I live in Michigan. A contractor filed a lien on my home residence. He is trying to charge us $1800 for a door that only cost $600 so we withheld his final payment of $1100 for labor. He has since filed a mechanics lien on our home through your website levelset. He is not licensed and it expired in May of 2019. In Michigan, you must be licensed in order to file a mechanics lien on a residential property. How was he able to do this through the levelset website.
I would add that there are several other things to consider. For example, if you agreed to the price of $1800 for an installed door, and he installed the door, it makes no difference how much the door cost. You have a contract for $1800. Also, consider that all persons are not required to be licensed. Commercial construction contractors, for example, need no license. Finally, consider that the cost of hiring an attorney and fighting this claim, in court, will likely greatly exceed the $1200 still being claimed by this contractor. The chances are very good that you are better off settling this claim.
