If someone owes you money in Argentina, this guide explains how to formally demand payment, what happens if it’s ignored, and the real legal deadlines and options involved, in plain language, verified against Argentine law.
Share the details, the amount, how long it’s been overdue, and whether there’s a contract, invoice, cheque, or promissory note behind it, and we’ll tell you the fastest realistic path to getting paid.
Debt collection in Argentina almost always starts the same way: a formal demand for payment sent as a carta documento, Argentina’s certified demand letter. It puts the debtor formally on notice, states the amount owed and the deadline to pay, and creates provable evidence that the demand was made and delivered. For the full mechanics of how a carta documento works, see our guide to demand letters in Argentina.
Sending one often works. A formal, documented demand frequently prompts payment or a negotiated arrangement without anything further being needed. But there’s an important limit worth understanding upfront: a carta documento does not, by itself, stop the statute-of-limitations clock on your claim. It creates evidence of the debtor’s default, which matters later if the case goes to court, but only an actual court filing, or the debtor’s own written acknowledgement of the debt, legally interrupts the limitation period. That distinction matters for anything you’ve waited a while to chase.
If the demand letter doesn’t resolve it, the path forward depends on how the debt is documented.
If the debt is backed by an enforceable instrument, a cheque, a promissory note (pagaré), or certain other formally recognised documents, it can generally be pursued through a juicio ejecutivo (executive proceeding), a streamlined court process designed specifically to collect on these instruments faster than an ordinary lawsuit. It’s common to request interim measures alongside it, such as freezing bank accounts or registering a general block on the debtor’s assets, to secure the possibility of actually collecting once you win.
Where there’s no cheque, pagaré, or equivalent, an ordinary civil claim is generally required instead of the executive process, a full lawsuit rather than the streamlined route. It takes longer and is more involved, which is exactly why the executive route is preferred whenever an enforceable instrument exists.
Realistic expectations matter here: even a straightforward executive proceeding typically takes several months to over a year to reach a final, enforceable judgment, and an ordinary claim usually takes longer. Collection is rarely instant, which is part of why a well-drafted demand letter, and understanding your legal deadlines, matter so much before it gets to this stage.
This is the part people most often get wrong, and it’s worth understanding clearly. Under the Código Civil y Comercial de la Nación, most civil and commercial claims have a general limitation period of five years from when the debt became due (Article 2560). But several common types of debt have a shorter specific period that overrides the general rule:
Because the applicable period depends on exactly what kind of debt it is, and how it’s documented, we confirm the specific deadline for your situation rather than assume the general five-year rule applies. If a debt has been outstanding for a while, this is the first thing to check, waiting too long can mean losing the legal right to collect through the courts entirely.
The other point worth repeating: sending a carta documento does not interrupt this clock. What does interrupt it is filing a court claim, or the debtor giving express written acknowledgement of the debt. If a debt is approaching its limitation period, that timing needs to shape your strategy, not just the size of the amount owed.
Argentine law generally allows a creditor to claim interest on a debt from the point it became overdue. Where a contract or agreement sets an interest rate, that rate typically applies. Where none was agreed, courts apply a reference rate that varies over time and by jurisdiction, so the exact figure needs confirming for your specific case rather than assumed from a fixed percentage.
The longer a debt sits, the closer it gets to its limitation period, and the harder it typically becomes to collect in practice, regardless of the legal deadline. Acting sooner, even just sending the formal demand letter, preserves your options.
As covered above, it doesn’t stop the clock. If a debt is old enough that the limitation period is a real concern, a demand letter isn’t enough on its own, the underlying deadline still needs to be managed.
If the debt is backed by a cheque, pagaré, or similar instrument, pursuing it through an ordinary claim instead of the faster executive process usually means a longer, more expensive route to the same result.
