So I work in this area and odds are (with SG's knowledge/wealth and NG's wealth and age) NG may have a trust, not a will. A will is basic and has to go through probate, a time-consuming, expensive, public process. A trust would manage more assets, do so privately, and can set things up financially for grandkids, charities, etc. People would still be beneciaries and get money when she passed away. It would also manage the money that NG lives on and protect it in case nursing home care is needed, etc. But it would all be managed by a trustee. A trustee can be a family member, friend, or a bank/corporation. How this factors into a financial motive may still be the same as if it were a will. I just wanted to clarify in case it matters!
