How to Legalise Business Documents for International Use from the UK

Expanding your business internationally? Your UK business documents may need to be notarised, apostilled, or legalised for use overseas.

What Does It Mean to Legalise a Business Document?

Legalising a business document means completing the required verification steps so that it can be accepted for official use in another country. Depending on the destination and type of document, the process may include notarisation, apostille certification from the Foreign, Commonwealth & Development Office (FCDO), or additional embassy legalisation.

The required steps vary based on the document type and the regulations of the country where it will be submitted.

How to Legalise Business Documents for International Use from the UK

Legalising business documents is straightforward when handled by experienced professionals. Here’s how the process typically works.

Step 1: Send Us Your Business Documents

Securely upload or send your documents for review.

Depending on your requirements, you may submit:

Step 2: We Confirm Whether Notarisation Is Required

Not every business document follows the same legalisation process.

For example:

  • Certain official Companies House documents may be suitable for direct apostille certification.
  • Private corporate documents, such as contracts, board resolutions, or Powers of Attorney, often require notarisation before an apostille can be issued.


We assess your documentation and advise on the correct legalisation route based on your specific requirements and destination country.

Step 3: Notarisation (Where Required)

If your documents require notarisation, the process can often be completed remotely using our secure online notary service.

This may include:

  • Identity verification
  • Review of the corporate documents
  • Verification of signing authority where applicable
  • Witnessing signatures when required
  • Official notarisation by a qualified notary public


This ensures the documents meet the requirements for international recognition.

Step 4: Apostille Processing Through the FCDO

Once your documents are ready, they are submitted for apostille certification through the Foreign, Commonwealth & Development Office (FCDO).

The FCDO verifies the signature, seal, or certification on the document before issuing the apostille certificate.

Where eligible, some electronically signed documents may qualify for an e-Apostille, while others require a traditional paper apostille. (GOV.UK)

Step 5: Receive Your Legalised Business Documents

Once processing has been completed, your documents are returned ready for international use.

Depending on your requirements, delivery options may include:

  • Secure courier delivery
  • Postal return of certified documents
  • Electronic delivery where appropriate


Throughout the process, our team keeps you informed and provides support from submission through to final delivery.
