As has been said, wait on Spaz for the legal stuff, but here are a few things for you that aren’t legal. First off, unless and until you are given official papers from the Canadian government pertaining to citizenship, I would just ignore. If he DID forge your name, the papers are invalid and the U.S. Government will back your claim any day. Same for him suing for custody. There has to be a compelling reason, not just BS he makes up. I sincerely doubt that any U.S. judge is going to just let him take the kids and make them citizens of a foreign country just because he wants to. Next off, he has absolutely no business telling your kids that he’s going to be doing anything of the sort. THAT, if you can prove it, is him trying to alienate the kids from you. Judges don’t like that very much either. If you are sincerely concerned that this jackwagon ex of yours is doing some kind of illegal paper shuffle with your kids citizenship, do some on-line research and ASK the Canadian government about it. Believe it or not, with the exception of a few folks I’ve met from Quebec, Canadians seem to be pretty decent and up-front folks. So it couldn’t hurt, ya know? Even if he DOES somehow manage to get the Canadians to grant citizenship to your minor children, you will still have U.S. law on your side. And it’s not like Canada can just send a couple of Mounties into the U.S. to take your kids from you, ok?Wait on Spaz, but I think he’s mostly hot air.Zen Hugs
