Hubert and Wilma married in 1960. Hubert died in 1998 and left everything to his wife. Wilma's current estate is valued at $1,500,000; a home, a cottage, and savings, each with a value of $500,000. Wilma is now eighty-two and is in the process of updating her will. She is not sure how to distribute her estate amongst her three sons David, Siegfried, and Roy. She is meeting with you, her financial planner, for some advice. One option Wilma is considering is to transfer ownership of the cottage to all three children. She wants to ensure that when one of her sons dies, their one-third ownership remains with his family.

What ownership structure would ensure Wilma's wishes are honored?

a. JWROS between all three sons

b. Tenants-in-common between all three sons

c. Sole ownership in the name of the youngest son

d. JTWROS between all three sons and their spouses
