After the death of Ernst August 1953(Viktoria Luise husband) Their eldest son became the head of the house of Hannover, as such he paid money to members of the Family( His mother and siblings for example) I think Ernst August did not paid her as much as he should and his late father wanted. Mainly it was about Viktoria Luises appange but also abut Jewels, Viktoria kept some jewels that she should have given her son (the Brunswick Tiara for example) Ernst August also expected his mother retirement of social projects which she refused..
