In the digital world, where negotiations happen at dizzying speeds, digital oral contracts have become a common practice, but one fraught with risks.
These agreements, made via text messages, emails, or even conversations on messaging apps, are verbal or textual promises without clear legal formalization.
Therefore, although they may seem practical, they can lead to confusion, disputes, and even significant financial losses.
Why, after all, can something so simple turn into a trap?
This text explores what these contracts are, their dangers, practical examples, and how to avoid them to protect your interests.

What are Digital Word of Mouth Contracts?

First, imagine a scenario where you arrange a service via WhatsApp, receive confirmation, and begin work.
This is the core of a digital mouth contract: an informal agreement, usually recorded on digital platforms, but without the structure of a formal contract.

Unlike traditional contracts, which have clear clauses, signatures and legal validation, these agreements depend on the good faith of the parties.
However, the lack of formality makes them vulnerable to the law.
In practice, these contracts arise in everyday situations, such as hiring a freelancer for a project or selling a product on marketplaces.
The ease of digital communication encourages these quick negotiations, but lack of documentation can be a problem.
For example, a message saying “Closed, delivery in 10 days” may seem sufficient, but what happens if deadlines change or payment isn’t made?
In short, the lack of clear terms makes conflict resolution difficult.
Furthermore, the perception that “everything is recorded” in chats or emails is misleading.
Often, these exchanges are ambiguous, lack detail, or lack solid legal validity.
Thus, while technology facilitates agreements, it also increases the risk of misunderstandings, making it essential to understand the limits of these digital “contracts.”
| Features | Digital Mouth Contract | Formal Contract |
|---|---|---|
| Formality | Informal, message or email based | Structured, with clauses and signatures |
| Legal Validity | Fragile, dependent on judicial interpretation | Strong, legally recognized |
| Clarity | Ambiguous, subject to misunderstanding | Of course, with defined terms |
| Proof | Relies on screenshots or logs | Signed and authenticated document |
Why Digital Word of Mouth Contracts Can Be a Headache?

The main trap of digital oral contracts lies in its ambiguity.
A text message conversation may seem clear at the time, but in litigation, each party may interpret the agreement differently.

For example, if a client promises to pay “as soon as the project is delivered,” but doesn’t specify deadlines or payment methods, how can you prove what was agreed upon?
In this sense, this lack of clarity can lead to prolonged and costly disputes.
Furthermore, another problem is the difficulty of legal proof.
In Brazil, the Civil Code recognizes verbal contracts in some situations, but requires robust evidence, such as witnesses or clear records.
WhatsApp messages, for example, can be deleted, manipulated, or even contested as evidence.
According to a study by the Brazilian Electronic Commerce Association (ABComm), in 2024, around 12% of e-commerce disputes involved informal agreements, resulting in losses of up to R$1.2 billion.
In short, this data highlights how digital informality can be costly.
Think about us digital oral contracts like a rope bridge over a chasm: it can take you to the other side, but any misstep could result in a fall.
Excessive reliance on the written word in chats, without formal support, is like walking across that bridge without checking its strength.
Thus, the risk is not only in the agreement itself, but in the absence of a structure that protects both parties.
| Risks | Impact | Suggested Solution |
|---|---|---|
| Ambiguity | Misunderstandings about deadlines or amounts | Specify terms in a formal contract |
| Lack of evidence | Difficulty in legal disputes | Use platforms with tracking |
| Default | Financial losses | Require deposits or signed contracts |
Practical Examples of Problems with Digital Word of Mouth Contracts

Example 1: The Helpless Freelancer
Mariana, a graphic designer, was hired by a client via Instagram to create a logo.
The agreement, made via direct messages, stipulated R$ 500 for the service, with delivery within a week.
Mariana delivered the work, but the client claimed it was “not what was expected” and refused to pay, stating that there was never a “real contract.”
++ How to Create a Service Proposal That Avoids Rejection
Without a formal document, Mariana struggled to prove the agreement, and the case dragged on for months in small claims, causing stress and emotional toll.
In this sense, this case illustrates how the lack of formalization can leave professionals vulnerable.
Mariana trusted the messages, but there was no clarity about reviews, payment deadlines, or penalties.
In short, a formal contract would have avoided the problem by setting expectations and protecting your work.
Example 2: The Sale That Went Wrong
João, a small entrepreneur, sold a batch of products through a WhatsApp group, arranging delivery and payment via Pix with a buyer.
The agreement was “pay half upon delivery, half later”.
After delivery, the buyer paid only the first installment and disappeared.
João tried to take legal action, but the group's messages were vague, with no details about deadlines or penalties.
So he wasted time and money trying to recover the value.
This example highlights how informality in digital sales can lead to losses.
A contract, even a simple one, would have stipulated clear conditions, such as late fees or payment guarantees.
How to Avoid Problems with Digital Word of Mouth Contracts

| Digital contracts | Legal validity | Contraktor, DocuSign |
| Traceable payments | Proof of transaction | PagSeguro, Mercado Pago |
