How long have you been practicing personal injury law?

I’ve been practicing personal injury law for over two decades. As a California injury attorney and co-founder of J&Y Law, I’ve dedicated my entire career to helping people who’ve been hurt due to someone else’s negligence. I’ve handled thousands of cases across California, from car crashes on the 405 to serious pedestrian injuries in downtown LA. This is all we do. Every case we take on is personal, and our team puts in the time, the strategy, and the heart to get our clients the justice they deserve.

What percentage of your cases are personal injury claims?

Nearly 100% of our cases at J&Y Law are personal injury claims. We focus entirely on injury law because that’s where people need advocacy the most, I think. As a personal injury law firm, we represent clients injured in car accidents, motorcycle crashes, truck collisions, slip and falls, dog bites, wrongful death cases, and more. Our entire legal team is built around this one mission, and that's getting justice for the injured. If you’re hurt and looking for a California injury attorney who lives and breathes this work, go with our firm here at J&Y Law.

What are some of your most memorable victories in personal injury cases?

We’ve had the honor of securing life-changing results for clients who’ve suffered major injuries. A few that come to mind is one case, where our client used her settlement money to pay for her sister's surgery. Another case, our client was able to use the $1.25m settlement to buy a house, get married, and start his life. In another, we won $5m against a major big box retailer, and even though our client may never walk the same way again, at least he's able to get a second chance at finding happiness. As a California injury attorney, those are the victories that matter most to me.

What is the most important piece of advice you would give to someone who has recently been injured?

Do not try and deal with the insurance company on your own. Their goal is to pay you as little as possible. Before you sign anything or give a recorded statement, talk to a personal injury law firm like J&Y Law. You don’t need to know the legal system, because our team does. Your only homework is to get healthy. We’ll handle the rest. The sooner you get experienced legal representation, the stronger your case will be and the more protection you’ll have from delay tactics and lowball offers.

How do you make sure clients feel supported during a difficult time?

We treat every client like family. That's not a slogan. That's genuinely a core value for our firm. When you’re injured, you’re dealing with more than just physical pain. You’re overwhelmed, stressed, and honestly vulnerable. That’s where we come in. Our job as your California injury attorney is to carry the legal and insurance burdens for you so you can focus on healing. We check in regularly, explain each step in plain English, and make sure you never feel alone. Whether it’s helping find support locally or making sure bills don’t pile up, we’re there for you every step of the way.

How often do you take cases to trial, and what is your success rate there?

We take cases to trial when it’s in our client’s best interest. While most personal injury claims settle, not all insurance companies play fair. At J&Y Law, we prepare every case like it’s going to trial, and that preparation pays off. Overall, we have a 98% success rate. When insurers see that you have a serious California injury attorney who’s ready to go the distance, they often back down. That's the difference between hiring an attorney and going at it alone. Our trial track record reflects our commitment to getting justice when financial restitution isn’t enough.

How do you prepare a case for trial?

Trial preparation starts the moment we take your case at intake. At J&Y Law, we gather every piece of evidence, from photos and witness statements, to medical records and and expert opinions. We build a timeline, analyze liability, and prepare compelling visuals for the jury. We even use AI tools to look for gaps in treatment and other discrepancies in documentation. As a personal injury law firm, we use every fact and expert we can to strengthen your case. Our team rehearses every argument, anticipates defense tactics, and ensures that your story is told powerfully and clearly. The key to success in court is preparation and pursuing every angle possible, every single time.

How do you estimate the value of a personal injury claim?

This is probably the #1 question we get here at J&Y Law from new clients. So we estimate the value of a personal injury claim based on several key factors. These include your medical expenses, lost income, future care needs, and the pain and suffering you’ve endured. As a California injury attorney, I also consider how the injury impacts your daily life and long-term well-being. Every case is unique, so we take time to fully understand your losses. We also factor in the strength of the evidence and potential jury verdicts in your area. Our goal is to recover the maximum amount the law allows. That's called "maximum policy limits." If we can combine multiple policies, even better!

What are some problems or challenges that you’ve encountered in bringing personal injury claims, and how have you handled them?

One of the biggest challenges we face is insurance companies that delay, deny, or devalue legitimate claims. At our firm, we’ve had cases where insurers tried to blame our clients or claimed the injuries weren’t serious. You have to meet them head-on, so we respond with medical evidence, expert testimony, and aggressive negotiation. If that doesn’t work, we take the case to trial. We also help clients overcome challenges like getting medical treatment without upfront costs or dealing with uncooperative defendants. We’re problem-solvers here at J&Y Law.

What are some factors that you consider when advising clients who are deciding whether to take a settlement or go to trial?

When advising clients on if they should accept the settlement offer or take their case to trial, we look at the strength of the evidence, liability issues, and the insurance company’s offer. We also consider your medical recovery timeline, financial needs, and your ability to wait for a verdict. As a California injury attorney, I explain the risks and benefits of both paths in plain terms. Sometimes, taking a fair settlement is the best move. Other times, we need to go to court to get justice. We make sure you feel confident in whatever decision you make. Because it's your decision. We're here to support you no matter what.

Do you work on a contingency fee basis, and how is the contingency fee calculated?

Yes. J&Y Law works on a contingency fee basis, which means you pay nothing upfront. We only get paid if we win your case. Our fee is a percentage of the total recovery, and that depends on whether the case settles, goes to trial, and how long it takes. This fee structure allows anyone to access a top personal injury law firm without worrying about costs. As your California injury attorney, if we don’t win your case, you owe us nothing. That’s our promise.

What other costs beyond the attorney fee might be involved in a case, and how are these costs handled?

