The following two sections of our Master Services Agreement establishes who (as in, a specific person) is responsible for managing the relationship on behalf of your client. This is a critically-important bit of information to establish on a contractual basis when more than one stakeholder is involved in decision-making. Once the work has begun, make sure that important decisions are communicated back and forth through this person.
2. Cooperation
The Client's Representative should be a party to all important decisions and project communications. If they are not directly the person involved in a decision or communicating it to you, make sure they are at least CC'd (assuming email). These clauses are your protection from accusations of having acted in a reckless or otherwise unauthorized manner.
Make sure to make an amendment to the agreement if the identity of the Client's Representative changes during the term of the agreement. At no point in time do you want it to become vague or unclear who it is that should be giving you definitive directions.
