Quick Answer

A well-drafted arbitration clause needs to specify at minimum the seat of arbitration, the applicable rules or institution, the number of arbitrators, and the language of proceedings — vague or incomplete clauses ("pathological clauses") can create disputes about the arbitration process itself before the underlying dispute is even addressed. Reviewing a proposed clause with a lawyer before signing is far cheaper than fixing a defective one later.

Quick Facts

Key elements to specify
Seat of arbitration, applicable rules/institution, number of arbitrators, language of proceedings, and scope of disputes covered
Risk of an incomplete clause
A 'pathological clause' can itself become a source of dispute, delaying resolution of the actual underlying disagreement
Who this applies to
Businesses negotiating a contract with a foreign counterparty who want arbitration as the dispute-resolution mechanism
Typical first step
Decide, in principle, whether arbitration actually suits the type of contract and counterparty involved

Your Options

Use a model clause from a recognised institution

Institutions like the ICC publish recommended model clauses, a reliable starting point that avoids common drafting errors.

Customise carefully for the specific relationship

Adjust the seat, rules, and other elements to fit the specific parties and contract, rather than a generic template.

Have the clause reviewed by a lawyer before signing

A short review at the drafting stage is far cheaper than resolving ambiguity once a dispute has actually arisen.

Steps to Take

  1. 1

    Decide whether arbitration suits the contract

    Not every commercial relationship benefits equally from arbitration over litigation.

  2. 2

    Choose the seat of arbitration

    Affects which national arbitration law applies and the degree of court oversight available.

  3. 3

    Choose the applicable rules and institution, if any

    Institutional rules (e.g. ICC) provide administrative support; ad hoc arbitration under UNCITRAL rules is also possible.

  4. 4

    Specify the number of arbitrators and the language of proceedings

    Both have real practical and cost implications.

  5. 5

    Get legal review of the drafted clause before signing

    To catch ambiguity or internal inconsistency before it becomes a real problem.

Documents You May Need

  • The draft contract containing the proposed clause
  • Any model clause from the relevant arbitration institution
  • Information about the counterparty and the nature of the underlying relationship
  • Any prior correspondence about the dispute-resolution mechanism
  • Corporate/identity documentation

Common Mistakes to Avoid

  • Copying a clause from an unrelated contract without adapting it
  • Leaving out the seat of arbitration or the number of arbitrators
  • Specifying inconsistent or contradictory rules and institutions
  • Not considering whether the clause covers the full range of disputes that could arise

Risks & Deadlines

A defective clause can itself become the subject of a dispute

Requires legal review at drafting stage — an ambiguous or incomplete ('pathological') clause can delay resolution of the real underlying dispute by years.

The seat choice has consequences beyond the clause itself

Requires legal review for the specific choice — it determines which national arbitration law and courts have a supervisory role over the process.

Estimated Costs

  • Legal review of a draft clause: Varies by lawyer — ask for a quote upfront, but typically modest relative to litigation costs it can help avoid
  • Full contract negotiation support, if needed: Varies by lawyer and complexity — ask for a quote upfront
  • Later dispute resolution, if the clause becomes contested: Requires legal review — depends on the country and complexity

When to Contact a Lawyer

  • You're negotiating a contract with a foreign counterparty and considering arbitration
  • You've been given a draft arbitration clause and want it reviewed
  • You're unsure which seat or institution suits your specific situation
  • An existing clause's validity or scope is now being disputed

Frequently asked questions

It's a reasonable starting point but shouldn't be used unadapted — the seat, rules, and other elements should fit the specific relationship and counterparty, not just be copied wholesale.

No — the seat is a legal choice, often a neutral third country, and doesn't need to relate to either party's location or where hearings actually happen.

It can lead to a dispute about the arbitration process itself — whether it's valid, which rules apply, or which institution has authority — before the real underlying disagreement is even addressed.
