A read of one promotion, twice. First the published terms read cold, so the promotion they actually describe is recorded rather than assumed, then compared clause by clause against the mechanic you describe in the brief — how somebody enters, how a winner is chosen and what they get. Every particular a reader needs checked for presence and clarity: promoter identity, closing date and time, eligibility by age, territory and status, the entry route including any free alternative stated, how and when a winner is chosen and by whom, the prize and every qualification attached to it, notification, claim periods and unclaimed prizes. The document then tested against itself for contradictions and clauses inherited from an earlier campaign. Finally every claim in the advert, landing page, social copy and on-pack wording matched to the term that supports it, and listed where none does. Three business days from the brief arriving. Not legal advice, no view on whether a promotion is a lottery or needs a licence, nothing approved or certified, and no terms redrafted.
