Get a certificate of no impediment by post

Here’s how to get a CNI by post. Alternatively, you can get a CNI at the British Embassy Warsaw.

  1. Download an affirmation and notice (opens in a new tab). Fill in your details but do not sign the documents yet.
  2. Book an appointment with a notary in Poland and ask them which documents you need to take to your appointment, for example proof of address.
  3. If you do not live in Poland, you must be there for 3 whole days before your appointment, starting the day after you arrive.
  4. Take your documents to your appointment and sign the notice and affirmation in front of the notary. They’ll notarise (sign and stamp) the notice and affirmation too.
  5. Apply online and pay £100 for your CNI – £50 for receiving notice (non-refundable) and £50 for issuing the CNI .
  6. Post your documents to the British Embassy Warsaw.
  7. Your notice will be displayed for 7 days.
  8. If after 7 days no one has raised a legal objection to your marriage, your CNI will be issued.
  9. Your CNI will be posted to your chosen address in Poland or you can collect it. You can select if you want to book an appointment to collect your CNI or have it posted when you apply online.

Once you have your CNI, it will be accepted by local authorities for 6 months.

Filling in your affirmation and notice

Download an affirmation and notice (opens in a new tab). Print and fill in your details by hand. The details in the documents to be notarised must match the documents you upload when you apply online. For example, enter your details exactly as they appear on your passport. If they do not match, the embassy will ask you to complete a new version of the document and get it notarised, delaying your application.

Do not sign when you enter your details. Only sign in front of a notary in Poland.

See guidance on how to fill in your documents, including examples of the notice and affirmation.

Documents to send to the Embassy
