Query for a colleague please. She is single and childless. She has a flat with life assurance to cover the mortgage and life insurance at work worth about £120k. Flat worth £100k ish. She wants to leave it all to her sibling. Said sibling has a history of financial issues (she thinks gambling is a problem). Sibling also has struggled to keep a job. Nonetheless they are close and it is logical for her to leave her estate to them. Presumably in her will she can appoint trustees and give guidance as to what she would want- suitable property bought outright managed by trustees or similar. However, is the life insurance through work different? We know that there are trustees linked to the life insurance. Would they act in accordance with a will or would she have to write a separate letter to the insurance trustees? Her parents are alive but she would not trust them to protect the money.
