Why Law Firms Choose M21Global

Law firms choose M21Global because we understand the standards legal work demands. Every legal translation is assigned to a linguist with proven experience in the relevant area of law, whether corporate, litigation, regulatory or intellectual property. Our in-house lawyers review certifications and handle authentication, ensuring that translated documents meet the formal requirements of the receiving jurisdiction.

Confidentiality is non-negotiable. We sign project-specific NDAs before receiving any documents, use encrypted file transfer, and restrict access to authorised team members. Our processes comply with GDPR and Portuguese data protection legislation. For law firms, we offer dedicated account management with a single point of contact who understands your practice area and terminology preferences.

Document Types We Handle

M21Legal translates the full range of documents that law firms work with: commercial contracts and international agreements, court filings and judgments, powers of attorney and notarial acts, corporate governance documents (articles of association, board resolutions, shareholder agreements), due diligence materials, compliance and regulatory submissions, and intellectual property documentation.

We also handle large-volume discovery and disclosure projects, translating document sets for international arbitration or cross-border litigation. For recurring matters, we build case-specific glossaries and translation memories that ensure terminological consistency across all documents, even when projects span months or involve multiple language pairs.

Working with International Legal Teams

M21Global's Lisbon location in the CET/WEST timezone offers convenient overlap with business hours across Europe, the Middle East, Africa and the Americas. Our project managers are experienced in working with international legal teams, coordinating across offices and time zones to meet litigation deadlines and transaction timetables.

We deliver translations in your preferred format, including tracked-changes versions for review by your legal team. For urgent matters, we offer express service with dedicated linguist teams. Secure delivery is standard, with encrypted channels and restricted access. Whether your firm is in London, New York, Frankfurt or Sao Paulo, you receive the same level of service, responsiveness and quality.
