We did some plumbing work and appliance removal for a project that our main realtor group told us was ours, so we wrote up a contract and sent it off to the group and the owner. They wanted to get the ball rolling immediately so that they could flip the property and put it on the market as soon as possible. We have a good relationship with the group, so we did some work without the contract being signed, and it turned out that the owner decided to go with another contracting company to do the renovation. We invoiced him for the work that was done, but he only wants to pay a portion of it. My boss wants to put a lien on the property until we are paid in full for our work, but I’m wondering if it is even possible without ever having a signed contract in hand? Hope to hear back from you soon! Thank you very much for your time.
