Protested bills of exchange and promissory notes in Peru: what 'protesto' means and what happens if you don't pay

The core misconception: thinking they have to win a lawsuit before they can collect

When someone signs a bill of exchange (letra de cambio) or a promissory note (pagaré) and then can’t pay, it’s common to assume the creditor has to sue, wait through a long trial, and only after a final judgment could they try to collect. That’s not how it works for these documents. Peru’s Ley de Títulos Valores (Law No. 27287) gives a bill of exchange or a promissory note, once it meets its formal requirements, something called mérito ejecutivo (executive merit):

“18.1 Los títulos valores tienen mérito ejecutivo, si reúnen los requisitos formales exigidos por la presente Ley, según su clase. 18.2 El tenedor podrá ejercitar las acciones derivadas del título valor en proceso distinto al ejecutivo, observando la ley procesal.” (Title documents have executive merit if they meet the formal requirements this Law demands, according to their class. The holder may pursue the actions arising from the título valor in a process other than the executive one, following procedural law.)

In plain terms: the signed document is, by itself, sufficient proof of the debt. That lets the creditor go straight to an executive process — a shorter court route focused on collection, without needing a prior lawsuit to establish that the debt exists. But before getting there, there’s almost always an intermediate step: the protesto.

What a protesto is, and why it’s the key to the executive process

A protesto is the formal record that the título valor wasn’t paid — or, for a bill of exchange, wasn’t accepted — within the deadline. Article 70 describes it as a mandatory, not optional, formality to exercise the actions arising from the document:

“70.1 […] en caso de incumplimiento de las obligaciones que representa el título valor, debe dejarse constancia de ello mediante el protesto o, en su caso, debe observarse la formalidad sustitutoria que se establece, la que surtirá los mismos efectos del protesto. 70.2 En los títulos valores sujetos a protesto, el protesto o formalidad sustitutoria […] constituye formalidad necesaria para el ejercicio de las acciones cambiarias respectivas.” (If the obligations represented by a título valor are defaulted on, this must be recorded through the protesto or, where applicable, the substitute formality established, which has the same effects as the protesto. For títulos subject to protesto, obtaining the protesto or substitute formality is a necessary formality to exercise the corresponding cambiario actions.)

The protesto is carried out by a notary (or, if there’s no notary in the area, by a justice of the peace) through a notice addressed to the obligor. If the obligor doesn’t show up to comply that same day or the next business day, the certifying officer records the default directly on the document, with the phrase “Documento Protestado” (Protested Document). That marked document, on its own, is enough to start cambiario actions, with no further paperwork needed.

This ties directly into the requirement for suing: Article 91 requires, for títulos subject to protesto, that it have been carried out before the cambiario action can be exercised.

”[…] para ejercitar las acciones cambiarias […] constituye requisito obligatorio: a) En los títulos valores sujetos a protesto, haberse verificado el mismo.” (To exercise the cambiario actions, it is a mandatory requirement that: a) for títulos valores subject to protesto, it have been carried out.)

The deadlines to protest aren’t flexible

Article 72 sets strict deadlines depending on the type of default. The one most relevant to most cases — the protesto for non-payment — gives 15 calendar days after the document’s due date. These are not business days: article 75.2 clarifies that non-business days falling within the period do count, and only the final day of the period shifts to the next business day if it lands on a holiday, Saturday, or Sunday:

“Si se trata de protesto por falta de pago de la suma dineraria que representa, dentro de los 15 (quince) días posteriores a su vencimiento, con excepción del Cheque y de otros títulos valores con vencimiento a la vista.” (For a protesto due to non-payment of the amount represented, within 15 (fifteen) days after its due date, except for the Cheque and other títulos valores payable on demand.)

Within that period, the creditor must hand the document to the notary or certifying officer within the first 8 days. Different deadlines apply to protesting a bill of exchange for non-acceptance and to instruments payable on demand, and the Cheque has its own presentation rules, outside the scope of this page.

The ‘sin protesto’ clause: the exception almost everyone signs without reading

Many bills of exchange and promissory notes — especially the ones issued by financial institutions — include, right from the moment they’re issued, the ‘sin protesto’ clause (or an equivalent one). Article 81 explains its effect:

“81.1 Tratándose de títulos valores sujetos a protesto, es válida la cláusula ‘Sin Protesto’ u otra equivalente que se incluya en el texto del título valor […], que libere al tenedor de la obligación de protestar el documento. En estos casos, la acción cambiaria se ejercitará por el solo mérito de haber vencido el plazo señalado en el título valor.” (For títulos valores subject to protesto, the ‘Sin Protesto’ clause or an equivalent one, included in the title’s text, is valid and frees the holder from the obligation to protest the document; in that case the cambiario action is exercised on the sole merit of the deadline stated on the document having expired.)

