The Promise to Purchase and Sell (Promesa de Compraventa) in Panama.

The instrument behind most real estate deals in Panama

Ask any real estate lawyer in Panama which single document sees the most use, and the answer is rarely the final deed — it is the promesa de compraventa, the promise to purchase and sell. It is the standard instrument for reserving a pre-construction condominium unit, and it is common practice even in resale transactions between two individuals, precisely because it lets both sides lock in price and terms while the remaining steps — financing, title verification, or, for new construction, the building's completion and individual titling — are worked out.

What it actually does: an obligation to sell and buy, not a transfer

A promesa de compraventa is fundamentally different from a deed of sale, and confusing the two is one of the most consequential mistakes a buyer can make. The promise obligates the seller to sell and, typically, the buyer to buy, under the price and terms fixed in the document, at a future point once specified conditions are met. It does not, by itself, transfer ownership — that only happens when the parties later execute a notarized deed of sale and register it at the Public Registry.

Why pre-construction sales depend on it

For a condominium still under construction, this distinction is not a technicality — it is structurally necessary. A specific unit cannot be individually titled and transferred until the building exists, is legally subdivided under the horizontal property regime, and each unit receives its own registered finca number. The promesa de compraventa lets a developer sell units and collect deposits years before that titling is possible, while giving the buyer a binding, enforceable claim to the specific unit at the agreed price — protecting against the developer selling the same unit twice, or raising the price before delivery.

What a well-drafted promise actually needs to specify

The promesa de compraventa's enforceability, and how well it actually protects you, depends heavily on drafting quality, since Panamanian law leaves much of the detail to the parties' agreement rather than filling gaps automatically:

• Precise identification of the specific unit or property, including plans, square footage, and finishes where relevant to a pre-construction sale.
• The full price and payment schedule, including the initial deposit (commonly called arras or reserva) and any installments due before closing.
• The closing date or triggering condition — for pre-construction, typically tied to the issuance of the occupancy permit or individual titling of the unit.
• Default consequences for each side, spelled out explicitly rather than left to general law: what the buyer forfeits if they walk away, and what the seller owes if they do not deliver as promised.
• Conditions that allow either party to exit without penalty, such as a financing contingency for the buyer or a construction-delay threshold for the seller.

The earnest money question: what happens to your deposit

This is where buyers are most exposed if the agreement is silent or vague. A common — but not automatic — structure ties consequences to fault: if the seller defaults, they return the deposit, often doubled as a penalty; if the buyer defaults, they forfeit the deposit to the seller. This structure is not imposed by default Panamanian law; it exists because the parties wrote it into the contract. A promesa de compraventa that does not address this explicitly leaves both sides exposed to a dispute over what "should" happen, resolved only through the general breach-of-contract remedies covered in our guide to breach of contract in Panama — a considerably more expensive and uncertain path than a clear clause would have been.

Due diligence still matters before you sign

Because the promise obligates you to buy at a future date, the due diligence that should precede any real estate purchase — confirming the developer's legal standing, the project's permits, and, for resale properties, that the seller holds clean, registered title — should happen before signing the promesa, not after. Our guide to the legal risks of buying property in Panama covers the title-verification side in detail.

Getting it right before the deposit is at risk

A promesa de compraventa is negotiated and signed under time pressure more often than almost any other Panamanian contract — units sell out, prices are held only briefly, developers push for a quick signature. That pressure is exactly why the document deserves a careful legal review before signing, not after a dispute arises over a deposit.
