Start with the last person’s actual route
Walk through a normal closing in the order it happens. Name the specific checks that matter in your home, such as looking at the oven controls, locking the back door, and placing the keys where the morning adult expects them. Avoid vague entries such as “make everything safe,” which cannot be checked in one action.
Mark this occasion, not yesterday's
A paper list can have a fresh dated column for each evening. A reusable list needs an obvious way to reset before the next use. If someone reopens a checked door after taking out rubbish, they need to close and check it again. The earlier mark is no longer evidence about its present state.
Trial the list with a different adult
Try the checklist in the physical order you move through the home. If the last person regularly doubles back to the kitchen, reorder the checks. Use a fresh completion mark for each occasion rather than trusting a tick from the previous evening.
Ask the other person to use it on an ordinary night. If they pause at “keys away,” specify which keys and the agreed private location without exposing it in a public note. If an entry never changes anyone's action, remove it. The list should support attention and a reliable handoff; no checkbox by itself proves that a physical condition still holds.
