Court reports · digital forensics in Cardiff

Expert witness reports, Cardiff. Written for the court first, our weak spots included.

Under CPR Part 35 an expert works for the court before anyone else — before the client, before the solicitor, before whoever is paying. The solicitors and insurers who instruct us, in Cardiff and across South Wales, have all seen what a partisan report does under pressure: it folds as soon as somebody competent tests it. Our reports begin from that rule.

The parts a court report cannot leave out.

The expert's first dutyPart 35 casts the expert as a help to the court, speaking only where they hold real competence, and that obligation beats whatever the instructing party hoped to be told. It goes at the top of the report, and everything that follows is measured against it.
Truth and complianceThe report separates out the facts the expert knows at first hand and holds to be true, records that the opinions given are genuinely held with nothing kept back, and confirms that it complies with Part 35 and the practice direction sitting under it.
How it was done, and to whatArrival, imaging, the hash values, the examination, and the exhibit's whereabouts at each stage — referenced tightly enough that an examiner on the other side could repeat the lot.
Our own weak pointsThe criminal rules have since 2019 required an expert to declare anything touching their credibility, and an accreditation not held is named outright. Ours sits in the first few pages, a long way from the footnotes.

Five reports, and where each belongs.

01

A private scoping call first, then a written price Free

It starts with a private conversation, and that costs nothing. Three things shape everything after it: what has happened, where it reaches — which machines, which accounts — and what the evidence needs to establish. Those answers set the scope. The scope sets the single written price, quoted before a device is touched.

Kept confidentialOne fixed figure in writingWhat the evidence must show
02

On the record from the start

Your letter of instruction is summarised in the report, in our words. Beside it sits anything bearing on our credibility — starting with the fact that this is an independent lab without accreditation. Better on the page at the outset than prised out of us under cross-examination.

Instructions recordedWeak points declared early
03

Assume someone will attack it

Every step is done, and written down, as though the examiner on the other side were already reading it — hunting for the loose joint, which is what they are paid to do. Conclusions do not lean towards whoever is paying.

The court comes firstFindings that hold their shape
04

Shaped to the right rules

The forum sets the format — CPR Part 35 in civil matters, CrimPR Part 19 in criminal ones. Both routes give you the method on paper, the exhibits, a continuity record without a break in it, and the two declarations. Conclusions lead; the technical detail sits in an annex at the back.

The whole bundle, hashes and all

A report is only worth what someone else can check, so it never travels alone. Out go the exhibits, the source files, the continuity log, every hash value, and the notes made at the bench. An expert instructed against you can walk it again and reach the same place.

Notes from the workbench

  • Everything turns on the overriding duty — when the court's needs and the client's needs point in different directions, the court wins, and a report drafted without grasping that is finished before it is read.
  • Criminal cases need the reliability material — a bench cannot weigh an opinion until the qualifications and the experience behind it are written down.
  • A joint instruction changes the maths — instructions from both parties, a single examiner, no one to keep sweet. We take that work on, and say so at the outset.
  • Readability counts as much as rigour — a report a judge has to decode does not do its job, however careful the examination underneath it was.

Ask any expert you are weighing up this one question: the criminal practice directions have expected, ever since April 2019, that anything capable of undermining an expert's reliability is disclosed, and the absence of an accreditation is offered as an example. Kept quiet, the problem stops being theirs and becomes yours. Ours is declared on page one of every report we send out.

Straight out of the casebook.

Two Monmouthshire firms, one folder, and a Part 35 report

Two firms, one shared folder, and two sets of accounts that would not match. The image showed neither copy had been left untouched, and the timeline made that impossible to dispute. It was over inside a month.

Closed post-exchangeCPR 35 compliant

Before you send it off.

Start with these

  • Tell us straight away if a court might see it — the method changes
  • Get the letter of instruction over to us early
  • Pass on anything the other side's expert produces
  • Allow weeks rather than days; this is not work that can be hurried

What to avoid

  • Press for a conclusion the evidence will not bear
  • Edit our wording — argue with the reasoning instead
  • Expect Part 35 work turned round in days
  • Shop around for an expert who agrees in advance; it shows

The things people ask on the phone.

What does a court report add to a plain findings report?

A findings report covers two things: what we found, and the route we took to it. A court report carries all of that plus the overriding duty, a summary of your instructions, the whole method and exhibit history, signed statements of truth and compliance, and every point an opponent might raise about the expert.

Who is the expert acting for?

The court, whoever pays the invoice. That duty sits above anything owed to the side that instructed us, and it is precisely that ranking which gives the report its value.

Do you accept single joint expert work?

Yes. There is one report and one set of conclusions. Both parties receive it at the same moment, and neither gets a preview or a chance to shape the wording.

Does the lack of accreditation count against you?

The rules require it to be declared, so we put it near the front rather than in small print at the back. What a court tests is the method, and that is where an opinion earns its weight. Reports come apart when they overreach, not when a certificate is absent.

That recorder is still writing over it.

While that recorder keeps writing, the clip you need is being covered over — and your deadline has not moved. Book it in. The first look is free, and it stays private.
