You have a dispute that the contract says must go to arbitration, but before you file, the agreement requires something else first: mediation. Skip that step and you risk having your arbitration demand rejected, stayed, or dismissed as premature — and you pay the filing fees twice. Send a proper formal notice initiating contractual mediation prior to arbitration, and you preserve your right to arbitrate while creating a genuine chance to resolve the matter without it.
The notice itself is not a demand letter. It is a procedural document with specific elements that a mediator, an arbitration administrator, and eventually an arbitrator will all review. It has to identify the agreement, the clause you are invoking, the dispute, the relief you want, and the process you propose — in that order, and without arguing the merits.
The steps below walk through the clause, the notice, the mistakes that invalidate one, and what to do when the other side refuses or goes silent.
Warning: Dispute resolution provisions are enforced according to their exact terms, and courts routinely dismiss arbitrations filed before a required mediation step. Have qualified counsel review your notice and your compliance timeline before you send it.
Why Does a Mediation Notice Before Arbitration Matter?
A mediation notice is a condition precedent in most well-drafted contracts. It is not a courtesy. If your agreement says the parties "shall" mediate before arbitrating, a failure to do so gives the other side a procedural defense that can delay your case by months.
There are three practical reasons the step is worth taking seriously, not just technically satisfying.
- It preserves your arbitration right. A documented mediation attempt closes off the argument that you failed to satisfy a contractual prerequisite.
- It often settles the dispute. A large share of commercial matters resolve at or shortly after mediation, before the arbitration fees, arbitrator selection, and discovery costs begin.
- It produces information. Even when mediation fails, the exchanged statements and document submissions frequently narrow the issues and reshape the arbitration demand you eventually file.
- It starts the clock in your favor. Most clauses specify a mediation period, such as thirty or sixty days, after which either party may proceed to arbitration. Your notice starts that period.
- It costs far less than the alternative. A mediator's hourly fee is a fraction of an arbitration panel's, and the process typically takes days rather than months.
There is also a strategic dimension. A party that refuses a reasonable mediation request looks unreasonable to a future arbitrator, and that impression can affect both cost allocation and the panel's receptivity to procedural motions.
Read the Dispute Resolution Clause Before You Send Anything
Your notice has to track the clause, not a generic template. Pull the agreement and extract six specific items before you draft a sentence.
- The mediation requirement itself. Note whether mediation is mandatory ("shall") or permissive ("may"). Only a mandatory clause creates the notice obligation.
- Any waiting period. Identify the minimum number of days that must pass after the notice before arbitration may be commenced.
- The notice mechanics. Confirm the required recipient, delivery method, and address. Notices sent to the wrong party or by the wrong method are often treated as ineffective.
- The mediation administrator or rules. Many clauses name a specific provider or a set of mediation rules. Your notice should reference them.
- Mediator selection procedure. Note who proposes, who selects, and what happens if the parties cannot agree.
- Location and language. Confirm the specified seat or venue and the governing language of the proceedings.
If the clause incorporates institutional rules, obtain those rules and follow their commencement format. Institutional notices that omit required elements are frequently returned for correction, and that correction period can consume your deadline.
Pro Tip: Quote the dispute resolution clause verbatim in your notice, then state in one sentence that you are invoking it. Quoting removes any argument later about which clause you meant.
Formal Notice Templates Initiating Contractual Mediation
The first template is a standard cooperative notice suitable for a mandatory mediation clause with a defined waiting period. The second is a firmer version for a counterparty that has already signaled it will resist. The third is a proposed joint submission you can send once the other side engages.

Common Mistakes That Invalidate a Mediation Notice
Most notices that fail do so on procedure, not substance. Review your draft against the following before it goes out.
- Arguing the merits. A mediation notice is not the place for your strongest advocacy. Detailed factual arguments harden positions and reduce the chance of settlement.
- Omitting the quoted clause. Without the verbatim clause, the recipient can claim it does not know which provision you are invoking.
- Failing to state the relief sought. Mediators and arbitrators both need to understand what outcome you want.
- Not naming a mediator or a selection method. Leaving selection entirely open invites delay.
- Sending to the wrong recipient. Use the notice address specified in the agreement, and copy any additional parties the agreement identifies.
- Setting a deadline shorter than the clause permits. If the clause provides for a defined mediation period, your notice must operate within it.
- Threatening arbitration in the first paragraph. A single reference to the next step is appropriate. Repeated threats read as bad faith.
- Failing to state that no waiver is intended. Every notice should reserve rights, claims, and defenses.
- Letting the waiting period expire without documenting it. Once the period runs, send a short written follow-up recording that the requirement was satisfied.
- Signing without authority. Confirm that the signatory has authority to bind the company to a settlement.
Pro Tip: Keep the notice under two pages. Long notices read as opening briefs and push the other side toward litigation posture rather than toward a settlement conversation.
What To Do If the Other Party Refuses or Ignores the Notice
Both responses are common, and both have a defined next step. What matters is that the record shows you made a proper, timely attempt.
If the other party refuses, ask for the refusal in writing and confirm that you consider the mediation condition satisfied. Then proceed under the agreement's next step, whether that is a notice of arbitration or a filing with the designated administrator.
If the other party goes silent, send one short follow-up after your stated response period passes. Restate the request in three sentences, note the date of the original notice, and state that you will treat the mediation requirement as satisfied by your notice if there is no response.
If the other party engages but stalls on logistics, propose a mediator unilaterally and set a date. Delaying is a strategy, and the way to defeat it is to keep advancing a specific proposal rather than waiting for agreement.
In every case, preserve the notice, the delivery receipt, any response, and a one-page chronology. When you file for arbitration, that chronology demonstrates that the prerequisite was met and removes the other side's easiest procedural argument.
Warning: Do not begin arbitration before the contractual mediation period expires, even if the other side has clearly refused. Filing early can result in the arbitration being stayed or dismissed, and the fees incurred in the interim are rarely recoverable.
Frequently Asked Questions
Q: What is a formal notice initiating contractual mediation prior to arbitration?
A: It is a written notice that invokes the mediation provision of an agreement and triggers the pre-arbitration mediation requirement. It identifies the agreement and clause, describes the dispute and the relief sought, proposes the mediation process, and reserves all rights, so that the contractual condition is satisfied before arbitration begins.
Q: Is mediation required before arbitration in a commercial contract?
A: Only if the agreement says so. A clause using "shall" or "must" generally creates a mandatory condition precedent, while permissive language using "may" does not. If the clause is mandatory, failing to mediate can give the other party grounds to challenge a later arbitration filing.
Q: What must a mediation notice include?
A: Include the identity of the parties, the agreement and the specific dispute resolution clause quoted verbatim, a neutral description of the dispute, the relief sought, a proposed mediator or selection method, a proposed timeline, and a reservation of rights. A request for a designated representative with settlement authority is also helpful.
Q: How long should the other party have to respond to a mediation notice?
A: Follow whatever response or waiting period the dispute resolution clause specifies. Where the clause is silent, a response window of five to ten business days is common, and the notice should state clearly what will happen if no response is received.
Q: Can I skip mediation and file for arbitration directly?
A: Not if the agreement makes mediation a required step before arbitration. Filing early can result in the arbitration being stayed or dismissed as premature, and the fees you have already paid are typically not recoverable. Satisfy the mediation condition first, then proceed.
Q: What should I do if the other party refuses to mediate?
A: Request the refusal in writing and confirm that you consider the mediation condition satisfied by your notice. Then proceed to the next step under the agreement, and preserve the notice, the delivery receipt, and the refusal so the record shows a proper pre-arbitration attempt.
