Mary is in her 80s. Her DH died 15 years ago.
Two children
Jane in her 60s with two grown up children.
Sarah who died a decade ago in her 50s. Left a widower and two grown up children.
Before Sarah's death Mary's will basically divided the estate 50/50 between 2 daughters with a small amount for each grandchild eg £5-10k
Since Sarah's death, Mary has made changes. 50% will now go to Jane, the remaining 50% will be divided equally between the grandchildren. Sarah's husband will also like get something too.
Sarah's children have somehow found out about this (not sure how) and aren't happy. They feel like they're not being treated fairly as the original 50% for Sarah is no longer coming to that part of the family, but a smaller share, while Jane still gets 50%.
Jane will be using her share as an extra pension as she's not got a great one. Sarah would have likely done the same so these sums were never going to be passed directly to grandchildren but obviously they would benefit indirectly.
Obviously Mary can do what she likes with her money but this is causing friction and interested in perspectives. Inheritance seems to always cause feuds.
