As provided by the legislation, the application for postal voting must necessarily reach the municipality where the voter is registered to vote:
- At the earliest 12 weeks and at the latest 25 days before the day of the election (i.e., May 15), if the summons letter is to be sent to Luxembourg;
- At the earliest 12 weeks and at the latest 40 days before the day of the election (i.e., April 30), if the summons letter is to be sent abroad.
If the application for postal voting is accepted, the municipality sends the voter their summons letter by registered mail. The summons letter is sent at the latest:
- 15 days before the election, if the voter resides in Luxembourg;
- 30 days before the election, if the voter resides abroad.
Once the ballot is received, the voter must ensure that the envelope containing the vote arrives no later than the day of the election (i.e., June 9) before 2:00 p.m. at the relevant polling station.
