Okla. Stat. tit. 30, § 30-4-502: Two or more guardians

A. If there are two guardians, the act of one alone shall be

effectual:

1. If a coguardian is laboring under any legal disability from

serving, said coguardian in such case shall be relieved from

official liability; provided however, proper finding and valid order

of the district court having jurisdiction therein is first obtained;

or

2. If a coguardian has given the other coguardian authority in

writing to act for both.

B. If there are more than two guardians, the act of a majority

of them is valid, however, any guardian may authorize his or her

coguardians to act on that guardian's behalf by giving the other

coguardian authority in writing to do so.
