This is perfectly standard OP, loads of people do it this way. You go sign all the legal papers at the reg office, then have the "actual wedding" with the celebrant.
Except that you don't just 'sign papers'. You actually make your vows to each other at the registry office.
Which is the actual wedding. Not the "actual wedding", in scare quotes, which is not, in fact, a marriage ceremony.
I think a few posters above think you had a secret wedding
Because she did.
Why the bloody hell did mil ask? The celebrant should have kept her gob shut and said she didn't know. But I'm not sure if they're allowed to "lie", as it's legally a matter of public record.
Nope. Not the fault of the person doing their job and telling the truth, nor the person who for whatever reason asked a question (and was right to ask it, so not that inexplicable really).
But the fault of the person who deliberately deceived their closest family and told a very hurtful and unnecessary lie.
