Hi,
Since CA is a community property state, title does not mean that the house is yours and not his. I'm afraid you will have to do one of two things:
1. Enter divorce mediation and hopefully enter an agreement that he leave at least in the short term.
2. Commence a divorce action and ask for temporary relief in the form of an order compelling him to leave...but that will be difficult because legally he has a right to be there, and no you can't turn off the power. Sorry.
