Based on Singapore's Law:

Joshua was an adventurous young man with a vast estate. He married Elaine, who was equally adventurous and sporty. Elaine was 2 years older than Joshua. Joshua and Elaine did not have any children. Elaine's only family member was her sister, Elizabeth.

Joshua made the following arrangements for his estate. He made a Will (after his marriage) leaving all his assets to his 80-year old mother, Mary. He made a CPF nomination (after his marriage) leaving his CPF monies to his mother, Mary. However, Elaine did not make any Will.

Both Joshua and Elaine were on a safari tour to South Africa, when they went missing. After days of searching, the rescue team found them both dead.

After the funeral was over, Joshua's mother, Mary, was shocked when Elizabeth came to her claiming that all of Joshua's and Elaine's assets would be Elizabeth's because they belonged to her sister after her husband's death.

Apply the relevant laws of succession, inform Mary as to what would happen to her late son's estate, and how it would be distributed at law. Assume that the late Joshua's estate comprised the following:

(a) His CPF monies

(b) He owned the house with his Elaine as his 'joint-tenant' co-owner.

(c) If Joshua and his wife, Elaine, owned the bungalow as 'tenants-in-common,' state whether your answer to question (b) above would be different. If it would be different, please state your answer, assuming that the title to the bungalow were "tenants-in-common" instead of joint-tenancy.

(d) If Joshua was found dead, and Elaine was found half-alive, but she subsequently died, state how your answer would differ regarding Elaine's half-share of the bungalow if they held the title as tenants-in-common.
