I have a sub that is very annoying and pesky. I cut off work to this sub Jan 10, 2013. With my company I've made it a policy to rendered final payment 90-120 from last job. I do this to make sure my clients pay out and don't cut my invoices or whatever. Needless to say this idiot has called my client and complained and threaten to lien properties. My contract has a waiver of lien rights and a clause that late work will be penalized to the tune of 50 percent for 1 day late then 100 percent for 2 days or more late. From her invoices their is $1100 dollars discounted off for late work according to the contract. Problem is she never fully signed the contract but verbally agreed to it because at the time her husband was having surgery and we both just forgot about it. What should I do?? Love to hear your thoughts.
