My DM is considering becoming a legal guardian for a woman with mental disabilities who has lost her parent. Letting the woman live with her and looking after her. My question is whether that will make the woman entitled to DM’s house (which is willed to me and my siblings) or financial support from her estate if DM dies? We’re happy for DM to look after this lady if she chooses to do so but not if it gives her entitlement to DM’s estate.
