Why Choose Commonwealth Legal Group for Wrongful Death Cases in Diamond Bar, CA?
A Lawyer Who Fights for Families, Not Just Settlements
Wrongful death cases carry weight that other personal injury claims don’t. The stakes are different. The emotional toll on the family is immense. And the pressure from insurance companies to settle quickly and cheaply is relentless. Attorney Albert Ng understands that a wrongful death case is about more than a number. It’s about a family that lost someone irreplaceable and a system that needs to hold the responsible party accountable. That’s why he prepares every case for trial, not just negotiation.
Albert’s $2.2 million trial verdict in a rear-end collision case, where the defense offered $0 in settlement, demonstrates what happens when an insurance company refuses to act in good faith. He took the case to a jury and won. That verdict earned a Top 50 Verdict in 2020 and was reported by the Daily Journal. In wrongful death cases, where the losses are catastrophic and permanent, that willingness to go to trial is not optional. It’s essential.
Millions of Dollars Recovered for Injured Clients and Their Families
Across all personal injury case types, Albert has recovered millions of dollars for his clients.. That includes results in car accident cases, truck accident claims, pedestrian injuries, and slip and fall cases. When negligence takes a life, the damages are the highest of any personal injury case, and the attorney handling the claim needs a proven record of recovering substantial compensation.
A California Trial Lawyer Since 2016
Albert earned his J.D. from Thomas Jefferson School of Law in San Diego and his bachelor’s degree from Boston University in 2010. He was admitted to the California Bar in December 2016 and is a member of the Consumer Attorneys Association of Los Angeles. If you need a personal injury lawyer in Diamond Bar, CA who handles wrongful death claims, Albert has the litigation background and the sensitivity to guide your family through this process.

Types of Wrongful Death Cases We Handle in Diamond Bar

- Fatal car accidents. Speeding, distracted driving, drunk driving, and running red lights kill hundreds of people in Los Angeles County every year. When a driver’s negligence causes a death, the surviving family can pursue a wrongful death claim against the at-fault driver and their insurance.
- Fatal truck accidents. Commercial truck crashes produce a disproportionate number of fatalities because of the massive weight difference between trucks and passenger vehicles. These cases often involve the truck driver, the trucking company, and their respective insurers.
- Pedestrian fatalities. Over 1,100 pedestrians were killed on California roads in 2023. Diamond Bar’s busy corridors, including Diamond Bar Boulevard and the streets near the SR-57/SR-60 interchange, see regular pedestrian traffic in close proximity to fast-moving vehicles.
- Motorcycle and bicycle fatalities. Riders have almost no protection in a collision. Fatal motorcycle and bicycle crashes often involve drivers who failed to see the rider or violated their right of way.
- Fatal premises liability incidents. A fall from a defective staircase, an electrocution caused by faulty wiring, a drowning in an unguarded pool. When a property owner’s failure to maintain safe conditions results in death, the family has a wrongful death claim.
- Fatal rideshare accidents. Deaths involving Uber or Lyft vehicles raise complex insurance questions. Our firm recovered $600,000 in a rideshare accident case. Fatal rideshare cases involve even higher stakes and additional insurance coverage.
- Deaths caused by defective products. When a faulty vehicle part, a dangerous household product, or a defective medical device causes a death, product liability law may apply alongside wrongful death claims.
California Legal Requirements for Wrongful Death Cases

Under CCP Section 377.60, a wrongful death lawsuit can be filed by the decedent’s surviving spouse or domestic partner, children, or grandchildren (if the decedent’s children are also deceased). If none of those individuals exist, the right to file extends to anyone who would be entitled to the decedent’s property under California’s intestacy laws, or anyone who was financially dependent on the decedent. The decedent’s personal representative can also file on behalf of these individuals.
Under CCP Section 377.61, damages in a wrongful death case may include whatever the court considers just under all the circumstances. This includes the financial support the family lost, funeral and burial costs, the value of household services the decedent provided, and the loss of love, companionship, comfort, care, affection, and moral support.
The statute of limitations for a wrongful death claim is two years from the date of death under CCP Section 335.1. If the death was caused by a government entity, such as a city vehicle or a dangerous road condition maintained by a public agency, the deadline to file an administrative claim may be as short as six months under Government Code 911.2. These deadlines are absolute, and missing them can permanently bar your family’s claim.
California’s comparative fault rules apply to wrongful death cases. If the decedent shared some responsibility for the incident that caused their death, the family’s damages are reduced by the decedent’s percentage of fault, but not eliminated.
What Damages Are Recoverable in a Diamond Bar Wrongful Death Case?

