To write a simple contract, title it clearly, identify all parties and specify terms (services or payments). Include an offer, acceptance, consideration, and intent. Add a signature and date for enforceability. Written contracts reduce disputes and offer better legal security than verbal ones.
Ing to Boundy (2012), typically, a written contract will include: Date of agreement. Names of parties to the agreement. Preliminary clauses. Defined terms. Main contract clauses. Schedules/appendices and signature provisions (para. 5).
