Oklahoma · 16 O.S. §20; 58 O.S. §§3005–3020Oklahoma power of attorney at closing: acknowledgment, recording before the deed and the 7-day acceptance rule

A power of attorney to convey real estate, or to sign or release a mortgage, is executed, acknowledged and recorded like a deed, in the county where the land is; no deed, mortgage or release signed by an attorney-in-fact may be recorded until the power is filed for record in the same office, and recording the deed has no effect until then (16 O.S. §20). A recorded power isn't revoked as to third parties unless the revocation is recorded in the same office (16 O.S. §21). Under Oklahoma's Uniform Power of Attorney Act, a power of attorney is signed by the principal or by someone in the principal's conscious presence at the principal's direction, and the signature is presumed genuine if acknowledged before a notary (58 O.S. §3005); a power executed elsewhere is valid if it complied with that jurisdiction's law, and a photocopy or electronic copy has the same effect as the original (§3006). A person presented with an acknowledged power must accept it or request a certification, translation or opinion of counsel within seven business days, then accept within five business days of receiving it, unless a statutory exception applies (§3020(A)–(B)).
