I'm a property owner. A general contractor did some work on my property. He didn't finish the project but claims I owe him money. According to the contract the final two final payments that haven't been payed should be payed after he finishing painting and electrical work and the final payment after final walk through. The painting and the electrical work is not finished and a final walk through never took place. Can he file a mechanics lien? Can he file a civil lawsuit to get compensation? If so, what is the statute of limitations on a civil lawsuit in this case?
