Such service contract will be governed by the ordinary principles of contract law, which means not only that parties can freely agree the terms and conditions of their agreement but also that each party has to act in good faith. This principle may moderate certain aspects of the agreement so that - unless specifically agreed - one party cannot terminate the contract without any notice or indemnity.

It is, however, preferable to lay down all terms and conditions of the agreement, not only to determine both parties' rights and obligations, but also to ensure that both parties have a correct understanding of the agreement.
