Do you need a birth certificate to get married?
There is no blanket requirement to produce a birth certificate to get married. It becomes relevant mainly when you do not have a valid passport, in which case it can form part of the alternative identity evidence your register office accepts.
The general position
The legal requirement is that your identity, age and nationality are verified at your notice appointment. A passport typically does this on its own, which is why many people never need to produce a birth certificate at all.
Where it becomes necessary
If you have never held a passport or yours has expired and cannot be renewed in time, a birth certificate alongside other documents can help establish your identity and age instead.
Practical advice
Ask your own register office what they will accept before assuming you need a birth certificate — accepted alternative-evidence combinations vary between councils.
What this means for you
- Do not order a birth certificate as a precaution if you already hold a valid passport — it is unlikely to be needed.
- If you lack a passport, check the exact combination of documents your council accepts well before booking.
