Plain-English glossary

Personal Injury Settlement Glossary

Every entry answers two questions: what the term means in plain English, and how it changes how much money you actually walk away with. Built for claimants, not law students.

Most legal glossaries copy each other’s definitions. They tell you that “pain and suffering” is “non-economic damages awarded for physical and emotional harm,” then stop. That technically-correct definition does not answer the question every injured claimant actually has: how does this term change what I get?

Each entry below has three sections: plain-English definition, how it works in practice, and the dollar-recovery implication. Sourced from primary statutes, federal regulations, and industry research where applicable.

Settlement Process

Negotiation, settlement structure, and post-settlement realities.

Damages

Categories of money you can be awarded — economic, non-economic, and punitive.

Fault & Liability

How fault is assigned and how it changes what you recover.

Insurance

Policy types, limits, and concepts that determine where the money comes from.

Medical Lien

also: Letter of Protection (LOP), Hospital lien

A medical lien is a legal claim that a hospital, doctor, or health insurer has on the proceeds of a personal injury settlement to recover medical costs they paid or extended on the claimant’s behalf.

Read entry

Personal Injury Protection (PIP)

also: PIP, No-fault insurance

Personal Injury Protection (PIP) is a type of auto insurance coverage that pays the policyholder's own medical bills and lost wages after an accident, regardless of who caused it.

Read entry

Uninsured / Underinsured Motorist Coverage (UM/UIM)

also: UM, UIM

UM/UIM is auto insurance coverage on the claimant's OWN policy that pays for injuries caused by an at-fault driver who has no insurance (UM) or whose insurance is insufficient to cover the full damages (UIM).

Read entry

Policy Limits

also: Policy maximum, Coverage limits

Policy limits are the maximum dollar amounts an insurance policy will pay for a covered claim, usually stated as a per-person limit and a per-occurrence (or per-accident) limit.

Read entry

Bad Faith (Insurance Bad Faith)

also: Bad-faith failure to settle, Bad-faith claims handling

Insurance bad faith is the legal claim that arises when an insurance company violates its duty to deal fairly with its insured (or in some states, with the claimant), most often by failing to settle a clear-liability claim within available policy limits when settlement was reasonable.

Read entry

Subrogation

also: Right of subrogation, Subrogation claim

Subrogation is the legal right of an insurance company or other party that has paid for damages or losses to "step into the shoes" of the insured and recover those payments from the at-fault party.

Read entry

Medical

Medical terms that show up in PI claims, with the settlement angle.

Procedural

Steps in the claim and lawsuit process.

Why a glossary that talks about money

Standard legal glossaries (Black’s, Cornell LII, Wikipedia) own the “what does this term mean?” query. We don’t try to compete on that. We own a different question that legal glossaries don’t answer: given this term applies to my case, how does it change my settlement dollars?

Knowing that “Maximum Medical Improvement” means “the point at which further significant improvement is unlikely” is technically accurate but commercially useless to an injured person. Knowing that settling before MMI typically costs claimants 30–70% of their potential recovery is actionable.
