Evidence and the Legal Issues
| Issue | Typical evidence |
|---|---|
| Duty and defendant | Referral, appointment, admission, provider and contractual records |
| Breach | Clinical records, imaging, test results and independent expert report |
| Causation | Earlier and later records, scans, pathology, timeline and expert report |
| Injury and future needs | Treating records, examination and condition/prognosis evidence |
| Financial loss | Payslips, receipts, invoices, mileage and care evidence |
For the legal framework, read what counts as medical negligence.
Medical Records
Relevant records may include GP and hospital notes, observations, medication charts, referral letters, test results, imaging, pathology, consent documents, operation notes, maternity records, ambulance records and rehabilitation notes. A delayed diagnosis case may require records from before and after the alleged delay.
Records are not infallible. An entry may be incomplete, ambiguous or disputed. Missing detail does not automatically prove negligence, and a signed consent form does not by itself prove that an adequate discussion occurred.
Your Chronology and Witness Evidence
Write a factual chronology while events are fresh. Record dates, symptoms, advice, treatment and changes in condition. Mark uncertainty rather than guessing. Witness evidence may explain conversations, visible symptoms and the day-to-day effect of injury, but it cannot replace expert opinion on technical medical questions.
Keep complaint responses, investigation material and duty-of-candour correspondence. They may be relevant but do not automatically determine civil liability.
Independent Medical Experts
The expert must have suitable expertise for the question. A GP expert may address referral, a surgeon operative technique and a radiologist image interpretation. A separate expert may address causation, condition and prognosis. Complex claims can require several disciplines.
An expert’s duty in court proceedings is to assist the court independently, not to guarantee a case. If the evidence does not support breach or causation, the solicitor should explain that honestly.
Evidence of Injury and Financial Loss
Keep documents showing earnings and pension loss, treatment and therapy costs, travel, equipment, adaptations, paid support and unpaid care from family or friends. A care diary should record the task, time and frequency without exaggeration.
Read how medical negligence compensation is assessed.
What the Defendant May Argue
A defendant may say the care represented a responsible approach, the complication occurred without negligence, earlier action would not probably have changed the outcome, some loss came from the underlying illness, or the claim is out of time. Evidence should answer the actual disputed issue rather than simply be accumulated.
Evidence Checklist
- provider, hospital, clinic and clinician names;
- key dates and a short chronology;
- records across the relevant period;
- imaging, pathology and test results where relevant;
- complaint and investigation correspondence;
- witness names and what each person directly observed;
- current treatment and prognosis material;
- receipts, earnings evidence and a care diary; and
- the possible limitation date flagged for urgent advice.
Do not alter records, dispose of original packaging, access another person’s records without authority or delay urgent clinical treatment while gathering evidence.
Frequently Asked Questions
Do I need my records before contacting a solicitor?
No. A short chronology and provider details may be enough for initial triage. Complete records are usually obtained if an investigation proceeds.
Do poor records prove negligence?
Not automatically. They may be relevant, but a claimant still normally proves breach, causation and loss.
Who pays for medical experts?
It depends on the funding agreement. Expert fees and insurance arrangements should be explained before costs are incurred.
What if experts disagree?
Their qualifications, assumptions, reasoning and underlying evidence are examined. A disagreement can affect prospects and may require questions or another discipline.
