The contract for most of the ghostwriting services is the same. The formal document must have details of the work the agency is supposed to do for you. It should include the timing for every step the company has mentioned. For instance, the time when you get the first draft or the deadline for the final version. Also, the fee amount and fee schedules must be added to ensure that you pay for what you are getting. Lastly, after paying the full amount, the copyright of the work should be transferred under your name.
