Relative's brother died while in escrow of purchasing new build.

[Pamela Baker]

What is the protocol for the following scenario:

My sister in law's brother is purchasing a new build home.  He is in escrow waiting for the completion of the new build.  Unfortunately, he died yesterday.  What is the protocol.  Does the down payment/earnest money go away, or is there a way for my sister-in-law to recover the money.  Is there a way for her to continue with the purchase?  There is no wife or kids in the picture so the sister would like to either complete the purchase or get his money back.  Does she have a leg to stand on?
