My husband received a letter from the sheriff claiming that since he owed about $2000 on a credit card that was later awarded a judgement, can the sheriff come into our home and remove items totalling the $2000 for payment?

Yes, they can.

In many jurisdictions, it is called a sheriffs levy.

Cars, boats, RV's are commonly the type of items they look for, but I suppose it could apply to any property he owns.

What state are you in? It varies from state to state but I would think a wage garnishment and a bank levy would come first especially if it unsecured cc debt
