TBI After a Crash, Fall, or Assault: How the Claim Path Differs

A brain injury arising from a crash on the 101, a fall in a Los Angeles neighborhood, an assault, or medical care may involve different parties and procedural rules. This guide is for injured people and families identifying the right California claim path. It compares how the underlying event affects deadlines, parties, and proof, while emphasizing preservation before the cause or long-term effects are fully known.

Start with the event that caused the TBI

California’s verified facts identify no separate limitations period for traumatic brain injury. The applicable rule depends on the cause: crash, fall, assault, medical negligence, or conduct involving a public entity may raise distinct timing questions.

Write down event date, location, what happened, and each person or entity involved. Separate that event chronology from the medical timeline. Incident date, first symptoms, diagnosis, and discovery of possible medical error are different facts that may matter under different rules.

Do not assume injury severity selects the deadline. TBI is a medical description, not a standalone legal claim category in the verified materials. The cause and responsible parties determine which law should be checked.

If the cause is uncertain, preserve possible paths while collecting records. Avoid choosing a single theory based only on the first explanation offered, particularly if more than one event or provider may have contributed.

Crash, fall, or other injury-event claims

Many personal-injury actions for injury caused by another’s wrongful act or neglect generally must be filed within two years under CCP § 335.1. That rule may be relevant after a crash, fall, or assault, depending on the facts and parties.

A later diagnosis does not automatically create a separate TBI deadline in the verified facts. Preserve the event date and later symptom, treatment, and diagnosis dates. Have the applicable rule assessed rather than assuming the clock starts when a final label appears.

California pure comparative negligence under *Li v. Yellow Cab Co.* (1975) 13 Cal.3d 804 means partial fault reduces damages proportionally but does not fully bar recovery. Fault may be contested, so preserve evidence about the event and each person’s actions.

If several parties contributed, Civil Code § 1431.2 makes economic damages joint while non-economic damages are several by fault. Early party identification helps keep evidence and allocation issues organized.

Medical negligence follows a different timing framework

If alleged medical negligence caused the brain injury, the malpractice deadline generally applies. CCP § 340.5 sets the earlier of three years from injury or one year from discovery, including when reasonable diligence should have revealed the injury.

The outer limit has narrow tolling exceptions for proof of fraud, intentional concealment, or a retained foreign body with no therapeutic or diagnostic purpose. A delayed diagnosis or evolving symptoms do not by themselves establish an exception; the one-year discovery period remains relevant.

A 90-day advance notice of intent to sue generally is required under CCP § 364. If served within the final 90 days of limitations, the verified rule extends the deadline 90 days from service. Track this separately from the one-year and three-year dates.

Minor patients have a special verified rule: generally three years from the wrongful act; a child under six has until the eighth birthday if that is longer. Do not apply that malpractice rule to every TBI claim without identifying medical negligence as the cause.

Public entities can add a claim-presentation step

A written public-entity claim generally must be presented within six months of injury or death under Government Code § 911.2. Verified examples include cities, counties, Metro/LA Metro, LAUSD, Caltrans, and the State of California.

If rejected in writing, suit generally must be filed within six months of notice under § 945.6(a)(1). If no written rejection was sent, the general two-year limit applies under § 945.6(a)(2). A late-claim application may be made within a reasonable time, not more than one year, under § 911.4.

This is a claim-presentation process, not simply an ordinary lawsuit deadline. Identify the actual agency and preserve reports and correspondence. Do not use a building or route name alone to determine which entity is legally responsible.

A public-entity issue may overlap the underlying injury category. If medical care and a public operator are both involved, or a public vehicle and another driver, seek review of all possible deadlines rather than applying one.

The claim path also shapes what evidence to preserve

After a crash or fall, preserve information about how the event happened, who was involved, and what was observed. For possible medical negligence, preserve the treatment chronology and provider communications. If a public entity is involved, keep the agency identity and claim correspondence.

Separate medical conclusions from event facts. Incident records help establish cause and responsibility, while medical records document the condition and care. A symptom note alone does not resolve who caused the symptoms.

For future expenses, CACI 3903A requires reasonably necessary care to be proven to a reasonable certainty, generally with competent testimony from a practitioner qualified in the relevant field. A qualified practitioner’s life care plan grounded in treating-provider recommendations is a standard way to support future TBI costs.

Keep unfavorable as well as favorable information. A balanced record lets the case be evaluated fairly and helps address disputes over causation, fault, or future-care necessity.

Practical next steps while the cause is assessed

Create a concise event summary and a separate chronology of symptoms and care. Identify potential responsible parties, including a provider or public entity only where the facts support considering them. Mark uncertainties rather than filling them in.

Use separate deadline lines for possible paths: two years under § 335.1, malpractice under § 340.5 with notice under § 364, and public-entity claim rules under §§ 911.2 and 945.6 where applicable. Do not assume one clock replaces another.

Use this first-step checklist:

• Write down event date, location, and known circumstances.
• Separate incident, symptom, diagnosis, and discovery dates.
• List possible parties and identify any provider or public entity.
• Preserve incident and medical records in original form.
• Ask promptly which deadline applies; do not wait for a final prognosis.
• Organize future-care recommendations for review under CACI 3903A.

When more than one cause may be involved

Sometimes available facts do not point to one cause immediately. A crash may be followed by treatment, a fall may occur after a medical event, or several parties may act at different stages. Preserve each event and its date rather than collapsing the history.

For each possible cause, identify parties and timing rules. Many injury claims generally use § 335.1; malpractice generally uses § 340.5 and § 364 notice; public-entity claims generally begin with six-month presentation under § 911.2. Do not assume one route covers another.

Keep proof of each stage in original form. Incident photographs or reports relate to what occurred; provider records concern treatment; communications can show when new information became known. Label source and date so stages remain distinct.

If a public entity appears in the sequence, preserve its legal name and claim correspondence. A written rejection can trigger a separate six-month lawsuit period under § 945.6(a)(1). Record the response date and content accurately.

Where malpractice may be part of the explanation, note when injury was first recognized and what prompted concern. The one-year discovery period in § 340.5 differs from general injury timing. Do not assume diagnosis date sets every clock.

The same injury may require separate review of liability, comparative fault, and damages. Under § 1431.2, economic damages are joint while non-economic damages are several by fault. That allocation rule does not decide who caused the brain injury.

For future care, retain recommendations and support for a life care plan under CACI 3903A. That evidence question is distinct from identifying the responsible party. An orderly file lets reviewers assess cause and care needs separately.

An event map can help show whether the case involves one occurrence or a chain of events. Put each event on a separate line with date, location, parties, and supporting source. This makes it easier to distinguish the cause of the brain injury from later treatment and from losses that continue afterward.

If the responsible party is disputed, preserve information for each possibility without presenting an assumption as settled fact. A public entity, private party, or provider may raise distinct rules. The record should show why each is being considered and what information is still needed to confirm or rule it out.

Keep deadline review active as evidence develops. A later medical record may clarify causation, but it does not automatically replace the calendar already based on a possible injury or public-entity claim. Update the analysis with counsel when facts change, and retain the documents showing why the updated date was selected.

Los Angeles County context

For a traumatic brain injury claim arising in Los Angeles County, the courthouse and deadline depend on the event and defendant. Most personal injury matters are filed in Los Angeles County Superior Court and Los Angeles County Superior Court; the exact courthouse assignment should be confirmed for each case before filing. Keep incident location, date, parties, and treating-provider details together so the correct claim path can be assessed.
