In 2025, Dutch visitors to Montenegro averaged 3.74 nights per arrival and Belgian visitors 3.57 — the shortest stays of any Western European bloc, against 5.73 for the Baltics and 5.23 for the Nordics. Together the Netherlands and Belgium produced 51,411 arrivals and 188,574 nights.
That ratio is the whole story. Dutch and Belgian owners are not the people who move in for a season; they are the people who come often, briefly, and with other people. A long weekend in May, a week in August, a few days in October, and in between the flat is lent to a brother-in-law, a colleague, friends who wanted the coast without a hotel.
Legally, that pattern produces something the long-stay owner never encounters: a large number of arrivals. And in Montenegro an arrival is not a private event. It is a filing.
The presence arithmetic itself — how the 90-day allowance is counted and why the document you travel on changes it — we set out for the long-stay profile in Montenegro for Nordic and Baltic owners. This page is about what happens each time somebody walks through your door.
Every arrival is a filing, and the clock is twelve hours
The registration of a foreigner's stay is governed by the Aliens Act (Zakon o strancima, „Sl. list CG" nos. 012/18, 003/19, 086/22, 077/24, 003/26 and 033/26). There are three separate routes, and which one applies depends on who is providing the accommodation, not on whether anybody pays.
Route one — the guest uses an accommodation provider. Under Article 97(1), where a foreigner uses the services of an accommodation provider, the duty to file the registration and de-registration lies with the provider. Paragraph 2 gives them 12 hours from arrival to file with the police in the place where the stay is registered. Paragraph 7 requires the provider to verify the data against the guest's travel document and to state truthful data. Under Article 98, the provider keeps a register of the foreigners it accommodates, retains the data for two years, and must let the police inspect it. Article 99 makes electronic filing the default, with a paper or tourist-organisation route only where the police certify there is no technical possibility.
Route two — a tourist with no provider at all. Article 100 allows a foreigner staying for tourism who does not use the services of an accommodation provider to file the registration and de-registration through the tourist organisation in the place of stay, or, where none exists, through the competent local authority. That body forwards it to the police electronically within 12 hours, and — a detail worth knowing — paragraph 4 states that this filing is not charged for.
Route three — the one nobody expects. Article 101(1) provides that a company, an entrepreneur, and a person whom a foreigner staying up to 90 days comes to visit and to whom that person provides accommodation for more than 12 hours, must file the registration and de-registration with the police within 12 hours of the foreigner's arrival, respectively departure.
Read that third one slowly, because it contains no commercial element whatsoever. It does not say "lets", "rents", "charges" or "hosts paying guests". It says visits and provides accommodation for more than twelve hours. On the plain wording, the Dutch owner who hands the keys to friends for a long weekend is inside it — and so, symmetrically, are the friends' arrival and departure, each with its own twelve-hour clock.
| Situation | Who files | Deadline | Where it says so |
|---|---|---|---|
| Guest uses an accommodation provider | The accommodation provider | 12 hours from arrival | Art. 97(1) and (2) |
| Provider's own records | The provider keeps a register, data kept two years, police may inspect | Ongoing | Art. 98 |
| Tourist using no provider | May file via the tourist organisation or local authority, free of charge | Forwarded to police within 12 hours | Art. 100 |
| Foreigner on a stay up to 90 days visiting a company, entrepreneur or person who provides accommodation for more than 12 hours | That company, entrepreneur or person | 12 hours from arrival and from departure | Art. 101(1) |
| Registration with no stated duration and no de-registration | Treated as valid for six months, or until a stay of up to 90 days ends | Automatic de-registration ex officio | Art. 102(2) and (3) |
| Cases where no registration is filed | Only two: a victim-of-violence shelter, and rescue-unit members called in after a natural disaster | — | Art. 103 |
What happens if nobody files
Article 212 sets the penalties for this group of duties. A legal person faces a fine of 500 to 3,000 euros; an entrepreneur 300 to 1,500 euros; and a natural person who provides accommodation services faces 150 to 500 euros.
