Monitory action: how to collect when your written evidence is not an enforceable instrument?

Not every debt comes with a perfect enforceable instrument. Often, the company has some evidence that the amount is owed — a check that has become time-barred, a contract without witnesses, an exchange of e-mails, a spreadsheet of orders — but not a document that allows direct enforcement. In these cases, there is still a route that is faster than the ordinary action: the monitory action (ação monitória).

It is the middle ground between enforcement (which requires an instrument) and a collection action (slower). In this guide, you will understand what the monitory action is, when to use it, how it can save the collection of a time-barred check, how the procedure works and what the deadlines are.

What is the monitory action?

The monitory action (ação monitória) is the route to collect a debt when you have written evidence of it but no enforceable-instrument status (art. 700 CPC). It starts from a document that makes the claim plausible — although it is not, in itself, an enforceable instrument — and seeks, more swiftly than the ordinary proceeding, to create a court-issued enforceable instrument.

The statutory definition is clear: the monitory action may be brought by anyone who claims, on the basis of written evidence without enforceable-instrument effect, to have the right to require from the debtor the payment of a sum of money, the delivery of a thing or the performance of an obligation. In other words, it exists precisely to make use of written evidence that falls short of being an enforceable instrument — giving it a fast route to forced collection. It is a valuable tool for business credit.

When to use the monitory action instead of enforcement?

The choice between monitory action and enforcement depends, once again, on the document:

• Do I have an enforceable instrument (a valid check, promissory note, duplicata (trade bill), contract with two witnesses)? → Enforcement (faster, goes straight to attachment).

• Do I have written evidence but no enforceability (a time-barred check, a contract without witnesses, an informal acknowledgment of debt, e-mails, spreadsheets)? → Monitory action.

The monitory action is therefore the answer for when the instrument is missing but there is evidence to spare. It is worth noting: even someone who has an enforceable instrument may opt for the monitory action or for the ordinary cognition proceeding (art. 785 CPC), although enforcement tends to be the faster route when the instrument exists. Defining the best path is part of the legal diagnosis.

Can a time-barred check still be collected?

Yes — and this is one of the most valuable uses of the monitory action. A check has a short period for enforcement; once it has passed, the enforceability is lost. But that does not mean the debt is lost: the check remains written evidence of the claim and can support a monitory action.

The STJ has consolidated this understanding: Precedent 531 dispenses, in a monitory action based on a time-barred check, even with mentioning the transaction that gave rise to the instrument; and Precedent 504 sets at five years the period for the monitory action against the issuer of a promissory note without enforceability (reasoning also applied to the check). In other words, an instrument that is time-barred for enforcement is not necessarily a lost debt — only the route (from enforcement to the monitory action) and the period change. For this reason, it is worth reviewing old instruments before discarding them.

How does the monitory action procedure work?

The monitory action procedure has its own logic:

• 1. Filing: with the written evidence and the calculation of the debt, the action is brought.

• 2. Writ: satisfied that the claim is plausible, the judge orders the debtor to pay (or deliver the thing) within 15 days.

• 3. Debtor's response: the debtor may pay (ending the case, with reduced fees), remain inert or file objections (embargos).

• 4. Conversion into an instrument: if the debtor neither objects nor pays, the writ converts into a court-issued enforceable instrument, and the matter proceeds to enforcement.

• 5. Objections (embargos): if objections are filed, the discussion opens, as in an ordinary proceeding, before any instrument is formed.

The great advantage is procedural economy: if the debtor does not react, the instrument is reached quickly, without the lengthy evidentiary stage of an ordinary collection action.

A practical example: Têxtil Aurora's contract without witnesses

Têxtil Aurora, of São Paulo, supplied goods to a client on the basis of a contract and several e-mail exchanges confirming the orders and the amounts — but the contract did not have two witnesses, and was therefore not an enforceable instrument. The client stopped paying R$ 65 mil.

Without an instrument, Têxtil Aurora could not enforce directly. But it had robust written evidence (the contract and the e-mails). The proper route was the monitory action: the judge, satisfied that the claim was plausible, ordered the debtor to pay within 15 days. The client did not file objections — and the writ converted into a court-issued enforceable instrument, allowing attachment. The company recovered the debt much faster than in an ordinary collection action. The twofold lesson: the monitory action saved a collection without an instrument — and, had the contract had two witnesses, the company would have gone straight to enforcement, faster still.

