How can we put a lean on an x husband who owes money to the IRS. But the IRS is coming after me. To the tune of 20,000 dollars. He owns a construction company. Is there any way I can put a lean on him so that he has to pay 1/2 the money back. In our divorce decree it makes us responsible for 1/2 the debt. However, I am paying back the entire amount. They don't seem to want to go after him at all.