Here we owe you precision rather than a scare. The duty in Article 101(1) is drafted around any person who provides accommodation to a visiting foreigner for more than twelve hours. The penalty for a natural person in Article 212 is drafted around a natural person "who provides accommodation services". Whether a purely private host — no payment, no listing, no service — falls inside that penalty wording is a question of interpretation, not something the text settles in one line. What the text does settle is that the filing duty exists and that it is measured in hours.
The practical consequence is the same either way, and it is not really about the fine: an unregistered stay is an unregistered stay, and the person it becomes a problem for first is usually the guest at the border, not the owner at home.
Short and frequent has a second consequence: the lease line
The other thing the Dutch and Belgian pattern produces is short lettings — a week here, ten days there, often to people found through a platform rather than through an agency. Where that becomes a business, it is a licensing and tax question, and we have treated it separately in Montenegro Airbnb licence and short-term rental rules and in renting out property in Montenegro: tax and legal rules.
What is worth adding here is a jurisdiction point that sits exactly on this line. Article 119(1) of the Private International Law Act gives Montenegrin courts exclusive jurisdiction over proceedings whose object is a right in rem in immovable property situated in Montenegro — a choice of a Dutch or Belgian court does not move that. But paragraph 2 carves out one situation: for proceedings arising from a lease of immovable property concluded for temporary private use for a maximum of six consecutive months, the court of the state where the defendant is domiciled is also competent, provided the tenant is a natural person and both the owner and the tenant are domiciled in the same state.
For an owner in Rotterdam letting to a tenant in Antwerp, that carve-out is irrelevant — they are not domiciled in the same state. For an owner in Amsterdam letting privately to a tenant in Utrecht for under six months, it may matter a great deal. It is a narrow provision, and it is exactly the kind of narrow provision that decides where a dispute is actually fought.
What we look at for a short-stay owner
- Who, in practice, will file each arrival — you, a local manager, or the tourist organisation under Article 100 — and whether that person can do it inside twelve hours while you are in Belgium.
- Whether the way you lend the flat is genuinely private or has quietly become a service, because the two sit under different regimes.
- The de-registration side, which is forgotten far more often than the registration side and carries the same twelve-hour clock.
- Whether the building's rules permit the frequency of turnover you are planning, before the neighbours raise it rather than after.
- What runs on the property between visits — the communal fee, water and waste, and electricity — which we set out in unpaid utility bills when buying property in Montenegro.
Whose side we are on, and how we are paid
Every other professional around a Montenegrin transaction is paid out of the transaction. The agent's commission depends on the sale completing. The developer's sales team belongs to the developer. The notary owes duties to the act, not to you. That is not a scandal — it is simply how those roles are funded, and it decides what each of them is able to tell you.
We take no commission from sellers, developers, agents or brokers. None, in any form, on any file. The fee you pay us is our only income from your matter, and it does not increase if you sign. That single fact is the whole difference: because our position does not move when the deal moves, "do not buy this one" costs us nothing to say.
What that looks like in the file, rather than in a slogan: we obtain the register extracts ourselves instead of accepting the copies handed over by the seller or the agent; we read the contract against your position rather than against completion; we put in writing when the answer is that the matter should not proceed; and where a defect can be cured, we tell you what it costs in time before you commit money.
One boundary we state plainly. We are lawyers, not licensed investment advisers. We do not give personal investment advice on financial instruments and we do not tell you whether an asset will make money. What we protect is your legal position — the title, the contract, the registration, the status, and the deadlines that decide all four.
How we open this file
Tell us how the flat will actually be used over a year: how many of your own trips, how many stays by family and friends, and whether anything will be let. We will tell you which filing duty attaches to each of those, who can discharge it inside the deadline while you are abroad, and where the line runs between lending and letting. If the honest answer is that the pattern you are planning does not work without someone on the ground, you will get that in writing.
