Remember to listen to your conscience as you write. Use words that have a quick and certain meaning. Write so clearly that a nonlawyer can understand it. In technical contracts where jargon is necessary, explain it in words laymen can comprehend. Write in short sentences using active tense.
Long sentences written in passive tense are boring.
Be consistent, not creative, in terminology. Maybe an English teacher would grade this down for a short story and call it repetitive, but in contract writing it is called consistent. Make it easy to navigate the document. Give each paragraph a heading and underline it. Group paragraphs logically.
