Mediation

A settlement conversation between two sides of a dispute, run by a neutral person who tries to help both parties agree on terms.

Collision Bureau is not a law firm and this is not legal or medical advice. It is general information about what happens after a crash. For advice on your situation, talk to an attorney licensed in your state or a treating clinician.

What it means

Mediation is a structured conversation between two sides of a disagreement, led by a neutral person called a mediator. The mediator does not decide anything. The mediator moves between the parties, carries offers back and forth, and tries to help both sides find a number or a set of terms both can live with. The result is a settlement or no settlement. There is no verdict and no ruling.

The point of naming it is to separate it from the two things people most often confuse it with. Mediation is not a trial, where a judge or jury decides the case. Mediation is not arbitration, where a private decider rules on it. Mediation is a negotiation with a neutral person steering the conversation.

How it works

Both sides agree on a mediator, or a court names one. The parties meet, in person or by video, often in separate rooms with the mediator moving between them. Each side presents its view of the facts and the value of the case. Offers and counteroffers travel through the mediator rather than directly across the table. If the sides reach terms, the terms get written up and signed before the room clears. If they do not, the case continues wherever it was before the session began.

Communications inside the session are commonly treated as confidential, and the mediator does not report back to the court on what either side said. The specifics are governed by state law and by the written mediation agreement the parties sign at the start of the day.

Why it comes up

A crash claim that becomes a lawsuit often reaches mediation after discovery, once both sides know what the records say and what the witnesses have told them. Mediation also appears before a lawsuit is filed, when an insurer and a claimant have been talking for months and want a last structured attempt at terms. Many civil courts require mediation at some point on their docket. That is a general observation about how cases move, not a statement about any particular state. If a question about whether to ask an attorney comes up at this stage, that is normal.

What it is not

Mediation is not a hearing, not a deposition, and not a judgment. The mediator has no power to order anyone to do anything. Nobody wins mediation and nobody loses it. The session ends in signed terms, or it ends with the file in the same shape it was before anyone walked in.

Questions people actually ask

01Is mediation binding?

The session itself is not. The mediator decides nothing, and either side can walk away without an agreement. What becomes binding is any written settlement the parties sign at the end of the day, which is a contract like any other. The exact enforceability of that contract, and what happens if a party changes its mind, are questions set by state law and by the mediation agreement, which is why an attorney licensed in your state is the person who answers them for your situation.

02How is mediation different from arbitration?

An arbitrator hears both sides and decides the case, often with the authority of a court ruling. A mediator does not decide anything. The mediator carries offers between the parties and tries to help them find terms both can accept. Arbitration ends in a result that gets imposed. Mediation ends in a result both sides agreed to, or in no result at all. The two words sound similar and describe very different rooms.

03Does what I say in mediation become evidence?

As a general matter in most places, communications made in mediation are treated as confidential and are not admitted as evidence in a later proceeding on the same dispute. The specific rules are set by state law and by the written mediation agreement the parties sign at the start of the session, and the scope of the confidentiality can vary. What any of that means for your file is a question for an attorney licensed in your state.