The most common (and costly) mistakes

• Discarding time-barred instruments. A time-barred check can still be collected through a monitory action — do not throw away the evidence.

• Confusing the routes. If you have an instrument, enforcement is faster; without one, the monitory action is the right route.

• Missing the monitory action's deadline. Even the monitory action becomes time-barred (five years, as a rule) — do not let it age.

• Gathering weak written evidence. The clearer the evidence (contract, e-mails, spreadsheets), the more solid the monitory action.

• Underestimating the objections (embargos). If the debtor files objections, the discussion must be conducted skillfully.

Checklist: before filing the monitory action

• Confirm that you have written evidence of the debt (even without enforceability).

• Check whether the route is indeed the monitory action (and not enforcement, if there is an instrument).

• Calculate the limitation period applicable to the document.

• Organize the evidence (contract, e-mails, time-barred instrument, spreadsheets) and the calculation.

• Prepare for the possible objections (embargos) stage.

• Conduct the action with a Business Law attorney.

Frequently asked questions about the monitory action

What is a monitory action?

It is the action to collect a debt when you have written evidence but no enforceable-instrument status (art. 700 CPC). It works, for example, for an already time-barred check or promissory note, a contract without two witnesses, or e-mails or spreadsheets that prove the debt. The goal is, more quickly than an ordinary action, to create a court-issued enforceable instrument and move to collection. It is a middle ground between enforcement and a collection action.

When do I use a monitory action instead of enforcement?

You use the monitory action when an enforceable instrument is lacking. If you have a check, promissory note, duplicata (trade bill) or a contract with two witnesses, the route is enforcement (faster). If the document has lost its enforceability — a time-barred check, for example — or never had it (a contract without witnesses, an informal acknowledgment of debt, e-mails), the proper route is the monitory action, which turns that written evidence into a court instrument.

Can a time-barred check still be collected?

Yes, through the monitory action. Even after the deadline for enforcement has run out, the check remains written evidence of the debt and can support the monitory action (STJ Precedent 531 even dispenses with mentioning the transaction that gave rise to the check). The limitation period for the monitory action on a check is five years (STJ Precedent 504 applies similar reasoning to the promissory note). For this reason, an instrument that is time-barred for enforcement is not necessarily a lost debt.

How does the monitory action procedure work?

With the written evidence, the monitory action is filed. If the judge is satisfied that the claim is plausible, the court orders a writ for the debtor to pay (or deliver the thing) within 15 days. The debtor may pay, remain inert, or file objections (embargos). If the debtor neither objects nor pays, the writ converts into a court-issued enforceable instrument and the matter proceeds to enforcement. The objections (embargos) stay the order and open the discussion, as in an ordinary proceeding.

How long do I have to file a monitory action in São Paulo?

The deadline depends on the nature of the claim, but it is important not to let it become time-barred. For collection based on a time-barred check, the STJ has set a five-year period; for a promissory note without enforceability, STJ Precedent 504 also sets five years, counted from the due date. In São Paulo, the action proceeds in the competent court. A lawyer checks the limitation period applicable to your document before the chance to collect is lost.

Do I need a lawyer for the monitory action?

Yes, because it is a court action. And technical work matters: you must assess whether the document serves as written evidence, calculate the limitation period, properly draft the complaint, and conduct the objections (embargos) stage, if any. A Business Law attorney in São Paulo advises whether the monitory action is the right route (rather than enforcement or a collection action) and conducts the case through to the creation of the instrument and payment.

Written evidence becomes money too

The monitory action exists so that written evidence that does not amount to an enforceable instrument — a time-barred check, a contract without witnesses, e-mails — is not lost. It turns this evidence into an enforceable instrument quickly, above all when the debtor does not react, and opens the way to forced collection.

The secret is to recognize the right route and act within the deadline: many claims given up as lost (because the instrument became time-barred) can still be recovered through the monitory action. Reviewing old documentation, with guidance, often reveals opportunities.
