If you are dissatisfied with the way a campaign is going or its results, and have tried but failed to work with the agency to bring your relationship back on course, you may want to end the agreement.
In either situation, you should first consult your contract. Check its provisions for:
procedures in the event of a breakdown in the relationship
notice periods
copyright ownership
When ending the relationship you need to be clear about:
Any compensation you may need to pay for early termination of a contract.
Who owns the intellectual property rights to the creative material that the agency has produced. Can it be used by any subsequent agency you engage? Read more about copyright for your business.
If in doubt, you should seek the advice of your solicitor or business adviser.
