Rising market prices alone do not give a seller the right to rewrite an agreed property price. If the preliminary sale and purchase agreement specifies a fixed amount without a clear adjustment mechanism, the seller can propose a change but cannot impose it without the buyer’s consent. An unjustified refusal to sign the final agreement may result in liability for contractual penalties and proven losses, as well as repayment of the buyer's advance.
Equally, buyers should not assume they will automatically receive the entire difference between the old and new prices. Lietuvos Aukščiausiasis Teismas (the Supreme Court of Lithuania, or LAT) emphasises proof of loss, an appropriate calculation method and the compensatory purpose of civil liability. The outcome therefore depends on the agreement's wording, each party's conduct, deadlines and the evidence retained.
What does signing a preliminary agreement actually mean?
Under Article 6.165 of Lithuania's Civil Code, a preliminary agreement is a written undertaking to enter into a final contract in future on agreed terms. It does not itself complete the notarial transfer of property, but it creates real obligations. A party that unjustifiably avoids or refuses to complete the transaction must compensate the other for the resulting losses.
Price is one of the central terms. A lawyer's published commentary in 2026 makes the practical point that a fixed final price cannot be increased unilaterally where no adjustment right has been agreed. If the contract does allow indexation, examine the formula: what triggers it, which data are used, what limits apply and what happens if the buyer disagrees.
What did the case about an apartment sold to another buyer at a higher price establish?
In a case considered by the Supreme Court in 2024, the parties had already agreed one increase, taking the apartment price to €70,670. The seller then proposed €85,140, advertised the apartment for €99,999 and, after the buyer refused, sold it to someone else for €95,000. The buyer was refunded their €15,740 advance and was paid €2,000 in compensation. Lower courts awarded the €24,330 price difference, but the Supreme Court overturned those decisions and sent the case back for reconsideration because the calculation method had not been adequately justified. The facts are set out in the court's official account of case e3K-3-117-781/2024.
In 2025, an expanded Supreme Court panel clarified the approach. Where a clear preliminary agreement records the most advanced stage of negotiations, losses following its breach may be assessed through direct losses, loss of opportunity, or subjective or objective calculation methods. These last two approaches concern an actual replacement transaction or the relevant market-price difference. A later sale at a higher price can help establish the market price at the time of the breach. Treating the seller's gain as the buyer's loss, however, remains exceptional. The court's account of its ruling of 22 December 2025 explains this distinction.
| Possible consequence | What still needs to be established |
|---|---|
| Return of the advance | What was paid, when and for what purpose, and what the agreement provides |
| A contractual penalty or other agreed damages | Whether the provision was clearly agreed, is proportionate and applies to this breach |
| Direct losses | Actual valuation, financing, legal or other reasonable expenses and their connection to the breach |
| A price difference | An appropriate method, the market price when the breach occurred or a replacement transaction |
| The seller's gain | Exceptional circumstances; this is not automatic compensation for the buyer |
What buyers should do: avoid gaps in the evidence
- Check the deadline. When must the final agreement be signed, and how can the deadline be extended?
- Respond in writing. Ask which specific clause permits the price change, and confirm that you remain ready to perform on the agreed terms.
- Take care before signing an amendment. An agreed and signed price change will normally become the parties' new arrangement.
- Record the facts. Keep correspondence, payment records, listing copies, the valuation, bank responses and evidence of reasonable expenses.
- Limit your losses. Do not reject reasonable alternatives simply to increase a future claim; the court also considers the injured party's conduct.
- Seek advice before the deadline. The wording of a claim and the available remedy depend on whether this is an ordinary preliminary agreement, a consumer contract or an agreement for a home yet to be built.
If you are buying with a mortgage, also consider what happens when you have paid an advance but the bank has not approved financing, or when the mortgage valuation is below the agreed price. These are distinct risks. A seller's wish to make more money is different from a properly drafted financing condition.
What should a seller or developer consider?
A more profitable sale to another buyer can become an expensive dispute. Before proposing a new price, read the clauses on amendments, force majeure, deadlines, contractual penalties and notices as well as the price clause. Higher costs or a better offer from another buyer do not, by themselves, allow you to disregard an earlier agreement. If it has become impossible to fulfil the agreement, explain the grounds openly and negotiate a written agreement rather than issue an ultimatum.
