" for tax purposes. That stepped-up basis is one of the few financial bright spots in this process, so make sure the appraisal is done correctly.

Notify Creditors and Settle Debts

Here's where the mandatory waiting comes in. Missouri law requires you to publish a notice to creditors in a newspaper of general circulation. Once that notice is published, creditors have six months to file claims against the estate.

Six months. There's no way around that timeline. It's baked into the law to protect creditors, and it's the single biggest reason probate takes as long as it does.



During that window, you'll review any claims that come in, pay the legitimate ones from estate funds, and dispute the ones that don't hold up. You're also responsible for keeping up with property taxes, insurance, and basic maintenance on any real estate in the estate during this period. The costs come out of the estate, not your pocket, but they add up fast on a house that's sitting empty.

Decide What to Do with the Property

This is usually the biggest decision executors face, and it's where I come in most often.

You generally have three options. Keep the property (if one heir wants it and can buy out the others). Rent it out while the estate settles. Or sell it.

Most families I work with in St. Louis County end up selling. Maintaining a vacant house costs money every month between taxes, insurance, utilities to prevent frozen pipes, and lawn care. And the longer a house sits empty, the more vulnerable it becomes to deterioration and break-ins.

If you're going the sale route, know that the court typically needs to approve the sale. The level of court involvement depends on whether you're in independent or supervised administration. Under independent administration, you have more flexibility to accept an offer and move forward. Under supervised administration, the court reviews offers and may require a hearing.

There are a few ways to sell a probate property. You can list it on the open market with a real estate agent, sell directly to a cash buyer, or in some cases, sell it to one of the heirs. Each approach has tradeoffs around price, timeline, and hassle. I wrote a more detailed breakdown of those options in my guide on how to sell a St. Louis County probate home fast, which is worth reading if the property is a significant part of the estate.  You can also check out how to sell an inherited home without stress.

Distribute What's Left and Close the Estate

Once debts are paid, property is sold or transferred, and the creditor window has closed, you can distribute the remaining assets to the beneficiaries. If there's a will, you follow its instructions. If there's no will, Missouri's intestacy laws determine who gets what.

After distributions are made, you file a final settlement with the court. Once approved, the estate is officially closed and your role as executor is done.



The whole process, start to finish, typically runs 6 to 12 months for a standard estate in St. Louis County. Complex situations with contested wills, multiple properties, or creditor disputes can stretch well beyond a year.

Mistakes That Cost Executors Time and Money

I've watched enough families go through this to know where people trip up. A few of the common ones:

Waiting too long to start. In Missouri, the will has to be filed with the probate court within one year of death. But beyond the legal deadline, delay creates practical problems. An empty house deteriorates. Insurance gets more expensive or lapses entirely. Property taxes pile up. The sooner you get the process moving, the fewer headaches down the road.

Not getting the property secured early. Vacant homes attract problems. Change the locks, make sure the insurance policy is updated to reflect that the property is unoccupied (standard homeowner's policies often don't cover vacant properties), and have someone check on it regularly. I've seen estates lose thousands of dollars because a pipe burst in an empty house and nobody noticed for weeks.

Pricing the property based on emotion instead of data. The house your parents lived in for 40 years has sentimental value. The market doesn't care. Overpricing a probate property leads to months of sitting on the market while you're paying carrying costs from the estate. Get a proper appraisal, look at comparable sales, and price it based on what buyers are actually paying in that neighborhood right now.



Skipping the attorney. I know legal fees aren't fun. But probate in Missouri is technical and deadline-driven. Mistakes can create personal liability for the executor. The cost of an attorney is a fraction of what a mishandled estate can cost everyone involved.

Frequently Asked Questions

How long does probate take in St. Louis County?

A straightforward estate with no disputes typically takes 6 to 12 months. The mandatory six-month creditor notification period is the biggest factor. Contested estates or those with complicated assets can take 12 to 18 months or longer.

How much does probate cost in Missouri?

Executor fees in Missouri follow a sliding scale. It's 5% on the first $5,000, 4% on the next $20,000, 3% on the next $75,000, and the percentage decreases from there. Court filing fees range from $50 to $1,200 depending on estate size. Attorney fees vary but most probate attorneys in St. Louis County charge a flat fee, often in the $3,000 to $7,500 range for a standard administration.

Can you sell a house while it's still in probate?

Yes, but you need court approval. The level of approval depends on your type of administration. Under independent administration, the process is more streamlined. Under supervised administration, the court reviews and approves offers. Either way, selling during probate is common and often the smartest financial move for the estate.



Can probate be avoided in St. Louis County?

Yes, with proper estate planning done before death. Living trusts, TOD deeds, joint ownership with survivorship rights, and payable-on-death designations all allow property to transfer outside of probate. If you're reading this because you just went through the process and want to make sure your own family doesn't have to, talk to an estate planning attorney about setting those up.
