When a loved one is seriously injured — or killed — because of someone else’s negligence, the legal process does not stop just because they can’t pursue it themselves. In California, family members and authorized representatives can step in to file on behalf of the injured or deceased. But the rules about who can do that, and how, are very specific.
This guide covers both situations: filing a personal injury claim for a family member who is incapacitated, and filing a wrongful death claim after a fatal accident.
Part 1: Filing a Personal Injury Claim for an Incapacitated Family Member
When Can You File for Someone Else?
If your family member was injured and is physically or mentally unable to manage their own legal affairs — due to a coma, severe cognitive impairment, or other incapacitation — you may be able to file a personal injury claim on their behalf. Before you can do so, you need to establish your legal authority to act.
Legal Guardianship
Legal guardianship is a court-granted relationship that gives one person the authority to make legal and financial decisions for another who cannot do so themselves. If no legal authority is already in place, you will need to file a petition with the court, demonstrate why guardianship is necessary, and potentially appear at a hearing. If the court agrees the injured person cannot manage their own affairs, guardianship is granted.
Two situations can simplify this process:
Automatic guardianship: Parents are typically the automatic legal guardians of their minor children, which means no court petition is required to file a claim on a child’s behalf. Spousal authority may also exist in some circumstances, though this varies by state law.
Power of attorney: If the injured person previously granted you power of attorney covering financial or legal matters, you may already have the authority to act without going through the guardianship process.
What You Need to File
To file a personal injury claim on behalf of a family member, you will generally need:
- Evidence of the injury (medical records, hospital bills, doctor’s reports)
- Documentation proving your legal authority (guardianship papers or power of attorney)
- Proof of the legal criteria being met: the person’s incapacity, your legal relationship to them, and intent to file within the statute of limitations
- Evidence establishing fault and damages
Part 2: Who Can File a Wrongful Death Claim in California?
When a personal injury results in death, the claim transitions from a standard personal injury case to a wrongful death claim. The rules governing who can file are governed by California Code of Civil Procedure 377.60, and the eligibility hierarchy is strictly defined.
Immediate Family: First in Line
The right to file a wrongful death claim starts with the most immediate survivors. Under California law, this means:
- Surviving spouse or domestic partner
- Children of the deceased
If there is no surviving spouse or child, the law extends eligibility further to parents or siblings of the deceased.
Financial Dependents and Stepchildren
Beyond immediate family, California also allows certain others to file if they can demonstrate financial dependence on the deceased. This may include stepchildren or a putative spouse — someone who genuinely believed they were legally married to the deceased. If the loss has created a direct financial hardship, that person may be eligible to file even without a formal family relationship.
The Role of the Personal Representative
In some cases, a single personal representative is appointed to manage the wrongful death claim on behalf of all eligible heirs. This approach simplifies the legal process and ensures that every family member’s interests are represented within a single proceeding rather than multiple competing claims.
What Damages Are Available in a Wrongful Death Case
Wrongful death damages are intended to compensate the surviving family for both financial and emotional losses. They fall into two categories:
Economic damages cover measurable financial losses, including medical costs incurred before death, funeral and burial expenses, and the loss of the deceased’s future income and financial support.
Non-economic damages cover the emotional impact of the loss, including loss of companionship, guidance, and the grief of surviving family members.
In cases involving particularly egregious conduct by the defendant, punitive damages may also be awarded, though this is less common.
How to Move Forward: Key Steps for Either Claim
Whether you are filing a personal injury claim for an injured family member or a wrongful death claim after a loss, the process follows a similar path.
Step 1 — Establish your legal authority. Confirm whether you have automatic guardianship, power of attorney, or whether you need to petition the court. In wrongful death cases, confirm your place in California’s eligibility hierarchy.
Step 2 — Gather evidence. Collect medical records, police reports, witness statements, repair invoices, and any documentation that establishes what happened and who was at fault.
Step 3 — File the claim. Submit the claim to the appropriate court or insurer, with all supporting legal and evidentiary documentation attached.
Step 4 — Navigate pre-trial proceedings. Most cases involve negotiation with the opposing party’s insurance company before any trial. This stage often results in a settlement.
Step 5 — Go to trial if necessary. If a fair settlement cannot be reached, the case proceeds to trial where a judge or jury determines the outcome.
Act quickly. California sets specific statutes of limitations for both personal injury and wrongful death claims. Consulting with an attorney as early as possible protects your ability to file.
