Which of the following can be classified as a mechanic’s lien?

A mechanic’s lien is a legal claim against a property that arises when a contractor, subcontractor, or supplier has not been paid for work performed or materials supplied in relation to a construction project. This type of lien ensures that unpaid workers have a way to secure the money they are owed by placing a claim on the property itself.

In this context, a claim for unpaid contractors' work is classified as a mechanic’s lien, because it directly involves services or materials provided for the improvement of real property. If a contractor completes work but does not receive payment, they can file a mechanic's lien to protect their right to payment, allowing them to potentially recoup those unpaid amounts if the property is sold.

In contrast, claims for unpaid wages, property tax due, or those related to a court judgment do not fall under the definition of a mechanic's lien. Unpaid wages pertain to employment contracts, property taxes are assessed by governmental entities for local services, and court judgments relate to legal disputes but do not involve improvements to property. Therefore, the only correct classification as a mechanic’s lien in this scenario is the claim for unpaid contractors' work.
