builder threatening to put a caveat on my property

The question, put plainly: Can a tradesperson put a caveat or lien on my house?

The short answer

Only if the contract gives them an interest in the land, which most trade contracts do not. Lodging a caveat without a proper basis is itself actionable and can attract compensation.

A caveat is a notice recorded against a title that warns the world someone claims an interest in the land. It does not create the interest. To lodge one properly, the person needs a caveatable interest, and simply being owed money for work does not create one.

Where a builder sometimes can

Some building contracts include a charging clause, under which the owner grants the builder a charge over the land as security for money owed. Where a contract contains one and it is enforceable, that can support a caveat. This is exactly why the fine print of a building contract is worth reading before signing, and why a charging clause is worth asking about and often worth negotiating out.

If a caveat appears without basis

  1. Get the contract reviewed to see whether any charging clause exists.
  2. Obtain a copy of the caveat from the land titles office, which states the interest claimed.
  3. Serve a lapsing notice, or apply to the court for removal, depending on your state's procedure.
  4. Note that a person who lodges a caveat without reasonable cause can be liable to compensate you for loss, which matters if it blocks a sale or a refinance.
