Expert evidence is often the single factor that determines whether a housing disrepair claim resolves quickly or ends up contested. Yet in many firms, the expert’s report is still handled as a document that arrives, gets reviewed, and gets filed, sitting outside the case management workflow rather than built into it.

The role of the expert

In housing disrepair claims, the surveyor’s role is to provide an independent, professional opinion on the condition of a property and the cause of any disrepair, typically a chartered surveyor, often RICS-qualified (Royal Institution of Chartered Surveyors), instructed specifically for that purpose.

Under Part 35 of the Civil Procedure Rules, an expert witness’s overriding duty is to the court, not to the party instructing them. That distinction matters: surveyors acting on a case are not advocates for the claimant or the landlord, and expert witness reports are expected to reflect independent professional judgement, not the instructing party’s preferred outcome.

This principle isn’t unique to housing disrepair. The same Part 35 framework governs expert evidence across civil litigation, from property condition disputes through to claims involving life-changing injuries, where expert input often extends into social care needs assessment alongside medical evidence.

The common thread is that expert evidence carries weight in legal proceedings precisely because it is independent, which is exactly why it needs to be handled correctly from the point of instruction.

Why this needs to sit inside the workflow, not beside it

Once expert evidence is on the file, it should support the wider case, not exist as a standalone attachment. Two issues typically arise when it doesn’t:

1. No clear record of why the expert was instructed. Part 35 compliance depends on being able to show that instruction was justified and proportionate. Without that reasoning captured at the time, firms are reconstructing their justification later, a weaker position in dispute resolution or at assessment.
2. No link between the report and the wider evidence timeline. An expert’s findings are most persuasive when they sit alongside the landlord notification date, correspondence, and any earlier evidence, not disconnected from it.

Building it into the workflow properly

A workflow that handles expert evidence well captures the instruction decision and its justification at the point it’s made, links the resulting report directly to the case timeline, and prompts consideration of whether expert evidence is proportionate before it’s commissioned.

Handled this way, expert evidence stops being paperwork attached to a case and becomes a properly integrated part of it, auditable, defensible, and ready to support the claim wherever it needs to.
