Seller has dementia. How to avoid lawsuit?

[Jay Poires]

I’m in the process of purchasing a property via a wholesaler and we’ve scheduled the closing at a title company I’m familiar with. I was just made aware that the woman selling the house has “dementia” (I don’t know how severe) and since her husband has died she wants to be rid of the house. It has been unoccupied for 8 months. We’re ready to close ASAP.

Do I need some document at closing which attests to her mental capacity to make this decision? Trying to reduce my chances of getting wrapped up in a lawsuit down the line.

Thanks!
