A persuasive description can be fragile when the underlying sources are incomplete or inconsistent. A reliable claim is built so another person can trace each material fact, test alternatives, and understand what remains unknown.

Case reliability comes from traceable sources, disclosed uncertainty, and proof that survives contrary testing.

Use a source ledger

  • Material fact or issue
  • Original source, custodian, date, and location
  • Authentication and completeness status
  • Contrary source, uncertainty, follow-up action, owner, and deadline

Preserve originals and context

Keep original photographs, video, messages, exports, data, reports, objects, packaging, receipts, and document versions. Preserve metadata and chain of custody. Do not crop, filter, annotate, repair, test, or discard an item without documenting the original and authority.

Use independent evidence when available

Camera footage, electronic data, measurements, inspection records, contemporaneous reports, admissions, and disinterested witnesses can test participant accounts. Independence does not make a source infallible; accuracy and completeness still require review.

Build a complete medical chronology

  • Baseline, event mechanism, symptom onset, examinations, diagnoses, tests, treatment, and response
  • Prior similar history, gaps, later events, alternative causes, and inconsistencies
  • Restrictions, function, prognosis, and future recommendations
  • Complete records and images rather than selected portal pages

Reconcile medical expense

Rule 414 limits past-medical-expense evidence to paid amounts for satisfied bills and amounts actually necessary for incurred but unpaid bills. The ledger should connect each treatment record to its itemized charge, payment, adjustment, and balance.

Test alternative causation

Identify alternative event mechanisms, prior conditions, later incidents, natural progression, unrelated disease, inconsistent timing, and other explanations. Then state the evidence that supports or weakens each one.

Use qualified opinion with transparent inputs

Rule 702 requires sufficient facts or data, reliable methods, and reliable application. Record every material assumption, source supplied, alternative considered, and limit of the opinion.

Prepare for discovery

Rule 26 describes depositions, interrogatories, electronically stored information and document requests, examinations, admissions, and expert discovery. Organize records so answers can be complete, consistent, and updated without reconstructing the file from memory.

Document function and income from source records

Use medical restrictions, job duties, employer records, wages, schedules, leave, tax or business records, and task-specific function. Corroboration should add detail rather than repeat a conclusion.

Preserve defense evidence

Include warnings, visibility, instructions, client conduct, prior statements, releases, coverage letters, limitation facts, and other material defense sources. Omitting unfavorable material makes the evaluation less reliable.

Use version control and a change log

For chronologies, calculations, exhibits, pleadings, discovery, reports, and settlement summaries, record author, date, source inputs, changes, and approval. Avoid multiple unlabeled “final” versions.

State uncertainty directly

Use known, disputed, inferred, and unknown labels. Explain what evidence would resolve the issue and how the assessment changes under each plausible result. Reliability includes the boundaries of current knowledge.
