How to Organize a Multi-Document Apostille Project Without Documents Expiring at Different Times

When a single project involves several documents, each with its own origin and its own processing pace, it's easy to end up with some documents apostilled and ready while others are still in process, only to find that by the time the last one arrives, the first one has already passed the maximum age the destination accepts. This guide explains how to organize a multi-document project so the whole set arrives ready and valid at the same time.
To keep a multi-document project from expiring in pieces: 1) make a complete list of every document and its origin before requesting anything; 2) confirm with the destination the maximum age it accepts for each document, since this varies by country and by document type; 3) identify which documents tend to take longer or have the shortest validity window, and start those first; 4) request in parallel the documents that don't depend on each other; 5) keep a simple tracking list with the status of each one.
