Wedding Planning Timeline: A 12-Month Guide

A wedding plan works best in the order that decisions lock each other in: the date and venue first, then the people who make the day, then the paperwork, then the details and traditions. If you’re starting later than a year out, do the same steps in the same order — just closer together. The one genuinely fixed step is the ROM filing window, so we anchor the timeline to it. These legal steps are for civil marriages registered with ROM; a Muslim marriage is registered through ROMM, which has its own paperwork (a Kadi/Naib Kadi, the bride’s wali and two male Muslim witnesses aged 21+) and a 150-day application validity — see our ROMM guide.

12+ months before: the decisions everything depends on

Set a budget and a rough guest count together — each shapes the other, and guest count is the biggest cost driver. See how much a wedding costs.
Choose the date. If auspicious dates matter to your families, check them early; peak-season Saturday slots at popular venues book 12–18 months ahead.
Decide the shape of the day: ROM and banquet together or separately, and which traditions you’re keeping.
Book the venue. It fixes the date, capacity and much of the budget, so it comes before most other bookings.

9–12 months before: the people who make the day

Photographer and videographer — the hardest to replace; book once the date and venue are fixed. A combined photo-and-video package is often better value.
Attire — decide rent vs buy, and how many looks you want; custom pieces need months.
Makeup artist and any pre-wedding shoot.
Read every contract before paying a deposit — see our vendor questions checklist.

About 6 months before: the ROM step

This is the earliest you can file. The Registry accepts the Notice of Marriage up to 6 months before your solemnisation date and no later than 21 days before it. If you want to solemnise at a Registry site, pick an available slot when you file — slots are first-come, first-served and not guaranteed. If you’re marrying at your own venue, invite a licensed solemniser — the Registry suggests doing this 3–6 months ahead — and make sure they accept your invitation through the portal. Choose your two witnesses (both 21+) and gather the identity details the application asks for. The whole process, the fee and where you can solemnise are in our ROM guide; foreign couples should also read the 31-day residency rule.

3–6 months before: details and traditions

Rings — allow time for sizing and engraving.
Invitations — design, print and set an RSVP date so the seating plan can follow.
Traditions and family roles — agree which customs you’re keeping, such as the Chinese guo da li and tea ceremony or, for a Malay-Muslim wedding, the hantaran and akad nikah.
Hair and makeup trial — book it and plan the morning backwards from the makeup start time.

1–3 months before: confirm, don’t choose

Final guest list and seating plan.
Confirm every vendor in writing — times, addresses, contacts and what each delivers.
Transport, red packets and a day-of coordinator if you’re using one.
Complete your verification and declaration. Eligible couples (both Singpass holders, first marriage, 21+) can do this online — both parties should sign at least 10 days before the solemnisation; others attend an in-person or approved video-link appointment shown in the portal.

The last two weeks

Send one final rundown to your emcee, coordinator and every vendor, with a single contact person for the day.
Confirm the morning’s timings and pack an emergency kit.
Stop making new decisions — nothing settled in the final 48 hours tends to improve the day.
