Generally, Colorado’s mechanic’s lien statute limits the amount of a lien to the value of the materials, labor, or services provided. The amount of a lien may also extend to the full contract price, and may include interest. Thus, if you fully performed your side of the contract, you should be entitled to the entire contract price. The law is less clear on the subject of whether lien amounts may include additional damages flowing from the owner’s breach. If the additional costs you now bear relate to materials, labor and services provided to the owner, a good faith argument may exist that such amounts are properly included in the lien amount. Because a lien that is knowingly overstated is invalid, however, and because a party that records an excessive lien may be liable to the owner for the owner’s attorney fees and costs, great care should be taken to assert a lien only for the amount actually due.
