A lawyer should not take any improper action or even suggest the appearance of being improper.

Mandate – A command issued by a court directing a judgment, sentence, or decree enforcement.

Maximum Medical Improvement (MMI) – MMI is when an injured person’s condition stabilizes, and no further improvement or recovery is expected, even with additional care and treatment. In simpler terms, it means the injury has recovered as much as possible. This term is commonly used in workers’ compensation cases, where temporary benefits are provided until the patient reaches MMI. At this point, the patient is assessed for permanent disability and any further benefits. Insurance companies typically stop paying for treatments if a doctor believes the condition cannot improve.

Asbestos, a microscopic fiber known for its durability and resistance to fire and chemicals, was widely used in various commercial and industrial applications, including roofing shingles, floor tiles, and automotive parts.

Motion – A motion is a formal request made to a judge to issue a ruling or take some action. The judge may either grant or deny the request.


Named Insured – The named insured is any individual whose name appears on the insurance policy itself, as opposed to those who may be covered under the policy but are not explicitly named.

Negligence – Negligence refers to the failure to use a reasonable degree of care given the circumstances. The four elements of negligence are a duty owed to a plaintiff, a breach of that duty by the defendant, proximate cause, and injury or damage suffered by the plaintiff. It is essentially carelessness.

The aim is to reach a final settlement amount that both parties agree upon.

This means one does not need to prove who was at fault or negligent to receive benefits or damages. See Limited Tort Insurance and Personal Injury Protection.

Statute of Limitations – The statute of limitations is a law that determines the period within which someone must file legal action, usually starting from the time the injury or damage occurs. In Pennsylvania, the statute of limitations for most personal injury cases is two years, unless the accident happened to a minor, who has two years after their 18th birthday to file a claim.

Strict Liability – Strict liability is a legal concept that extends responsibility for wrongdoing to another party regardless of their direct involvement in the incident. For example, if a car company manufactures a car with faulty brakes, and those brakes cause an accident, the car company could be held accountable for the accident due to strict liability.

Uninsured Motorist Coverage (UIM) – An addition to a standard automobile insurance policy that provides coverage if the other driver is at fault for the accident and is uninsured. It protects the insured party from having no coverage if an uninsured driver crashes into them.


Verdict – A verdict is a formal decision about the outcome of a case made by a judge or jury.

Workers Compensation – An insurance system by which state-required, no-fault benefits are provided by an employer to an employee—or the employee’s family—due to a job-related injury (including death) resulting from an accident or illness that happened at work.

Wrongful Death – A claim made on behalf of the survivors or beneficiaries of a person who has died as a result of wrongful conduct—either negligent or intentional.
