With both signatures I'll feel safe, what about the idea of getting a notary to witness.  

Apology for the long winded intro to this post, but I'll get to my point as to why I think real estate along with other real assets (e.g. gold, BTC to the extent) will perform well in the next few years.I do think we're witness and living at the proverbial "Fourth Turning" as eloquently coined by Mr.

Lots and lots of nice Jehovahs' Witnesses or Latter Day Saints folk.I got along with all of them just fine. 

Do I need witnesses? 

An inspection (with a 3rd party witness) is probably in your best interests.

That could be done with tracking of some kind, or if the process server had a witness with them, maybe. 

So, either he was unlawfully working as a roofer while on SS disability or he lied in the communications we've preserved and you have a "not credible" witness.

I guess you could call me an "expert witness" of sorts. 

A tenant who wishes to terminate a rental agreement on these grounds should document carefully both the condition of the dwelling (with photographs or video and witnesses) and the tenant’s attempts to notify the landlord of the problem.

Thanks @Mark W. , It was Shepard Maxwell and Hail but bought out by Tompkins a few years ago.
