Professional service firms — law firms, accountancy practices, consultancies, architects, surveyors — sit in a peculiar place for directors and officers cover. The firm-level regulatory regime (SRA for solicitors, ICAEW for chartered accountants, RICS, ARB) already imposes personal duties on principals, and the LLP structure that most firms use has its own personal-liability mechanics for designated members. This entry sets out how D&O responds where professional-body enforcement escalates against an individual, where partnership and LLP disputes sit, and how D&O aligns with the compulsory professional indemnity that these firms already carry.
Partnership disputes are the most common trigger. Where an equity partner leaves under contested circumstances, brings a claim for underpayment, or is expelled, LLP designated members and management-board members can be named personally. The Limited Liability Partnerships Act 2000 and the LLP Regulations 2001 impose the fiduciary and duty-of-care obligations on members, and the LLP agreement usually adds further personal warranties.
Professional-body enforcement is the second head. SRA prosecutions of principals of solicitors’ firms before the Solicitors Disciplinary Tribunal, ICAEW disciplinary proceedings against members, RICS disciplinary hearings, and ARB Professional Conduct Committee hearings all attach to the individual. Where the individual is also a director or LLP member, the defence of the personal position sits within the D&O tower’s remit (subject always to the wording of the ‘insured person’ definition and the ‘wrongful act’ trigger).
Exit-strategy claims — M&A of a professional service firm, consolidation into a larger group, sale to a private equity house — produce warranty and indemnity disputes that name the sellers personally. The disclosure schedule is exhibit one.
Side A covers the individual director or LLP designated member when the firm cannot or will not indemnify. Side B reimburses the firm for indemnifying its principals. Side C responds to securities claims for firms with external equity investment or listed holding structures. Extensions worth attention are pre-claim investigation costs for regulator enquiries, employment practices liability for partner disputes framed as employment claims, and outside directorship cover for firm principals sitting on client or industry-body boards.
Deliberate dishonesty and improper personal profit are excluded once established by final adjudication. Prior known circumstances are excluded — and given the depth of documentation in professional service firms, the proposal-form disclosure obligation is broad. Bodily injury and property damage sit on other policies. Fines and penalties that are not insurable as a matter of English public policy fall outside. Claims by one insured against another are excluded save for standard carve-outs; partnership disputes are usually the reason those carve-outs matter.
Limited Liability Partnerships Act 2000 and Limited Liability Partnerships Regulations 2001 (applying Companies Act 2006 duties, modified, to LLP members). Companies Act 2006 sections 171-177 for corporate practices. Legal Services Act 2007 for solicitors’ and ABS firms. Solicitors Regulation Authority Code of Conduct 2019 and SRA Standards and Regulations. ICAEW Code of Ethics and Disciplinary Bye-laws. RICS Rules of Conduct 2022. Architects Act 1997 and ARB Standards. Insolvency Act 1986 sections 213-214 (and equivalents for LLPs under the LLP Regulations). Insurance Act 2015 sections 3, 7 and 8. Company Directors Disqualification Act 1986 (extended to LLPs).
Professional service firms carry compulsory PI: solicitors under the SRA MTC, accountants under ICAEW / ACCA regulation, surveyors under RICS, architects under ARB. PI covers the firm’s work for its clients — negligent advice, missed deadlines, drafting errors. D&O covers how the firm was run — management decisions, partner conduct, financial disclosures, personnel actions.
The overlap is real: a client complaint about advice can escalate into a regulator investigation of the individual partner, which is a D&O trigger, while the underlying negligence sits with PI. A specialist broker aligns the wordings so that when both towers are engaged the definitions co-operate, the notification triggers do not conflict, and the retro-dates do not leave a gap.
An LLP expels an equity member following a governance dispute. The expelled member brings a claim under the LLP agreement alleging unfair prejudice, wrongful expulsion and breach of the section 172 (as modified for LLPs) duty by the management-board members. The four management-board members are named personally. Legal defence of their personal position through the pre-action correspondence, mediation, and any subsequent High Court proceedings runs on the LLP’s D&O tower. Side A responds where the LLP agreement does not permit indemnification of the specific loss; Side B reimburses the LLP where indemnity is provided. The insured-versus-insured exclusion is carved out for member-versus-member claims of this type — and the wording of that carve-out is the difference between cover and no cover.
D&O policies are claims-made. Where a professional-body enforcement letter, a member-versus-firm claim, an M&A warranty demand or a large client-driven complaint escalation lands during a policy year, that circumstance needs to reach the broker before the year ends. Late notification is the single most common reason a D&O claim gets declined. The three triggers to watch for are a written demand or proceeding, a regulatory investigati
