My 17yo has a moderate learning disability. I feel that she is capable of making her own financial decisions on a day-to-day basis. She tends not to see the big picture, and her arithmetic skills are somewhat basic, but she is sensible and takes advice from people close to her. By the time she moves out of home in 5-10 years, I should think she could manage a weekly budget.
The issue is that she is vulnerable, easily led. She desperately wants to be liked. If anyone is cross, she always thinks it's her fault. I can quite easily imagine her being taken in by a romantic partner who is exploiting her deliberately, or who is simply bad with money and genuinely thinks a "loan" from her will fix their problems. Or by a friend. Or by a persuasive salesperson.
When she turns 18 next year, she'll get access to her £35k Child Trust Fund. She might inherit several hundred thousand pounds when DH and I die. I was thinking now is a good time to persuade her to put her CTF money into a trust as soon as she gets it. I could ask her sibling and her cousin to be trustees after my death. Both are very competent and would always have DD's best interests at heart.
Is there any reason not to do this?
