Cross border legal work often depends on moving sensitive contracts, court filings and evidence between languages without losing meaning, context or confidentiality. German language AI company DeepL is now strengthening its position in this market through a partnership with US legal AI company Harvey, bringing specialised document translation into Harvey’s legal workflow.
AI translation moves into high stakes legal work
DeepL said the partnership reflects growing demand for specialised AI tools capable of handling complex legal work, particularly as law firms and corporate legal teams increasingly operate across multiple jurisdictions. The agreement also marks another step in DeepL’s strategy of expanding beyond general purpose translation into heavily regulated industries where accuracy, security and consistency are critical.
Translating the documents behind legal deals
Harvey users work with a wide range of legal materials, including contracts, briefs, filings, evidence, reports and client documents. Many of these materials need to be translated quickly as lawyers work across jurisdictions.
Under the partnership, DeepL will provide translation capabilities for Harvey’s legal AI platform. DeepL is one of several translation partners working with Harvey and is expected to handle more than a third of the platform’s overall document translation volume.
The arrangement gives Harvey’s customers access to DeepL’s specialised language technology within a legal workflow rather than requiring lawyers to move documents between separate tools.
DeepL already offers document translation designed for legal professionals, including support for contracts, briefs and court filings while retaining document formatting. Its legal offering also includes terminology glossaries designed to keep specialised legal language consistent across documents.
Security becomes a key differentiator
Legal documents frequently contain confidential client information, commercially sensitive agreements and regulatory material. That makes data security a major consideration when introducing AI into legal workflows.
DeepL positions its enterprise language technology around data protection and security requirements. The company says its legal translation services use end to end encryption and comply with GDPR requirements, while translated content is deleted after processing under its stated legal service policies.
DeepL also operates its AI technology on proprietary infrastructure and says its enterprise products are designed around European privacy and security requirements.
For law firms, this combination of translation accuracy, confidentiality and workflow integration is increasingly important as AI becomes part of everyday legal operations.
DeepL targets regulated industries
The Harvey partnership comes as DeepL focuses more heavily on industries where language errors can have significant financial, legal or regulatory consequences.
The Cologne based company has been expanding its presence across sectors including legal services, financial services, pharmaceuticals and life sciences. Its strategy is built around the idea that specialised language AI can provide greater value in professional environments where generic translation tools may struggle with terminology and context.
DeepL’s legal technology can translate entire documents while preserving their original formatting and supports customised glossaries for consistent terminology. The company also offers translation through APIs, allowing organisations to integrate language capabilities into existing internal systems.
A wider push into professional AI
The partnership also highlights how AI companies are increasingly combining specialised capabilities rather than attempting to build every component themselves.
Harvey has built its platform around legal research, drafting, analysis and other workflows used by lawyers, while DeepL brings specialised language technology to the translation layer. Together, the companies can address an important part of international legal work without requiring lawyers to manage translation separately.
DeepL has also expanded beyond text translation into document and voice technologies. Its broader Language AI platform now supports text, files, voice and API based integrations across more than 100 languages.
For DeepL, the Harvey deal strengthens its position in legal AI while giving the company another route into enterprise workflows. For Harvey, the partnership adds specialised translation infrastructure as its platform expands across a global legal market where multilingual work is becoming increasingly important.
