Authorization form needed please .....

[Huso Akaratovic]

Greetings, 

I was in the forum section attempting to locate an authorization form, but there was no luck. My tenant is requesting from me in writing that I authorize a cable company to connect their services in the unit. Apparently  they need to come down the attic into a ceiling from what I understand, and they need my permission. I just want to make sure that I have proper forms covering me before I authorize this work. Any help is much appreciated. Thanks everyone!!
