The questions a foreign buyer asks before completion are about the title. The questions asked afterwards are different: the terrace turns out to be built over the boundary, a neighbour produces a right of way nobody mentioned, the planning file shows a restriction the agent did not raise, or the price paid looks indefensible once comparable sales appear.
Montenegrin law answers those questions through two separate regimes with different triggers and different clocks, and the clocks are short. The shortest is eight days. The one most buyers assume they have — a general right to go back to the seller when something emerges — expires six months after delivery unless a specific provision applies.

Two regimes, not one
A material defect concerns the condition of the thing. A legal defect concerns somebody else's rights over it. They are governed by different articles, they start running at different moments, and a claim brought under the wrong one fails on the clock rather than on the merits.
Article 486 sets the material-defect standard: the seller is liable for material defects the thing had at the moment risk passed to the buyer, irrespective of whether the seller knew of them. It is also liable for defects appearing after risk passed where they result from a cause existing before. A trivial material defect is disregarded.
Article 487 defines when a material defect exists, and the list is wider than "something is broken". A defect exists where the thing lacks the properties needed for its ordinary use or for trade; lacks the properties needed for the particular use the buyer acquires it for, where that use was known or ought to have been known to the seller; lacks properties expressly or tacitly agreed or prescribed; does not conform to a sample or model; or lacks properties that other things of the same kind have and that the buyer could reasonably expect given the nature of the thing, taking into account in particular public statements by the seller, the producer and their representatives — advertising, labelling and the like. Improper installation is included where installation formed part of the contract, as is improper installation resulting from defective instructions.
That fifth limb is the one that reaches marketing material. A brochure describing a sea view, a completion standard or a shared facility is a public statement about the properties of the thing, and Article 487(2) removes it from account only where the seller neither knew nor ought to have known of the statement, or the statement was corrected before conclusion, or it did not influence the buyer's decision to contract.
The clocks on a material defect
| Situation | Deadline | Provision |
|---|---|---|
| Visible defect, ordinary contract | Inspect as soon as ordinarily possible; notify within 8 days | Art. 489(1) |
| Visible defect, commercial contract | Without delay | Art. 489(1) |
| Inspection carried out with both parties present | Objections raised immediately | Art. 489(2) |
| Consumer contract | No duty to inspect; notify immediately on becoming aware, at the latest within 6 months of discovering the defect | Art. 489(4) |
| Hidden defect | 8 days from the day of discovery; commercial contracts, without delay | Art. 490(1) |
| Outer limit on the seller's liability | Seller not liable for defects appearing after 6 months from delivery, unless a longer period is agreed | Art. 490(2) |
| After repair, replacement or part exchange | The Article 489 and 490 periods run again from delivery of the repaired or replacement item | Art. 491 |
| Extinction of the rights of a buyer who notified in time | 1 year from the day the notice was sent to the seller, unless the seller's fraud prevented their use | Art. 508(1) |
One line in that table needs a qualification before it is relied on. Article 489(4) applies to consumer contracts, and whether a particular purchase is one is decided by the consumer protection legislation rather than by the Obligations Act — it turns on the character of the counterparty. A purchase from a private individual selling their own property will not usually answer that description, which leaves the eight-day rule in Article 489(1) as the operative one. The classification is worth settling early, because the difference between eight days and six months is the whole claim.
Two further features of the table decide most real disputes.
The first is Article 490(2). A six-month outer limit, running from delivery rather than from discovery, is short for immovable property, where seasonal defects — damp, drainage, heating, roof performance — commonly announce themselves in the first winter after a summer completion. The provision allows a longer period to be agreed, and the sale contract is where that is done or not done.
The second is Article 508(2). Where the buyer notified in time but the year has run, and the price has not yet been paid, the buyer may still raise price reduction or damages as a defence to the seller's claim for the price. The right survives as a shield after it has expired as a sword — which is one reason a retention held back to completion of a snagging list is not merely commercial comfort.
Article 493, which suspends all of it
The provision that decides the outcome of most post-completion disputes is short enough to state whole.
Article 493 provides that the buyer does not lose the right to rely on a defect even where it failed to inspect the thing without delay, or failed to notify the seller within the prescribed period, and even where the defect appeared only after six months from delivery — where that defect was known to the seller or could not have remained unknown to it, or where the seller acknowledged the defect.
Every deadline in the table above is therefore conditional on the seller's innocence. A seller who knew of the damp, the unpermitted extension or the encroaching terrace and said nothing cannot rely on the eight days or the six months. The practical consequence is that a post-completion dispute in Montenegro usually turns on what the seller knew and when, rather than on when the buyer complained — and that documents from the seller's own file, the construction record and the neighbours are the material worth obtaining early.
Article 492 governs the notice itself, and it is generous on delivery. The buyer must describe the defect closely and invite the seller to inspect the thing. Where a notice sent in time by registered letter, telegram or another reliable means arrives late or does not arrive at all, the buyer is treated as having performed the duty to notify. Sending is what counts, provided the channel is reliable and provable.
