Does a statute of limitations apply to court fines and fees?
DUI in FL in 1995; moved to IN for my job; still had outstanding fines and fees. Got a letter from an attorney yesterday demanding payment of $4600. Do I pay it?
Absolutely you pay it. The statute of limitations has nothing to do with this.
The statute of limitations deals with claims: a person believing that another legally owes the person money, must file a lawsuit to try to enforce that, within the time limit. The lawsuit then determines whether or not the money is actually owed, and issues a judgment, one way or the other.
The court can go beyond the limitations period, sometimes just with the court proceedings themselves, before reaching that judgment. The statute only deals with when a lawsuit can be filed.
No lawsuit needs to be filed, as far as your DUI fines and fees. They have already been "reduced to judgment." The statute of limitations has nothing to do with this. Florida might well file a lawsuit against you in Indiana, but only to allow their judgment to be formally granted full faith and credit so your assets and income in Indiana can be attached.
