Artists require many types of contracts in their work. In practice, signing a contract is relevant when an artist sells his or her work, agrees on a commission for artwork, or places work on display in an exhibition.
Contract law does not require a specific form of the contract. This means that an oral agreement is just as valid as a written contract. In practice, however, determining the content of an oral agreement can be difficult later, so it is sensible to make contracts in writing, or at least confirm the essential content via e-mail. Things are easier to check from a written contract or an e-mail message.
The reiluntaiteenmanifesti.fi website includes links to agreement templates, pay and fee recommendations and guidelines for artists and commissioners of art to help them price work accurately, negotiate agreements and budget events and other assignments realistically. The website focuses primarily on commissions, assignments and gigs, i.e. work that is not covered by collective agreements.
