Sorren has launched affiliated legal practice Sorren Law using a lawyer-owned law firm and a separate management-services organisation, as accounting and advisory groups continue to explore new structures for expanding into legal services.
Sorren Law has been formed from Mansfield & Mayo, a Nevada and Idaho-based law firm led by attorneys Patrick Mansfield and Massey Mayo. The practice offers services including corporate and business law, mergers and acquisitions, commercial transactions, estate and succession planning, asset protection, tax planning, litigation and dispute resolution.
The ownership structure is central to the arrangement. Sorren Law is separately constituted and regulated and is owned exclusively by lawyers. It remains legally distinct from Sorren Inc., the accounting and advisory business.
Administrative and operational support is instead provided through Sorren Legal Support, a subsidiary of Sorren Inc., under a management-services agreement. Sorren chief executive Josh Tyree told Reuters that Sorren and lawyers at Sorren Law are co-invested in the management-services organisation.
Sorren states that Sorren Legal Support is not a licensed law firm, does not provide legal advice and cannot direct, regulate or influence the legal services supplied by Sorren Law. Attorney-client relationships exist solely between clients and the law firm.
That separation is significant because SRA Disqualifies PM Law’s Bostock — Lawyer Monthly in most US jurisdictions restrict non-lawyer ownership of law firms. Management-services organisations provide one possible structure for separating the practice of law from the technology, administration and other non-legal assets supporting a legal business.
The distinction is particularly important where SRA Consults on Third-Party Litigation Funding Rules is involved. Sorren itself is backed by private equity firm DFW Capital Partners, but Sorren Law is not owned by Sorren or DFW. The investment relationship instead sits around the wider professional-services group and the separate support organisation.
For lawyers considering similar structures, ownership is only one part of the regulatory analysis. The commercial relationship must also preserve lawyers’ independent professional judgment, confidentiality obligations and control over client representation.
That places particular importance on the management-services agreement. It determines which administrative functions are supplied by the MSO, how the relationship operates and where the boundary between commercial support and legal decision-making is maintained.
Sorren says the arrangement will allow Sorren Law to benefit from the wider group’s investments in technology and other capabilities without transferring ownership or control of the legal practice to the accounting business.
The model also reflects increasing convergence between legal, accounting, tax and advisory services. Clients involved in acquisitions, succession planning, business restructuring or wealth management can require several types of professional advice around the same underlying decision.
Sorren Law’s founding practice already works with businesses, investors and individuals, while Sorren says further geographic expansion is planned. The wider Sorren group was formed in 2025 through the combination of 13 accounting firms and now employs more than 1,000 people.
For the legal industry, the more significant question is whether structures of this kind can deliver closer commercial integration without weakening the regulatory separation required between lawyer-controlled legal practice and non-lawyer businesses.
Sorren Law therefore adds another model to the developing US market for multidisciplinary CILEX Calls for Legal Services Act Review | Lawyer Monthly: a lawyer-owned firm connected to a larger accounting and advisory platform, with the commercial infrastructure housed in a separate management-services organisation.
