Sub refuses to sign lien waiver

[Tom Henderson]

Hello Team!

Quick question for you-- I recently completed a complete gut/renovation on a duplex in Minneapolis. 

For my final draw (I used a construction loan from a private bank), the title company is requesting that all subcontractors sign a lien waiver. Unfortunately, they told me this after some of the subs finished their work.

Everyone has been very responsive-- painting, electrical, plumbing... My tile/granite guy has gone completely dark on me. He has a history of doing this in the past, but this is extremely frustrating because a large amount of money is due to me (I've already paid out-of-pocket, and am waiting for this. 

I'm curious if any of you have every dealt with an issue like this? How would you corral him? Is there an alternative way to time-stamp that efforts were made to sign a lien waiver, but the contractor refused? From a title company standpoint, I totally understand they want to reduce all risk... any feedback/thoughts/ideas you have would be greatly appreciated.

Thanks,

Tom
