A. The venue for a guardianship proceeding is in:

1. The district court of the county where the minor or the

incapacitated or partially incapacitated person resides;

2. The district court of the county where the proposed guardian

resides if the proposed guardian is a member of the minor's or

Oklahoma Statutes - Title 30. Guardian and Ward Page 14

a nonresident minor or incapacitated person shall be in a county

where the nonresident has property.

B. If a proceeding pursuant to the provisions of the Oklahoma

Guardianship and Conservatorship Act could be maintained in more

than one place in this state, the court in which the proceeding is

first commenced has the exclusive right to exercise jurisdiction

over the proceeding and proceed with the action. A court shall not

exercise jurisdiction over a proceeding for guardianship of a minor

pursuant to this title if, at the time the petition for guardianship

is filed, another court of this state is exercising jurisdiction

pursuant to Section 1-4-101 of Title 10A of the Oklahoma Statutes,

unless after notice to the parties in the deprived action, the

written consent of such court is obtained and filed in the

guardianship proceeding.

1. If proceedings concerning the same estate, minor, alleged

incapacitated or partially incapacitated person, or ward are

commenced in more than one court of this state, the court in which a

proceeding was first commenced shall continue to hear the matter and

determine venue. If the court where the proceeding was first filed

determines that venue is properly in another court, it shall

transfer the proceeding to the other court.

2. If the court finds that in the interest of justice a

proceeding should be conducted in another court of this state, the

court may transfer the proceeding to the other court.

C. If both guardianship and conservatorship proceedings as to

the same person are commenced or pending in the same court, the

proceedings may be consolidated.
