What In-House Teams do With the Capacity Legal AI Creates

In-house legal teams rarely have the luxury of a lighter workload. As contract volumes grow, regulations change, and the business moves faster, Legal is expected to keep pace without proportional increases in headcount or budget. Strategic work competes with a steady flow of urgent requests, leaving less time to advise the business before decisions are made.

Legal AI is helping teams create capacity within these constraints. Recent RSGI research found that 92% of surveyed in-house legal teams using Harvey report faster turnaround of legal work to the business.

The larger impact comes from what teams do with that capacity: 88% are spending more time with the business on higher-value work, and 53% are spending more time advising on strategy and new products. Across legal departments, AI is opening up new choices about where lawyers focus their attention, how work is allocated, and where outside counsel adds the most value.

Keep Pace With Growing Demand

For many in-house teams, the time AI saves is quickly claimed by work that was already waiting. New regulations, business expansion, and rising contract volumes continue to generate more legal requests, often without corresponding increases in headcount or budget.

In RSGI’s report, 68% of in-house legal teams expected their headcount to remain flat over the next year. AI is helping existing teams keep pace by reducing the time required for high-volume work. Ninety-one percent of teams reported saving time on contract review, while 80% reported savings on repeatable workflows.

At ASML, a Dutch semiconductor company, the legal team used a Harvey agent to automate part of a data protection impact assessment process that previously required employees to navigate a privacy tool manually. During a period of regulatory pressure, its employment specialists also handled close to 1,000 queries in a single month without adding headcount.

For teams facing a steady increase in demand, added capacity from AI can mean shorter backlogs, faster responses to the business, and greater flexibility when priorities suddenly shift.

Expand How Legal Supports the Business

High volumes of routine work can keep legal teams in a reactive position, responding to individual requests without enough time to understand the broader business context. RSGI’s research shows where teams are beginning to regain that time: among surveyed in-house teams using Harvey, 91% have reduced the time spent reviewing contracts and 80% have saved time on repeatable workflows.

As everyday work takes less time, lawyers can be more available to colleagues and contribute beyond the immediate legal question. At a professional services company, the legal team used Harvey Vault to review contracts and identify revenue the business was missing where annual-uplift clauses were absent. A leader on the team said that contributing to revenue helped the business see Legal as more than a “point solution.”

At Carrefour Spain, the legal team used AI to create self-service tools that allow business colleagues to generate certain contracts and answer common legal questions independently. Giving colleagues a faster path through standard matters lets lawyers focus their time on questions that benefit from deeper collaboration and legal judgment.

Advise Earlier on Strategic Decisions

The value of legal advice often depends on when it arrives. When lawyers are involved early in a product launch, transaction, or market-entry decision, they have more opportunity to understand the commercial goal, identify potential risks, and help the business evaluate its options.

One financial services legal team in RSGI’s research said that time freed through Harvey allowed its lawyers to provide more business advice on strategic commercial issues, including entering new markets and launching new products. More broadly, 48% of surveyed in-house teams expect legal to have a more influential strategic role in the business within the next year as a result of using Harvey.

Earlier involvement gives legal teams more influence while important choices are still open. It also helps the business address risk as part of the decision-making process, rather than after plans are already underway.

Bring More Work In-House

Capacity constraints can lead in-house teams to send work to external counsel even when they have the expertise to handle it internally. By accelerating document-heavy and repeatable work, AI is expanding the range of matters legal departments can realistically take on themselves.

More than a third of the in-house teams surveyed by RSGI (36%) reported bringing in work that was previously handled by external counsel. Repsol, for example, completed a mid-sized M&A transaction in-house using Harvey rather than sending it to a law firm. External quotes for the work averaged €200,000.

Other teams are bringing specific stages of a matter in-house. A US energy company now conducts first-pass M&A diligence in Vault before involving outside counsel, avoiding hundreds of hours of outside-associate time on each deal. As legal teams take on more of the underlying work, they can bring in outside counsel later and with a narrower remit focused on specialized expertise, validation, and high-stakes judgment.

The capacity AI creates gives in-house teams more choice over how work is allocated and when to involve outside counsel. Bringing more work in-house does not eliminate the need for law firms; it gives outside counsel a more focused role reviewing and validating work, advising on consequential issues, and providing specialized expertise. For both in-house teams and firms, more lawyer time can go toward the work where it has the greatest impact.
