§ 2-2-101 — Exclusive jurisdiction conferred on district courts

The district courts of the state have exclusive original
jurisdiction of all matters relating to the probate and contest
of wills and testaments, the granting of letters testamentary
and of administration, and the settlement and distribution of
decedents' estates. The court granting the letters has exclusive
jurisdiction of all matters touching the settlement and
distribution of the estates for which letters have been granted.
The jurisdiction over subject matter of the district court
sitting in probate, sometimes referred to in this Title 2 as the
"probate court", is coextensive with the jurisdiction over
subject matter of the district court in any civil action. A
decree of distribution entered by the district court in probate,
pursuant to W.S. 2-7-807 or 2-7-813, shall be a final
determination of title as to assets described therein, as to all
distributees served with notice, or who have waived notice, of
the hearing provided for in W.S. 2-7-807 or 2-7-811, as the case
may be. As to all other parties, an action may be brought and
maintained at any time prior to the entry of final decree of
distribution under W.S. 2-7-813, by or against the personal
representative in the district court, sitting in probate,
seeking any legal or equitable remedy as to any interest in
property, real or personal, in which the estate asserts or
claims any interest. In addition, all causes cognizable in the
district court in any civil action may be brought and
maintained, at any time prior to the entry of final decree of
distribution under W.S. 2-7-813, by or against a personal
representative in the district court sitting in probate which
granted the letters to the personal representative.
