This document is GDPR compliant.
Use this model release letter or waiver to obtain permission from an individual to use material featuring their image, or the image of a child of whom they are the parent or legal guardian. Having a signed waiver can give a business protection should the individual appearing in the material decide to bring legal action against them.
In general, when material is being used for commercial purposes, a model release form should be obtained from the people being featured. This is because their image constitutes personal data for the purposes of the data protection regime.
