Okla. Stat. tit. 21, § 21-1158b: Funeral service agreements - Instructions

Any person signing a funeral service agreement, cremation

authorization form, or any other authorization for disposition shall

be deemed to warrant the truthfulness of any facts set forth

therein, including the identity of the decedent whose remains are to

be buried, cremated, or otherwise disposed of, and the authority of

the person to order such disposition. A funeral establishment shall

have the right to rely on such funeral service contract or

authorization and shall have the authority to carry out the

instructions of the person or persons who the funeral director

reasonably believes holds the right of disposition. The funeral

director shall have no responsibility to contact or to independently

investigate the existence of any next of kin or relative of the

decedent. If there is more than one person in a class who are equal

in priority and the funeral director has no knowledge of any

objection by other members of such class, the funeral director shall

be entitled to rely on and act according to the instructions of the

first person in the class to make funeral and disposition

arrangements; provided that no other person in such class provides

written notice of objections to the funeral director.
