What Are Surviving Spouse Rights in Missouri?

When a husband or wife dies in Missouri, the surviving spouse rights in Missouri law recognizes go well beyond whatever the will says. A widow or widower is entitled to a share of the estate through intestate succession or an elective share against the will, plus exempt household property, a homestead allowance capped at $15,000, and a family allowance during probate. Each of these protections carries its own filing deadline, and missing a window means losing that right for good.

If There Is No Will

When a Missouri resident dies without a will, the surviving spouse’s share depends on whether the deceased left descendants and who those descendants’ other parent is.

No surviving children or other descendants: the surviving spouse takes the entire probate estate.
All surviving children are also children of the surviving spouse: the surviving spouse takes the first $20,000 in value, then half the remainder.
At least one surviving child is from a different relationship: the surviving spouse takes half the estate.

Whatever portion is not the spouse’s goes to the children or their descendants.¹ These shares only apply to property that actually passes through probate. Life insurance with a named beneficiary, retirement accounts, joint accounts, and transfer-on-death deeds move under their own rules.

Taking Against the Will

A will can leave a spouse nothing on paper, but Missouri gives the survivor the right to reject those terms and claim a guaranteed portion instead. This is called the elective share, and it depends on whether the deceased left any lineal descendants (children, grandchildren, and further generations):

No lineal descendants survive: the surviving spouse can elect one-half of the estate.
Lineal descendants survive: the surviving spouse can elect one-third.

The elective share stacks on top of exempt property and the family allowance discussed below.²

The Deadline to File

The election must be filed within ten days after the will contest period ends.³ If there is pending litigation over the will or over other questions affecting the spouse’s share, the deadline extends to 90 days after that litigation concludes. Miss the window and the right is gone.

What Counts Against the Share

Missouri does not calculate the elective share off the probate estate alone. The estate for this purpose includes all property the deceased owned at death, reduced by funeral costs, administration expenses, exempt property, family allowance, and enforceable debts. It is then increased by the value of what the surviving spouse already received from the deceased outside probate.⁴

That last piece surprises many people. The following non-probate benefits already received count against the elective share:

Life insurance proceeds paid by premiums the deceased covered
Interests in trusts the deceased created during their lifetime
Pension, retirement plan, or annuity payouts tied to the deceased’s employment (Social Security is excluded)
Joint bank accounts or property where the surviving spouse became sole owner at death

A surviving spouse who was joint owner of a large bank account, for example, may find the whole balance treated as already received.⁴

Exempt Household Property

Certain items belong to the surviving spouse outright, no matter what the will says and out of the reach of estate creditors. The list has no dollar cap and covers the family bible and other books, one passenger vehicle (including a pickup), all family clothing, household electrical appliances, musical instruments, and all kitchen and household furniture, appliances, and utensils.⁵ If there is no surviving spouse, this property passes in equal shares to the deceased’s unmarried minor children.

Transferring a Vehicle Title

The surviving spouse can retitle the vehicle without going through full probate. File a verified application with the Missouri Department of Revenue claiming the vehicle as exempt property under Section 474.250, along with proof of the owner’s death and the current title.⁶

Homestead Allowance

The homestead allowance pays the surviving spouse up to 50% of the estate’s value, capped at $15,000. It is calculated after subtracting exempt property and the family allowance, and it is completely shielded from creditor claims.⁷ The award can consist of money, personal property, real estate, or some combination. If the spouse wants a specific piece of real estate included, that request has to appear in the initial application.

Deadline matters here more than anywhere else. Apply within ten days after the claims filing period ends, or lose the homestead allowance permanently, along with any other homestead rights under Missouri law.⁷ The allowance is offset against whatever the spouse receives as a distributee, but when the allowance exceeds the distributive share, the spouse still keeps the full $15,000.

Family Allowance During Probate

While the estate is being administered, the surviving spouse and any minor children the deceased was supporting are entitled to reasonable maintenance. The court sets the amount based on the applicant’s prior standard of living, the estate’s condition, the applicant’s other income and assets, and the applicant’s expenses.⁸

The family allowance can be a lump sum or periodic installments, and it cannot run longer than one year. Creditors cannot reach it. For a spouse who needs money to cover household expenses while probate drags on, this is often the fastest cash to arrive.⁸

Property Held Jointly

Much of what a couple owns together may skip probate entirely. Missouri treats property held between spouses differently from co-ownership between other people: while grants to non-spouses default to tenancy in common, a grant to a married couple carries survivorship.⁹

Missouri couples traditionally hold real estate as tenants by the entirety, which includes an automatic right of survivorship. When one spouse dies, the other becomes sole owner without any probate involvement. Joint bank accounts and other jointly held financial accounts work the same way. Keep in mind, though, that the value of what passes this way still counts when the elective share is calculated.

Gifts Made to Defeat Spousal Rights

A spouse cannot escape these protections by giving property away during life. Any transfer made in fraud of the surviving spouse’s marital rights can be treated as if it were a bequest in the will and recovered from whoever received it. Any real estate transfer made without the other spouse’s written consent is presumed fraudulent for this purpose.¹⁰

When Misconduct Bars Inheritance

Missouri completely strips a surviving spouse of inheritance rights, homestead allowance, exempt property, and statutory allowances if any of the following was true before the death:

The spouse voluntarily left and continued a relationship with someone else
The spouse abandoned the other without reasonable cause and lived apart for the entire year before death
The spouse continuously lived with another person in an adulterous relationship

The bar is absolute in those situations. It does not apply if the couple voluntarily reconciled and resumed living together before death.¹¹

Small Estate Shortcut

If the total estate after debts and liens is worth $40,000 or less, the surviving spouse can skip formal probate by using a small estate affidavit. The affidavit can be filed once 30 days have passed since the death, as long as no one has applied for formal letters of administration.¹² The filing lists all distributees and debts, requires a bond approved by the probate judge or clerk (which the court can waive), and carries a filing fee. Whoever files the affidavit takes on responsibility for paying the deceased’s debts, funeral expenses, and any state obligations.

Social Security Survivor Benefits

Federal law adds a separate layer on top of anything Missouri provides. A surviving spouse can generally qualify for Social Security survivor benefits if they are at least 60 (or 50 if disabled), were married for at least nine months before the death, and did not remarry before age 60.¹³ A surviving spouse caring for the deceased’s child under 16 can qualify regardless of age or marriage length.

At full retirement age, the surviving spouse can receive up to 100% of the deceased’s benefit. Claiming as early as 60 reduces the payment to 71.5%, with the amount rising the longer the survivor waits to apply.¹⁴
