Collateral Attack on a Judgment Arizona
In Arizona, "a decree in the probate court has all of the conclusiveness inherent in a judgment of a common law court," and, therefore, it may not be collaterally attacked. Cox v. Mackenzie, 70 Ariz. 308, 312, 219 P.2d 1048, 1051 (1950).
A collateral attack on a judgment "is an effort to obtain another and independent judgment which will destroy the effect of the former judgment." Id.
Moreover, unless a judgment is void because the court lacked jurisdiction over the subject matter, over the parties, or to render the particular judgment, the judgment cannot be collaterally attacked even if it is "erroneous or wrong, so that it could be reversed on appeal or set aside on direct attack." Walker v. Davies, 113 Ariz. 233, 235, 550 P.2d 230, 232 (1976) (quoting School Dist. #1 of Navajo County v. Snowflake U.H.S. Dist., 100 Ariz. 389, 391-92, 414 P.2d 985, 987 (1966)).
