Okla. Stat. tit. 11, § 11-26-104: Conveyance or devise of lot in trust

A. As used in this section, “lot” means a tract of land as

defined in Section 1 of this act.

B. Any burial lot in any cemetery owned by a municipality, or

by an association incorporated for cemetery purposes under the laws

of Oklahoma, may be conveyed or devised by the owner back to and

held by such company, municipality, or association in perpetual

trust for the purpose of its preservation as a place of burial. The

lot so conveyed shall thereafter remain forever inalienable by act

of the parties, but the right to use the same as a place of burial

of the dead of the family of the owner and his descendants from

generation to generation shall remain, unless the deed of conveyance

in trust shall provide that interments in such lot shall be confined

to the bodies of specified persons, in which case the lot shall be

forever preserved as the burial place of the persons specified in

the deed and shall never be used for any other purpose whatever.

However, no conveyance in trust shall be made without the consent of

the cemetery company or association in whose cemetery the burial lot

is located, or of the governing body or board of cemetery trustees

of the municipality.
