Not sure that it is any of your business, or germane to my enquiry, but he may want to be buried in the same grave as our Mother, which we would certainly not want. On that issue I am fairly sure about our situation, as I am the registered owner of the grave and nobody can be buried in it without my permission.
He also owes my side of the family a sum of money, due to the sale of their flat, which went through 2 years ago. My mothers Will said that he had security of tenure until HIS death and then the flat would be sold and the proceeds split up, in accordance with her will. He had a similar "mirror" will, if he had predeceased her.
