Hi, I heard back today from Durham office, seems my mum sent a shortened birth certificate which they wouldn’t accept and they requested a marriage certificate despite my parents divorcing many years ago. It seems so excessive in this day and age to request originals from the grandparents, when they are all in the system for their own passports,hmrc, dvla etc etc with the difficulties of applying overseas as it it. Frustrated. Clutching at straws but they didn’t mention the babies photo so I’m hoping that met their standards.
