A Tradition Of Solving Legal Issues

Can you disinherit a family member under Missouri law?

On Behalf of | Nov 19, 2025 | Estate Planning

When planning your estate, you might want to leave certain people out of your will. While this choice is personal, Missouri law sets limits on how and when you can disinherit family members. Understanding these rules helps ensure your wishes are clear and legally enforceable.

Disinheriting a spouse in Missouri

In Missouri, you cannot completely disinherit your spouse through a will. State law gives surviving spouses an “elective share” — a right to claim a portion of your estate, even if your will says otherwise. This rule exists to prevent one spouse from being left without financial support. If your spouse chooses this elective share, they may receive up to one-third of your estate, depending on the situation.

Disinheriting children or other relatives

Unlike spouses, adult children and other relatives do not have the same guaranteed rights. You can disinherit them if you make your intentions clear in your will. Simply leaving them out might lead to disputes later, so it’s good to state directly that you are intentionally omitting that person. Missouri law does not allow parents to disinherit minor children when it comes to child support or guardianship obligations.

Avoiding confusion and will contests

Vague or unclear wording in your will can invite challenges from family members who feel wronged. To help avoid this, use precise language that reflects your intent. You can also use tools like trusts to further control how your assets are distributed. Clear documentation and proper witnesses help ensure your will stands up in probate court.

Protecting your final wishes

While disinheriting a family member is a sensitive decision, it’s important to handle it carefully. Missouri law allows you to make that choice, but only when it’s clearly stated and properly executed. Reviewing your will regularly ensures that your estate plan still reflects your current relationships and intentions.
