There is no fixed timeline for resolving a traumatic brain injury (TBI) claim in California. Some claims settle through insurance negotiations, while others take considerably longer because of disputed liability, medical uncertainty, or litigation.
The TBI claim timeline in California depends on the circumstances of the accident and the evidence needed to establish the injury’s full consequences. When someone suffers a traumatic brain injury, those consequences may not be immediately apparent.
At Shea & Shea, we help brain injury survivors and their families understand the legal process and pursue compensation that accounts for their losses.

How Long Does a Brain Injury Claim Take?
A brain injury claim may resolve within several months, but complicated cases can take a year or longer. Cases involving extensive litigation may take considerably more time.
The traumatic brain injury settlement process generally involves investigating responsibility, documenting injuries, evaluating damages, and negotiating with the insurer. These activities often overlap, and legal work can begin while medical treatment continues.
A faster settlement is not necessarily better. If future care needs remain uncertain, resolving the claim prematurely could leave significant losses unaccounted for.
Stages of a Traumatic Brain Injury Claim in California
Although every case differs, most TBI claims involve several stages. Understanding these steps can help explain why some cases take longer than others.
1. Immediate Medical Care and Documentation
The first concern after a suspected head injury is obtaining appropriate medical attention. Prompt evaluation can identify serious complications and create records supporting a personal injury claim.
Medical documentation may include:
- Initial evaluations: Emergency records, neurological examinations, and diagnostic testing when appropriate.
- Follow-up appointments: Documentation of persistent or changing symptoms.
- Rehabilitation records: Evidence of treatment progress and ongoing limitations.
Medical recovery and legal investigation can proceed simultaneously. Our San Jose brain injury lawyers can begin reviewing the accident while treatment continues.
2. Investigating the Accident and Establishing Liability
We investigate how the accident occurred and who may be legally responsible. Depending on the circumstances, this may involve:
- Accident reports and photographs
- Surveillance footage and witness statements
- Vehicle maintenance or employment records
- Other evidence establishing responsibility
Some investigations are straightforward. Others involve conflicting accounts or multiple defendants. For example, car accidents involving commercial vehicles may require examining employer responsibility.
The investigation’s duration depends partly on the availability of evidence and the extent to which liability is disputed.
3. Evaluating Recovery and Future Medical Needs
This stage can significantly influence the duration of traumatic brain injury cases.
According to the CDC, the effects of moderate and severe TBI vary between individuals and can change during recovery.
Assessing long-term consequences may involve:
- Future care: Rehabilitation, specialist treatment, and ongoing assistance.
- Employment losses: Lost income and reduced earning capacity.
- Daily limitations: Cognitive difficulties, including memory loss, or reduced independence.
We may consult medical professionals and other qualified specialists to assess future losses. For catastrophic injuries, this evaluation may be extensive.
However, treatment does not always have to conclude before settlement negotiations begin.
4. Preparing and Submitting a Settlement Demand
Once sufficient evidence is available, we can prepare a settlement demand outlining the claim and requested compensation.
A demand package generally addresses:
- Liability: Why another party is legally responsible.
- Medical evidence: Diagnoses, treatment, and anticipated future needs.
- Damages: Financial losses and the injury’s effects on daily life.
Preparing a supported demand may take longer when future medical needs remain uncertain.
Submitting the demand creates an opportunity for negotiations, but it does not guarantee acceptance.
5. Insurance Review and Settlement Negotiations

The insurer reviews the demand and may accept it, make a counteroffer, or request additional information. Disagreements about liability or the appropriate compensation can prolong negotiations.
Insurance policy limits can also influence negotiations. Insufficient coverage may complicate recovery when damages exceed the available insurance.
Our personal injury attorneys evaluate offers against the supporting evidence and our client’s needs. When negotiations do not produce an acceptable resolution, litigation may be appropriate.
6. Filing a California TBI Lawsuit
We may recommend filing a lawsuit when liability remains disputed, settlement offers are inadequate, or a legal deadline approaches.
The initial process generally involves:
- Filing a complaint in the appropriate court.
- Serving defendants with the necessary legal documents.
- Receiving responses to the allegations.
The brain injury lawsuit timeline then depends on court procedures and the disputed issues.
Filing a lawsuit does not necessarily mean going to trial. Settlement negotiations can continue throughout litigation.
7. Discovery and Expert Witness Evaluation
Discovery allows the parties to formally obtain and exchange information relevant to the lawsuit.
It may involve:
- Written discovery: Questions and document requests.
- Depositions: Sworn testimony from parties or witnesses.
