I asked a guy to help me out in a job he showed up late we went to job the equipment he brought didn’t work so I asked him to go to Lowe’s get supply’s to finish job. He left at 815 am we arrived at 8 am he didn’t return to job until 230 with another person not approved to work for me and showed him how to apply tile to the wall he applied 3 pcs and then left again at 245 pm. He cane back at 345 when we were finished to pick up his equipment He paid 160 dollars for supplies I paid him 220 in return for picking up supply’s and buying the items himself even tho I told him user my account so he didn’t have to pay for it himself and the left over supply’s he returned to 60 dollars so he Made 120 dollars for picking up supply’s for me and working 5 mins. He then demanded an additional 400 dollars stating we had a verbal agreement on splitting the shin 50 50 and we did not he is threatening to file a Lein on my clients home Can he do that or can I fight it if he does ? What are my legal rights if he does this he was never an employee he would have been a self employed sole proprietor never on my payroll either.
