He refuses to sign the lease estoppel...

[Roger Doe]

What do you fellow property managers do when a commercial tenant refuses to sign a lease estoppel?

Recently, I've gotten a commercial tenant that has been particularly irksome even though the lease stipulates that a lease estoppel needs to be signed. Reason for his refusal? He says he simply doesn't want to. In other words, he doesn't give a crap and doesn't want to spend the effort in figuring out if the lease estoppel is ok to sign.

I can of course threaten him to terminate his lease but I would like to go the amicable route. Any suggestions that you, fellow property managers have found successful?
