Tell him NOT to leave that house no matter what.
Yes he has to give his financials for the last three years and so does she...
Unfortunately, I'll tell you this....he really really needs legal assistance....Go to the court house or look on line for a "Family Law Office" in or near your town. There is not a lot of help out there and what is out there sucks if you ask me and the legal system is skewed to those who have lawyers and those who don't......and I'm a woman. I was in court last week and represented myself...was not allowed to speak only his lawyer and was told to get a lawyer by the judge, already had a lawyer that I fired because she did nothing and it cost my parents $8000.00 which I owe.....judge admitted to not reading the original file and briefly skimming the Conference Brief..............hahahahahah what a joke. I spent weeks of sleepless nights and typing and printing and filing papers with the court that no one read. GREAT !!!!!! I do not qualify for Legal aid because I make $444 a month on EI and his nominal support of $600. dollars...nice eh!!! Married 22 years...2 children..he has them and I left the house but if I'd have claimed abuse I'd be better off. I still have no separation agreement after all this....
I found a lot of useful information on these sites but you have to read & read & read.....
