I am a GC and hired a sub GC to remodel a bathroom, some plumbing and a vanity replacement for a second bathroom also exterior painting. The client was extremely difficult to work with and would make so many unreasonable demands that no workers would wanna go back and continue the work. We had to issue him a credit for not fulfilling the last part of the contract (vanity replacement-2nd bathroom). Now he is refusing to pay and keeps claiming that the job in not complete and doesn't want us back at his property. He owes about $2936 which after giving him a credit of $1000 will owe about $1936. Everything is in working and perfect condition after the remodel and he is just looking for an excuse no to pay and had also filled with CSLB. Do I still have a valid case to file a mechanis lien even though had deducted $1000 with his claim of non completion? Also who's name do I use in order to file him as a person that we had a contract with (the son of the owner whom lives at the property) or the actual owners' name? Thanks for your help in advance!
