Evidence & investigations · expert witness & reports

Our duty is to the court. Even when you’d rather it wasn’t.

An expert report isn't advocacy with exhibits. Under the civil rules, the expert's duty to the court overrides any obligation to whoever instructs or pays — and a report that forgets that is worth less than no report at all. We write ours accordingly.

What a court-ready report contains.

The duty, stated and meantCivil experts help the court on matters in their expertise — a duty that overrides any obligation to the instructing or paying party. It's the first thing the report says and the standard everything else is held to.
Statements of truth and complianceThe report confirms which matters are within the expert's own knowledge, that those are true, and that the opinions given are complete professional opinions — with compliance with Part 35 and its guidance confirmed.
Methodology and chain of custodyWhat was received, how it was imaged, hashed and examined, and where every exhibit has been — referenced so another expert can retrace it.
Disclosure — including oursCriminal procedure has, since 2019, required disclosure of anything bearing on an expert's credibility, expressly including lack of accreditation. Ours is stated up front, every time.

01

Scoped in confidence, quoted in writing Free

Every instruction starts with a confidential conversation: what happened, which devices and accounts exist, and what question the evidence needs to answer. You get a fixed written quote before any examination begins — and the initial scoping costs nothing.

Confidential scopingFixed written quoteClear question defined
02

Instruct and disclose

Instructions are recorded and summarised in the report; anything bearing on credibility — including that we are an independent, non-accredited lab — is disclosed before a word of analysis is written.

Instructions on the recordStatus disclosed up front
03

Examine to the duty

The examination is run and written up as if the other side's expert were watching — because eventually, they are. Findings read the same whichever party instructs us.

Report to the rules

The report is built to CPR Part 35 or CrimPR Part 19: methodology, exhibits, chain of custody, statements of truth and compliance — and plain English above the technical appendix.

Delivered, preserved, defensible

You receive the findings — report, exhibits and supporting files — with hashes, continuity records and our contemporaneous notes preserved. If the work is ever tested by another expert or a tribunal, the trail is there to be followed.

What the lab holds to

  • The duty clause isn't boilerplate — civil rules put it bluntly: the expert's obligation to the court overrides any obligation to whoever instructs or pays.
  • Criminal reports must carry reliability information — qualifications, experience, and anything the court needs to judge whether the opinion is dependable.
  • Single joint experts change the geometry — one expert, two parties, no cheering section. We take those instructions.
  • Plain English is a compliance feature — a report the tribunal can't follow helps nobody, whatever its appendix says.

The disclosure rule worth knowing before you instruct anyone: since April 2019, criminal procedure directions have required parties to disclose matters capable of undermining an expert's reliability — with lack of accreditation named explicitly. Any expert who buries that is building your case on sand. Ours goes on page one.

A Part 35 report that shortened a Sussex dispute

Two businesses, one deleted folder, two theories. The imaged drive supported neither side's favourite story — and said so, with the timeline to prove it. The matter settled within a month of the report being exchanged.

Settled post-exchangeCPR 35 compliant

Before it reaches us.

Do

  • Tell us at instruction if court is possible — it shapes everything
  • Share the letter of instruction early
  • Give us the other side's expert questions when they exist
  • Allow time: rigour reads slowly and writes slower

Don't

  • Ask for conclusions before the evidence supports them
  • Edit findings — challenge them instead, on the evidence
  • Instruct late and expect Part 35 by Friday
  • Shop for an expert who'll 'say the right thing' — courts notice

Asked in confidence, answered honestly.

What's the difference between a forensic report and an expert witness report?

A findings report states what was found and how. A court report adds the overriding duty to the court, statements of truth and compliance, summarised instructions, full methodology and chain of custody — and disclosure of anything affecting credibility.

Who does an expert witness actually work for?

Formally: the court. The duty to assist the court overrides any obligation to the instructing or paying party — which is precisely what makes a compliant report worth having.

Can you act as a single joint expert?

Yes — where the court directs a single joint expert, we report to both parties on identical terms, which tends to concentrate everyone's minds.

Will your non-accreditation be a problem in court?

It will be disclosed, as the rules require — and weighed alongside methodology, which is where reports actually live or die. What sinks experts is overclaiming; we don't.

Evidence doesn't wait. Neither should you.

Loops overwrite, artefacts age, deadlines pass. Open a case first — the scoping conversation is free and confidential either way.
