If you are separated, I would have everything that wasn't in my name, that you want to keep, utilities, credit cards, bank accts, insurances, etc, switched over, just so that what happened with the elec. won't happen with other things. When I separated from my ex husband, he went and had my car ins cancelled, w/o my knowledge, and my car was stolen that very day. What pissed me off, is it was in both our names, and in situations like that, both parties are supposed to sign for it to be cancelled, altered, etc. I was outraged by the ins. company. But I learned a quick lesson, have everything switched into my name or cancelled, whatever necessary. This may give you some peace, judges usually give custody to moms unless they are proven unfit. If he is illegally in the country, that is an issue of it's own. Most dads try for custody to get out of paying child support anyway. My ex tried that this past yr. Of course there was nothing to back it up, it was clear he was trying to get out of back pay he owed, which as usual, I received when he filed taxes. Of course, he still tries to say he isn't behind, and I've received backpay from his past 2 income taxes and will this yr also, be he insists he isn't behind, I mean denial can be bad!One thing I have learned over 8 yrs time also, is I always tried to just let some things go, financially, going back to court, hiring attorneys hasn't always been good, but this year, we were in court from jan until april. and since then when he calls me with his bs and we can't agree, I contact my attorney and I think he realizes that I am doing what is legally right, just like he claims too, also.
