In order to have a lien removed from your property, you need to determine first of all if the outstanding debt is legitimately your responsibility. Mistakes can happen. Sometimes you have hired a contractor to complete a job and that contractor has not paid a subcontractor who did part of the work. Some subcontractors file a lien as a matter of course, and they will then remove the lien when they have been paid. It is very important to be sure that all of the subcontractors have been paid before you pay the final bill to the contractor. If the contractor never does pay the subcontractor, the subcontractor can come to you for their payment even if you already paid the contractor for the work done by the subcontractor.
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.
