My cousin's daughter is in a relationship with a controlling man. Her daughter used to be close to all of the family but abruptly cut them off entirely for six months, ignoring texts and calls. She now has occasional contact, her daughter will speak occasionally or text thank you for any birthday gifts etc (cousin can only give money as she has bank account details from when she supported her as a student but no address as daughter moved without giving it to her). Daughter has also cut off from all of her friends.
Cousin has recently found out that daughter married over 6 months ago and is thinking of changing her will, maybe by leaving daughter's share to her children or trying to set up some sort of trust. She doesn't want her son in law to have access to any of her money or assets. On the other hand, she doesn't want her daughter to feel unloved or excluded. She has three other children. She is very wealthy.
My cousin is in her 60s and, so far as I know, in good health, so not a pressing issue in some respects, although we never know what is round the corner.
So, should she change her will and, if she does so, should she tell her daughter?
