If a Brazilian client has not paid for freelance work and there is no signed contract, start by assembling the facts rather than assuming there is no agreement or that WhatsApp alone proves the claim. Identify who hired you, what you accepted, what you delivered, what the customer accepted or disputed, when payment became due, and which messages support each point. Then check whether negotiation, a formal demand, a Juizado Especial Cível (JEC), or an ordinary civil action fits the value, parties, evidence and local court rules.

This sequence answers two connected questions: can a freelancer pursue a debt without a formal signature, and how should the freelancer preserve WhatsApp evidence? The answer depends on the agreement and proof, not on one screenshot. Brazil’s Code of Civil Procedure recognizes broad evidentiary means in art. 369 and describes notarial records in art. 384. Those provisions do not mean that a message automatically proves every disputed fact or that an ata notarial is always required.

First identify the person or business that owes the fee

A conversation may involve a project manager, franchisee, agency, end client and payment intermediary. The person who sent messages is not necessarily the contracting debtor. Put the relationship on one page:

  • Who requested the service and approved the fee?
  • Was the agreement with an individual, company, MEI, franchisee, agency or end customer?
  • Who provided the brief and controlled acceptance?
  • Who received the work and used it?
  • Who promised payment, and in what capacity?
  • Did another party promise to pay if the end client did not?

Do not assume that an agency’s failure to collect from its customer excuses the agency’s own payment obligation. Equally, do not name a different person in a claim just because they have assets or appeared in a chat. The contract, messages, invoice recipient, payment history and commercial arrangement help identify the proper defendant; have a Brazilian lawyer check the proposed claim if the parties are unclear.

Reconstruct the deal and delivery timeline

Create a chronology with dates, people, documents and what each item proves. A simple spreadsheet is enough; label disputed points as disputed rather than writing them as established facts.

QuestionUseful recordsWhat the record may help show
What was the scope?Proposal, voice notes, messages, email, task briefWork requested, exclusions, price and deadlines
Was the fee agreed?Quote acceptance, invoice, rate messages, purchase orderAmount, payment trigger and agreed payer
Was the work done?Source files, delivery link, work log, drafts, ticket historyPerformance, timing and version delivered
Was delivery accepted or challenged?Approval message, meeting notes, change request, defect listAcceptance, requested corrections or dispute
When did payment fall due?Invoice, milestone schedule, payment terms, later messagesMaturity date and any agreed extension
Was the debt acknowledged or partly paid?Payment receipt, written promise, reconciliationPayment history and the debtor’s stated position

Keep the original files and export source data where practical. Do not edit timestamps, delete adverse messages, crop out context, access someone else’s account, or post private communications online to pressure the other side. Preserve a copy of the complete conversation and relevant media on a secure device. A screenshot can be useful as a readable exhibit, but it is better supported by context and provenance than presented alone.

Preserve WhatsApp without overstating what it proves

For the relevant conversation, preserve the phone and account that received or sent it, the full conversation around the key message, contact identification, timestamps, voice notes and attachments. Save the export in its original form and keep an untouched backup. Make a separate working copy for highlighting or redaction. Record when and by whom each export was made, and avoid changing the source file.

If authenticity is likely to be contested, consider asking counsel whether a notarial record under CPC art. 384, technical preservation or another corroborating record is proportionate. A notarial act records what the notary observes; it does not itself prove the truth of every statement, the identity of an account holder, the authority of a sender, or the legal meaning of a contract. Other corroboration may include the delivered project, invoice, access logs, a reply acknowledging the amount, or a partial payment.

For material in audio or image form, preserve the original and keep a transcript or description separately. Identify who created it and when, and be ready to explain the context. If the messages contain customer data, credentials or trade secrets, handle them securely and share only what is relevant through the proper channel.

Choose a recovery route after checking JEC eligibility

The Juizados Especiais Cíveis law, Lei 9.099/1995, sets the JEC’s civil jurisdiction for specified lower-complexity cases and value limits. Article 3 includes causes up to 40 minimum wages and listed categories, but exclusions and other conditions matter. Article 8 limits who may sue; it includes natural persons and certain microentrepreneurs, microenterprises and small businesses under the statutory framework. Under art. 9, a lawyer is optional for claims up to 20 minimum wages and required above that in JEC proceedings. The exact claimant, legal entity, claim type, amount and current law should be checked before selecting the forum.

JEC access does not guarantee a fast decision, payment, electronic filing in every location, or successful enforcement. If the facts require technical evidence, multiple parties, complex accounting or relief outside the JEC’s scope, another civil procedure may be more appropriate. A company claimant should not assume that any corporate form can file in a JEC. Check the local court’s official website for current filing instructions and whether the named claimant qualifies.

