Getting a house under contract that is currently in probate.

[Paul Kuegle]

Back Story:

I had a seller call me from one of my marketing campaigns, I checked out the property & long story short I was able to get it for the price I wanted.  I wrote up the offer to the seller & she signed/accepted.  The story with the house is the sellers parents both passed away and had assigned her to be the executor of their estate.  A few days after getting the offer signed the seller contacted me & informed me that she just found out the courts don't recognize her as the executor because there wasn't anything in writing from her parents like a will stating her as the executor.  The house is now going through the probate process which can take months for her to get the rights to the house again.  

My question:  Is there any way to ensure I still get this deal once the "seller" gets full rights to the house again?  Like promissory note or something?  Or do I just have to trust I built enough report with the seller & keep following up with her?  Any suggestions would be appreciated. Thanks.
