e-Discovery and AI-assisted document review.
We preserve, organise and review documents for disputes and investigations. AI-assisted review combines human quality checks, criteria agreed with counsel and deliverables that make sources and methods easy to verify.
Context
Large document volumes. An organised body of evidence.
Document production orders, arbitrations, internal investigations and shareholder disputes can require thousands of files to be reviewed quickly. Emails, contracts and messages need clear review criteria and preserved source records.
LexNexo adapts the e-Discovery workflow to the matter: assessing the collection, processing documents and applying AI-assisted review with human checks. Counsel retains legal and privilege decisions; deliverables include sources, metrics and limitations.
Process
Six stages, each with a verifiable deliverable.
The workflow covers preservation, collection, processing, review and production. Each stage produces a verifiable record; counsel determines how it is used in the matter.
- 01
Preservation
Identification of custodians and sources; preservation instructions; freezing of repositories, mailboxes and messaging apps.
Deliverable: preservation plan and custody record
- 02
Collection
Forensic collection of email, cloud, devices and messaging apps, with hashes and documented chain of custody.
Deliverable: collection report with hashes
- 03
Processing
Deduplication, text and metadata extraction, Portuguese OCR and early case assessment: volume, custodians, terms and estimated cost before review.
Deliverable: volume-reduction and early-assessment report
- 04
AI review
Classification by relevance and personal data with multi-model AI; potentially privileged items flagged for counsel's decision; statistical sampling; human quality checks by specialists.
Deliverable: recall, precision and elusion metrics
- 05
Production
Final set in the format required by the court, tribunal or regulator, with production log and confidentiality handling.
Deliverable: production and index
- 06
Chronologies and support
Chronologies, fact maps and deposition dossiers built from the reviewed set, plus the methodology memorandum and technical clarifications.
Deliverable: chronology and methodology memorandum
Our approach
What changes when e-Discovery is designed for Brazil.
- 01
AI that reads legal Portuguese
Models evaluated on pleadings, contracts, corporate email and messaging conversations in Brazilian Portuguese, not merely translated. Review protocols are written with case counsel and converted into auditable instructions.
- 02
Documented defensibility
Every review round produces recall, precision and elusion metrics by statistical sampling, recorded in a memorandum. That is what sustains the methodology under challenge, expert examination or regulatory scrutiny.
- 03
Human control by specialists
AI prioritises and classifies; what is relevant or sensitive goes through human quality review by professionals with experience in the sector, and privilege calls stay with the client's counsel.
- 04
Data handling and costs agreed in scope
Data is stored and processed in Brazil. Volume, project or subscription pricing is set out in the proposal, including any additional charges.
Frequently asked questions
- How does e-Discovery support matters in Brazil?
- It is the technical work of preserving, processing, reviewing and organising digital documents for production requests, arbitration, investigations and disputes. Scope and selection criteria are agreed with counsel.
- Is AI review accepted by courts and regulators?
- Acceptance depends on the matter and the relevant authority. We document criteria, sampling, metrics and human review so the method can be scrutinised and explained.
- Where is the data kept?
- Data is stored and processed in Brazil. Providers, access controls and applicable project terms are documented before data processing begins.
- Does my case data train AI models?
- Training, retention and data-use rules are checked for each provider and configuration. These terms are documented before AI is used with case data.
- How is it charged?
- Per volume (gigabyte processed or document reviewed), per project with fixed scope, or by monthly subscription. The models are published; the amount is agreed in writing before the start.
- Is there a minimum volume?
- No. Small matters usually fit the per-project model; from tens of thousands of documents, per-volume pricing tends to be more advantageous.
