Arbitration and mediation after a car accident: who decides
Short answer
In mediation, nobody decides for you.
- A mediator helps both sides try to settle, and nothing is binding unless you agree.
- Arbitration ends in a decision.
- In New Jersey, arbitration is mandatory for car crash lawsuits, but the award isn't binding: either side can demand a trial within 30 days.

Which one are you in?
Pick the one that fits. It shows the rule that applies and what you can check yourself. It can't tell you whether to accept an offer or an award, what your claim is worth, or what to do in your own case.
- What it is
- Both sides present their case, and the arbitrator gives a non-binding decision and a written award, usually the day of the hearing.
- Why it matters
- Arbitration is mandatory statewide for automobile negligence and personal injury cases.
- The rule
- A party rejects the award by filing and serving a demand for a trial de novo within 30 days. The court is very strict about it. Without one, the award can become a judgment.
Keep the written award, and note the day it was given.
- What it is
- The case goes on toward a trial, as if the arbitration hadn't decided it.
- Why it matters
- The court's arbitration award isn't binding on either side.
- The rule
- A party that demands a trial and doesn't significantly improve its position may owe costs, including the other side's attorney fees up to $750 and witness costs up to $500.
Ask what the award said, and who filed the demand, and when.
- What it is
- A mediator helps both sides talk about settling, and does not make a decision about the outcome.
- Why it matters
- Judges, court staff or the parties themselves can pick a case for mediation.
- The rule
- Mediators serve the first 2 hours free, including a first 1 hour session. After that, the parties share the mediator's market rate fee. If the case isn't resolved, it stays on the court's docket.
Ask how the mediator's fee will be split after the free hours.
- What it is
- Either side can take a PIP dispute to dispute resolution, run by an organization the state designates.
- Why it matters
- An insurer that denies a PIP claim must do it in writing, with reasons.
- The rule
- A lawsuit against your own insurer for unpaid PIP benefits goes to the courts' mandatory arbitration.
Keep the denial letter. The PIP denied guide says what happens next.
- What it is
- The parties agree to have their case heard by an arbitrator instead of a court.
- Why it matters
- Unlike the New Jersey courts' program, binding arbitration decides the case like a court would.
- The rule
- Decisions in binding arbitration are binding just like a court case, and pursuing a claim there keeps it out of the court system.
Read the arbitration clause in the contract or policy, and who it says picks the arbitrator.
Mediation vs. arbitration: who decides
Both are ways to settle a dispute outside a trial. The difference is who has the last word.
A neutral person helps both sides look for a settlement. Mediation is non-binding, and a resolution can't be imposed on either side. If they can't agree, the mediation ends.
The parties have their case heard by an arbitrator instead of a judge. Binding arbitration decides it like a court. New Jersey's court arbitration doesn't bind either side.
Most lawsuits never reach a trial. In 2005, trials were about 3% of the civil cases state courts closed, the Bureau of Justice Statistics found.

NJHow long mediation takes, and what it costs, in New Jersey's courts
How long a mediation runs depends on the case. The courts' program sets how it starts and who pays.
Mediators serve the first 2 hours on a case without charge, including that first session.

Neither process takes the decision away from you in New Jersey's courts. Here's what to keep track of.
- DoKeep the written award, and note the day it was given.
- DoAsk before a mediation how the mediator's fee will be split after the free hours.
- DoRead any arbitration clause in your policy or a contract you signed.
- Don'tDon't let the deadline to reject a court arbitration award pass by accident. The court is very strict about it.
- Don'tDon't read a posted mediation result as a value for your claim. Firms post their wins.

Turning it down means a trial. A party that doesn't significantly improve its position may owe the other side's attorney fees and witness costs.
