Loan terms changing after borrow is deceased
My grandmother recently passed away and my mother is handling her trust. She had a small home equity loan for about $12k with a NY Credit Union. About 6 months ago she paid a large portion on the loan and the credit union showed she was paid ahead until 2012. Now that she is deceased the credit union is changing how that payment was applied. They are no longer allowing that large payment to go toward future payments. They also want $3000 to cover the last 6 months worth of payments or they will foreclose. My question is can they apply the payment one way and now learning my Grandmother is deceased change how the payment was applied and demand payments for the last 6 months? It seems like they are trying to scam the estate by foreclosing on a house that is worth $95,000. Will all the funeral costs my mother is afraid she will lose the house if she can't come up with the cash to pay the credit union. I'm wondering if they can legally do this?
