The document in your inbox is headed Predugovor o kupoprodaji nepokretnosti. The agent has translated it as "preliminary contract" and described it as a formality — the paperwork that holds the apartment while the notary appointment is arranged. Sign it, transfer the deposit, and the real contract follows.
Half of that is right. A predugovor is a preliminary step, and it is not the instrument that makes you the owner. The other half is where foreign buyers lose money: it is a contract in its own right, it fixes the price and the deadlines, it decides what happens to your deposit, and — depending on one drafting decision the seller usually makes for you — it is worth either a court order compelling the seller to complete, or nothing at all.
This is the clause-level companion to our guide on the Montenegro reservation agreement and pre-SPA, which deals with the earlier, English-language reservation form. Here the subject is the document carrying the local name, and what to change in it before your signature goes on the page.
What a predugovor actually is
The Law on Obligations (Zakon o obligacionim odnosima, "ZOO", Official Gazette of Montenegro 47/08, 4/11, 22/17, 123/24) defines it in a single provision. Under Article 40(1), a predugovor is a contract by which a party assumes the obligation to conclude another, main contract later. That is its whole function: it does not transfer anything, it promises a future contract.
Two limits follow immediately.
Article 40(3) provides that a predugovor binds only if it contains the essential elements of the main contract. For a sale that means the property and the price. A document that identifies the unit loosely, or leaves the price to later agreement, is not a weaker predugovor — it may be no predugovor at all. Article 470(1) makes the same point about sale contracts generally: if the price is not determined and the contract does not contain sufficient data by which it could be determined, the contract has no legal effect.
That cuts in both directions, and buyers rarely see the second edge. A price-escalation clause that lets the developer adjust the figure by reference to something it controls does not merely expose you to a higher price; it can undermine the determinacy on which the document's binding force rests. If you want a predugovor that binds the seller, the price has to be pinned down.
The form question decides whether you have anything
Article 40(2) is the provision most often ignored in practice: the rules on the form of the main contract apply to the predugovor as well, where the prescribed form is a condition of the contract's validity.
For Montenegrin real estate it is. Article 61 ZOO requires a contract transferring ownership of immovable property, or establishing another real right in it, to be made in written form and certified in accordance with the regulations. Article 52(1)(6) of the Law on Notaries places transactions whose object is the transfer or acquisition of ownership or other real rights over immovable property in the notarial-record category, and Article 52(3) states that transactions in that category which are not made in the form of a notarial record produce no legal effect. Article 64(1) ZOO says the same in general terms.
Chain those together and the practical result is blunt: a predugovor for a Montenegrin property signed as a plain private document between the parties, or witnessed by an agency, will not support a claim to compel the seller to sign the main contract. That is the consistent reading of the statutes rather than a point settled by published Montenegrin case law, but it is how the risk should be priced. If you were told that "we will do the notary part later, this is just between us", you were told something that cannot be made true retrospectively.
There is a legitimate middle route. Article 51a of the Law on Notaries lets the parties have a private document confirmed by the notary, without a separate notarial record being drawn up; the confirmed document then has the character of a notarial record. That is how a document drafted by your own lawyer can be given the required form — worth knowing, because the version usually offered is the opposite one: the developer's template, presented at the notary as a finished text.
One more consequence of form that catches people later: under Article 60(2), a statutory form requirement extends to all subsequent amendments and supplements of the contract. Once the predugovor is in notarial form, an email agreeing a new completion date or a changed payment schedule does not amend it.
The six-month clock nobody mentions
Assume the form is right and the seller then refuses to proceed. Article 40(4) gives you the remedy: at the request of an interested party, the court will order the party refusing to conclude the main contract to do so within a deadline the court sets.
Article 40(5) attaches the timer. Conclusion of the main contract may be demanded within six months from the expiry of the deadline provided for its conclusion — or, where the document provides no deadline, from the day on which, by the nature of the transaction and the circumstances, the contract should have been concluded.
That is why a missing date is not a neutral omission. If the predugovor names a date for signing the main contract, your six months run from a fact anyone can read. If it does not, the start of your window becomes an argument about "the nature of the transaction and the circumstances" — with the party that drafted the document. A predugovor without a completion deadline is not flexible; it is vague in the seller's favour.
What a court order is actually worth
The remedy under Article 40(4) is more useful than foreign buyers assume, because it does not depend on the seller's continued cooperation. Article 251 of the Law on Enforcement and Security (Official Gazette of Montenegro 36/11, with amendments to 70/26) provides that an obligation to make a declaration of will contained in a decision having the character of an enforceable document is deemed fulfilled on the day that decision becomes final. Where fulfilment depends on an obligation of the creditor — paying the price — or on another condition, the debtor is deemed to have made the declaration when the creditor performs or the condition is met, proved by a public or duly certified document. And Article 84 of the Law on State Survey and Real Property Cadastre lists a final court decision among the bases for registration of rights, alongside an executive decision of a competent authority and a document about a legal transaction drawn up in accordance with the law.
The second half of the strategy is publicity. Once proceedings are on foot, Article 104 of the same law allows the dispute to be annotated (zabilježba spora) as an entry making visible that proceedings are pending which could affect the registered right. The effect is the point: a final judgment in the annotated dispute operates against persons who acquired rights over the property after the annotation was applied for, and Article 105 provides that when such a decision is executed, the register cancels the annotation together with every entry requested after the annotation request was filed. That is what stops a seller from selling the same unit to someone else while your case runs.
The seller's escape hatch
Article 40(6) closes the section: a predugovor does not bind if the circumstances have changed so much since its conclusion that it would not have been concluded had those circumstances existed at the time.
