Slaughter and May deploys Harvey AI across all practice areas firmwide
Slaughter and May has announced the firmwide rollout of Harvey’s artificial intelligence platform across all of its practice areas. The international law firm said the platform will support lawyers working on multi-jurisdictional matters, including mergers and acquisitions, due diligence, regulatory research, and document analysis.
The move marks a significant expansion of the firm’s use of artificial intelligence tools as large commercial law firms continue increasing investment in legal technology and AI-assisted workflows. According to Slaughter and May, Harvey was selected following an assessment of its security standards, agentic AI capabilities, and experience supporting AI implementation within major law firms. The firm also cited Harvey’s presence across its client base and its ability to meet the firm’s operational and professional standards.
David Johnson said the adoption of Harvey would support the firm’s client service while maintaining human oversight of AI-generated work. He stated that investment in the firm’s people remained central to the rollout, describing lawyers as the “vital human layer” responsible for supervising AI use.
Sally Wokes said the technology would allow the firm to connect and apply its expertise more effectively across different legal matters. She added that AI could enhance the collective judgment, creativity and problem-solving capabilities lawyers bring to client work.
As part of the implementation process, Harvey’s Transformation Office will work directly with Slaughter and May to support deployment of the technology and assist with responsible adoption across the business. Harvey said its Transformation Office includes legal professionals and specialists focused on law firm AI integration.
Winston Weinberg described the agreement as part of a broader trend towards AI adoption within leading law firms. He said Slaughter and May had combined longstanding legal expertise with openness to new technologies throughout its history.
The announcement reflects growing competition among international law firms to integrate generative AI tools into legal workflows while maintaining professional oversight and compliance standards. Law firms across the UK and internationally have increasingly introduced AI platforms for tasks such as document review, legal research, due diligence and drafting support.
The rollout at Slaughter and May follows a wider wave of AI partnerships and deployments within the legal sector, particularly among large commercial firms seeking to improve efficiency and support increasingly complex cross-border legal work. Neither company disclosed financial details relating to the agreement.
