Okla. Stat. tit. 58, § 58-251: Powers and duties of executors and administrators

The executor or administrator must take into his possession all

the estate of the decedent, real and personal, except the homestead

and personal property not assets, and collect all debts due to the

decedent or to the estate. For the purpose of bringing suits to

quiet title or for partition of such estate, the possession of the

executors or administrators, is the possession of the heirs or

devisees; such possession by the heirs or devisees is subject,

however, to the possession of the executor or administrator, for the

purpose of administration, as provided in this chapter.
