Melvin S. Goldsman said Pamela Bach notified his office Wednesday that she plans to move out of the San Fernando Valley home by Oct. 1.
The agreement came two days after Bach pleaded with Superior Court Judge Mark A. Juhas to delay the trial concerning her request for additional financial support from Hasselhoff.
She told the judge her lawyers needed more time to review Hasselhoff's financial documents.
Juhas said he could not find legal grounds to grant the request to delay the trial beyond Oct. 1, but agreed to do so if she left the home so Hasselhoff could move back in with the couple's two daughters.
Hasselhoff has sole legal and primary physical custody of the girls.
Goldsman had opposed delaying the trial, which he said has already cost Hasselhoff $1 million in attorneys' fees for himself and Bach.
Hasselhoff and Bach were married in December 1989. He filed for divorce in January 2006 and their divorce became final that August.
