Iniciar un arbitraje o mediación

Cómo resolver disputas mediante arbitraje o mediación sin ir a juicio.

Visión general

Arbitration and mediation are forms of Alternative Dispute Resolution (ADR) that can be faster, cheaper, and more private than court proceedings. Arbitration produces a binding decision (an award); mediation helps parties reach their own settlement with the help of a neutral mediator. Many commercial contracts contain arbitration clauses requiring disputes to be resolved this way.

Proceso paso a paso

1

Check for an ADR Clause

Review your contract to see if it contains an arbitration clause or mediation agreement. If it does, you may be required to use ADR before (or instead of) going to court. Even without a clause, you can agree to ADR at any time.

Consejos prácticos
  • Courts encourage ADR — unreasonable refusal to mediate can result in adverse costs orders
2

Choose a Provider

Select an arbitration institution (e.g., LCIA, ICC, CIArb) or a mediation provider (e.g., CEDR, CIArb). For lower-value disputes, consider small claims mediation (free through the court service).

Consejos prácticos
  • Consider the provider's rules, fees, and the expertise of their panel
3

Notify the Other Party

Send a written notice to the other party proposing ADR. For arbitration, this usually means serving a Notice of Arbitration. For mediation, write proposing mediation and suggesting providers and dates.

4

Appoint an Arbitrator or Mediator

In arbitration, the tribunal is usually one or three arbitrators, appointed by agreement or by the institution. In mediation, the parties jointly select a mediator. The mediator is neutral and does not impose a decision.

5

The Process

Arbitration follows a procedure similar to court (statements of case, evidence, hearing, award). Mediation is more flexible — typically a one-day meeting where the mediator facilitates negotiation through joint sessions and private meetings ('caucuses').

Plazo: Mediation: 1 day. Arbitration: 3–12 months.

Outcome

An arbitration award is legally binding and enforceable like a court judgment (under the Arbitration Act 1996). A mediation settlement is binding only if the parties sign a settlement agreement. If mediation fails, you can still go to court or arbitration.

Costes

Mediation (CEDR)From £1,500 + VAT per party per day
Small claims mediation (court)Free
ArbitrationVaries widely — £5,000 to £100,000+ depending on complexity

Advertencias importantes

An arbitration award is final — rights of appeal are very limited under the Arbitration Act 1996.

Mediation is voluntary — either party can walk away at any time (but courts may penalise unreasonable refusal).

Ensure any settlement agreement is properly drafted and signed by both parties.
