If you are a contractor or a homeowner working with a contractor, it’s important to know about builders’ liens. 

This page provides general legal information about builders' liens under Nova Scotia's Builders’ Lien Act, including: 

  • what liens are and
  • how to register, enforce or dispute a lien.

A lien is a type of security. Anyone who performs work on or supplies materials to someone else’s land can register a builders’ lien against that land as security for getting paid. Contractors can register liens on various construction projects, including building and renovating homes.

Once registered at the appropriate Land Registration Office, a builder’s lien affects the owner’s interest in the property and can interfere with selling or mortgaging the property.

Each province has builders’ lien legislation that gives this remedy to suppliers and contractors, and each law is slightly different. This page only discusses Nova Scotia’s law, so if you have worked on a property outside Nova Scotia, you must look at the legislation in that province,  territory or other place.

This information does not replace legal advice from a lawyer. Liens are very technical and complicated. We recommend hiring a lawyer if you are considering registering a lien or if a contract or sub-contractor has registered a lien against your property.
