If a retail store, restaurant, or other private business has formally banned you from their property (typically following a prior incident like shoplifting), entering the property again can support a trespass charge. The ban is enforced through trespass law — the retailer issues a written or verbal ban, and any subsequent entry triggers the trespass charge. These charges are particularly common with chain retailers who maintain ban lists across all locations. Defense work in trespass-after-ban cases often focuses on whether the ban was properly communicated, whether the time period of the ban had expired, and whether the person actually knew they were banned from the specific location.