When a developer contracts with a consumer, the fairness of standard terms also matters. VVTAT (Lithuania's State Consumer Rights Protection Authority) has found asymmetric terms in a preliminary property agreement unfair where the consequences of withdrawal differed substantially for seller and buyer. Its guidance for buyers also recommends recording whether the price can change and agreeing each party's liability in advance.
Seven provisions that reduce the risk of a price dispute
- The exact property, included fittings, floor area and any permitted variation in floor area.
- The total price, price per square metre and a clear explanation of how they relate.
- An exhaustive list of grounds for adjustment, with the formula, limit and required evidence.
- The deadline for the final agreement, extension procedure and each party's preparatory steps.
- The purpose of the advance, payment schedule, refund provisions and separate contractual penalties.
- Conditions covering financing, valuation and obtaining documents.
- Balanced, proportionate consequences for a breach by either seller or buyer.
Sellers should establish a defensible price before accepting an advance. Start with pricing an apartment using completed sales and a realistic plan for achieving a higher price through proper preparation and presentation. Use the property sale documents checklist to prepare for the legal process, and disclose the property's condition accurately: a separate dispute over hidden defects can arise after completion.
An agreement for a home yet to be built may offer different remedies
An ordinary preliminary agreement generally cannot be enforced by compelling the sale itself; disputes usually concern losses and contractual penalties. Article 6.401 of the Civil Code establishes a special regime for purchasing a house or apartment that has not yet been built, and Supreme Court case law recognises broader buyer remedies in certain circumstances. A document titled “preliminary agreement” therefore does not, by itself, tell you what you can claim. The property, parties, funding arrangement, construction stage and substance of the agreement all need examination.
A rising market is a reason to negotiate carefully before signing. Afterwards, buyers should protect their rights calmly and methodically. Sellers considering a change of course need to weigh the higher price against the potential contractual liability and damage to their reputation.
Frequently asked questions
Can the seller raise the price after a preliminary agreement has been signed?
Generally, not unilaterally if the agreement fixes the final price and contains no clear adjustment mechanism. The seller may propose a change, but the buyer’s refusal does not itself remove the obligations already agreed.
Can the seller withdraw simply by returning the advance?
Not necessarily. Contractual penalties and the buyer’s proven losses also need to be considered. Repaying the advance does not itself remove potential liability for an unjustified refusal to enter into the final agreement.
Does the buyer automatically receive the whole price difference?
No. The existence and amount of the loss, and its connection with the breach, must be proved. The Supreme Court of Lithuania recognises several calculation methods. A later, higher sale price may be evidence of market value, but it is not automatically the amount awarded to the buyer.
Can a preliminary agreement force the seller to sell?
An ordinary preliminary agreement generally cannot be enforced by compelling completion; damages are the usual remedy. However, an agreement for a house or apartment yet to be built may fall under the special regime in Article 6.401 of the Civil Code. A lawyer should assess the actual document.
What is the difference between an advance, a contractual penalty and rankpinigiai?
An advance is a payment towards the purchase price. A contractual penalty or other agreed damages provision specifies consequences for breach. Rankpinigiai is a distinct Lithuanian Civil Code concept, sometimes loosely translated as earnest money. Using that label casually does not determine the legal effect: the full agreement and applicable Code rules matter.
What should a buyer do after receiving a demand for more money?
Take time before signing an amendment, ask in writing for the contractual basis of the proposed increase, retain correspondence and confirm that you are ready to proceed on the agreed terms. Obtain individual legal advice before the deadline for the final agreement.
Is a developer’s standard clause always valid?
No. Consumer protection may apply when an individual buys a home for personal purposes from a business. A term that was not individually negotiated and significantly tilts the parties’ rights and obligations against the consumer may be unfair.
What evidence should I keep if a dispute arises?
Retain the signed agreement and amendments, payment statements, every proposed price change, dated copies of listings, financing and valuation records, evidence of your search for an alternative home and invoices for reasonable expenses. A lawyer or court assesses their significance in the particular case.
