Okla. Stat. tit. 12, § 12-1509: Duty of commissioners - Report - Notice of time limit for

filing exception or election.

A. The commissioners shall make partition of the property among

the parties according to their respective interests, if such

partition can be made without manifest injury. But if such

partition cannot be made, the commissioners shall make a valuation

and appraisement of the property. They shall make a report of their

proceedings to the court, forthwith. For the purpose of this

section the term "party" shall mean one who has been adjudged to own

an undivided interest in the property involved in the action.

B. Within ten (10) days after the report of commissioners is

filed with the court clerk, the attorney for the plaintiff shall

forward by certified mail to the attorney of record for every other

party in the case and to each party not represented by an attorney,

a copy of the commissioners' report and a notice stating that the

time limit for filing an exception or an election to take the

property at the appraisement, if partition cannot be made, is not

later than twenty (20) days from the date the report was filed.

Before the expiration of the said twenty (20) days, the court may

fix a different and longer period for the filing of an election.

The mailing of notice as required herein shall be certified by

affidavit to be filed, attached to the original notice. If a party

has been served by publication, the notice of said time limit shall

be published in one issue of a newspaper qualified to publish legal

notices, at least ten (10) days prior to the expiration of the date

to file exception or election.

C. The time limit for filing an exception or an election to

take property at appraisement, as prescribed in subsection B of this

section, shall be calculated from the date the report of the

commissioners is filed in the case. On failure of the attorney for

plaintiff to give notice within the time prescribed in subsection B

of this section, the court, on application of any party, may extend

the time for filing an exception or an election for the period not

to exceed twenty (20) days from the date the application is heard.
