# Summary

The firm's will-or-trust guide walks Missourians through eight factors that point toward a will, a trust, or both: marital status, children, estate size, privacy, multi-state property, incapacity, speed of distribution, and cost priority. A will is simpler and cheaper to create but goes through public probate and only takes effect at death; a revocable living trust costs more upfront but avoids probate, stays private, and lets a successor trustee manage assets during incapacity. Many families need both.

# Quotable Q&A

**Q: What is the core difference between a will and a trust in Missouri?**
A: In Missouri a will is required and public: it goes through probate, which typically takes six to eighteen months, and only takes effect at death. A properly funded revocable living trust avoids probate entirely for funded assets, stays private because it is not filed with any court, and lets a successor trustee manage assets seamlessly if you become incapacitated. Probate costs in Missouri typically run 3 to 5 percent of estate value.

**Q: If I have a trust, do I still need a will in Missouri?**
A: Yes. A trust cannot name guardians for minor children, so a will is still required for that, and a pour-over will catches anything not titled into the trust. The trust handles private, fast, controlled transfer; the will handles guardianship and the backstop.

**Q: Which factors push a Missouri plan toward a trust?**
A: The guide weights several factors toward a trust: an estate over $100,000 where probate costs of 3 to 5 percent become significant, a strong privacy preference, real property in more than one state (which avoids ancillary probate), a priority on seamless incapacity management, and a desire for quick distribution. A small estate under $40,000 (eligible for a small-estate affidavit under RSMo 473.097) and a focus on low upfront cost lean toward a will.

# The will-versus-trust comparison

The page's comparison table contrasts the two on probate (required and public for a will, avoided for a funded trust), privacy (public record versus private), incapacity (no protection under a will versus successor-trustee management), cost (lower upfront for a will, lower at death for a trust), multi-state property (ancillary probate versus none), guardianship (only a will can name guardians), and maintenance (a will is simple to update; a trust must be kept funded). Missouri probate is governed by Chapter 473 and trusts by the Missouri Uniform Trust Code, Chapter 456.

# Decision rule

If privacy, incapacity protection, speed, multi-state property, or a larger estate matter, lean toward a funded revocable living trust paired with a pour-over will; if the estate is small and minimizing upfront cost is the priority, a will may serve current needs, revisited as circumstances change. When factors point both ways, the firm's guidance is to consult an attorney.
