and by publication in newspaper.

When the petition mentioned in 10 O.S. 1971, Section 92, is

filed the court shall fix a day for the hearing thereof, which day

shall be not less than fifteen (15) nor more than thirty (30) days

from the date of the filing of the petition. Notice of the hearing

of the petition shall be sent by certified mail, return receipt

requested, delivery restricted to addressee only, to the parents of

the minor, if living, to the guardian of the minor, if one has been

appointed, or to the person who has custody of the minor if such

person is other than parent or guardian of the minor, and if both of

the minor's parents are dead, the court may order that notice be

sent by certified mail, return receipt requested, delivery

restricted to addressee only, to other relatives of the minor;

provided, however, that no notice shall be sent to a person who

endorses on the petition that notice of the day of the hearing is

waived. Notice of the hearing shall be given by publication in some

newspaper printed in the county where such petition is filed, and if

there be none, then in some legal newspaper having a general

circulation in the county one time, at least ten (10) days prior to

the day set for the hearing of the said petition. Before the court

may enter an order conferring majority rights in the hearing

provided for herein, proof must be presented to the court at said

hearing that notice was given to all persons entitled thereto as

provided herein.
