Hi all, looking for some advice. My Nan recently passed away and I’m the executor of her will. It leaves 25% to me, 25% to her step-son, and 50% in a trust originally intended for my late father (her biological son). Since he’s passed, I have discretion over the trust—whether to keep it or gift parts of it. The estate is worth around £350k after costs. This effectively means that I get 75% and he gets 25%.
For context: Nan owned a house with my maternal grandad, later remarried, and lived with her second husband (deceased 30 years ago) for 20 years. Together, they got a new mortgage to buy out my grandad's 50% share (so 25% each).
His son (the step-son) believes the estate should be split 50/50 between us and is urging a deed of variation—threatening to contest the will if I don’t agree. He has three children, who weren’t included in the will, but I’m considering gifting them £10k each from the trust.
What is fair? Any advice would be greatly appreciated.
