Okla. Stat. tit. 60, § 60-834: Delivery of statements

A. A seller should deliver either the disclaimer statement or

disclosure statement to the purchaser as soon as practicable, but in

any event it shall be delivered before acceptance of an offer to

purchase.

B. If the disclaimer statement or disclosure statement is

delivered to the purchaser after an offer to purchase has been made,

the offer to purchase shall be accepted only after the purchaser has

acknowledged receipt of the disclaimer statement or disclosure

statement and confirmed the offer to purchase.

C. If the seller becomes aware of a defect after delivery to

the purchaser of either a disclaimer statement or a disclosure

statement, then the seller shall promptly deliver to the purchaser

either a disclosure statement or an amended disclosure statement

which discloses the newly discovered defect. The disclosure

statement or any amendment shall be in writing and shall be signed

and dated by the seller. However, if the required document is

delivered to the purchaser after an offer to purchase has been made,

the offer to purchase shall be accepted only after the purchaser has

acknowledged receipt of the required document and confirmed the

offer to purchase.

D. The purchaser shall acknowledge in writing receipt of the

disclaimer statement or the disclosure statement and any amendment

to the disclosure statement. The purchaser shall sign and date any

acknowledgment. Such acknowledgment should accompany the offer to

purchase the property. If the purchaser confirms the offer to

purchase, such confirmation shall be in writing, shall be signed and

dated by the purchaser and shall be promptly delivered to the

seller.