Economic damages cover the financial impact of the death. This includes the income and financial support the decedent would have provided to the family over their expected lifetime, the value of benefits like health insurance and retirement contributions, funeral and burial expenses, the cost of household services the decedent performed, and the reasonable value of care the decedent provided to dependents, including children and elderly parents. These calculations often require economic analysis to project lost future earnings, which is why having an attorney who works with forensic economists matters.
Non-economic damages compensate for the personal losses that don’t carry a price tag but are devastatingly real. Loss of love, companionship, comfort, care, affection, society, and moral support. Loss of guidance and training for the decedent’s children. Loss of the enjoyment of sexual relations for a surviving spouse. These losses are subjective, but California courts have long recognized their significance and awarded substantial compensation for them. The loss of a parent, a spouse, or a child reshapes every aspect of a family’s daily life, and the law accounts for that.
Survival action damages may also be available. A survival action, filed through the decedent’s estate under CCP Section 377.30, allows recovery for damages the decedent themselves would have been entitled to, including medical expenses incurred between the injury and death, lost wages during that period, and pain and suffering experienced before death. A wrongful death claim and a survival action are often filed together to maximize the total recovery for the family.
What Steps Should I Take After a Wrongful Death in Diamond Bar?

- Obtain a copy of the death certificate. You’ll need this for the wrongful death claim, the survival action, and for insurance purposes.
- Request the police report or incident report. If the death resulted from a traffic accident, workplace incident, or other reportable event, get the official report. This is critical evidence.
- Preserve all evidence. Do not discard any personal property, medical records, photographs, correspondence, or documentation related to the incident. If the death involved a vehicle, do not authorize repairs or disposal of the vehicle until an attorney has assessed the case.
- Do not speak with the at-fault party’s insurance company. Insurers will contact the family quickly after a fatal accident. They will express sympathy. They will also look for ways to limit what they pay. Do not give any recorded statements. Direct all communication to your attorney.
- Identify all potentially responsible parties. In some wrongful death cases, multiple parties share fault. A fatal truck accident may involve the driver, the trucking company, and a maintenance provider. A fatal premises incident may involve the property owner and a contractor. An attorney can investigate and identify all liable parties.
- Determine who has standing to file. California law limits who can bring a wrongful death claim. Typically, the surviving spouse, domestic partner, children, or grandchildren have priority. If none exist, other dependents or heirs may qualify. An attorney can confirm whether you have standing.
- Be aware of deadlines. The two-year statute of limitations starts running from the date of death, not the date of the accident (if they differ). Government entity claims have even shorter deadlines. Missing these deadlines is permanently disqualifying.
- Keep records of all financial impacts. Document the decedent’s income, benefits, household contributions, and any expenses the family has incurred as a result of the death, including funeral costs and counseling.
- Take care of yourself and your family. Grief counseling, support groups, and leaning on trusted people in your life are not signs of weakness. They are necessary. Your wellbeing matters, and addressing it now is part of the recovery process.
- Contact a wrongful death attorney as soon as you’re able. Evidence degrades quickly after a fatal incident. Surveillance footage gets overwritten. Witnesses become harder to locate. Vehicle data may be lost. The sooner an attorney can begin preserving evidence and investigating, the stronger your case will be. Learn more about when to hire an attorney and the typical case timeline.
Wrongful Death Statistics in Diamond Bar

In California, the Office of Traffic Safety reported 4,061 traffic fatalities statewide in 2023. Los Angeles County alone averaged nearly 788 traffic-related deaths per year over the past five years. In the city of Los Angeles, traffic deaths have exceeded homicides for two consecutive years, with 302 traffic fatalities recorded in 2024. Of those, 170 were pedestrians.

For Diamond Bar families, the risk of losing a loved one to a preventable accident is very real.

