Unlike child support, spousal support is often very difficult (if not impossible) to modify after the divorce is final, so getting it right the first time is a must!
File, serve her, and maybe even file for annulment if that is allowable in California under the circumstances of her spending most of the marriage in prison. Alimony is highly unlikely under the circumstances but you need to make sure he stays on top of the sitaution, not allowing any hearings to take place without his participation (he may be allowed to appear by phone depending upon tghe court rules, but he needs to be up to speed on the court rules to make that happen... some require a request for telephonic appearance ahead of time... some don't allow it at all, some require you initiate the phone call, others will do it, themselves. BUT it's always better if he shows up in person. It's harder for a judge to do the wrong thing to someone who is sitting in front of them in court than if they're two states away on the telephone. And if she gets alimony, there's a whole lot of money potentially at stake, enough to justify the time and effort to travel to court for the bigger hearings.
But first, he needs to contact a lawyer about whether or not an annulment is acceptable in California under these circumstances and start the process. (why annulment? Because it woudl be clear that she couldn't get a dime of his property or a dime of alimony out of him if an annulment was the way it went)
