Foreign buyers treat the promesa like a formality — a handshake in legalese on the way to the "real" signing. Colombian law disagrees. The promesa de compraventa is a binding contract with financial penalties attached, and every term you accept in it is a term you've already lost the ability to negotiate. The escritura just executes what the promesa decided.
Nine clauses deserve a fight — or at least a hard read — before your signature goes anywhere near it.
1. Arras: the penalty percentage
The arras is the deposit-slash-penalty at the heart of the promesa: walk away as the buyer and you typically forfeit it; if the seller walks, they typically must return it doubled. Market practice runs around 10% of the price. Sellers (especially of foreigner-targeted listings) push 20% or more — which converts every later dispute into hostage negotiation, because walking away now costs you a fifth of the purchase price. Fight anything above 10%; on larger purchases, negotiate lower.
2. Arras: the asymmetry trap
Worse than a big penalty is an unequal one. Read for the mirror: if you breach, you lose the arras — and if the seller breaches, they return it doubled. Promesas drafted by seller's counsel sometimes soften or delete the seller's side ("returns the deposit without penalty," or with vague cure periods only they enjoy). A penalty regime that only points at you isn't a deposit — it's a leash. Insist on symmetry.
3. Deadlines with teeth pointed only at you
Every promesa fixes the escritura date, place, and notaría. The traps: dates that are automatic breaches for you but "reasonable extensions" for the seller; escritura dates set too tight for your realities (wire timing, apostilled POA transit if buying remotely, bank or fiducia processing); and no defined mechanism for extending by mutual agreement. Build in the time you actually need plus margin — penalty clocks don't care that your apostille sat in a queue.
4. Payment schedules that outrun protection
The dangerous pattern: large payments due before the escritura, secured by nothing but the promesa itself. The more of the price that moves pre-deed, the more you're an unsecured creditor of a stranger. Keep pre-escritura payments to the arras; the balance moves at signing, when ownership moves with it. (Pre-construction is its own structure with fiducia protections — different article, different rules. For a resale, "50% now, 50% at deed" is a red flag with a payment plan attached.)
5. No condition on a clean title
Your promesa must make the seller's obligations conditional on the property being delivered free of liens, embargoes, occupants, and undisclosed encumbrances — with your exit (arras returned, no penalty) if the condition fails. Here's why it matters: you pull a fresh certificado before closing and find a surprise — an embargo filed last month, an unmentioned hipoteca. With the clause, that's the seller's problem to cure or your clean exit. Without it, you're the one in breach for refusing to close. This clause is non-negotiable, and its absence from a draft tells you who the drafter was protecting.
6. "As-is" doing more work than it should
Physical-condition language deserves a look: promesas that disclaim everything — hidden defects (vicios ocultos), area discrepancies, non-functioning systems — strip warranties Colombian law would otherwise give you. Ensure the promesa states the area per the registered cabida, lists what conveys (that furniture package you negotiated exists only if it's written here, with an inventory annex), and doesn't waive hidden-defect claims.
7. The paz y salvo gap
Unpaid administración fees and predial follow the property, not the seller. The promesa must obligate the seller to deliver paz y salvos — clearance certificates from the building administration and for property tax — at escritura, and address any voted-but-unbilled cuota extraordinaria (that special assessment for the new elevator gets paid by… whoever the promesa says). Silence here means you inherit the building's opinion of the seller's debts.
8. Under-declaration written into the deal
Some promesas openly split the price: one number for the escritura, another paid "outside." Beyond the legality problem, you're signing evidence of the scheme — and as covered in the threshold guide, an under-declared deed can kill visa eligibility and inflates your tax bill at exit. If the promesa's price and the deed's price aren't the same number, stop.
9. Dispute clauses you can't actually use
Check who resolves conflicts and where. An arbitration clause naming an expensive tribunal, or jurisdiction provisions that make small disputes uneconomical to pursue, quietly deletes your remedies. For most purchases, ordinary Colombian courts in the property's city are the sane default — exotic dispute machinery in a residential promesa serves whoever expects to breach.
Who drafted the document? A promesa produced by the seller's lawyer or the listing agency is an opening offer wearing contract formatting — every default in it leans their way, which is fair enough if you treat it that way. The mistake isn't receiving a seller-drafted promesa; it's signing one unreviewed because "it looked standard." Standard for whom is the whole question. Diligence findings are also negotiating leverage: a promesa revision is where the repricing conversation happens.
The bottom line
None of this requires paranoia — it requires sequence. Certificado and reglamento reviewed first, promesa negotiated second, arras moved third, escritura last. The buyers who get hurt ran it backwards: deposit wired to "hold the unit," promesa signed as received, problems discovered when the only exits left were expensive ones. The full process guide shows where each document lands on the timeline; this article is the reason the promesa step gets its own week.
