A court-ordered expertise follows a strict framework. The judge appoints an expert, sets their brief, and the parties file their observations to an imposed timetable. A client left alone in this process rarely appreciates the weight of each meeting and each technical note.

We stand alongside you throughout. We help prepare your submissions, flag points the appointed expert has not examined, request the further investigations needed, and check that your technical arguments are properly on file.

We also act upstream, to prepare a case: recording defects, costing the loss, assessing the technical strength of a claim. Many disputes are settled this way before the hearing, which remains the least costly outcome.

Situations we deal with

The court has ordered an expertise

We accompany you to the meetings, take note of the findings and formalise your observations within the deadlines set.

You are considering suing a contractor

We first produce a full technical record of the defects and a costing, so the claim rests on solid ground.

The appointed expert's report seems incomplete

We identify missing investigations, unverified assumptions and any heads of loss that have been overlooked.

A defect threatens safety

Partial collapse, significant cracking, a weakened structure. We inspect quickly and set out the safety measures to take.

Several contractors are blaming each other

We allocate the causes by trade, which lets the case move forward instead of going round in circles.

Why call in an expert

Your technical arguments are heard

A clear note, submitted at the right time, carries more weight than an objection raised verbally at the end of a meeting.

Nothing important is missed

Heads of loss, secondary defects, temporary works, consequential impacts. We check the full scope has been examined.

You keep control of the timetable

We track the deadlines of the expertise and alert you to what needs to be submitted, and when.

Unsure about your building? Have it assessed.

    First contact

    We review the brief set by the judge, the timetable and the documents already filed.

    Report and follow-up

    We hand our technical conclusions to your lawyer and remain involved until the final report is filed.

The expert report

Documents we produce in a court context follow the logic of the brief: each question raised receives a distinct answer, supported by identifiable findings and referenced documents.

This format makes life easier for your lawyer and for the judge. It also reduces the risk of a conclusion being dismissed for lack of sufficient support.

What the report contains

  • Point-by-point answers to the brief
  • Dated, located and photographed findings
  • Critical review of documents from the other side
  • Detailed costing of repairs and losses
  • Further investigations proposed

Frequently asked questions

The judge appoints the expert in their decision and sets the brief. The parties may suggest names, and above all they can discuss the content of the brief, which determines the scope of the work.

Yes, and it is strongly advised. You can be accompanied by your lawyer and by a technical expert who represents your position during the meetings.

From a few months to more than a year, depending on the complexity of the case, the number of parties and the investigations required. A well-prepared technical file at the outset noticeably shortens the process.

A deposit is usually paid by the claiming party. The final allocation of costs is decided by the judgment, depending on the outcome of the dispute.

Often, yes. A clear technical report can lead to a negotiated settlement and avoid lengthy proceedings. We favour this route whenever it remains possible.

Yes. We review the final report, identify what can be challenged and support your lawyer through the rest of the proceedings.
