Getting married in Luxembourg as an expat — what you actually need to know

Luxembourg is one of the most international countries in the world, nearly half its residents were born elsewhere. So it's no surprise that many couples planning a wedding here are expats, international couples, or simply navigating the paperwork in a language that isn't their first.

Good news: getting married in Luxembourg as a foreigner is absolutely doable. It just takes some planning. Here's what you need to know.

First things first: civil marriage is mandatory

In Luxembourg, a religious ceremony alone has no legal validity. You must have a civil marriage first, everything else (church, ceremony in a château, garden wedding) comes after. The civil ceremony takes place at your local commune (municipality), and at least one of you must be officially resident in Luxembourg.

Start early — earlier than you think

This is where most expat couples get caught off guard. The timelines are strict:

• 3 months before — Visit your commune to start the process (required for non-Luxembourg nationals)

• 1 month before — All documents must be submitted to the civil registrar

• 10 days before — Banns (marriage announcement) are published at your commune

Both of you need to show up together for the initial appointment, passport or EU ID card in hand.

The paperwork

The exact documents depend on your nationality, but most expat couples will need:

• Valid passport or EU identity card

• Birth certificate (issued within the last 6 months)

• Proof of residence in Luxembourg

• Certificate of single status/no impediment to marriage

• If previously married: divorce decree or death certificate

All documents must be in French, English, or German. Anything else needs to be translated by a sworn translator. Foreign documents from non-EU countries typically require an Apostille stamp.

Where can the ceremony happen?

The civil ceremony takes place at the town hall or another location authorised by your commune — many communes now allow approved external venues, which opens up some beautiful options. Your religious or symbolic ceremony can happen anywhere: a château, a vineyard, a garden, a church. Luxembourg has no shortage of stunning backdrops.

Language at the ceremony

The civil ceremony can be conducted in Luxembourgish, French, or German depending on your commune. The symbolic or religious ceremony after is entirely up to you — bilingual ceremonies are common, and many officiants in Luxembourg are used to multilingual couples.

One more thing

Every commune has slightly different requirements and available dates, so always go to your local civil registry first — they are the authority, not the internet (including this blog). The official source is guichet.public.lu.
