What is the Promise of Sale (Konvenju) and is it legally binding?

What the Konvenju is, in Dr. Laferla's words

Notary Dr. Michael Laferla describes it plainly: "The Promise of Sale, in Maltese we call it Konvenju, is that document that is drafted, that is created by the notary to crystallise what the parties have agreed to, and it's registered with the Commissioner of Inland Revenue and therefore it is a binding agreement."

The Konvenju is the legal vehicle that turns a verbal agreement into a binding commitment. Buyer and seller agree on a price, the terms, and the conditions attached to the sale. The notary takes that agreement and converts it into a written document — and the act of registering that document with the Inland Revenue gives it legal force.

The name comes from the Italian convenzione — convention or agreement. In Maltese property practice, it's the document that opens the formal phase of the transaction.

What makes the Konvenju binding

Dr. Laferla identifies the key mechanism: registration with the Commissioner of Inland Revenue. Under Maltese law, a Konvenju must be registered with the Inland Revenue Department within 21 days of signing. This registration is both a tax-administration step (the buyer pays 1% provisional stamp duty on the property's value at this point) and the legal moment that gives the document its binding character.

A few further legal foundations underpin the Konvenju's enforceability:

• It must be in writing. Under the Maltese Civil Code, promises to sell immovable property must be in writing to have legal effect. Verbal or informal agreements to sell property are not enforceable under Maltese law.
• It must satisfy notarial formalities. Where the Konvenju is contained in a public deed, it must meet the requirements of the Notarial Profession and Notarial Archives Act, Chapter 55 of the Laws of Malta.
• It must be registered. The 21-day registration window with the Commissioner of Inland Revenue is what activates the document's legal force, alongside collecting the provisional stamp duty.

Once these requirements are satisfied, the Konvenju binds both parties. Neither buyer nor seller can walk away unilaterally without consequence.

What the Konvenju commits both parties to

Once signed and registered, the Konvenju creates specific obligations:

The seller commits to:

• Selling the property to the named buyer at the agreed price
• Not accepting other offers or selling to anyone else during the Konvenju's validity period
• Completing the sale within the agreed timeframe (typically 6 to 8 months, extendable by agreement)
• Providing the necessary documents and access for the notary's due diligence work

The buyer commits to:

• Buying the property at the agreed price (subject to any conditions written into the Konvenju)
• Paying the deposit (typically 10% of the purchase price), generally held by the notary in their client account
• Paying the 1% provisional stamp duty within 21 days
• Completing the purchase by the final deed date

Where the deposit is held

When the buyer pays the deposit at the Konvenju, the standard practice is that the notary holds it in their client account — a regulated arrangement where the funds are kept securely until the final deed is signed and ownership transfers. This protects the buyer: if anything goes wrong with the transaction, the funds are not in the seller's possession.

Dr. Laferla notes one practical exception: in some cases, particularly with developers, the seller may request that the deposit be paid directly to them, often in exchange for a discount on the purchase price. This is a contractual choice the buyer can make, but it removes the protective benefit of having the funds held in the notary's client account. If the sale subsequently falls through for any reason, recovering funds paid directly to a seller is more difficult than recovering funds held by the notary.

What happens if either party refuses to complete the sale

Maltese law sets out two different regimes depending on how the deposit at the Konvenju is structured. Both are statutorily valid; the standard modern practice falls under the first.

Standard case — deposit on account of the price (Civil Code Article 1357)

This is the regime Dr. Laferla describes, and it's the standard form for modern Maltese property transactions. Under Article 1357 of the Civil Code (Chapter 16 of the Laws of Malta), when a Konvenju is properly accepted and the deposit is paid on account of the final price, the promisor (seller) is obliged to carry out the sale. The seller cannot back out.

If the seller refuses to appear at the final deed of sale, the buyer's remedy is specific performance — compelling the sale through the courts. The procedure under Article 1357(2) is:

1. Before the Konvenju expires, the aggrieved party files a judicial letter demanding that the other party appear on the deed of sale.
2. If the defaulting party still refuses, the aggrieved party files a sworn application before the First Hall of the Civil Court within 30 days of the Konvenju's expiration, requesting forced execution.
3. The court can then order the sale to be carried out.

This 30-day deadline is hard. If the aggrieved party misses it, the Konvenju lapses and the deposit must be returned regardless of any contractual forfeiture clauses. The procedural discipline matters as much as the substantive right.

If specific performance is no longer possible (for example, if the seller has sold the property to someone else despite the Konvenju), the buyer's remedy under Article 1357(1) shifts to damages and interest.

Alternative — earnest money / kapparra (Civil Code Article 1359)

A different regime applies if the deposit at the Konvenju is paid as earnest (kapparra) rather than on account of the price. Under Article 1359 of the Civil Code:

• Either party may withdraw from the Konvenju at any time
• If the buyer withdraws, they forfeit the earnest to the seller
• If the seller withdraws, they must return double the earnest to the buyer

The kapparra regime is the older statutory form and is less common in modern Maltese property practice, but it remains legally valid. Whether a payment counts as kapparra or as deposit-on-account depends on how the Konvenju is drafted. A well-drafted Konvenju is explicit about which regime applies — the notary's role includes ensuring the document is clear on this point.

The practical takeaway

For most modern property transactions in Malta, the standard regime is deposit-on-account-of-price under Article 1357 — meaning the seller cannot legally back out, and the buyer has the right to enforce the sale through specific performance. The kapparra alternative exists for transactions structured under Article 1359, where the parties prefer to retain the option to recede with statutory consequences.

What happens if the buyer backs out

The situation is different on the buyer's side. If the buyer walks away without a valid contractual reason — meaning without invoking one of the conditions written into the Konvenju — they forfeit the deposit. The seller keeps it as compensation for having taken the property off the market.

What counts as a "valid contractual reason" depends on what was written into the Konvenju. The most common protective clause is "subject to bank loan approval" — if the buyer's mortgage application is refused, this clause allows them to withdraw and recover their deposit. Other common protective conditions include subject to clean title searches, subject to specific permits being in order, or subject to a particular condition the seller agreed to satisfy.

As with the seller-breach scenario, the seller's right to retain a forfeited deposit is not automatic. The seller must file a judicial letter before the Konvenju expires and a sworn application within 30 days of expiration, and obtain a court order confirming the buyer had no valid reason to refuse. Missing the procedural deadlines means the deposit must be returned regardless of contractual language.

The Konvenju's role in the overall transaction

The Konvenju sits between the verbal agreement and the final deed of sale. During its validity period (typically 6 to 8 months, with possible extensions by mutual agreement), several things happen in parallel:

1. The notary conducts due diligence — searching the Public Registry, verifying clean title, checking permits, confirming there are no debts or hypothecs attached to the property
2. The buyer arranges financing — if a bank loan is needed, this is when the formal application and approval process happens (the bank issues a sanction letter following the Konvenju)
3. Any conditions in the Konvenju are fulfilled — outstanding work the seller agreed to complete, permits to be obtained, etc.

If everything is in order at the end of the validity period, the parties sign the final deed of sale in front of the notary, and ownership formally transfers. If issues are found during due diligence, they're resolved before the final deed — or the Konvenju is terminated with consequences as defined in the document itself.
