Answering your Questions
How long do I have to file a personal injury claim?
Ohio’s statute of limitations for most personal injury claims is two years from the date of the injury. Failing to file within this period may prevent you from recovering compensation.
This two-year window applies to most accidents and injuries, including car accidents, medical malpractice, and slip-and-fall incidents. Starting the process early ensures that your evidence is fresh, witnesses are available, and your case moves through the legal system within the appropriate time frame. Our experienced Ohio personal injury attorneys can help you make sure your claim is filed on time and that all necessary documents are in order.
What should I do after a car accident?
After a car accident, check for injuries and call 911. If you can, gather evidence, take photos, and exchange information with the other driver. Seek medical attention—even if you feel fine—and contact your lawyer to discuss your legal options.
It’s important to document everything from the scene of the accident. Photos of the accident site, vehicle damage, and any visible injuries can strengthen your case.
Even if you think your injuries are minor, some symptoms may appear later. Having medical records and accident reports on file can help support your claim. Our experienced firm can guide you through the process of filing a claim and fighting for fair compensation.
Who can be held liable for a defective product?
Manufacturers, distributors, and retailers may all be held responsible for injuries caused by a defective product. Liability depends on the specific defect and how the product was used.
For example, if a manufacturer produces a faulty appliance that causes burns, the manufacturer could be held liable. Similarly, if a retailer sells a product without proper warnings or instructions, they could also share responsibility.
In cases of defective products, proving the defect and establishing the chain of responsibility can be complicated. Our skilled product liability lawyer can help gather evidence, identify the liable parties, and pursue the compensation you deserve.
What is considered medical malpractice?
Medical malpractice occurs when a healthcare provider fails to meet the accepted standard of care, causing injury to a patient.
Examples include misdiagnosis, surgical errors, medication mistakes, and birth injuries.
In a misdiagnosis case, for example, a doctor may fail to identify a disease early enough, causing the condition to worsen. Surgical errors can involve mistakes made during an operation, like leaving a surgical instrument inside the patient.
Medical malpractice cases require proving that the healthcare provider did not meet the standard of care. Our seasoned personal injury team can help evaluate the circumstances of your case and get connected with the right experts to prove your claim.
What are signs of nursing home abuse or neglect?
Common signs include unexplained injuries, bedsores, malnutrition, sudden behavioral changes, and poor hygiene. If you suspect neglect or abuse, document your concerns and speak with an attorney.
If you notice sudden weight loss, frequent hospitalizations, or injuries that don’t make sense, those could be indicators of neglect or abuse. Bedsores are a clear sign that a resident may not be receiving adequate care or attention.
Taking action quickly can prevent further harm and help protect your loved one from continued abuse. Our Ohio personal injury lawyer can help you investigate the situation and hold nursing homes accountable for any negligence or abuse.
What is considered a catastrophic injury?
A catastrophic injury is one that causes permanent and severe damage, often leading to lifelong disabilities. These injuries include spinal cord injuries, traumatic brain injuries, severe burns, and amputations.
Catastrophic injuries can drastically change your life, requiring ongoing medical care and possibly preventing you from returning to work or leading an independent life. For example, a spinal cord injury might result in paralysis, requiring long-term care and specialized equipment.
These injuries can also lead to significant emotional and financial burdens. We have an attorney who specifically focuses his practice on catastrophic injury cases—call today for a free consultation.
What do I do if I’m in a truck or motorcycle accident?
If you are involved in a truck or motorcycle accident, seek medical attention immediately and contact the police. Be sure to document the accident scene, including taking pictures of the vehicles and any visible injuries.
Truck and motorcycle accidents often result in serious injuries due to the size and speed of the vehicles involved. In truck accidents, the driver, trucking company, or even the manufacturer of the truck part may be liable. Motorcycle accidents, due to the vulnerability of riders, often result in severe injuries such as broken bones, road rash, or brain injuries.
Our attorneys have recovered millions of dollars in compensation for auto accident clients, and we can help investigate the cause of your accident and fight for the compensation you deserve.
What if I was partially responsible for my slip and fall?
Yes, you can still file a claim if you were partially responsible for your slip and fall, but the compensation you receive may be reduced based on your percentage of fault.
In Ohio, the law follows a modified comparative negligence rule. This means that if you are less than 51% at fault for the accident, you can still recover damages, but your compensation will be reduced by the percentage of your responsibility. For example, if you were found 20% at fault for the fall, you would receive 80% of the total damages.
Our Ohio personal injury lawyers can help evaluate the circumstances, gather evidence, and fight to ensure you receive fair compensation even if you share some responsibility for the accident.
Can I sue for a dog bite injury?
Yes, if you were bitten by a dog, you may be able to file a lawsuit against the dog’s owner, especially if they were negligent in preventing the attack.
In Ohio, dog owners are generally liable for injuries caused by their dogs if the dog had a history of aggression or the owner failed to control the dog properly.
For instance, if a dog owner allowed their pet to run free in a public area, leading to an attack, the owner could be held responsible. Our dog bite attorney can help you gather evidence, negotiate with insurance companies, and fight for compensation for your medical expenses, emotional distress, and pain and suffering.
What is a wrongful death claim?
A wrongful death claim is filed when a person dies due to the negligence or wrongful actions of another. This could involve accidents, medical malpractice, or even criminal behavior.
For example, if a driver causes a fatal car crash due to speeding or drunk driving, the family of the deceased may file a wrongful death lawsuit. Wrongful death claims aim to provide compensation for funeral costs, lost income, and the emotional suffering caused by the death.
Our compassionate and award-winning team of Ohio lawyers can help you navigate the process and fight for justice on behalf of your loved one.
