Welcome! Thank you for your question.
Unfortunately that is not correct. There are no statutes in Missouri that authorize the next of kin to make medical decisions for the mentally incapacitated adult. Forty-nine states currently permit the next of kin to make medical decisions of incapacitated relatives, the exception being Missouri. Missouri has a Living Will
Statute that requires two witnesses to any signed advanced directive that results in a DNR/DNI code status in the hospital.
The only what that you or any other next of kin have authority to consent to termination of life support is to file a petition to have your parent declared incompetent and a guardian appointed for them. This is done through the probate court in Missouri.
