Montenegro: passport and entry requirements
Montenegro isn't in the EU or the Schengen area, so a UK family visits visa-free on its own 90-day allowance. There's a registration step to sort within a day of arriving.
Your passport
Montenegro applies the same passport rules as the EU. The passport must have been issued less than ten years before the day you enter, and still have at least three months left on it after the day you plan to leave. The ten-year test mainly affects passports renewed early, before September 2018, when the extra months added on don't count. Go through each family member's passport as you book, however young, since children's last five years against an adult's ten.
Getting in
There's no visa for a holiday, and you can stay up to 90 days in any 180-day period. Montenegro isn't in the Schengen area, so this is a separate allowance, and time here doesn't use up the 90 days you're allowed across the Schengen countries, most of the EU plus a few neighbours.
There's no digital border registration here, so your passport is stamped the old way. Check yours is stamped both on the way in and on the way out, since that's what shows how long you stayed.
Every child needs their own passport, from newborns upward, since none can travel on a parent's. Make sure each child's passport is stamped on entry and exit alongside yours.
Registering within 24 hours
Within 24 hours of arriving in Montenegro you register with the local police or tourist office. A hotel or campsite does this for you as part of checking in, so it only falls to you if you're staying somewhere private, such as an apartment or with friends.