- Professional evaluations: Medical assessments and expert testimony about the injury’s consequences.
Expert witnesses may help explain long-term impairment, future treatment needs, or lost earning capacity.
The brain injury lawsuit timeline may lengthen when evidence is difficult to obtain or the parties dispute discovery requests.
8. Mediation, Settlement, and Trial Preparation
Mediation allows the parties to explore settlement with assistance from a neutral third party.
If mediation is unsuccessful, we continue preparing for a possible trial. This may involve arranging witness testimony, reviewing evidence, and meeting court deadlines.
Settlement remains possible as trial approaches. If the case proceeds to trial, its duration will depend partly on the court’s schedule.
What Factors Can Shorten or Lengthen a TBI Claim?
Several circumstances can affect the TBI claim timeline in California:
- Medical recovery: Changing symptoms or uncertain treatment needs can complicate damages assessments.
- Liability disputes: Conflicting evidence or multiple defendants may require further investigation.
- Future-care projections: Serious injuries may require assessments of long-term rehabilitation and assistance.
- Insurance coverage: Policy limits or coverage disputes can affect negotiations.
- Government involvement: Public-entity claims have special procedures and deadlines.
- Court schedules: Discovery disputes, expert availability, and trial calendars can extend litigation.
These factors affect cases differently. A mild traumatic brain injury, such as a concussion, may involve persistent symptoms and disputed medical evidence, while a severe injury with clear liability may still require extensive evaluation of future care needs.
Our focus is pursuing compensation supported by the evidence, not simply obtaining the fastest possible settlement.
How Long Do You Have to File a Brain Injury Claim in California?
The deadline for starting a lawsuit is different from the time required to resolve it.
California’s General Two-Year Personal Injury Deadline
Under California Code of Civil Procedure § 335.1, injured individuals generally have two years from the date of injury to file a personal injury lawsuit.
This deadline concerns initiating legal action, not completing the case.
Exceptions and special rules may apply, including certain circumstances involving minors or delayed discovery of an injury. Importantly, medical treatment and settlement negotiations do not automatically suspend the filing deadline.
Shorter Deadlines for Government Claims
Under California Government Code § 911.2, personal injury claims against public entities generally must be presented within six months of the injury.
Government agencies generally have 45 days to act on a claim. If an agency issues a qualifying written rejection, the injured person generally has six months from the notice’s delivery or mailing to file a lawsuit. If no qualifying written rejection notice is provided, the injured person generally has two years from the injury date to file a lawsuit, but the initial government claim must still be presented on time.
Because exceptions and other requirements may apply, we recommend obtaining case-specific legal advice promptly.
What Happens After a Brain Injury Settlement Is Reached?
Reaching an agreement does not necessarily mean settlement funds become immediately available.
The final stage of the traumatic brain injury settlement process may involve:
- Completing settlement documents and releases
- Receiving and processing payment
- Addressing medical reimbursement obligations or liens
- Distributing funds after applicable deductions
The timing depends on the settlement terms and outstanding obligations. We can explain what remains before payment can be distributed.
FAQs
How long does a brain injury claim take when liability is disputed?
Disputed liability can extend the process because additional investigation may be required. We may need further evidence to establish responsibility. If negotiations cannot resolve the disagreement, litigation may be necessary.
Can a TBI claim settle before medical treatment is finished?
Yes. Ongoing treatment does not necessarily prevent settlement. However, future medical expenses and lasting limitations should be reasonably evaluated before accepting an agreement that generally ends the right to seek additional compensation.
Does a mild traumatic brain injury claim usually settle faster?
Not necessarily. Even mild TBI cases can involve persistent symptoms or disagreements about causation. The available medical evidence and the insurer’s position may have greater influence on timing than the initial injury classification.
Does filing a California TBI lawsuit mean my case will go to trial?
No. Lawsuits can settle through negotiations or mediation before trial. We continue considering appropriate settlement opportunities while preparing the case for court when necessary.
What happens if the insurance company delays my claim?
Our personal injury lawyers can request updates, address outstanding information requests, and evaluate available legal options. We also monitor filing deadlines so prolonged negotiations do not jeopardize our client’s legal rights.
Can I file a lawsuit while settlement negotiations continue?
Yes. Filing a lawsuit generally does not prevent continued negotiations. Legal action may be necessary to preserve a claim before the applicable deadline, even when both parties remain interested in settlement.
How long does it take to receive money after a TBI settlement?
There is no universal payment timeline. The settlement terms, payment processing, and outstanding reimbursement obligations can affect when funds become available.
