I mean even grown adult models.
If you get them to sign the forms without telling them what it is for, what they would sign away in the MR..
SPH ever quietly settled a case out of court with a model before, because she wanted to sue them. They paid her to do a shoot with the understanding that it was for something, but when they started using her photos for advertisement purposes, she countered that it was not correct.
In the same case, I'm not sure if it applies, do correct me if i'm wrong, but if the photographer tells the model that it's just to protect the model and himself, but subsequently sells her photos, he's still open to suits that he misrepresented the extent of the contract.