Diamond Bar Wrongful Death Lawyer FAQs
Who can file a wrongful death lawsuit in California?
Under CCP Section 377.60, the surviving spouse or domestic partner, children, and grandchildren (if the children are deceased) have first priority. If none of these individuals exist, anyone entitled to the decedent’s property under intestacy law, or anyone who was financially dependent on the decedent, may file. The decedent’s personal representative can also file on behalf of eligible parties.
How long do I have to file a wrongful death claim?
Two years from the date of death. If a government entity is potentially responsible, you may have only six months to file an administrative claim. These deadlines are firm and missing them can permanently eliminate your right to seek compensation.
What is the difference between a wrongful death claim and a survival action?
A wrongful death claim compensates the surviving family for their losses, including lost financial support, loss of companionship, and funeral costs. A survival action compensates the decedent’s estate for damages the decedent suffered before death, such as medical expenses and pain and suffering between the injury and death. Both are typically filed together.
Can I file a wrongful death claim if the at-fault person is facing criminal charges?
Yes. A wrongful death case is a civil action, separate from any criminal prosecution. The two can proceed simultaneously. The burden of proof in civil court is lower than in criminal court, which means a civil case can succeed even if the criminal case results in an acquittal.
How much is a wrongful death case worth?
It depends on many factors: the decedent’s age, income, earning potential, the number of dependents, the nature of the relationship between the decedent and the claimants, and the circumstances of the death. The average California wrongful death settlement is approximately $973,000 according to recent data, but many cases exceed $1 million significantly.
What damages can I recover in a wrongful death case?
Financial support the decedent would have provided, funeral and burial costs, the value of household services, loss of companionship and affection, loss of guidance and moral support, and through a survival action, medical expenses and pain and suffering the decedent experienced before death.
Does a wrongful death case go to trial?
Most settle before trial, but some require litigation. Attorney Ng’s $2.2 million verdict after a $0 offer demonstrates that going to trial can be the right choice when the insurer refuses to make a fair offer. We prepare every wrongful death case for trial.
Can I recover punitive damages in a wrongful death case?
California does not allow punitive damages in wrongful death claims. However, punitive damages may be recoverable through a companion survival action if the defendant’s conduct amounted to malice, oppression, or fraud.
What if my loved one was partially at fault?
California’s comparative fault rules still apply. The family’s recovery is reduced by the decedent’s percentage of fault but is not eliminated entirely.
Who pays for a wrongful death attorney?
We work on contingency. You pay no fees unless we recover compensation for your family. The fee is a percentage of the recovery. There are no upfront costs and no hourly billing.
What if the person who caused the death has no insurance?
Your attorney will investigate all possible sources of recovery, including the at-fault party’s personal assets, employer liability, and any other applicable insurance policies. In some vehicle accident cases, the decedent’s own uninsured/underinsured motorist coverage may also apply.
How long does a wrongful death case take?
It varies. Simpler cases with clear liability may resolve within several months. Complex cases involving multiple defendants, disputed fault, or extensive damages calculations can take a year or longer. If the case goes to trial, additional time is needed.
Can I file a wrongful death claim for a child?
Yes. Parents can file a wrongful death claim for the loss of a minor child. The damages focus heavily on loss of companionship, comfort, and the parent-child relationship, as the child may not have had significant income at the time of death.
Should I accept the insurance company’s offer?
Not without consulting a wrongful death attorney. Initial offers in fatal cases are almost always below the true value of the claim. Insurance companies count on grieving families accepting quick settlements before they understand the full scope of their losses.
What if the death happened at work?
Workplace fatalities may involve both a workers’ compensation death benefit claim and a wrongful death lawsuit if a third party’s negligence caused the death. For example, if a defective piece of equipment caused the fatality, the manufacturer could be liable in a civil action separate from the workers’ compensation claim.
Dangerous Locations for Wrongful Deaths in Diamond Bar

