Here at CARFAC BC, we always say you can never go wrong with a good contract, in any arts setting!
Our friends over at the Pacific Legal Education & Outreach Society have created a great basic contract for artists, available below. They are a fantastic organization that works to create better legal rights for artists, and we often work with them. Please check out their website at https://www.pacificlegaloutreach.com/
If you need more variety in your contract, CARFAC BC has more variations of sample contracts for artists to use, all of which are available to our members for free. Having a strong, basic contract you can apply to any situation as an artist is vitally important to protecting yourself and your art.
