Trust administration in Missouri is typically faster than probate because trusts don't require court supervision. The trustee can shorten the creditor-claim window to 6 months by publishing Missouri's optional notice; otherwise the general 12 months period governs before final distributions are safe. Simple trusts often wrap up in 6-9 months; trusts that hold business interests, real property in multiple states, or that need to file estate tax returns can take longer. See the Missouri trust settlement plan for the full process.
