What exactly can my ex do to get me to pay the owed taxes? He claims I owe more due to capital gains taxes. I told him via phone I'd give him money when I can but I have no intention on really paying "my share" when he owes me more than the owed IRS amount. The divorce decree says payment to IRS should be made equally and the same with a refund but what exactly can he do to get the money from me if anything? Thanks.
