So, you decided you want to be a model. You’ve gone through the proper channels and now actually have a contract in front of you, but, before you sign on the dotted line make sure you know what you are signing. First, invest in an attorney, especially if the agency is new or very small. There so many scams out there trying to victimize young women and even young men, it is always better to spend a few hundred dollars upfront to avoid heartbreak, financial loss and even embarrassment later.
Even though it will cost you money upfront, it is far better to have an attorney review your modeling contract to avoid any misunderstandings later.
Exclusive Contracts – This means that you work for one agency and only one agency. Anyone that wants to specifically book you for work must go through this agency, and, this agency earns commission on your earnings. (Be prepared to shell out as much as 20% if you’re signed with a top modeling agency and finding yourself very much in demand.)
Non Exclusive Contracts – This means your primary agency may find work for you, but, you’re also free to find work yourself and even sign with other agencies in non-exclusive contracts.
One Time Contract – Pretty self explanatory. Simply put, it is a one time job, however, if the company hiring fails to pay then your contract (provided it is written properly) will allow you to sue in a court of law for breach of contract.
Mother Contracts – These can get complicated fast! Absolutely get an attorney involved because it means that if you switch agencies, the original agency has the right to earn commission from you too. (And there goes your paycheck!)
