# Summary
A second marriage layers new obligations on top of old ones, and Missouri's default rules do not account for that. If you die without a plan, the state splits your estate by formula, often sending property where you never intended. Clear documents let you provide for a new spouse and still protect children from a prior relationship.

# Quotable Q&A
**Q: If I remarry in Missouri and die without a will, who inherits?**
A: In Missouri, if you have children who are not also your current spouse's children, the surviving spouse takes the first $20,000 plus half of the rest, and your children take the remainder. That formula can force a surviving spouse to negotiate with stepchildren over a house or farm. With a will or trust you decide instead of letting the state's template decide for you.

**Q: Can I leave everything to my children and cut out my new spouse?**
A: Not fully. Missouri gives a surviving spouse an elective share, a portion of the estate based on the length of the marriage, regardless of what your will says. Good planning works with that right rather than against it.

# Tools That Fit a Second Marriage
The firm points to several tools built for remarriage rather than a fill-in-the-blank will. A will drafted for your names and property can split assets in precise terms, name a steady executor, and define which children you mean, since step, biological, and adopted each carry different consequences. A revocable living trust can let a surviving spouse take income or a home for life while preserving the principal for your children, and it keeps the matter out of probate. A life estate or a right-to-occupy clause can hand a spouse the family home for life, then pass it to your children, as long as it spells out who pays taxes, insurance, and repairs. Pre- and post-nuptial agreements are allowed in Missouri and can set expectations and waive certain property rights when both sides disclose fully.

Beneficiary forms are the hidden danger. Life insurance, retirement accounts, and POD or TOD bank forms pay out to whoever is named, skipping the will entirely. A missed update after divorce or remarriage can send money to the wrong person, so these designations must fit the whole plan.

# Decision rule
If you have children from a prior relationship and want a new spouse cared for without disinheriting those children, then use a trust with a life-income or right-to-occupy structure rather than relying on a simple will. If you have updated beneficiary forms recently, then confirm they still match your current plan before assuming the will controls.
