Having been through a California divorce myself, I can just about assure you, that you could be totally screwed. Get a good men’s rights lawyer. They might be able to help you keep some of your assets, so you can support your kids. It might cost you some cash, but it might cost you a whole lot more if you don’t.
My brother went through a divorce in CA a while back and came out OK so it might give some hope...
Seven years married, no kids (phew) but she had him put her on the mortgage one week before she walked and she went after half his retirement.
Took two LONG years but he got away with paying one lump of abt $100K, most of which went to her lawyer...heh....boy, was she po’d!
Definitely money well spent!
