Elmer Cordova and Dorothy Cordova, Husband and Wife, Appellants (defendants) v. Antonia Gosar, Appellee (plaintiff)

Summary

The Wyoming Supreme Court affirmed summary judgment invalidating the deed's inclusion of the property occupied by Gosar. The court held that evidence of mutual mistake may be considered notwithstanding the parol-evidence rule, but Cordova's evidence of a contemporaneous oral occupancy agreement was inadmissible because it would add to the unambiguous written agreement. The court also upheld the denial of judicial disqualification and concluded that the conflicting affidavits did not justify disregarding the parol-evidence ruling.
