Advisory — Expert witness

Tribunal, court and arbitration witness work.

Senior-led expert-witness engagement in pensions, insurance and financial services disputes. The firm acts on instruction of solicitors or counsel; for matters where direct counsel engagement is needed, the firm's Bar Standards Board licence permits it. Includes Single Joint Expert appointments, response to expert questions, and trial attendance.

What it is

Senior-led expert evidence under three concentric professional anchors.

The firm makes its pension experts available for expert-witness instruction. Appointments are made to named individuals who carry the duties to the court personally. Each named Expert acts under TAS 100 (FRC General Actuarial Standards), APS X3 (IFoA standard for actuaries as experts in legal proceedings), and the rules of the receiving court — CPR Part 35 civil, FPR Part 25 family, or equivalent for tribunal and arbitration. The Statement of Truth warranties compliance with all three. Fees are not linked to the outcome of the proceedings.

Institutional architecture supports the engagement: FCA authorisation (FRN 831289), Bar Standards Board licence for direct counsel engagement, PI cover through Pembroke Managing Agency Limited with Hamilton Syndicate 4000. The Fair Value Framework methodology, Congruent Quality Framework, and the platform’s calculation control IDs supply the technical apparatus the report rests on — the methodology layer is established by the firm’s wider practice, not invented for the instant case.

Engagement types

Five ways the firm is instructed.

Single Joint Expert
Appointed by joint instruction of the parties (typically through their solicitors) for an independent valuation or actuarial opinion. SJE appointments are made to named individuals; the firm makes its pension experts available across matrimonial pension matters, scheme-funding disputes, sponsor-trustee disputes, and other contexts where joint appointment is appropriate.
Party-instructed
Engaged by one party’s solicitors or counsel to produce an expert report supporting the party’s position. The firm’s reports apply the same methodology and produce the same CMC artefact regardless of which party instructs — the methodology is not partisan.
Counter-expert / methodology challenge
Engaged to review and respond to an opposing party’s instructed expert report. The firm’s well-tested methodology supplies the apparatus on which to challenge or confirm the opposing methodology. May include written response, deposition, or trial attendance.
Response to expert questions
Where the firm’s report is challenged through expert questions (Civil Procedure Rule 35.6 or equivalent), the firm responds in writing within the period specified by directions, grounded in the firm’s methodology and the platform’s calculation control IDs.
Trial attendance and cross-examination
Where the appointed expert is required to give oral evidence and submit to cross-examination, the same partner who drafted the report attends. Counsel briefing meetings in advance of hearing where appropriate.

Matter-type specialisms

  • Matrimonial pension valuations — for routine SJE work, the productised Pension Sharing Order Solution is the right shape.
  • Scheme-funding and sponsor disputes — section 75 debt valuations, sponsor-trustee disputes, contingent-asset valuation, scheme-restructuring challenges.
  • Redress and mis-selling matters — methodology challenges in DB transfer claims, FOS appeals, group litigation. Symmetric DB/DC methodology supports redress defence at scale.
  • Pension liability disputes — IAS 19 challenges, sponsor accounts disputes, longevity assumption disputes in M&A or sponsor restructuring.
  • Insurance and reinsurance matters — actuarial reserving disputes, regulatory enforcement matters, contingent claims valuation.
Engagement and pricing

Scoped through a first conversation.

Fixed-fee engagement

For well-defined scope: SJE appointments, party-instructed reports against an established matter, response to expert questions on a previously-prepared report. Fee agreed at scoping; engagement letter sets timing and named individuals on both sides.

Time-and-materials

For matters where scope evolves: counter-expert work where the opposing methodology disclosure is still developing, trial attendance where days are uncertain, complex disclosure-heavy matters. Rate agreed at scoping; the senior-led approach means the same partner runs the work throughout.

Statement of Work — how the fee is fixed

Engagements are scoped through a first conversation and then fixed in writing before any work begins. The firm’s Invitation Letter contains a Statement of Work fixing: the scope of the engagement, the timetable for delivery (key milestones and final-deliverable date), the price (with any stage payments scheduled against milestones), and the named individuals on both sides.

The scope-to-price conversion is based on the firm’s published charge-out rate: £350 per hour for engagements led by a Director or Senior Actuary (the only grades that lead engagements at Congruent). The Statement of Work converts scoped hours into a fixed fee — the buyer’s commercial commitment is to the fee in the Statement of Work, not to an open-ended hourly meter.

The firm tends to come in competitively on the fixed quote. Because Directors lead engagements directly — without the layered team structure typical of larger firms — scoped hours convert into a fixed fee that compares favourably against equivalent senior-led work elsewhere in the market.

Rate as at 1 January 2026, reviewed annually.

Expert witness instruction

Every expert-witness engagement begins with a scoping conversation.

If the matter requires actuarial or financial-economics expert input, the firm responds within one working day with whether it can take the instruction, what conflicts (if any) apply, and what it would need to scope the work. No pre-qualification questionnaire; the first call is the scoping discussion.
