What is the test for establishing that a description in a judgment is certain and specific?

'Applied to judgments, the rule is that the description in a judgment affecting real property should be certain and specific, and that an impossible, wrong, or uncertain description, or no description at all, renders the judgment erroneous and void.'

(Newport v. Hatton, 195 Cal. 132, 156, 231 P. 987, 996.)

'The object of the action is to finally settle and determine, as between the parties, all conflicting claims to the property in controversy, and to decree to each such interest or estate therein as he may be entitled to.'

(Peterson v. Gibbs, 147 Cal. 1, 5, 81 P. 121, 123.)
