The short answer
Mediation is a negotiation led by a neutral mediator, who helps the parties reach a settlement but cannot impose one. Arbitration is a private trial before an arbitrator, whose decision is usually binding and very difficult to appeal.
Why it matters
Choosing between them, or being bound by a contract clause requiring one, changes cost, speed, privacy, and how much review is available if something goes wrong.
Where it fits in your case
Mediation can happen at any stage. Arbitration usually happens because a contract requires it.
What to expect
Mediation is voluntary in result. Nothing is binding unless the parties sign a settlement.
Arbitration clauses are enforced. Courts generally enforce agreements to arbitrate under federal and Illinois law.
Limited review. Arbitration awards can be overturned only on narrow grounds, such as fraud or an arbitrator exceeding authority.
Cost. Arbitration avoids some court costs but adds arbitrator and administrative fees.
Court programs. Some Illinois courts send smaller civil cases to court-annexed, nonbinding arbitration.
What to do now
Check every contract for arbitration, mediation, and forum clauses.
Prepare for mediation as seriously as for a hearing.
Know your walk-away number before mediation.
Weigh the loss of appeal rights before agreeing to arbitrate.
What we need from you
The contract, a summary of the dispute, key documents, and your settlement goals.
Common misconceptions
“Mediation means we have to settle.” It does not, though it often helps.
“We can appeal a bad arbitration award.” Grounds for challenge are very limited.
