Setting aside judgment by parties under disability, absent, or not notified; time limitations; conclusiveness of judgment; effect of proceedings on bona fide purchaser
When proceedings have been instituted and judgment of the partition has been rendered according to the regulations prescribed in this part and if any one of the parties in interest is a minor or a mentally ill or retarded person who has no guardian, or is absent from the state during such
proceeding, or has not been notified thereof, such minor or mentally ill or retarded person may, within 12 months after coming of age, after restoration of mind, or after having a guardian appointed, as the case may be, and such absent or unnotified party may, at any time within 12 months after rendition of the judgment, move the court to set aside the judgment on any of the grounds upon which a party notified and free from disabilities might have resisted the judgment upon the hearing as authorized by Code Section
