You need to be clear on a few things. First of all, a judgement must be obtained before the applicable statute of limitations has run. If it a suit is timely filed and a judgement is granted then the statute of limitations no longer applies. The judgement is good until it expires or is renewed. The law on this varies from state-to-state, however typically, a judgment civil judgement is good for anywhere from 3-10 years. Additionally, in some states judgements can be renewed 1 or more times.Note: Once a judgment does expire (including any all renewals0 it is no longer enforceable.
