A comprehensive ghostwriting contract should cover: the exact scope of work (word count, format, number of pieces), payment amount and schedule (deposits, milestones, final payment), revision policy (how many rounds included, cost of additional revisions), ownership and copyright transfer, confidentiality and non-disclosure terms, timeline with key milestones, and cancellation or dispute resolution procedures. Never work with a ghostwriter who resists putting agreements in writing; verbal agreements leave both parties vulnerable and often lead to disputes.
