# ADR (alternative dispute resolution): definition and example

Any way of settling a dispute without going to court, such as negotiation, mediation, adjudication or arbitration.

Guidance for England and Wales. Check the contract, amendments and facts that apply to your job.

## What it means in practice

Read this alongside [the Pre-Action Protocol for Construction and Engineering Disputes](<https://www.justice.gov.uk/courts/procedure-rules/civil/protocol/prot_ced>).

Alternative dispute resolution describes several processes with different effects. Negotiation and mediation seek agreement, while adjudication and arbitration involve decisions by a third party. Choosing a process depends on urgency, enforceability, evidence, cost and the agreement between the parties.

Organising the disagreement through a [claim viability review](<https://www.quantsurv.com/claim-viability-review>) can help identify a proportionate route. Check any contractual procedure before committing to a process.

## Worked example

### The facts

Two businesses disagree about the value of an unfinished decorating package.

### What happens

1.  They exchange a short schedule of agreed and disputed items.
    
2.  They consider whether a facilitated settlement discussion could resolve the remaining differences.
    

### What this shows

The process is chosen around the dispute, rather than assuming every disagreement needs the same formal procedure.