The SR-57/SR-60 Interchange is the most dangerous location in Diamond Bar for fatal collisions. Ranked the worst truck bottleneck in California and ninth worst nationally, this interchange funnels massive volumes of passenger vehicles and freight traffic into a complex merging zone where lane-weaving, speed differentials, and limited reaction time produce high-speed crashes. Fatal collisions involving semi trucks and passenger vehicles are documented repeatedly in this corridor. The weight disparity between a fully loaded commercial truck and a standard car makes any collision at freeway speed potentially fatal. The ongoing $444 million improvement project introduces additional hazards, including lane shifts, narrowed shoulders, and construction equipment, that will persist through 2028.
SR-57 (Orange Freeway) through Diamond Bar carries commuter and commercial traffic between Orange County and the San Gabriel Valley. High-speed rear-end collisions, lane-change crashes, and chain-reaction pileups on this freeway have resulted in fatalities involving Diamond Bar residents. On-ramp and off-ramp areas near Diamond Bar Boulevard and Pathfinder Road are particularly dangerous zones where vehicles accelerating to freeway speed or decelerating to exit create sudden speed differentials.
SR-60 (Pomona Freeway) along Diamond Bar’s southern border is a major east-west freight corridor connecting the ports of Los Angeles and Long Beach to the Inland Empire. The volume of truck traffic on this stretch makes fatal truck-versus-passenger-vehicle crashes a persistent threat. Fatigue-related incidents involving commercial drivers traveling long distances on this route contribute to the danger, especially during overnight and early morning hours.
Diamond Bar Boulevard is the city’s central artery and the location of numerous fatal and serious-injury collisions. The combination of high traffic volume, multiple signalized intersections, commercial driveways, and pedestrian crossings creates conditions where fatal T-bone crashes, pedestrian strikes, and left-turn collisions occur. Pedestrians crossing near shopping centers and bus stops along
Diamond Bar Boulevard are at heightened risk, particularly during evening hours when driver visibility is reduced.
Golden Springs Drive connects residential neighborhoods to schools, commercial areas, and freeway access points. Fatal accidents along this corridor have involved pedestrians near school zones, cyclists sharing the road with fast-moving traffic, and intersection collisions at major crossings including
Diamond Bar Boulevard and Brea Canyon Road. The heavy school-related traffic during morning and afternoon hours places children and parents at elevated risk.
Grand Avenue carries commuter traffic between Diamond Bar and Walnut and transitions between residential and commercial speed zones. Fatal collisions on Grand Avenue often involve speed differentials where drivers accelerate out of slower commercial areas into faster-moving stretches. Pedestrian fatalities near retail centers along this road have occurred during evening hours when lighting is insufficient and driver attention is divided.
Brea Canyon Road runs north-south through Diamond Bar and provides direct access to SR-60 freeway on-ramps. The road passes through residential and commercial zones, and its intersections with Golden Springs Drive and Pathfinder Road have been the sites of serious and fatal collisions. Cyclists using Brea Canyon Road are particularly vulnerable to fatal crashes with vehicles turning into and out of commercial driveways without checking for bike traffic.
Pathfinder Road winds through the southern hillside portions of Diamond Bar, with curves, elevation changes, and limited sightlines that contribute to fatal head-on and single-vehicle crashes. Speeding on the winding sections near hillside residential developments is a recurring factor. Pedestrians walking along stretches without sidewalks to reach nearby trailheads face the risk of being struck by vehicles that cannot see them around curves.
Commercial parking lots and adjacent roadways throughout Diamond Bar, including the areas around Diamond Hills Plaza, Country Hills Towne Center, and Gateway Center, are locations where pedestrian fatalities occur. Drivers backing out of spaces, making turns without checking for foot traffic, and accelerating through lot exits into pedestrian paths contribute to these deaths. Elderly pedestrians are disproportionately represented in fatal parking lot incidents.
Intersections throughout Diamond Bar account for a significant share of fatal crashes in the city. The intersections of Diamond Bar Boulevard and Golden Springs Drive, Diamond Bar Boulevard and Grand Avenue, and Brea Canyon Road and Pathfinder Road see high volumes of cross-traffic where failure to yield, red-light running, and distracted driving produce fatal T-bone collisions. Left-turn fatalities at signalized intersections are among the most common types of deadly crashes in suburban communities like Diamond Bar.
No location can undo the loss of a loved one. But when a fatal accident is caused by negligence, whether on a freeway, a surface street, or a commercial property, California’s wrongful death laws give surviving families the right to hold the responsible party accountable and recover the financial support they need to move forward.