In other words: if your promissory note or bill of exchange has this clause, the creditor doesn’t need to go through the notarial protesto procedure — it’s enough for the due date to arrive for them to be able to sue you through the executive process. There’s an important exception that often goes unnoticed, though: this clause doesn’t apply to protesting a bill of exchange for non-acceptance.

“La cláusula sin protesto a que se refiere el Artículo 81 no resulta aplicable al protesto por falta de aceptación de la Letra de Cambio. El protesto por falta de aceptación deberá llevarse a cabo aun en la Letra de Cambio que contenga dicha cláusula.” (The ‘sin protesto’ clause referred to in Article 81 does not apply to the protesto for non-acceptance of a bill of exchange. The protesto for non-acceptance must still be carried out, even in a bill of exchange that carries this clause.)

In other words: if you’re the drawee of a bill of exchange (the one being asked to accept it) and you refuse to accept, whoever holds it does have to protest it for that specific non-acceptance, even if the document says ‘sin protesto.’

A bill of exchange and a promissory note aren’t exactly the same thing

Both are títulos valores subject to protesto, and both, once they meet their requirements, have executive merit — but the structure is different. A bill of exchange is a payment order: whoever issues it (the drawer) orders a third party (the drawee) to pay a specific person. The drawee only becomes the principal obligor once they accept the bill. Article 119 requires, among other things, that this order be clearly stated:

“La Letra de Cambio debe contener: a) La denominación de Letra de Cambio; b) La indicación del lugar y fecha de giro; c) La orden incondicional de pagar una cantidad determinada de dinero o una cantidad determinable de éste […]; d) El nombre […] de la persona a cuyo cargo se gira; e) El nombre de la persona a quien […] debe hacerse el pago; f) El nombre […] y la firma de la persona que gira la Letra de Cambio; g) La indicación del vencimiento; y h) La indicación del lugar de pago.” (The bill of exchange must contain: a) the label ‘Letra de Cambio’; b) the place and date it was drawn; c) the unconditional order to pay a determined or determinable amount of money; d) the name of the person it is drawn against; e) the name of the person to be paid; f) the name and signature of the drawer; g) the due date; and h) the place of payment.)

A promissory note, by contrast, is a direct promise: whoever signs it (the maker) commits, themselves, to paying, and is the principal obligor from the moment they sign it, with no one else needing to accept it. Article 158 sets its own requirements:

“El Pagaré debe contener: a) La denominación de Pagaré; b) La indicación del lugar y fecha de su emisión; c) La promesa incondicional de pagar una cantidad determinada de dinero o una cantidad determinable de éste […]; d) El nombre de la persona a quien […] debe hacerse el pago; e) La indicación de su vencimiento […]; f) La indicación del lugar de pago; g) El nombre […] y la firma del emitente, quien tiene la calidad de obligado principal.” (The Pagaré must contain: a) the label ‘Pagaré’; b) the place and date it was issued; c) the unconditional promise to pay a determined or determinable amount of money; d) the name of the person to be paid; e) its due date; f) the place of payment; and g) the name and signature of the maker, who has the status of principal obligor.)

A protesto gets recorded, and that can affect your credit history

A protesto doesn’t stay just between the notary, the debtor, and the creditor. Article 85 requires certifying officers to report every protesto, monthly, to the corresponding provincial Chamber of Commerce, which in turn centralizes that information in the National Register of Protests and Defaults run by the Lima Chamber of Commerce:

“Los Fedatarios están obligados, bajo responsabilidad, a remitir a la Cámara de Comercio Provincial del lugar del protesto […] una relación de todos los protestos realizados por ellos durante ese lapso […]. Las Cámaras de Comercio […] están obligadas a mantener registradas, durante 5 (cinco) años […] las informaciones a que se refiere el presente artículo […]; salvo que el título valor protestado o incurrido en mora haya sido pagado totalmente, en cuyo caso el registro debe mantenerse durante 3 (tres) años […]. La Cámara de Comercio de Lima […] mantendrá y conducirá el Registro Nacional de Protestos y Moras.” (Certifying officers must, under their own responsibility, send the provincial Chamber of Commerce of the place of protesto a list of every protesto they carried out during that period. The Chambers of Commerce must keep this information on record for 5 years, unless the protested or defaulted document was paid in full, in which case the record is kept for 3 years. The Lima Chamber of Commerce maintains and runs the National Register of Protests and Defaults.)

This information is public and feeds credit bureaus like Infocorp, through the same mechanisms and update deadlines explained on the page about negative credit reports.

Foreigners and businesses

These rules apply regardless of nationality: what generally determines that Peru’s Ley de Títulos Valores governs a protesto is that the document is payable in Peru, not the nationality of the signer or of the person collecting on it. And while in everyday practice these documents are common in personal loans and consumer financing, the law regulates them the same way no matter who signs: an individual, a self-employed worker, or a business.