Beyond our attorney fees, there can be costs to build your case like expert witnesses, court filings, medical records, or accident reconstruction. At J&Y Law, you don’t have to pay out of pocket for these things though. If we win your case, those costs are reimbursed from the settlement. If we don’t win, you owe nothing. As a personal injury law firm, we believe no one should be denied a chance at getting justice just because they can’t afford the process.

Have you handled cases involving bad faith or other misconduct by insurers?

Of course, we’ve handled many cases where insurers acted in bad faith. That includes delaying claims without reason, denying coverage they owed, pressuring injured people to accept unfair offers, or worse! At J&Y Law, we don’t tolerate these tactics. As California injury attorneys, we hold insurance companies accountable when they cross the line. We’ve filed lawsuits for bad faith and won damages for clients who were mistreated. No one should be bullied after an injury. We'll fight back for you.

What is the slip and fall law in California?

In California, slip-and-fall cases fall under premises liability, a type of negligence claim. The injured person must prove the property owner or occupier had a duty of care, breached that duty, and caused harm. Property owners must maintain safe conditions and fix or warn about known hazards. They can be liable if they knew or should have known about a dangerous condition and failed to act. California follows pure comparative negligence, so compensation can be reduced by your share of fault. J&Y Law can help you navigate your rights with an experienced slip and fall lawyer. You generally have two years to file a claim after the date of your injury.

What is the average payout for traumatic brain injury?

There’s no fixed average payout for a traumatic brain injury in California because every case is unique. At J&Y Law, our traumatic brain injury lawyers have seen mild TBI cases settle from $250,000 to $1 million, while severe cases can exceed $5 million, especially if long-term care or permanent disability is involved. Key factors include medical costs, lost income, future care, and pain and suffering. California juries often award more in severe cases with strong evidence. The best way to estimate value is through a case review. So if you're still struggling with a TBI, let J&Y Law fight to get you what you're owed.

How to negotiate a slip and fall settlement?

Negotiating a slip and fall settlement starts with evidence and a strong demand letter. See a doctor right away and document your injuries, bills, and how your life is affected. Take photos, gather witness statements, and keep all records. Once you're settled into treatment, send a detailed demand letter to the insurer. Expect a low first offer. Don’t rush. Counter with proof of liability and damages. Be patient, and don’t settle until you know the full extent of your losses. A skilled slip and fall attorney at J&Y Law can handle negotiations and fight for the compensation you deserve not just today, but for the care you may need 25 years from now.

Biography

I’m the Co-Founder and Co-CEO of J&Y Law and Abogados Campeones, the Spanish-language division of our firm in Los Angeles. I was born and raised in LA, earned my degree from UCLA, and continued my education at Loyola Law School. Even before becoming a personal injury attorney, I was committed to assisting individuals who had suffered serious injuries, and that commitment laid the groundwork for my career.

After completing law school, I began practicing civil litigation with a focus on personal injury. Eventually, I teamed up with my business partner, Yosi Yahoudai, to establish J&Y Law. Together, we created a California-based law firm dedicated to standing up for injury victims and ensuring they are not overpowered by insurance companies or large corporations.

I work on a wide range of personal injury cases, including those involving catastrophic injuries and wrongful death. My main goals are straightforward: helping clients heal, safeguarding their rights, and working hard to maximize the value of each case within the framework of California law.

When I’m not in the office, I dedicate time to the community through Fix’n Fidos, a nonprofit organization focused on animal welfare that I support. Giving back, whether through my legal work or community involvement, is an essential part of my life.

Q. Is it normal for personal injury case delays in California?: May 19, 2026; A: California personal injury cases can take time. Your attorney likely waited until you reached Maximum Medical Improvement before they sent out the demand. That part was probably handled correctly because settling too early can leave you stuck paying paying for future medical expenses out-of-pocket.

What would concern me more is the communication and file handling. If you already provided records once and were asked for them again later, or if you were able to get records faster yourself than the law firm could, that’s usually a sign the file may not be getting enough attention internally.

At this point, I’d stop relying on phone calls and send an email asking: Was the demand actually sent? On what date? For how much? Has the insurance company responded at all? Ask for a copy of the demand letter too. You’re entitled to see what was submitted on your behalf.

You always have the right to get a second opinion or change attorneys. In California, attorneys have an ethical obligation to keep clients informed about their case. If communication has broken down and you don’t feel confident your case is moving properly, it’s okay to speak with another attorney before more time passes.

I hope everything works out for you on your case. ... Read More

Q. How to dispute fault assignment and address insurance rate increase after car accident in California?: May 19, 2026; A: You've got the sequence of events working in your favor. Your insurance company initially told you the other driver was at fault, directed you to move forward with repairs, and gave you the impression reimbursement would happen. Then they reversed course after the fact. That’s why you need to stop handling this over the phone and put everything in writing.

I would request a written explanation for why fault changed, ask for a copy of the full claim file, and specifically ask whether a supervisor reviewed the dash cam footage. Your video evidence is valuable because it creates an objective timeline instead of just competing statements between drivers.

You should also challenge the rate increase separately. In California, insurers generally cannot surcharge you for an accident where you were not principally at fault. If the rate increase is tied to this disputed determination, that needs to be addressed directly.

If your dash cam footage clearly shows the other driver caused the crash, you can pursue the other driver’s insurance directly, and if necessary, pursue the driver personally in small claims court. I've seen a lot of situations where insurance companies become much more cooperative once they realize the person they’re dealing with is serious and willing to take the case to trial if needed.

People make the mistake of trusting verbal assurances. Insurance companies document everything internally, and you should too. Dates, names, emails, claim numbers, recordings, screenshots. Build the paper trail now before more time passes. I hope everything works out for you. ... Read More
