WhatsApp expert report: turn your conversations into court evidence

Forensic analysis of chats, audio and multimedia with chain of custody and an expert witness available to testify in court.

A WhatsApp screenshot can be challenged in five seconds flat — any lawyer will argue it's been manipulated. The expert report extracts the conversation directly from the device or backup, calculates the evidence hash, verifies it hasn't been edited, and documents every step in a chain of custody that the expert witness can confirm before the judge.

Forensic extraction from the device, not screenshots
SHA-256 hash certifying integrity
Analysis of metadata and deleted messages
Documented chain of custody
Forensic IT expert available to testify in court

3
Technical analysis
⏱ 24-48 h
Integrity verification, metadata review, timeline reconstruction, recovery of deletable messages and detection of manipulation.
4
Report and courtroom confirmation
⏱ 48-72 h
Signed report including methodology, conclusions and appendices. The expert witness appears in court if the proceedings require it.

Frequently asked questions

How long does the forensic report take?
The complete process takes between 5 and 7 business days from the forensic extraction. In urgent cases, we can expedite the process.
How is the conversation extraction performed?+
We use professional forensic tools that guarantee data integrity. We can perform the extraction in person or send you secure instructions if you are in another city.
Is the report valid in court?+
Yes, our reports have full court validity. They are prepared by certified digital forensic experts who can ratify the report before the court.
Can I take screenshots myself?+
It is not recommended. Simple screenshots can be challenged in court. It is essential to perform a professional forensic extraction that preserves metadata and guarantees the chain of custody.
Which devices are compatible?+
We work with iPhone (iOS) and Android. The process varies depending on the operating system, but in both cases, we guarantee forensic validity.
Do I need to physically bring my phone?+
It depends on the case. For in-person extractions, yes, it is necessary. In some cases, we can work with securely sent backups. We advise you on the best option for your situation.
Can deleted messages be recovered?+
In some cases, it is possible to recover deleted messages, depending on the time elapsed and the device. Consult your specific case with us.
How much does the forensic report cost?+
The price depends on the complexity of the case and the volume of conversations. Contact us for a personalized no-obligation quote.
What information does the forensic report contain?+
The report includes: complete extraction of the msgstore.db database, full textual transcription of conversations, metadata analysis (dates, times, delivery/read status), participant identification, multimedia file extraction (photos, videos, audio, documents), SHA-256 cryptographic hashes, manipulation analysis if any, complete chain of custody, technical conclusions, and forensic annexes. All documented according to ISO/IEC 27037 standards.
Can the expert testify in court?+
Yes, our forensic experts are prepared to appear in court, ratify the forensic report, answer questions from the parties and the court, and technically explain the methodology applied. Their experience and professional certifications guarantee credibility before any judge.
Can WhatsApp Business be analyzed?+
Yes, the forensic process is applicable to both personal WhatsApp and WhatsApp Business. The database structure is similar, although WhatsApp Business contains additional business profile information, catalogs, and labels that are also included in the analysis if relevant to the case.
What happens if the other party denies the authenticity of the conversations?+
That is precisely why the forensic report exists. The forensic analysis includes metadata verification, cryptographic hashes, analysis of the underlying database, unique device and user identifiers, and other technical elements that scientifically demonstrate authenticity, beyond simple easily questionable screenshots.
How many conversations can I include in the report?+
There is no technical limit. We can analyze from a single individual chat to multiple conversations, complete groups, or total WhatsApp extractions. In cases with many conversations, we can focus the analysis on chats relevant to the legal process. The price adjusts according to the volume of data.
Can it be done without physically having the phone?+
In some cases, it is possible to work with cloud backups (iCloud for iPhone, Google Drive for Android) or with local exports. However, for maximum forensic guarantee and recovery of deleted messages, direct device access is preferable. We advise you on the best option according to your specific case.
What is the difference between exporting conversations and a forensic report?+
Native WhatsApp export (.txt or .zip format) does not include all forensic metadata, may omit deleted messages, does not preserve the digital chain of custody, and is easily challengeable in court. A forensic report extracts directly from the encrypted database, preserves ALL forensic data, includes hashes that guarantee integrity, documents the scientific methodology, and has full procedural validity before any court.
Why isn't a WhatsApp screenshot valid in court?+
Because it can be trivially manipulated: there are apps that generate fake conversations indistinguishable from real ones. Case law (STS 300/2015) requires expert evidence when the opposing party challenges the content, and in practice they always do. The report provides the evidence hash and traceability that a screenshot simply cannot offer.
Can messages the other person deleted be recovered?+
Sometimes: if the deletion only happened on their device, your copy remains intact and can be analyzed. If it was deleted on yours, we attempt recovery from the local database and backups. The report always distinguishes what was recovered from what couldn't be, without promising the impossible.
Is it legal to have a chat I'm part of examined?+
Yes. You're a participant in the conversation and can submit it as evidence. What is not lawful is accessing someone else's phone without authorization or a court order — that evidence would be declared void and could even constitute a crime.
Does the expert witness attend the trial?+
Yes, appearing in court to confirm the report is included in our service. A report that no one can defend before the judge loses half its value.
What if I already forwarded the messages by email?+
Forwarding alters the metadata and weakens the report, but doesn't rule it out — we'll work with the original device if it's still available. That's why the first thing we ask is that you don't touch anything else.
How long does it take and how much does it cost?+
Standard delivery is 48 to 72 hours. The price depends on the volume of conversation, the number of devices involved, and whether courtroom testimony is required; we provide a fixed quote after the initial consultation.
Do documents signed online have the same validity as those signed in person?+
Exactly the same. Law 11/2023 recognises the full legal validity of notarial documents executed by video call with a qualified electronic signature before a registered notary.
Do I need a digital certificate?+
Yes, to sign electronically you need a digital certificate or an electronic DNI. If you do not have one, we help you obtain it quickly before your appointment, with no additional handling fee.
Can I do it from abroad?+
Yes, the notarial video call works from any country. You only need a stable connection, your valid identity document and a digital certificate.
How much does this service cost?+
The quote includes the official notarial fees set by the Notarial Association plus our handling, fixed before you start and with no hidden costs. Request it with no obligation via WhatsApp or the form.
What if I have questions during the process?+
Our team supports you from start to finish via WhatsApp, phone or email, and the notary answers all your legal questions before signing.