Before filing, compare these practical steps:

  1. Send a clear, factual payment request to the likely debtor, itemizing the service, invoice, due date, amount and a reasonable response date. Avoid threats or public accusations.
  2. Keep proof of sending and delivery, plus any reply or counterproposal.
  3. Decide whether you will accept a payment plan and record the amount, dates, default consequence and confirmation in writing.
  4. Confirm venue, claimant eligibility, value, limitation period, filing method and required copies with the local court or Brazilian counsel.
  5. Prepare an indexed evidence packet with a short chronology and one exhibit per point; do not dump an unorganized chat history on the court.

Hypothetical: a small job promised by chat

Suppose Bruno is asked by a marketing agency to prepare a short campaign analysis for a franchise location. A WhatsApp exchange states a fixed R$750 fee and a delivery date. Bruno sends the report link; the agency replies “received, looks good” and later promises payment after its own client pays. Three months pass. There is no signed service agreement.

Bruno can identify the agency entity and invoice recipient, preserve the entire message thread and report file, and build a chronology linking the request, fee, delivery, acceptance, due date and later payment promise. He can ask the agency to confirm the balance and payment date in a concise written demand. Before selecting a court, he should check whether he is suing as an individual or business, whether the amount and issue fall within local JEC jurisdiction, and whether the agency is the proper debtor. The available facts support investigation; they do not guarantee that a court will find liability or that collection will succeed.

Common mistakes

  • Assuming no signed paper means no contract existed, or assuming a chat automatically proves all elements.
  • Suing a franchise brand, end customer or individual without verifying who contracted.
  • Preserving only a cropped screenshot while losing the original conversation or media.
  • Editing, annotating or exporting a working copy without retaining an untouched source copy.
  • Treating a payment promise as an unconditional admission without reading the full exchange.
  • Filing in JEC without checking whether the claimant’s legal form and claim are eligible.
  • Relying on online comments that promise a short timeline, damages, easy collection or free counsel.
  • Demanding moral damages, interest or fees without checking the facts and legal basis.
  • Publicly shaming the debtor or disclosing personal information, which can create new issues.

Frequently asked questions

Can I recover freelance fees in Brazil without a signed contract?

Possibly, but the absence of a formal signature does not answer whether the parties agreed or whether the claim can be proved. A lawyer will consider messages, proposal, delivery, acceptance, invoices, payment history and applicable formalities. Do not treat a verbal or chat-based arrangement as automatically enforceable or automatically invalid.

Are WhatsApp messages accepted as evidence in Brazil?

The CPC permits legally relevant evidence, and electronic records can be considered under the applicable rules. The court may examine authenticity, context, completeness and reliability. Preserve the source and corroborating records; no platform makes a message conclusive by itself.

Do I need an ata notarial for every WhatsApp claim?

No. CPC art. 384 provides for a notarial record of facts the notary can attest to, but it does not make that step mandatory in every case. Ask counsel whether it is proportionate when authenticity is disputed or the amount and stakes justify the cost.

Can an individual file a small unpaid invoice in the JEC?

Some civil claims may fit, but check subject matter, amount, complexity, venue and claimant eligibility under Lei 9.099/1995. The statute has limits on parties and says when legal representation is mandatory. Local court instructions also matter.

Can my MEI or company use the JEC?

Some microentrepreneurs and small businesses may qualify under art. 8 and related statutory definitions, but not every business entity is eligible. Verify the claimant’s legal form and current qualification before filing.

A clear written demand can help document the request, clarify the amount and invite resolution. Whether formal notice is legally required depends on the claim and contract. It does not automatically extend limitation periods or guarantee a better result.

What if the person who promised payment is not the company owner?

Preserve the messages and identify the person’s role and authority. The promise may be evidence, but do not assume the individual is personally liable or that the company is bound without reviewing the relationship and applicable law.

Can I add damages because the client delayed payment?

Do not add a damages category solely because payment was late. Interest, correction, penalty, moral damages and costs each require a legal and factual basis. Ask Brazilian counsel to calculate and plead the claim correctly.

How long will a JEC claim take, and will I get paid?

There is no guaranteed duration or collection outcome. Hearings, service, evidence, settlement, appeal and the defendant’s ability to pay can affect the result. Verify current local processing information and consider practical collectability before choosing a route.

For help organizing the underlying records, explore Gotham’s legal workflows or contact the team. Document organization is not a legal determination or a promise of recovery.

General information, not legal advice. Brazilian claim procedures, evidence assessment, limitation and eligibility depend on the facts and current local rules.
