Intestate Succession in Missouri: Filing Requirements

When someone dies in Missouri without a will, their property doesn't just disappear but the state decides who gets it. That process is called intestate succession, and it follows a strict set of rules written into Missouri law. If you're dealing with a loved one's estate and there's no will in place, understanding how intestate succession works in Missouri can save you months of confusion, family conflict, and legal headaches.

What Does Intestate Succession Actually Mean in Missouri?

"Intestate" simply means a person died without a valid will. When that happens in Missouri, the state's intestate succession laws kick in. These laws, found in Missouri Revised Statutes Chapter 474, lay out a specific order of who inherits the deceased person's probate property.

This doesn't mean the state takes everything. It means the state has a default plan. The problem is, that plan may not match what the deceased person would have wanted. A spouse might get less than expected. Children from a previous marriage might be left out or included when no one anticipated it.

Who Inherits Under Missouri's Intestate Succession Rules?

Missouri's intestate succession laws follow a hierarchy. The surviving spouse's share depends on who else survives the deceased:

Surviving Spouse With Children

If the deceased had a surviving spouse and all children are also children of that spouse, the surviving spouse inherits the first $20,000 of the intestate estate plus half of the remaining balance. The children split the other half equally.

If the deceased had children from a different relationship, the surviving spouse only gets half of the intestate estate no $20,000 preference. The other half goes to all of the deceased's children equally.

Surviving Spouse With No Children

If there's a surviving spouse but no children or grandchildren, the spouse inherits the first $20,000 plus half of the remaining balance. The other half goes to the deceased's parents, then siblings, and so on down the line.

No Surviving Spouse

Without a spouse, the estate passes to children equally. If there are no children, it goes to parents, then siblings, then grandparents, then aunts and uncles, and eventually to the state of Missouri through a process called "escheat." This last outcome is rare, but it does happen when absolutely no heirs can be found.

What Property Passes Through Intestate Succession and What Doesn't?

Not everything the deceased owned goes through the intestate succession process. Only "probate property" is affected. That includes:

Real estate owned solely by the deceased
Bank accounts in the deceased's name only, without a payable-on-death designation
Personal property like vehicles, furniture, and valuables
Business interests held individually

Property that does not pass through intestate succession includes:

Life insurance proceeds with a named beneficiary
Retirement accounts with a named beneficiary
Jointly owned property with rights of survivorship
Transfer-on-death or payable-on-death accounts
Assets held in a living trust

Understanding this distinction matters because families sometimes assume everything goes through the court process when, in reality, much of the estate may pass directly to named beneficiaries outside of probate.

How Does the Intestate Probate Process Work in Missouri?

The intestate succession process in Missouri runs through the probate court. Here's how it typically unfolds:

Someone petitions the court. A family member or interested party files a petition to open probate. The court then appoints a personal representative (also called an executor) to manage the estate. You can learn more about how to begin this by reviewing Missouri's probate filing requirements.
The personal representative identifies and gathers assets. This includes bank accounts, real estate, vehicles, and personal property. They must also notify creditors.
Debts and expenses get paid. Before any heirs receive property, the estate must pay valid debts, taxes, and administrative costs.
The court determines heirs. Without a will naming beneficiaries, the probate court applies Missouri's intestate succession statute to determine who inherits. This step is built into the overall legal steps for probate in Missouri.
Remaining assets are distributed. After debts are satisfied, the personal representative distributes the remaining property to the heirs according to the statutory formula.

Depending on the estate's complexity, this process can take anywhere from a few months to over a year. Estates with contested heirship, business interests, or real estate in multiple states tend to take longer.

What Documents Does the Probate Court Need for an Intestate Estate?

Filing for probate without a will requires specific paperwork. The court will need the death certificate, a petition for administration, a list of heirs, and an inventory of the deceased's assets. The exact requirements vary slightly by county. You can review what probate courts require and the full list of Missouri probate forms to make sure you're prepared before filing.

What Are the Most Common Mistakes Families Make With Intestate Estates?

Families navigating intestate succession in Missouri often run into avoidable problems:

Assuming the spouse gets everything. Missouri law doesn't give the entire estate to the surviving spouse when children are involved. Many families are surprised by this.
Ignoring non-probate assets. Families sometimes spend months in probate court over assets that don't even need to go through the process.
Waiting too long to file. Missouri doesn't set a strict deadline to open probate, but delays can cause problems with creditor claims, property maintenance, and tax filings.
Not notifying all potential heirs. Missouri law requires that all heirs be identified and notified. Missing an heir even one the family didn't know about can derail the process.
Distributing property before paying debts. The personal representative is legally required to pay estate debts before distributing assets. Skipping this step can create personal liability.

How Can You Avoid Intestate Succession Problems?

The simplest way to avoid Missouri's default inheritance plan is to create a valid will. But if you're already dealing with an intestate estate, here are practical steps you can take:

Get organized early. Gather the death certificate, account statements, property deeds, and any documents that show who the heirs might be.
Talk to the probate court in the county where the deceased lived. Each Missouri circuit court may have slightly different local procedures.
Identify all heirs as soon as possible. This includes children from previous marriages, adopted children, and any children born outside of marriage who may have legal standing.
Don't distribute anything until the court authorizes it. Even if everyone agrees on who should get what, the probate process must be followed.
Consider whether small estate procedures apply. Missouri allows simplified probate for estates under certain thresholds, which can save time and money.
