What Is a Promise of Sale (Konvenju)?

A Promise of Sale agreement, commonly referred to in Malta as a Konvenju, is one of the most important stages in a property transaction. It is the formal point at which a buyer and seller commit to the sale of a property under agreed terms, prior to the final deed of sale being signed. In the Maltese property market, the Konvenju plays a central role in protecting both parties while allowing time for legal, financial and property compliance checks to be completed.

At its core, a Promise of Sale agreement (Konvenju) is a legally binding preliminary contract in which a seller agrees to sell their property to a willing buyer at an agreed-upon purchase price. While ownership of the property does not transfer at this stage, the agreement creates enforceable obligations on both sides.

The importance of a Promise to Sell agreement lies in the security it offers. It effectively reserves the property, sets out the conditions under which the sale will proceed and establishes a clear framework leading up to the final contract. Without a properly structured and registered Promise of Sale agreement, both parties are exposed to unnecessary legal and financial risk.

Legal Basis and Formal Requirements of a Promise of Sale Agreement in Malta

The Promise of Sale agreement in Malta is governed by Maltese civil law and established conveyancing practice. For a Konvenju to be valid and enforceable, certain formal requirements must be met, and failure to observe these requirements can render the agreement void.

One of the most critical legal requirements is that the Promise of Sale must be made in writing. Oral agreements relating to the sale of immovable property have no legal effect under Maltese law. The written agreement must clearly identify the buyer and seller, the property being sold and the essential terms of the transaction.

Registration with the Inland Revenue Department is another mandatory step. Once the Promise of Sale agreement is signed, it must be registered within the prescribed timeframe, typically within 21 days. At the point of registration, a provisional payment of stamp duty is made, usually amounting to 20% of the total stamp duty due on the final transfer. Without proper registration, the Konvenju loses its legal force and cannot be relied upon in court.

In practice, most Promise of Sale agreements in Malta are executed as a public deed before a notary. While private agreements can exist, a notarial Konvenju is by far the most common and offers the highest level of legal certainty. The involvement of a notary ensures that the agreement complies with legal requirements and that the parties understand the obligations they are undertaking.

The duration of a Promise of Sale agreement is typically limited. Most agreements are valid for a period of three to six months, although the parties are free to agree on a shorter or longer term depending on the complexity of the transaction. This timeframe allows sufficient opportunity for due diligence, financing arrangements and preparation of the final deed of sale.

Key Elements of a Promise of Sale in Malta

A well drafted Promise of Sale agreement sets out all the essential terms that will later be reflected in the final deed of sale. Each element plays a role in defining the rights and obligations of the buyer and seller during the interim period and should include;

Price and Payment Terms – The Promise of Sale agreement must clearly state the total price, the currency and how the payment will be structured. This typically includes confirmation that the balance of the price will be paid upon signing of the final deed of sale. Any special payment arrangements, such as staged payments or retention of a portion of the price pending completion of works, should be explicitly included.

Deposit and Provisional Tax Payment - Most Promise of Sale agreements in Malta require the buyer to pay a deposit upon signing. This is commonly set at around 10% of the purchase price. In addition to the deposit, the buyer is required to pay a provisional amount of stamp duty when the Konvenju is registered. This is usually 20% of the total stamp duty due. These payments have important legal implications and should be clearly addressed in the agreement, including how the deposit is to be held and under what circumstances it may be forfeited or refunded.

Conditions and Clauses - Common conditions include the agreement being subject to the buyer obtaining bank financing, the issue of planning permits or the verification of specific property details. These conditions protect the buyer by allowing withdrawal from the agreement if essential requirements are not met within the stipulated timeframe. The wording of conditions must be precise, as vague or poorly drafted clauses can limit their enforceability.

Property Description and Title Status - The Promise of Sale agreement must clearly describe the property, including its location, boundaries, and any rights attached to it, such as rights of access or use of shared spaces. It should also outline the current title status, whether the property is freehold or subject to ground rent. Any known burdens, servitudes or encumbrances must also be disclosed.

What Happens After Signing a Promise of Sale Agreement

Once the Promise of Sale agreement has been signed and registered, the transaction enters a critical interim phase. This period is dedicated to verification, preparation and fulfilment of the agreed conditions including;

Notarial Searches and Due Diligence - A series of notarial searches are carried out to confirm that the seller has a valid and marketable title to the property. These searches check for mortgages, hypothecs, liens and other registered burdens. The notary will also verify compliance with planning and building regulations and ensure that any required permits are in place. If issues are identified, they must be resolved before the final deed of sale can proceed.

Financing Arrangements - For buyers who require a home loan, the Konvenju period provides the time needed to secure mortgage approval. Banks in Malta typically require a signed Promise of Sale agreement before issuing a formal sanction letter. If financing is included as a condition in the agreement, the buyer must act within the specified timeframe to obtain approval.

Preparation of the Final Contract - Once all conditions are satisfied and the notarial searches are completed, the notary will prepare the final deed of sale. A date is agreed for the signing, at which point the balance of the purchase price and the remaining stamp duty are paid, and ownership is formally transferred.

Legal Implications and Enforcement of a Promise of Sale Agreement

A Promise of Sale agreement is a legally binding contract which both the buyer and the seller are expected to adhere to. If one party fails to honour the Konvenju without a valid legal reason, the other party may seek enforcement through the courts. This can include compelling the completion of the sale or claiming damages for losses suffered.

If conditions are not fulfilled or disputes arise, the affected party must act before the Konvenju expires. Allowing the agreement to lapse without taking action can result in the loss of legal rights. A Promise of Sale agreement that is not properly registered or does not meet statutory requirements may be declared null, leaving both parties without contractual protection.

Practical Tips for Buyers and Sellers

In practice, most issues linked to a Promise of Sale do not arise from complex legal defects, but from misaligned expectations between the parties. The Konvenju should therefore be approached as a risk management tool rather than a procedural formality. Buyers should treat the Promise of Sale period as an active time, not a waiting phase. Mortgage applications, technical inspections and document requests should be initiated immediately after signing, as delays during this window can weaken a buyer’s position if deadlines are missed.

Sellers benefit from preparing documentation in advance. Providing updated permits, plans and title information early reduces the likelihood of extensions being requested and signals readiness to proceed, which can be particularly important in competitive property transactions. Both parties should be mindful that once signed, flexibility is limited. Variations, extensions or waivers typically require written agreement and can introduce uncertainty or negotiation pressure. Entering a Promise of Sale agreement with a clear understanding of timelines and obligations helps prevent avoidable renegotiation.

The Promise of Sale agreement remains a cornerstone of property transactions in Malta. When properly drafted and executed, it provides clarity, security and a structured path to completion, making it an indispensable part of buying or selling property on the island.
