Missouri estate risk overview
This guide explains how estate outcomes work in Missouri when there is no plan. We cover intestacy rules, probate flow, guardianship defaults, and tax exposure in clear, educational language.
Snapshot
Key default outcomes
- Intestacy laws determine who receives assets.
- Probate court oversees the estate and public filings.
- Guardianship for minors is court-appointed if needed.
- State and federal tax rules may apply to larger estates.
What happens without a will
Missouri intestacy gives the surviving spouse the entire estate if there are no descendants; otherwise the spouse receives a statutory share and the rest passes to descendants or other heirs.
- If there are no surviving descendants, the spouse inherits the entire intestate estate.
- If all descendants are also the spouse’s, the spouse receives the first $20,000 plus one-half of the balance.
- If any descendant is not the spouse’s, the spouse receives one-half of the estate.
- Any remaining estate passes to descendants, then to parents and siblings in statutory order.
- An heir must survive the decedent by 120 hours to inherit under intestacy.
Probate process
Missouri permits small-estate administration by affidavit for estates under a statutory cap after a 30-day waiting period.
- The estate value must be $40,000 or less after liens, debts, and encumbrances.
- At least 30 days must pass after death and no letters can be pending.
- A small-estate affidavit is filed with the probate division and may require a bond.
- Small-estate affidavits are filed with the probate division and may require a bond if ordered by the court.
Estate and inheritance tax exposure
Missouri does not impose an estate tax or inheritance tax.
- No Missouri estate tax.
- No Missouri inheritance tax.
- With no state death tax, tax exposure is primarily federal when the estate exceeds the federal exemption.
Guardianship for minors
Missouri gives priority to parents for guardianship of minors; minors 14 or older may nominate a guardian, and parental nominees by will have priority if both parents are deceased.
- Parents are first in priority for appointment unless unfit or waived.
- If no qualified parent is living, a minor over age 14 may nominate a guardian unless contrary to best interests.
- A guardian named by the will of the last surviving parent has priority if both parents are deceased.
- Older minors may nominate a guardian, subject to court approval.
- Parents can nominate a guardian by will or written instrument, subject to court approval.
- Courts rely on best-interest findings when appointing a guardian.
How default rules work in practice
Start with assets, authority, and family structure
- In Missouri, the first practical question is whether an asset is a probate asset. Probate assets are governed by a will or, if there is no valid will, by intestacy rules.
- The next question is who has authority to act. Probate courts generally appoint a personal representative before estate assets can be gathered, creditor claims handled, and remaining property distributed.
- For families with minor children, guardianship is separate from asset transfer. A court can appoint a guardian even when the estate distribution question is still being resolved.
- For taxes, no state estate or inheritance tax is listed. Federal estate tax is separate from state-level exposure and depends on estate value and filing rules.
- Property title and beneficiary designations usually determine whether an asset passes through probate.
Common misconceptions
Assumptions that can change the outcome
- A spouse does not always receive every probate asset automatically.
- A will does not necessarily avoid probate; it usually directs probate assets through the court process.
- Beneficiary designations can override what a will says for accounts that pass by contract.
- Guardianship nominations are important, but courts still make the appointment.
- No state estate tax does not mean every tax or filing question disappears.
What to review before getting advice
A practical checklist for Missouri families
- List assets by title: sole ownership, joint ownership, trust-owned, or beneficiary-designated.
- Confirm beneficiary designations for retirement accounts, life insurance, and payable-on-death accounts.
- Identify minor children, dependents, and any temporary care instructions.
- Check whether real estate, business interests, or family members are located outside the state.
- Review the state-specific tax section before assuming only federal rules matter.
