Wyo. Stat. § 2-9-203 (2026)

hearing; determination and decree.

     (a) Upon hearing, if it appears to the court that more
than two (2) years have elapsed since the death of the deceased,
that he died seized of an interest in lands in this state or
that he died intestate having entered government lands and not
having received a patent therefor, and there has been no
previous record judicial determination of the decedent's heirs
or the right of descent of the real property interest, the court
shall determine the date of the decedent's death, who were the
heirs of the deceased upon the date of death, their degree of
kinship, the right of descent of the real property or interest
therein of which the deceased died seized or on which he had
made an entry but had not yet received a patent therefor and the
distribution each heir is entitled to receive from the known and
unknown real property interests of the decedent based on the
determination of the right of descent, and shall make and enter
its decree accordingly.

     (b) The findings of the court relating to a decedent's
date of death, intestacy, heirs, degree of kinship and right of
descent shall apply to any other real property in this state
subsequently discovered in which the decedent had a property
interest at the time of his death as identified by an affidavit
recorded pursuant to W.S. 34-11-101, provided that:

          (i) A copy of the judicial determination of the
decedent's heirs or right of descent shall be included with an
affidavit filed under W.S. 34-11-101 for the subsequently
discovered property;

          (ii) No other recorded judicial determination has
been made relating to the right of descent for that property.
