A mechanic's lien is a legal claim against a property that ensures payment for work performed or materials supplied during construction or renovation. It is typically filed by contractors, subcontractors, or suppliers who have not been paid for their services. This lien gives them a security interest in the property, meaning they can potentially force a sale to recover the owed amount. When a mechanic's lien is filed, it can affect the property owner's ability to sell or refinance the property until the debt is resolved. To remove the lien, the property owner must either pay the debt or contest the lien in court. This process helps protect the rights of those who contribute to the improvement of a property.
