In the contract between the agency and the model, certain regulations are specified. Contractual terms include: business hours, fees, working hours, secondary employment, wellbeing (illness, etc), grant of rights, confidentiality, cancellation period and many others. The contract sets in writing the rights and obligations of the parties. Without a signed contract, the model will not be offered to the client, as the agency may only provide an invoice on behalf of and for the model. Also, no buyout agreements may be made if it is not consented in writing by the model or her guardian. The written agreements are very important for the model, as they protect her from data/image rights abuse and sale of image data.
