Yes, you would just need to include "Parent of Minor" in the endorsement area on the check. Alternatively, if you are able to see your children’s accounts from within your online banking, you will have the option to deposit the check into their account and would only need to endorse the back of the check to read, “for mobile deposit only”.
If your child is not a minor, and does not have an account linked to yours, you will need to take this check to a branch with the child and proper ID as it is considered third party.
