My brother passed away this year, leaving my mother as his nominee instead of his wife due to trust issues. Now, his wife is seeking a succession certificate for herself. We’re concerned about how this will affect my mother and her ability to secure the future of her grandchildren. My mother doesn’t need the money, but wants to ensure it’s used for the children and not spent by my sister-in-law. Could we establish a trust to manage the funds, allowing the interest to be used for the children and the principal amount to be given to them upon reaching 18 years of age?
