What makes Missouri different

Missouri's affidavit is a court filing with two extra costs most people don't expect: a bond when the estate is over $15,000 without a will, and newspaper publication of notice to creditors over the same figure.

The clerk issues certified copies of the filed affidavit; that certified copy — not your notarized original — is what the bank wants.
