Starting the 60-day clock for your opponent to file a notice of appeal requires strict compliance with the California Rules of Court, including the service requirements. That means a proof of service. Even actual notice in court is no substitute.
Also, if an unlawful detainer doesn't suit you, have you considered an elder abuse restraining order?
That is what happened in Smith v. Monk (D2d4 Jul. 6, 2021) no. B300975 (nonpub. opn.). Mother settled her unlawful detainer action against daughter, but later decided she still wanted her out. She accomplished this through an elder abuse restraining order.
Daughter's appeal, though unsuccessful, survived mother's challenges to timeliness. Mother failed to trigger the 60-day deadline to appeal because even though the order was personally served on daughter in court, and attached as an exhibit to a later filing, neither of these satisfies California Rules of Court, rule 8.104. The Notice of Entry or file-stamped copy of the order must be separately served and accompanied by a proof of service.
