my father as an independent contractor drilled a well on a newly constructed homeowners property. first well was a bust and then the homeowner gave my father permission to drill a second well. halfway through job completion, landowner told my father to stop drilling. he never paid him for any work or labor completed and he hired another competitor to drill a 3rd well. my father will be filing a Mechanics Lien on the property until payment is made. does he need to file an Intent to File first?
