Injunctive relief is enforced by contempt, and contempt requires a clear order. Drafting is therefore substantive.
Specificity. The order must state the reasons for its issuance, its terms specifically, and describe in reasonable detail the acts restrained or required, without reference to the complaint or another document.
Operational language. Say what the person must do or stop doing, in terms their operations staff can follow. An order to cease unfair competition is unenforceable; an order to stop using a defined customer list and to return identified files by a date is enforceable.
Who is bound. The parties, their officers, agents, servants, employees and attorneys, and other persons in active concert or participation with them who receive actual notice.
Duration and review. An end date, or a mechanism for modification on changed circumstances.
Compliance mechanics. Certification of compliance by a date, a return protocol for materials, and access for verification where warranted.
Carve-outs. Conduct that remains permitted, stated expressly, so that the order does not sweep in lawful activity.
Bond amount and the mechanics for its release.
Proposed orders submitted with the motion, drafted as you want them entered, which is how most injunctions are actually written.
