Our existing process has been to update the primary contract pre-lien with the subsequent change orders. This however does not favor the sub-contractor, as I don’t want the lien dates to be continually reset for relatively small change orders. I would prefer, if the change orders are over $1000, to submit pre-liens on those and let them stand on their own. I have an example of a primary contract order of approximately $150k. The primary job is now complete and I want the lien clock to start, so I will press for final payment within 60-days, on the outside. We may be getting a change order for around $1500, which I would like to treat separately and not reset the clock on the main job. Is this an acceptable approach and fall within the lien rights of sub-contractors?
