Every closing document, timestamped for the file.

A residential closing runs to a fixed date with a checklist that can't slip: government ID and identity verification, the void cheque, mortgage instructions from the lender, the property insurance binder, a condo status certificate, the existing survey. The client is often selling the house they've lived in for forty years and doesn't do email attachments. Sealio's client page is deliberately plain, the reminder cadence tracks the closing date, and every request and receipt lands in a timestamped log that stays with the file. Links expire and can be revoked the moment the deal closes.
