hold on your property, giving your creditor the right to collect a debt out of the proceeds of the sale of your property.
If the City of New Orleans puts a lien on your property, the City will eventually get the right to sell your property without your permission, unless you fight the lien
If a lien is filed against your property by a contractor, you should consult with an attorney. Attorneys may be able to recover fees from the contractor to pay for this challenge.
