Hi, I need advice on a scenario. If there is a dispute over the satisfactory of a job done by a subcontractor, how is it resolved? I know a subcontractor who did lawnmowing work for a contractor in Montana. The contractor is several weeks late on paying the subcontractor and is now claiming the job was not done well, as well as claiming subcontractor will owe him money for the cost of a company he hired to fix the job. There was no prior complaint of unsatisfactory work until The late payment was brought up. There are also witnesses, including the clients, to vouch for the quality of the job done. The only person claiming poor quality of the lawn mowing jobs is the contractor himself who is refusing to pay. What do you recommend?
