The one thing wedding apps built for the US always get wrong. In England & Wales you must legally give notice at your local register office at least 28 clear days before the wedding (this is the England & Wales rule; Scotland & NI use ~29 days) — and you can't do it more than 12 months ahead. Both partners give notice separately, in the district where they live. Miss this window and the wedding can't legally go ahead, however perfect everything else is.

Which legal path are you on?

• Register office or approved venue → a registrar conducts the legal ceremony. Requires giving notice (below). Rosewood Manor should be a licensed venue — confirm its wedding licence is current.
• Church of England / Church in Wales → usually banns read in church on 3 Sundays in the 3 months before, instead of civil notice. Speak to the vicar ~6 months ahead.
• Other religious / celebrant-led → a celebrant creates a beautiful bespoke ceremony but is not legally binding on its own — you'll also need a registrar (often a small register-office ceremony separately). Budget for both.

Checklist

• [ ] Confirm the ceremony type & that the venue holds a current marriage licence
• [ ] Book the registrar / speak to vicar about banns (do this early — registrars get booked up)
• [ ] Both partners book notice-of-marriage appointments at your local register office
• [ ] Give notice — ≥ 28 clear days before (England & Wales), and within 12 months of the date
• [ ] Take required ID & documents to the appointment (passport, proof of address, and if applicable divorce decree absolute / former partner's death certificate)
• [ ] Pay the notice fee (typically ~£35 per person)
• [ ] Confirm 2 witnesses for the day
• [ ] Decide on names/vows/readings with the registrar or vicar
• [ ] Collect the marriage certificate after the day
