Does anyone know the best way to get certified copies of a naturalisation certificate? The Home Office website only talks about replacement ones (does not seem like you can order a 'copy' like you can do with birth certificates for example). Would using the post office to certify a copy or a solicitor be acceptable? (it is for other forms of ID, so I'd think so, but lack of information is making me question it and don't really want to send off the only copy I have for a passport application)
