California's one-year important date for medical malpractice wrongful death cases
In California, you have one year from the date of death to file a wrongful death lawsuit based on medical malpractice. This is shorter than the important date for other types of personal injury claims in the state, and missing it means you lose the right to sue entirely — there are no exceptions for circumstances you didn't know about or couldn't have discovered sooner.
The one-year clock starts on the date the person died, not the date you discovered the malpractice or realized it caused the death. If a doctor's error on January 15 leads to death on March 20, your important date is March 20 of the following year. If you file on March 21, the case will be dismissed.
This important date applies only to medical malpractice wrongful death claims — cases where a healthcare provider's negligence or error directly caused someone's death. Other wrongful death cases (car accidents, product defects, criminal acts) have different timelines under California law.
Key Takeaways
- You must file a medical malpractice wrongful death lawsuit within one year of the person's death, with no exceptions for delayed discovery.
- The important date is set by California Code of Civil Procedure Section 340.5, which is stricter than the two-year limit for non-fatal medical malpractice injuries.
- Before filing a lawsuit, California law requires you to serve the defendant with a certificate of merit showing a medical informed has reviewed the case.
- If the one-year important date passes, you cannot file the lawsuit, and any claim is permanently barred.
What counts as the "date of death" for the important date
The one-year period begins on the date the person actually died, regardless of when you learned about the malpractice or when you realized it caused the death. This is a strict rule with no flexibility.
If someone dies in a hospital on a specific date, that is the date the clock starts. If a person dies at home and the death is not discovered for several days, the clock still starts on the actual date of death — not the date you found out. Medical records and the death certificate establish the official date.
The law does not pause the important date while you are gathering information, consulting doctors, or deciding whether to pursue a case. Many families do not realize malpractice caused the death until months later, but the one-year limit still applies from the original date of death.
The certificate of merit requirement before you can file
Before you file a medical malpractice wrongful death lawsuit in California, you must serve the defendant with a certificate of merit — a document signed by a medical informed stating that the informed has reviewed the case and believes there is a reasonable basis to believe malpractice occurred. This is a separate requirement from the one-year important date, but it must be completed before or at the time you file.
The informed must be a licensed physician or other may have access to healthcare provider in the same field as the defendant. For example, if a surgeon's error caused the death, the informed must be a surgeon or someone with informed in that surgical specialty. The informed reviews medical records, the treatment provided, and the standard of care to form an opinion.
If you cannot find an informed willing to sign the certificate, you cannot file the lawsuit. This requirement exists to prevent frivolous claims, but it also means you need to identify and consult an informed early — ideally well before the one-year important date approaches. Many attorneys work with medical experts as part of their initial case review.
How the one-year important date differs from other injury claims
Medical malpractice wrongful death has a one-year important date. Non-fatal medical malpractice injuries (where someone is harmed but survives) have a two-year important date under California law. This difference matters because it means wrongful death cases move faster and leave less time to investigate and prepare.
Other types of wrongful death claims — such as those arising from car accidents, defective products, or criminal acts — are governed by different statutes of limitations. A wrongful death claim from a car accident, for example, follows the two-year personal injury timeline, not the one-year medical malpractice timeline. It is critical to identify the correct legal category for your case, because using the wrong important date could cost you the claim.
The one-year medical malpractice important date also has no "discovery rule" exception. In some other injury cases, the clock can start from when you discovered the injury, not when it occurred. Medical malpractice wrongful death does not work that way — the clock starts on the date of death, period.
Who can file the wrongful death claim and what they can recover
In California, only certain family members can file a wrongful death claim: the surviving spouse, domestic partner, children, and parents (if the deceased had no spouse, partner, or children). If none of these relatives exist, the claim may pass to other heirs, but the when ready family has priority.
The damages recovered in a wrongful death case are meant to compensate for the loss of the person's financial support, companionship, and guidance. This includes lost wages the deceased would have earned, medical expenses before death, funeral and burial costs, and the family's pain and suffering from losing the person. Punitive damages (extra damages meant to punish the defendant) are rarely awarded in medical malpractice cases unless the conduct was especially reckless.
The money recovered goes to the estate or is divided among the heirs according to California law. It does not go to the attorney or to the court — the attorney's fee is typically a percentage of what is recovered, agreed to in advance.
What happens if the one-year important date passes
If you miss the one-year important date, the case is dismissed and cannot be refiled. California courts do not grant extensions or exceptions based on hardship, lack of knowledge, or inability to find an attorney. The important date is absolute.
The only narrow exception is if the defendant fraudulently concealed the malpractice — for example, if the doctor deliberately hid evidence or lied about what happened. Even then, the burden of proving fraud is high, and courts rarely grant relief. You would need clear evidence that the defendant actively misled you, not straightforward that you did not discover the malpractice on your own.
If you are approaching the important date and have not yet filed, contact a medical malpractice attorney when ready. Many offer free initial consultations and can quickly assess whether a case exists and what steps need to happen before the important date.
Steps to take before the important date expires
Start by gathering medical records from the hospital, clinic, or provider involved. You can request these directly from the healthcare facility, usually by submitting a written request and paying a copying fee. The records should include all notes, test results, imaging, and communications related to the care.
Next, consult with a medical malpractice attorney. The attorney will review the records and determine whether malpractice likely occurred. If the attorney believes there is a case, they will work with a medical informed to prepare the certificate of merit. This process typically takes several weeks to a few months, depending on the complexity and how quickly the informed can review the file.
Once the certificate of merit is ready, the attorney will draft and file the complaint (the formal lawsuit document) and serve it on the defendant along with the certificate. This must happen before the one-year important date. After filing, the case enters the discovery phase, where both sides exchange information and evidence.
Frequently Asked Questions
Does the one-year important date change if I did not know about the malpractice until later?
No. The important date is based on the date of death, not when you discovered the malpractice. Even if you did not realize a doctor's error caused the death until months later, the one-year clock started on the date of death. This is one of the strictest aspects of California's medical malpractice law.
Can an attorney file the case after the one-year important date if I hire them at the last minute?
Only if the attorney files before the important date expires. The important date is the date the complaint is filed with the court, not the date you sign a contract with an attorney. If you hire an attorney on day 364 of the one-year period, they have one day to file. If they cannot complete the certificate of merit and file in time, the case is lost.
What if the person who died was a minor?
The one-year important date still applies. California does not extend the important date for wrongful death claims involving minors, even though it does extend other important date for minors in different contexts. The family must file within one year of the child's death.
Is the certificate of merit the same as informed testimony at trial?
No. The certificate of merit is a preliminary document required to file the case. It shows that an informed believes malpractice occurred. informed testimony at trial is different — it is the informed's detailed testimony presented in court to prove malpractice to a judge or jury. You will need both.
What if multiple doctors or facilities were involved in the care?
You may be able to name multiple defendants in the same lawsuit. However, you still have only one year from the date of death to file. The certificate of merit requirement applies to each defendant, so you may need multiple experts if different specialties are involved. An attorney can advise on which defendants to include based on the facts.
