Zakaat between adoptive parents and children

It is permissible for adopted children to discharge their Zakaat by giving it to their adoptive parents and vice versa. This is subject to the condition that they are eligible recipients of Zakaat.

Note: Biological children cannot discharge their Zakaat by giving it to their parents and vice versa.

Hence, in the enquired situation, your Zakaat will be discharged by giving it to your adoptive parents if either of them is an eligible recipient of Zakaat. After the Zakaat is given to either of them and transferral of ownership takes place, it will be permissible for you to partake of meals made by them for you and to benefit from any financial support rendered by them to you. This is because after the Zakaat is discharged to them, the money received is regarded as normal funds for them which they may utilise as they wish.

And Allah Ta’ala Knows Best
