Common reasons a bundle is rejected

- Treaty claims require the article to be cited correctly on the form.

An advisor, not only a document processor
Before any work starts, our team assesses how many certification layers your document actually needs, which authorities are involved, and the correct order for the office you will really file with. One step out of order usually means restarting the whole bundle. More than 15 years of cross-border document work means we recognise how each authority rejects files and prevent it up front.
- The certification route is matched to the receiving authority before work begins.
- Rejection risks are checked, from name spelling to document validity windows.
- The filing sequence is planned around the deadline you actually have.
