TBI Claim Deadlines in California Depend on the Injury’s Cause

A head injury after a collision on a Los Angeles freeway, a neighborhood fall, or alleged medical negligence can raise different deadline questions. This guide is for people with a suspected TBI and families helping protect a claim. California has no TBI-specific filing clock; the cause determines which general rule to evaluate, so this guide compares those paths and first steps.

There is no single California TBI deadline

The verified California facts identify no TBI-specific statute of limitations. The deadline depends on how the injury occurred. A TBI after a crash or fall may follow the general injury rule; an injury allegedly caused by medical negligence follows the malpractice rule.

The periods are not interchangeable. Many personal-injury actions generally must be filed within two years of injury under CCP § 335.1. Medical-malpractice claims generally use the earlier of three years from injury or one year from discovery under § 340.5.

A public entity may add claim presentation. A written claim generally must be presented within six months under Government Code § 911.2. That process differs from filing a lawsuit and should be considered when an agency may be involved.

Do not calculate from the label “TBI” alone. Identify the event, date, potential responsible parties, and whether a special category may apply. Keep each potential deadline separately until the proper path is confirmed.

If the TBI followed a crash, fall, or other injury event

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

A medical diagnosis may come after the event, but the verified facts do not create a general TBI-specific discovery extension. Record the incident date and later symptom, evaluation, and diagnosis dates; do not assume that a later diagnosis automatically restarts the period.

If more than one person or entity may have contributed, identify them separately. Civil Code § 1431.2 makes economic damages joint while non-economic damages are apportioned severally by fault.

Keep scene information, witness details, and records together, even if the precise cause is still under investigation. A clear timeline separates the incident date from later treatment milestones.

If medical negligence caused the TBI

When medical negligence is the alleged cause, the malpractice rule generally applies. Under CCP § 340.5, filing is due by the earlier of three years from injury or one year from discovery, including when reasonable diligence should have revealed the injury.

Tolling of the three-year limit is narrow: proof of fraud, intentional concealment, or a retained foreign body with no therapeutic or diagnostic purpose. Do not assume that complex symptoms or later diagnosis establish an exception. The one-year discovery period remains relevant.

Minor patients have a special rule: generally three years from the wrongful act, while a child under six has until the eighth birthday if longer. Record age and dates of the alleged medical act accurately.

A 90-day notice of intent to sue generally is required before filing under CCP § 364. If notice is served within the final 90 days of limitations, the verified rule extends the deadline 90 days from service. Track notice and filing dates independently.

If a public entity may be responsible

A written public-entity claim generally must be presented within six months of injury or death under Government Code § 911.2. The verified examples include city, county, Metro/LA Metro, LAUSD, Caltrans, and the State of California. A public bus, place, or employee may warrant checking agency involvement.

If the claim is 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.

These rules do not identify the cause of injury. A TBI allegedly caused by medical negligence at a public facility may require review of more than one deadline. Confirm the legal identity and public status of the operator rather than inferring it from the building name.

Preserve location, photographs, report information, and involved agency names. Do not wait to resolve every medical issue before checking whether the public-entity clock may be running.

How diagnosis timing and age affect the calendar

A delayed or evolving diagnosis complicates the facts but does not by itself establish that a deadline is delayed. For ordinary personal injury, the supplied rule generally is two years from injury under § 335.1. For malpractice, the one-year discovery rule is expressly part of § 340.5.

Keep distinct entries for incident, first symptoms, first evaluation, later diagnosis, and when you first questioned a connection to the event or care. That record can help assess which date matters without assuming one milestone controls every claim.

For a child whose TBI may have resulted from medical negligence, consider the special minor rule. The verified facts describe three years from the wrongful act generally and an under-six rule through the eighth birthday if longer. Do not apply that malpractice rule to every TBI claim.

If the injured person cannot manage records or dates, ask a trusted family member to maintain copies and chronology. Do not delay a deadline inquiry while waiting for a long-term prognosis; diagnosis and legal timing are different questions.

What to do immediately to protect the right path

Write down the event date and how the injury occurred. Identify all potentially involved people and entities, including a possible public body or health care provider. If cause remains uncertain, mark it as uncertain and preserve records for each plausible path.

Collect available medical records and timeline, but do not wait for the complete chart before asking about deadlines. A two-year injury period, malpractice rule, and public-entity claim window can differ substantially. Prompt review can help identify what should happen first.

Use this checklist:

• Record event date, location, and basic circumstances.
• List possible defendants and whether any may be a public entity or provider.
• Keep incident, symptom, diagnosis, and discovery dates distinct.
• Calendar possible rules: CCP § 335.1, CCP § 340.5, and Gov. Code § 911.2.
• If malpractice is possible, separately track CCP § 364 notice.
• Preserve records; do not wait for a final prognosis to ask about deadlines.

Choosing the correct clock is the first task

Write facts before choosing a legal category. A short incident description should include what happened, where, the date, and who was involved. List later symptoms and care separately. This distinguishes the event potentially creating liability from the diagnosis explaining its effects.

For a general injury claim, the verified rule generally is two years under CCP § 335.1. If medical negligence is alleged, § 340.5 uses the earlier of three years from injury or one year from discovery. Public entities may require a written claim within six months under Government Code § 911.2. These alternatives make early classification important.

When facts suggest more than one path, do not select only the longest deadline. A collision might involve a private driver and public vehicle; a fall might involve public property; later care may raise malpractice. Identify each possibility and have it checked.

Keep any public-agency response, including rejection, with incident records. A written rejection generally starts six months under § 945.6(a)(1), while no written rejection is treated differently under § 945.6(a)(2). Record the status and date exactly.

For possible malpractice, preserve when injury was recognized and what prompted inquiry. Discovery under § 340.5 may depend on what was known or reasonably should have been learned; diagnosis date alone may not resolve it.

If the injured person is a child, record age and birth date before applying any special rule. The verified under-six provision concerns malpractice and provides until the eighth birthday if longer. Do not transfer it automatically to another TBI claim.

Bring the timeline, party list, and records for prompt review. The aim is to identify all potentially applicable rules before a period expires, not to predict which claim succeeds.

Keep a separate worksheet for each possible route rather than one master date labeled “deadline.” Include the authority, triggering event, date used, and any uncertainty. If later information changes the potential cause or defendant, update the worksheet and retain the prior calculation so the reason for the change remains visible.

For a public entity, preserve the claim form or written presentation and any correspondence about acceptance or rejection. The date of a written rejection may be important under Government Code § 945.6(a)(1). If no written rejection appears, note that fact and have the applicable rule checked rather than assuming a response was sent.

For a possible malpractice route, separately identify any notice served under § 364 and the date of service. Do not combine the public-entity claim date, notice interval, and underlying statute into one calculation. They are different procedural steps, and each needs its own supporting evidence.

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 the incident location, date, involved parties, and treating-provider details together so the correct claim path can be assessed.
