Expert determination is one of the more specialised forms of Alternative Dispute Resolution (ADR). It provides a fast, confidential, and expert-led way to resolve disputes that turn on technical or valuation issues, rather than wider questions of law.

In an expert determination, the parties jointly appoint an independent specialist to decide a defined issue. It is particularly suitable for matters that depend on expert knowledge, such as valuing assets, interpreting technical data, or assessing professional fees, rather than determining broader legal arguments.

The appointed expert is usually a professional with relevant specialist experience, for example, an accountant, surveyor, engineer, or valuer. Their determination is generally binding, unless the parties agree otherwise before the process begins.

At Trinity ADR, our barristers can act as independent experts in suitable cases or assist in appointing the right specialist for the particular issue to be resolved. The process is entirely private and focused on efficiency, helping parties narrow down the issues with the help of a relevant expert and achieve a resolution that is both practical and proportionate.

Expert determination can often be concluded more quickly and at lower cost than arbitration or litigation, particularly where the issue is narrow or highly technical. It provides certainty and finality without the procedural formality, costs and delays of resolving a dispute at Court.
