How old do you have to be to get married in Great Britain?
In Great Britain you have to be at least 16 years old. If you are 16 or 17 (boy or girl) you need your parents' consent in England and Wales, but you can marry in Scotland without consent. If you lied and said you were 18 so you didn't need your parents consent the marriage would still be valid. However if either of you were not yet 16 and lied about it the marriage would be void.

Great Britain as a sovereign nation dates from the union of Britain (England and Wales) with Scotland in 1707. The modern nation is more specifically the United Kingdom of Great Britain and Northern Ireland, which dates from 1801 (all of Ireland) or 1922 (just the northern section of the Irish island).
