My husband wanted to start a car lot in which they went 50\50 on tools and equipment. The other guy did not do any research and found it was too expensive to start the business. My husband and I decided to start washing cars with equipment and the other guy said he would help. My husband also fixes cars and did a lot of work for that guy and never got paid. Then the guy said he wanted 3000 a month for calling people to see if they wanted car washes and said he don't do labor and won't wash cars. He began to act as if he owned the company and bossing my husband around wanting half of anything he made even fixing cars. We told him this was not working and want to split up equipment and part ways. Now he wants to sue us. Can he do that?
