How hard is it to enforce a judgment in another state?

It is typically no more difficult to enforce a judgment in another state than it is in the state where it was originally entered. Thanks to the Uniform Enforcement of Foreign Judgments Act. which has been adopted in nearly every state, the process of "domesticating" a judgment from one state to another is fairly easy, and involves little cost. Once domesticated in the new state, the judgment creditor can avail itself of any legal remedy in that state.

Some states are easier than others to collect judgments in; some states, like North Carolina for example, currently do not allow the judgment creditor to garnish the wages of the debtor to collect on the judgment. Many other states, however, do allow this. So it will largely depend on the state where the debtor has moved to.

Other than the logistics of coordinating legal efforts from another state, the process is no more difficult than enforcing a judgment in one's own state.
