Make an appointment with a UK notary or commissioner of oaths
to swear an affidavit - a written statement that is used to formally declare that you’re free to marry.
You’ll need to get your affidavit ‘legalised’
(certified as genuine) before you travel to Turkey.
If you’ve been divorced or widowed, you’ll need to provide:
• Evidence of nationality or residence where your divorce took place if it was outside the UK. You’ll need to get it translated
if it’s not in English
• Evidence if you’ve changed your name by deed poll
Your partner will need to get an affirmation as well
