My husband moved out 5 months ago, leaving me with a huge mortgage and all of the bills. He wants $20,000. His ''fair share''. I thought I was only obligated to pay him 1/2 of the home's equity. also he said if I don't pay him, he'll put the home up for sale. Can he do that if it is in both of our names? I've been making the mortgage payment (barlely) on my own since he left. Please help me!! He has retained a lawyer. I can not afford one right now, obviously!! Please, I need your help desperately. I have 2 children. One of them going to college in the fall, so finances are critical right now!
