Hello, I have been made aware to get lien waivers from GC after each invoice paid- I am now near end of job. I am located in California this is for commercial site I’m a tenant. I am about to request those waivers however I also paid upfront 35k retainer to him. That retainer has been untouched and sitting there until end of project as part of final installment. Do I need to get a waiver for that as well? How would that work? Or will it just be part of final unconditional waiver once final installment is paid? Thank you
