Which lien is placed on the property by anyone who furnished labor or materials if payment has not been received?

The mechanics lien is a legal claim against a property that arises when a contractor, subcontractor, or supplier has provided labor or materials for improvements on that property but has not received payment for those services. This type of lien is specifically designed to protect the rights of those who contribute to the improvement or construction of a property, ensuring they have a means to seek payment for their work.

When a mechanics lien is filed, it serves as a notice to other potential buyers or lenders that there is an outstanding debt attached to the property, which can complicate the sale or refinancing process. This legal tool allows workers and suppliers to recover their dues from the value added to the property through their labor or materials.

In contrast, a judgment lien is a court-ordered claim against a debtor's property, typically resulting from a civil lawsuit. A license is not a lien but rather a grant of permission to perform certain activities, such as operating a business. A property tax lien is imposed by the government for unpaid property taxes and can lead to foreclosure if unpaid. Mechanics liens are specifically designed for those who provide labor or materials, which is why this answer is the correct choice.
