Apostille vs. Legalization

What the route depends on: check the Convention between both States

International document authentication is not decided by the destination country alone. For an eligible public document, the deciding factors are whether the 1961 Hague Apostille Convention is in force between the issuing and receiving States and whether an exemption applies to the document and procedure. The treaty relationship between the two countries — not a fixed destination list — determines the route:

An apostille authenticates the document's origin; it does not guarantee acceptance of its contents. Spain, Mexico, Colombia, Argentina, the US and the UK are Convention members, and apostille is the standard route between them when the document qualifies. The UAE, Qatar and Kuwait are not parties, so documents going there follow the consular chain the receiving State sets. Recent accessions — China (in force 7 November 2023), Canada (11 January 2024) and Saudi Arabia (7 December 2022) — show the map keeps changing, and some States have lodged objections to recent accessions, so we always verify the specific issuing–destination pair:

1. Check the Convention's entry into force and applicability between the issuing and destination countries — including objections and exemptions
2. Identify the correct competent authority — federal or state apostille, or which embassy for legalization
3. Prepare and submit documents with certified translation where required

We handle the complete process in one coordinated service — apostille or full legalization chain, with certified translation included in Standard and Rush packages.

Common rejection reasons — and how we prevent them

Most rejections happen because the wrong process was used or the wrong authority received the documents. Our pre-submission review catches every issue before it costs you time and money:

• Using apostille for a destination where the Convention does not apply — An apostille is not the recognised authentication for documents destined for the UAE, Qatar, or Kuwait, because those countries are not parties to the Convention. In those cases the receiving authority requires its own legalization procedure and may reject an apostilled document. We confirm both States' treaty status and the receiving procedure before processing anything.
• Using legalization when apostille suffices — Going through a full consular chain when a simple apostille would work wastes weeks and money. We identify the correct and most efficient process for your specific destination.
• Wrong apostille authority for US federal documents — FBI Identity History Summaries and other federal documents must be apostilled by the US Department of State. Sending them to a state Secretary of State causes rejection. State offices have no authority over federal records.
• Photocopy submitted instead of original — Apostille and legalisation rules on document format are set by each competent authority. Check whether the original, an officially certified copy, or a verifiable electronic document is accepted; do not present an uncertified photocopy as the original.
• Missing intermediate steps in the legalization chain — Sending a document directly to the embassy without state and federal authentication first is a complete rejection. We manage every step of the chain in sequence.
• Document expired for immigration purposes — An apostille does not set the underlying document's age limit: each receiving procedure publishes its own freshness rule (verified Spanish checklists range between three, five and six months). Check your procedure's current checklist. We flag all timing issues before submission and advise on re-ordering documents where necessary.