It sits alongside the general rule in Article 128, which lets a court modify or rescind a contract where unforeseeable events make performance excessively onerous — subject to Article 128(2), which denies that relief to a party who ought to have taken the circumstances into account when contracting, or could have avoided or overcome them. Neither provision licenses walking away from a deal that has merely become inconvenient. But Article 40(6) is what a seller reaches for in a rising market, which is a reason to keep the interval between predugovor and main contract short.
The clause checklist
| Clause | How developer paperwork usually reads | What Montenegrin law provides | What to change before signing |
|---|---|---|---|
| Form | Signed privately, notary "later" | Article 40(2) ZOO applies the main contract's form; Article 52 of the Law on Notaries makes that form mandatory and denies effect without it | Notarial record, or a private document confirmed under Article 51a |
| Property and price | Unit described by brochure reference; price "subject to adjustment" | Article 40(3) requires the essential elements; Article 470(1) denies effect where the price is undeterminable | Cadastre identifiers, fixed price, adjustment only by objective external index |
| Completion deadline | Silent, or "approximately" | Article 40(5) runs six months from the deadline for conclusion, or from when the contract should have been concluded | A calendar date for signing the main contract |
| Deposit | One clause headed "deposit", non-refundable | Kapara secures performance and does not buy an exit (Article 75(3)); an odustanica does (Articles 78 and 79) | Name the instrument, and state the consequences on both sides |
| Penalty for delay | Percentage payable by the buyer only | Article 277(3) prohibits a contractual penalty for monetary obligations; Article 281 allows the court to reduce an excessive penalty | Symmetrical remedies; delay in payment carries default interest, not a penalty |
| Withdrawal rights | Seller may rescind on notice; buyer may not | Articles 119 to 127 govern rescission for non-performance, and Article 126 bars rescission for an insignificant part | Mirror the grounds and the notice periods |
| Registration of your position | Not addressed | Article 100 of the cadastre law lets the holder of the right annotate an intended transfer; Article 102 limits it to 60 days | An obligation on the seller to file it, timed to your completion |
The money clauses are a separate discipline
The deposit paragraph is where most of the value sits, and Montenegrin law treats the three possible instruments very differently. Our guide to the kapara, avans and odustanica rules works through them; the short version is that kapara secures performance rather than buying a right to walk away (Article 75(3)), that the consequences on breach turn on who is responsible (Article 76), and that the word avans does not appear in the ZOO at all.
The penalty clause deserves its own look, because the usual drafting is not merely one-sided — it is often unenforceable as written. Article 277(3) provides that a contractual penalty cannot be agreed for monetary obligations, so a clause imposing a percentage penalty on you for paying an instalment late does not work as a contractual penalty; the seller's remedy for late payment of money is default interest under Article 284. Where a penalty is validly agreed for a non-monetary obligation, Article 281 lets the court reduce it at the debtor's request if it is excessive compared with the loss suffered.
Two interpretation rules apply to the seller's template as a whole. Article 98 ZOO provides that where a contract is concluded on pre-printed terms, or was otherwise prepared and proposed by one party, unclear provisions are interpreted in favour of the other party — the buyer, here. And where the seller operates through published general terms, Article 138 makes void those provisions that are contrary to the purpose of the contract or to good business practice, and allows the court to refuse to apply provisions that strip the other party of objections, cause it to lose rights or deadlines, or are otherwise unfair or excessively harsh.
Can you register the predugovor against the property?
Buyers ask this once they understand that ownership passes only on registration, and the honest answer has three parts.
First, there is no annotation of a preliminary contract. Article 98 of the cadastre law lists the facts recordable as a zabilježba — the list runs past thirty categories, from minority and guardianship to pending disputes, prohibitions on alienation, enforcement, fiduciary transfer, restitution and buildings erected without a permit — and a predugovor is not among them. The list does include an annotation of a notarial record with a designation of the legal transaction, but Article 83 sets the limit on what that achieves: where the law attaches no legal effect to a type of annotation, the annotation has the significance of public notice.
Second, there is a mechanism that does more, and it belongs to the seller. Under Article 100, the holder of the right may request an annotation that they intend to alienate the property or encumber it with a mortgage, in order to establish priority for the rights that will be registered on the basis of those transactions, with priority running from the moment the authority received the request. Article 101 permits it only where the register's current state would allow the entry and the signature on the request is certified. Article 102 gives it a short life: it loses effect after one year for a mortgage, and after 60 days in all other cases. Used deliberately — filed close to your completion, not months before — it is the closest thing to a reservation the register offers.
Third, the general priority rule sits behind all of this. Article 12 provides that entries are made according to the chronological order in which applications are filed, and that the legal effect of registration towards third parties begins from the moment the application is submitted to the authority — which is also why the certified folio you relied on should be recent. Our note on reading the list nepokretnosti covers what to check in it.
Before you sign
The predugovor stage is the last point at which changing a clause costs nothing but a conversation. Before your signature goes on the document, have your own adviser confirm in writing: that the form is right and how it will be achieved; that the property and price are specified to the standard Article 40(3) requires; that a date for the main contract is stated; that the deposit clause names its instrument and states both sides' consequences; that the remedies are symmetrical; and that the folio has been pulled recently enough to mean something. What happens at the notary afterwards is a separate discipline, described in our note on what the notary verifies and what they do not, and the full sequence is set out in our overview of the Montenegro property purchase process.
If a predugovor is sitting in your inbox with a deadline attached to it, send us the draft and the current folio before you sign rather than after. We act for the buyer alone, taking no instructions from developers or agencies — which is the entire point, because the document you have been given was drafted by someone acting for the other side. Our Montenegro lawyer team reads the clauses against the ZOO while they can still be changed.
