Biglaw Office Leasing Surges, Tightening WFH Mandates

• Legal sector office leasing surged 17% in the first half of 2026, reaching nearly 12.2 million square feet, according to Cushman & Wakefield data.
• Biglaw firms have significantly tightened in-office mandates since 2023, with four days a week becoming the new minimum for many.
• Sullivan & Cromwell now requires attorneys to be in the office five days a week, while Duane Morris recently moved to a four-day policy.
• This substantial real estate investment and shift in policy signals a definitive end to widespread remote work flexibility within large law firms.
• The trend impacts talent retention, career decisions, and firm culture, despite associates' stated preference for flexible work arrangements.

These stringent policies, coupled with the expansive office leasing figures, strongly indicate that the era of widespread work-from-home arrangements is receding within the large law firm landscape.

The legal sector has demonstrated a robust commitment to physical office space, with new data revealing a substantial increase in Biglaw office leasing. According to figures from a Cushman & Wakefield legal office report, which were subsequently reported by Reuters, office leasing within the legal sector surged by 17% year-over-year in the first half of 2026, encompassing nearly 12.2 million square feet. This significant expansion underscores a broader trend of Biglaw real estate investment trends, signaling renewed confidence in traditional office environments.

Law firms emerged as a primary driver of demand in the recovering office market, particularly within the 10 major legal markets tracked by Cushman & Wakefield. In the second quarter alone, these firms accounted for 14% of all office leasing activity. David Smith, head of Americas Insights for the Cushman & Wakefield Global Think Tank, noted the sector's optimism regarding its future trajectory, a sentiment reflected in the aggressive acquisition of prime real estate.

This period has seen Manhattan firms engaged in a notable "space race," vying for premium locations and larger footprints. A prime example of this trend is Simpson Thacher & Bartlett's relocation, which involved securing an impressive 916,000 square feet. This deal, identified by Savills as the single largest legal transaction of the quarter, represents a scale of investment that would have been considered unimaginable in 2020, a time when landlords were exploring conversions of office buildings into residential units.

Coinciding with this significant Biglaw real estate investment, large law firms have progressively tightened their in-office mandates, effectively signaling the legal industry remote work end for many. Since 2023, there has been a noticeable shift towards requiring attorneys to spend more days in the office, despite a clear preference among associates for greater flexibility over prestige. This trend suggests firms are leveraging their substantial physical assets by ensuring a consistent presence from their workforce.

The prevailing standard across Biglaw is increasingly a four-day in-office requirement. Duane Morris, for instance, recently escalated its Law firm return to office policy, moving from a three-day to a four-day office week, establishing a Duane Morris 4-day office week. Leading this charge towards full in-person work is Sullivan & Cromwell, which now mandates a five-day in-office requirement for its attorneys, setting a new benchmark for the Sullivan Cromwell in-office requirement.

These stringent policies, coupled with the expansive office leasing figures, strongly indicate that the era of widespread work-from-home arrangements is receding within the large law firm landscape. The substantial financial commitments to physical infrastructure suggest that firms are not planning for a workforce that only occasionally utilizes their office space, reinforcing a strategic pivot back to a more traditional, in-person operational model.

The dual trends of expanding office footprints and mandatory in-office policies carry profound implications for legal talent and firm culture. For lawyers considering Biglaw roles, these developments mean a diminishing availability of remote work options, directly impacting career decisions and work-life balance expectations. Firms must now navigate the challenge of talent retention in an environment where flexibility, once a key draw, is being significantly curtailed.

Firm leaders are grappling with a complex array of factors, as highlighted by new executive research from Ari Kaplan. This research explores how law firm leaders are responding to evolving client expectations, changing economic landscapes, talent transformation, and the burgeoning challenges of AI governance. The push for mandatory in-office work, therefore, is not an isolated decision but part of a broader strategic response to these multifaceted industry shifts.

Ultimately, the current trajectory suggests that future talent acquisition strategies will need to account for a firm culture increasingly centered around physical presence. The emphasis on in-office collaboration and mentorship, driven by these Biglaw office leasing WFH mandates, will shape employee satisfaction and the overall appeal of large law firms, potentially requiring new approaches to attract and retain top legal professionals in a competitive market.

This trend signals a significant shift towards mandatory in-office work for lawyers in large firms, impacting career decisions, work-life balance, and talent retention strategies. Lawyers considering Biglaw roles or firm leaders planning future talent acquisition should factor in the diminishing availability of remote work options and the associated implications for firm culture and employee satisfaction.
