HELP! Seller lost trust documents. Title won't clear.

[Anthony Vargas]

So I've been working with a seller facing tax lien foreclosure and were finally about to close and she can't find her trust documents in order to clear tittle. ( Her husband passed away and gifted her the property in the trust. The property went through probate and since has not paid property taxes and is scheduled for auction in the next two weeks. I have given seller EMD outside of escrow and am now worried we wont be able to close). The attorney she used she says has since passed away and she cant recollect the firm. I was thinking if we can't locate attorney, no info comes from probate court and seller cant locate documents then we'll have to put closing off, pay her back taxes in order to stop the sale, then work on remedying the title issue (any suggestions??)
