I did a lot of research and hired a lawyer -- there was just enough uncertainty about my wife and I's situation that I didn't want to take a chance. The lawyer I went with has a "money-back guarantee", which really just means they won't accept a case unless they're certain it'll be successful. They've been really helpful along the way and took care of the majority of the work, giving us great peace of mind... at a price, of course! I'd say if you can afford it and it's worth it to you, you should hire a consultant or lawyer. Just do your research first!
