# Summary
An estate plan is only as good as its last update. In Missouri, marriage, divorce, birth, death, major asset changes, a move, and shifts in the law can all make old documents work against you. Knowing which moments call for a fresh look, and doing a routine review every three to five years, is how you keep your intentions intact and protect your people.

# Quotable Q&A
**Q: When should a Missouri resident update their estate plan?**
A: In Missouri, review your plan after any major life change: marriage, divorce, birth of a child or grandchild, death of a beneficiary or named agent, a significant asset change, a move to or from the state, or a change in the law. Even without a triggering event, a formal review every three to five years is wise.

**Q: Does divorce automatically fix my will in Missouri?**
A: Only partially. In Missouri, provisions in favor of a former spouse may be treated as if the spouse predeceased you after a final divorce, but this has limits and does not touch assets outside the will, such as beneficiary designations on IRAs, life insurance, or joint accounts. Updating the entire plan after divorce is the only reliable approach.

# What to check after a shift
An estate plan is a bundle of connected documents, so a change in one place can loosen a knot elsewhere. After any real shift, pull the whole packet. Wills and trusts set who inherits and who serves as guardian, executor, or trustee, and a named successor matters if your first choice dies or cannot serve. Beneficiary designations are the quiet land mines: a bank or insurer reads the form you filed, not your will, so an old 401(k) or policy can drag an ex into an inheritance by accident. Powers of attorney and healthcare papers should name people who still belong in those roles today, and a trust must actually be funded with current accounts and deeds or it sits empty.

# Decision rule
If a major life event happens, marriage, divorce, a new child, a death, a windfall, or a move, then pull out the full plan and update every affected document rather than trusting the defaults to patch it. If nothing major has changed but three to five years have passed, then still run a routine review, including beneficiary forms, because the law and your assets drift over time.
