Will My Estate Planning Documents Be Recognized in Missouri?

Generally yes. Missouri accepts an out-of-state healthcare directive in practiceRSMo § 404.703(4) via § 404.805.2 (durability of out-of-state instruments); otherwise general comity — § 404.810 does not incorporate § 404.730Verified Oct 15, 2026View source but has no explicit reciprocity statute, so recognition rests on hospital practice and emergency-care doctrine. Missouri has no statute recognizing a health care power of attorney signed in another state. The definition applied to the act treats a power as durable if it was durable under the law of the place where it was signed or of your residence at the time (§ 404.703(4) through § 404.805.2), and providers generally honor an out-of-state document that substantially complies with Missouri law.

Yes. Missouri has its own reciprocity statute for out-of-state powers of attorneyRSMo § 404.730Verified Sep 18, 2026View source: a foreign POA is recognized if it was valid under the law of the place of execution or valid under the principal's domicile law when signed. Missouri has not adopted UPOAA. Per RSMo § 404.730(5): out-of-state durable POAs made under UDPAA or substantially similar law are governed by the designated state's law and, "if durable where executed", may be "carried out and enforced in this state". § 404.730(6): out-of-state resident POAs may authorize Missouri acts under the principal's residence law, place-of-execution law, or Missouri law, "whichever law is most favorable toward authorizing such delegation".

Yes, with one caveat. A trust is a private agreement governed by its own choice-of-law clause, not by any state's filing system, so a trust validly executed in another state has the same force in Missouri for cash, accounts and personal property. The caveat is real estate: Missouri property is deeded into the trust through a Missouri deed before the trust controls it.
