Assalamualykum,
Can a child who is 16 years of age, receive zakat although have child trust fund, bearing in mind that they cannot access the money until they are 18
Wa alaykum salaam,
If the funds in the CTF cannot be accessed whatsoever and the child is Zakat eligible otherwise, then it will be permissible for such a child to receive Zakat in their current status.
The Fuqaha discuss the scenario of Ibn Sabil who may have abundance of wealth in their country of residence but do not have funds at present. They mention that although he is wealthy from one aspect, he can receive Zakat from another angle.
Allah knows best
Jazakallah Mufti Saab
