You do not have to take their word for it and can absolutely require written evidence from the person that determined the disability and prescribed the animal.

All that said, it seems I have a significant amount of room to choose my cost basis and provide evidence for each.

Often the wind will drive water to or over an edge and the water seeps in; but when you go look after the rain slows or stops the evidence is gone.

So I then took them proof of two different incidents, via actually things that were supposed to be swapped but weren't as well as video evidence.  

Factors that may indicate a property is abandoned include vacancy, damage or disrepair of the property, underutilization of the property, never taking actual possession of the property, failure to pay taxes on the property, failure to keep the property insured, and other evidence showing the defendant owner had truly moved away from the subject property such as voting in another jurisdiction.

You didn't try to run rogue on the seller or buyer which is evident in your assignment of contract profit.   

I'm not stating that to lead people to believe that there is now some short sale windfall, I only write that as anecdotal evidence that it does not appear that banks have changed any processes or decision making standards yet.

Seller will be required to submit originals of these documents to the buyer prior to closing8.Title: Evidence of Title is to be in the form of an owners ALTA (American Land Title Association) policy through Chicago Title or other national title company.9.Closing: The Closing will occur not later than 60 days following execution of the Contract.

@Jason JonesIf a title company is involved in the transfer, they will almost certainly require your spouses signature absent evidence the the contrary that the property was legally deeded to you as separate property. 

I agree with Tom, unless there's evidence that quiet title is probable and there's a big enough spread, it may not be worth it to proceed.