Contracting out, and where it fails
Article 494(1) permits the parties to limit or wholly exclude the seller's liability for material defects. Montenegrin practice makes use of this, and an "as seen" clause in a sale contract is not decorative.
Article 494(2) voids that clause in two situations: where the defect was known to the seller and it did not inform the buyer, and where the seller imposed the clause using a special monopoly position. Article 494(3) adds that a buyer who has waived the right to rescind for defect retains the other remedies — price reduction and damages survive a waiver aimed only at rescission.
When somebody else has a right over the property
The legal-defect regime runs on its own logic.
Article 516(1) makes the seller liable where a third-party right exists that excludes, reduces or limits the buyer's right, where the buyer was not informed of it and did not consent to take the thing burdened by it. Disclosure and consent, not registration, are the operative concepts.
Article 517 puts the first move on the buyer: when a third party asserts a right, the buyer must notify the seller — unless the seller already knows — and call on it to free the thing of that right or claim within a reasonable period.
Article 518 sets out what follows if the seller does not:
- where the thing is taken from the buyer, the contract is rescinded by operation of law;
- where the buyer's right is reduced or limited, the buyer may choose between rescission and a proportionate reduction of the price;
- where the seller fails to free the thing within a reasonable period, the buyer may rescind if the contract's purpose cannot be achieved;
- in every case the buyer has the right to compensation for the damage suffered — except that under Article 518(4), a buyer who at conclusion knew of the possibility of dispossession or limitation has no damages claim if it materialises, though it keeps the right to restitution or reduction of the price.
Article 519 covers the buyer who litigates with the third party without telling the seller and loses: it may still invoke the seller's liability unless the seller proves it had the means to defeat the third party's claim. Article 520 allows the buyer to invoke liability where, without notice and without litigation, it recognised an obviously well-founded third-party right — and permits the seller to discharge itself, where the buyer paid the third party to abandon an obvious right, by reimbursing that sum and the damage suffered.
The provision that reaches planning and public law
Article 523 is the one least often quoted and most often relevant to Montenegrin land.
The seller is liable also for special limitations of a public-law nature that were not known to the buyer, where the seller knew of them, or knew that they could be expected, and did not disclose them to the buyer.
That covers the territory where Montenegrin purchases most often go wrong after completion: a planning designation that prevents the intended build, a restriction arising from proximity to protected land, a pending measure the seller was aware of. It is not a warranty of clean planning status — the seller's knowledge or expectation is the trigger — but it is a route that does not depend on anything appearing in the cadastre.
Article 524 sets the clock: the buyer's right on the basis of legal defects extinguishes one year from learning of the third party's right. Where the third party commenced proceedings before that year expired and the buyer called the seller to intervene in them, the right extinguishes only six months after the proceedings are finally concluded. Calling the seller into the litigation is therefore not merely tactical; it is what preserves the claim.
Article 522 mirrors Article 494 on the legal side: liability for legal defects may be limited or excluded by contract, but the clause is void where at the time of conclusion the seller knew, or could not have been unaware, of a defect in its right.
The price itself, and the sales where none of this applies
Article 134 provides a separate remedy aimed at the bargain rather than the thing. Where at the time of conclusion there was an obvious disproportion between the parties' obligations, the injured party may seek annulment of the contract if it did not know and was not obliged to know the true value. The right lapses one year from conclusion. An advance waiver of the right has no legal effect. Annulment cannot be sought if the disproportion no longer exists when the claim is filed, and the contract survives if the other party offers to make the difference up to the true value.
Article 134(6) then removes the remedy entirely from commercial contracts, aleatory contracts, public sales, settlements, and cases where a higher price was given for special reasons. A company buying from a company cannot use it; nor can anyone buying at a public sale.
That exclusion runs alongside Article 495, which states the position in one line: the owner whose thing is sold at a compulsory public sale is not liable for defects of the thing.
Read together, the two provisions describe an enforcement purchase accurately. A buyer at a Montenegrin enforcement auction has no material-defect claim against the dispossessed owner and no remedy for a disproportionate price — which is the other half of the picture we set out in what survives an enforcement sale. The discount at auction is not only a discount for the encumbrances that pass with the land; it is also the price of losing the warranty regime that a private purchase carries.
What this means before signing
Three of these provisions are decided by the contract rather than by the statute, and all three are decided before completion rather than after.
Article 490(2)'s six-month outer limit can be extended by agreement, and for property bought outside the season in which its defects tend to appear, that is the provision most directly on point. Article 494(1) permits an exclusion of liability, so its absence — or its presence — is a negotiated outcome rather than a default. And Article 516(1) turns on disclosure and consent, which means that what the buyer was told, and what the buyer recorded having been told, defines the boundary of the seller's liability for third-party rights.
After completion, the sequence is narrower: notify in writing, describe the defect closely, invite inspection, send it by a provable channel, and treat the one-year period in Article 508(1) as running from the date of that notice rather than from any later negotiation.
