What is the test for making a finding of fact in a motion for community property?

Findings of fact are required only upon trial of a question of fact. (Code Civ.Proc. 632; Robinson v. Robinson (1962) 208 Cal.App.2d 213, 217, 25 Cal.Rptr. 143.) This section assumes that evidence will be introduced on issues raised by the pleadings. However, where the issue is withdrawn and no such evidence is introduced, no finding is necessary. (Robinson v. Robinson, Supra, at p. 217, 25 Cal.Rptr. 143.) The stipulation in question amounted to a withdrawal (Robinson v. Robinson, Supra, at p. 217, 25 Cal.Rptr. 143,) of the community property issue, thus relieving the court of the duty of making findings.
