Okla. Stat. tit. 58, § 58-710

At or before the hearing of petitions and contests for the

probate of wills; for letters testamentary or of the administration;

for sales of real estate and confirmation thereof; settlements,

partitions and distributions of estates; and all other proceedings

where all the parties interested in the estate are required to be

notified thereof, the court may, in its discretion, appoint some

competent attorney-at-law to represent in all such proceedings the

devisees, legatees, heirs, or creditors of the decedent, who are

minors and have no general guardian in the county, or who are

nonresidents of the state, and those interested, who, though they

are neither such minors or nonresidents, are unrepresented. The

order must specify the names of the parties for whom the attorney is

appointed, who is thereby authorized to represent such parties in

all such proceedings had subsequent to his appointment. The

attorney may receive a fee to be fixed by the court for his

services, which must be paid out of the funds of the estate as

necessary expenses of administration, and upon distribution may be

charged to the party represented by the attorney. If for any cause

it becomes necessary, the district court may substitute another

attorney for the one first appointed, in which case the fee must be

proportionately divided. The nonappointment of an attorney will not

affect the validity of any of the proceedings.
