Are you asking because you are in the escrow time period to sell your home? If so, you should work with the title agent, whether it is a title company or an attorney to plan your actions to meet the contract deadlines. Sometimes, liens are removed at closing as an item on the HUD statement.
If your home is not currently under contract to be sold, then you should go to the court house to obtain a copy of the lien or in some cases you can call and ask that a copy be mailed to you. If you agree that you indeed do owe this amount, then you should try to work out a payment plan. If you do not agree that the charges are legitimate, you should work with your legal advisor. There are so many variations and reasons that you may disagree with the amount or the veracity of the charges being imposed, you will very likely need legal advise.
If your home is currently listed for sale, time is of the essence in resolving the lien on your property. The home cannot be sold without having the lien removed in some manner. Best wishes.
