Law firms enjoyed one of their busiest quarters ever in the third quarter of 2026, with rates holding at all-time highs and productivity in the black; however, multiple factors worked to either suppress performance or build to a warning. The Law Firm Financial Index¹ (LFFI) fell six points in Q3 2026 to a score of 54, close to the index’s historic average score.

‍

The primary culprit pulling down the LFFI was spending. Direct expenses ended the quarter growing at the fastest pace of any quarter in the past two years on a rolling 12-month basis. Overhead expenses were not far behind, just shy of their own recent peak. Demand, meanwhile, had its bright spots. Growth of 3.2% on a weekday-adjusted² basis made Q3 the strongest quarter for demand so far in 2026. And that’s despite measuring up against the heights of Q3 2025.

‍

Breaking down where demand is coming from reveals further trouble spots among otherwise positive signs. Labor & employment was the fastest-growing practice in Q3, followed by corporate work, litigation, and bankruptcy. The makeup of the top four fastest growing practices is telling. Labor & employment, litigation, and bankruptcy are all counter-cyclical³ practices, which posted a combined 3.4% weekday-adjusted growth in Q3. Transactional work was slightly more muted, growing by 2.8%, which is still very solid; however, this is the first time in two years counter-cyclicals have pulled this far ahead of transactional performance. Thus, firms are busy, but the balance of their work is tipping towards an economic environment of uncertainty rather than one of confidence.

‍

The direction that demand took over the course of the quarter adds further reason for concern. July and August were the strongest months of the third quarter, and for a time it appeared that the quarter might match or even surpass the 3.7% weekday-adjusted growth seen in Q3 2025. September told a different story, however, as demand slowed meaningfully, resulting in 3.2% growth for the quarter.

That said, the slowdown should not overshadow the broader picture. Between Q1 2023 and Q2 2025, weekday-adjusted demand growth never exceeded around 2.4%. Since Q3 2025, however, every quarter has come in at 2.8% or higher. In other words, what once would have been a standout quarter has become the norm, and a 3.2% finish after a September dip remains unusually strong even by recent standards. Combined with rate growth that’s holding at above 7%, overall revenue growth remains extraordinarily strong and is outpacing expense growth, albeit by a declining degree, especially as hiring season kicks into gear.

‍

Speaking of which, rising associate pay is a major reason why direct expenses are now growing at their fastest pace in two years, although for once the top law firms are not leading the charge. The top 200 Am Law firms held to last year’s growth pace or were even slightly lower, while midsize firms accelerated the pace of their associate pay significantly, nearly doubling 2025’s pace and tripling that of 2024. This could become an issue clearly, as midsize firms are the least well positioned to afford such costs given their slower rate growth.

‍

Meanwhile, overhead expenses per lawyer grew 5.8% in Q3, with most of the push coming from a now familiar source. Higher technology spending accounted for 1.3 percentage points of firms' total growth in overhead per lawyer. Put more simply, if a firm spent $100 per lawyer on overhead a year ago, it now spends $105.80, and $1.30 of that additional $5.80 went to technology alone.

Still ahead of the curve

To put the third quarter in perspective, it helps to compare it with the two periods that have delivered the best results for law firms in recent memory: Q3 2021 and Q3 2025. The transactional boom was the product of unusual conditions, as pandemic-era government stimulus and near-zero interest rates made credit cheap and plentiful, while deals delayed during the early months of the pandemic rushed to market at once. Demand for transactional work soared, and firms rode that wave to record results. In Q3 2025, extreme geoeconomic tension and AI frenzy fed law firm demand and pushed profits to record levels.

Interestingly, Q3 2026 earns a lower LFFI score than either period despite comparable profit growth. Why? Because compared to last year, expenses now are growing at somehow an even hotter pace, while current expense growth is twice that of Q3 2021.

‍

However, revenue is coming into the door so fast it may be difficult for firms to care, as shown by their margin expansion.⁴ All three law firm segments continued to widen their margins in Q3: the Am Law 100 by 3.6 percentage points, the Am Law Second Hundred by 1.8, and midsize firms by 1.4 year-over-year. Compared to where things stood in 2025, the Am Law and midsize firms are in a stronger position, with midsize firms improving from a slight contraction in Q3 2025. However, in another sign of a darker turn that may be in the wings, margin gains narrowed in every segment from Q2 to Q3. That means profits are still growing faster than revenue, but by a smaller degree than just three months ago.

‍

In total, Q3 2026 was a quarter of contrasts. Demand reached its best level of the year, fueled by counter-cyclical work, yet the LFFI fell as direct and overhead expenses accelerated. Even so, firms are in a healthier position than the score alone suggests as profit growth continues to outpace expenses, and margins are still widening in every segment.

The challenge heading into Q4 is a familiar one for firms – the numbers work so long as revenue growth continues to be historically strong. Should that falter in the fourth quarter, the LFFI could fall far below the middling score at which it currently sits. In other words, the LFFI is doing as it did when it dropped 17 points following the industry’s Q3 2021 heights: offering a warning.
