My uncle started a probate service with a soliciting company for my father's estate, who now will only deal with us. He hadn't left a will. The only information we received from them was a letter saying that we had granted them permission to carry out the service and wanted us to sign a letter saying that we accepted these terms. I had signed and sent it back but called them within 5 days to stop all services. My sister had not returned the letter, and we were both executives of the estate (she lives in Spain).
They are now saying that we owe them a large sum of money for all the work that they had done, but none of the work they have done we had agreed to initially, and the majority was prior to their communications with us. They will also not release the documents of my father's estate until this payment is made.
We've looked at the breakdown of the costs and I have decided that I am willing to pay approximately half but feel the work done without our consent shouldn't be paid for. Is this fair?
