Define the question tightly enough that the expert can determine it without becoming the whole dispute system.

A valuation dispute may be appropriate where the contract requires a qualified valuer to determine a defined figure using stated assumptions. A broad shareholder dispute involving contractual interpretation, director duties and allegations of bad faith may not be suitable for the same professional mechanism merely because value is one part of the disagreement.

Specialist competence is central. A Neutral with broad commercial experience should not accept a formal engineering, accounting or actuarial determination unless the professional actually has the expertise required. Independence and expertise are separate appointment questions, and both matter.

The source of authority should be identified exactly. The parties may appoint by contract, later agreement or another valid mechanism. The expert should know whether the terms of reference can modify the original clause and whether any matter is expressly excluded from determination.

Procedure should be proportionate. A highly technical question may require document exchange, site inspection or specialist submissions. The expert should not copy a full arbitral procedure automatically if a shorter professional process is sufficient.

Fair participation still matters. Even where the process is informal, parties should understand what material the expert will consider and have the opportunity required by the governing framework. The professional should not receive decisive substantive information from one party without considering the procedural implications.

Reasons should be addressed in advance. Some contracts require a reasoned determination; others may contemplate a concise result. The engagement should avoid a later dispute about whether the expert must explain methodology or respond to every argument.

Private legal advice remains separate. If a legal interpretation question affects the determination, the expert should understand whether the role permits deciding that issue or whether local counsel or another forum must address it. Expertise in the subject does not automatically create legal authority.

Conflicts analysis should include parties, affiliates, advisers, experts and repeat appointing relationships. Specialist communities can be small, so prior professional contact is common. The issue is not to treat every contact as disqualifying, but to make relevant relationships visible.

Fees and deposits should be structured so the expert can complete the work without appearing controlled by one party. Where a contract assigns payment initially to one side, the professional terms should still preserve independent judgement.

Closure should identify delivery, correction of obvious clerical error if permitted, record handling and whether the expert can take any later role. The professional should not drift from determiner into adviser or arbitrator without fresh authority and conflicts review.

The expert should be able to identify a material ambiguity in the question without automatically rewriting the parties' contract. The terms can provide a route for clarification, agreed amendment or referral back to the appointing parties. This protects the expert from deciding a different question merely because the original wording was poor.

The same applies to insufficient information. A determination may depend on records one party does not possess, a site condition that can no longer be inspected or a valuation assumption the parties have not agreed. The terms should explain whether the expert can request further material, draw any inference or pause for clarification under the governing framework.

Where the expert needs a separate specialist input, that should be transparent. One professional may be qualified to determine the core issue while needing another discipline for a subsidiary question. The terms should identify whether such input is permitted, who appoints the specialist, how cost is handled and whether parties can comment.

Corrections after issue should be narrow. If the governing framework permits correction of clerical or computational error, the terms should distinguish that from reopening the merits. A closed determination should not become an endless reconsideration process simply because one party dislikes the result.
