Ex-boyfriend's debt on my credit cards, liable?

Hello,
Wanted to knoew if my boyfriend who used my credit card and ran up close to 10,000 in debt in my name is liable if he verbally promised to pay it back. He has also agreed to sign paper showing that the debt on my card is his responsibilty. He has terrible credit and no means of paying off, transferring it, or equity in any physical possessions. I need to know proper steps/recourse to making the debt his and getting removed from my name. Can I sue him, with him signing notarized paper? Do I have recourse to garnish his wages, what means of action should/can I take? Thanks for any advice someone could share with me on this topic!!!

Well you learned never to loan anyone, especially boyfriends money! : - )

Now, when you have such a debt, you need to have it in writing that HE is the owner of those debts or in the absence of written evidence, clear and convincing circumstantial evidence: stuff you would not have purchased, receipts with his signature, etc.

Otherwise, kindly sweet talk him into writing he owes you X amount on the credit card debt. Have him sign it, then take him to court (but don't tell him this) and once judgment is made in your favor, garnish his wages.
