I terminated a subcontractor for substandard work and also changing the construction plan without authorization from the permitting agency. The project was not anywhere near completion either. The subcontractor was paid approximately one half of their quoted labor before termination. Once terminated, they demanded full compensation for the project and another project they quoted but never got approval from the homeowner. Now they have sent a notice demanding payment to the client or will they will file a lien against them. This subcontractor had no signed contract for either project. What recourse does the homeowner have against a supposed lien?
Unsure if you are the GC or the Homeowner, but the recourse depends on the lien they file. If it claims that entire amount, it may be considered fraud. They will also need to file it timely with all the proper notice provided as well. The must also timely file suit to enforce the lien. As such, there are many ways to attack the validity of the lien. I would recommend ensuring that you handled payment fairly and frankly waiting to see if they actually comply with all the statutory obligations of filing a lien and enforcing a lien properly.
I would put that all in a letter. I would also consider a cease and desist if they are spreading inaccurate information about the situation.
