Okla. Stat. tit. 82, § 82-544: Notice of hearing on petition

Immediately after the filing of such petition, the clerk of the

district court, with whom such petition is filed, or to whom it has

been assigned, shall cause notice by publication, to be made of the

pendency of the petition and of the time and place of the hearing

thereon, and said notice as provided herein shall be given in each

county affected by the district, and the time of hearing shall be

not less than sixty (60) days from the date of the first

court in which the petition was filed, or to whom it was assigned,

shall thereafter, for all purposes of this act, except as

hereinafter otherwise provided, maintain and have original and

exclusive jurisdiction coextensive with the boundaries and limits of

said district, and of lands and other property to be included in

said district, or affected by said district, without regard to the

usual or other limits of its jurisdiction and shall convene at the

convenient county seat.
