This template gives you everything you need for a professional, customizable and legally binding Release Photo Minor Child Agreement.
Anytime someone wants to photograph a child and use those photos for any purpose beyond personal use. Parents or guardians must give permission since minors can't legally consent to photo releases themselves.
Depends on what the release specifies. Some are for single events, others might last for the school year, and some continue indefinitely. Parents can usually revoke permission for future photo use.
Photos of minors shouldn't be used commercially or publicly without proper releases. Organizations could face legal problems for using minor photos without parental permission.
