Explore how CoCounsel Legal helps small law firms nearly double monthly matter capacity while reducing time spent on research, review, and drafting.
Highlights
- Small law firms are rapidly increasing matter capacity and efficiency with CoCounsel Legal’s AI-powered tools.
- CoCounsel Legal enables significant time savings, improved work quality, and reduced professional risk for small practices.
- The 2026 TEI study reveals measurable business benefits and competitive advantages for small firms adopting legal AI.
There is a version of the AI story that treats small law firms as an afterthought – as if the benefits of legal AI only materialize at scale. The data from the 2026 The Total Economic Impact™ of Thomson Reuters CoCounsel Legal Cost Savings and Business Benefits Enabled By CoCounsel Legal study says otherwise.
Small law firms are not waiting for the enterprise version of legal AI. They are already using it to take on more work, reduce risk, and compete for clients that once assumed only larger firms could serve them efficiently.
If you are evaluating whether AI makes sense for a practice your size, these numbers are worth understanding before you make a decision.

What does CoCounsel Legal do for small law firm matter capacity?
The economics of a small practice are unforgiving. Every hour lost to non-billable AI legal research, document review, or drafting rework is revenue that never existed and capacity that cannot grow. When that time gets recovered and redirected into client matters, the effect compounds quickly.
The 2026 TEI study’s findings on matter capacity make that story concrete:
- Small firm respondents went from handling an average of 10.5 matters per month to 18.6 – a 77% increase in capacity without adding a single new hire.
- 70% of small firm respondents said CoCounsel Legal enabled their organization to increase caseload or revenue capacity.
- 82% reported measurable time savings.
- Respondents agreed CoCounsel Legal reduced up to one-third of the time spent on core legal tasks — research, review, and drafting.
- Forrester modeled a payback period of under six months, based on aggregated data from real firms with that recovered time flowing back into billable work.
For a practice evaluating AI adoption, these are not projections for large-firm deployments. They reflect what small firm attorneys are actually experiencing.
Competing up: the strategic case for small firms
The traditional constraint for small practices has always been straightforward: to take on more work, you hire. To deliver at the same level as a larger firm, you need more people. CoCounsel Legal changes both of those assumptions – which is why how drafting and research are delivered matters as much as the headline capacity numbers.
As one partner in labor and employment described in the study:
CoCounsel Legal allows us to stay competitive with bigger firms, without hiring more people to do more work.
Sophisticated clients now expect their firms to use AI tools that deliver faster, more consistent legal work. For small firms, demonstrating that capability — backed by a platform built for small legal teams — is itself a client acquisition and retention asset.
The study’s findings on quality and competitive positioning reinforce that point:
- 76% of small firm respondents agreed that CoCounsel Legal improved research and drafting quality.
- 63% reported improved client value and marketability.
Better work product, delivered faster, by a team that has not grown – that is a meaningful differentiator in a market where the quality gap between firm sizes is narrowing.
Risk doesn’t scale down at a small firm
At a large firm, a compliance gap or an AI governance failure gets absorbed by a risk department. At a small practice, there is no risk department. The attorney’s reputation, license, and livelihood are directly on the line if something goes wrong.
That reality makes the question of AI content quality and professional reliability especially important for small firms. CoCounsel Legal is built on Westlaw, Thomson Reuters’ authoritative legal research database – which is why interviewees in the Forrester study described having a fundamentally different level of confidence in its outputs compared to general-purpose AI tools:
Because CoCounsel Legal is backed by Westlaw, I have a level of confidence and certainty in what it’s doing.
Founding partner, Criminal defense
70% of small firm respondents agreed that CoCounsel Legal reduced professional risk: fewer errors, reduced exposure, and improved compliance. For a practice where every matter reflects directly on a small number of attorneys, that risk reduction is not a secondary benefit. It is fundamental to sustainable growth.
