Gave contractor the last check of 15k and he died.

[Daniella Spears]

I've was almost completely done with a new build in Dawsonville Georgia and I gave my contractor the last check of 15k and he then passed away.  His son worked with him too and said to save all my receipts and he will reimburse me whenever he gets through probate and can access his funds.  I can't seem to find the passed away contractors address (maybe he just rents) and now the son ghosted me.  Do I need a lawyer to file a claim on his estate?  I called the probate office but they said the case isn't shown yet and to call back later.  Any tips would be much appreciated!!   Thanks so much BP fam!
