Introduction
JAMS is one of the best-known providers of mediation and other alternative dispute resolution services in the United States. But many people searching for “JAMS mediation rules” discover an important problem: there is not one current, general U.S. JAMS mediation rulebook that works like JAMS’ Comprehensive Arbitration Rules. That distinction can affect how your mediation is started, managed, and completed.
What Are the Current JAMS Mediation Rules?
For ordinary U.S. mediations, JAMS describes mediation as an assisted negotiation rather than a formal trial-like process. The parties and mediator agree on the procedures before mediation begins. There are generally no courtroom-style rules of evidence or rigid presentation requirements.
JAMS’ current public rules index separately lists JAMS International Mediation Rules. Those rules contain specific provisions covering mediator appointment, disclosures, representation, privacy, confidentiality, fees, withdrawal, and settlement. The International rules currently shown by JAMS date from August 1, 2011, so they should not be confused with a newly issued 2026 domestic mediation rule set.
Practical answer: Before assuming a particular JAMS rule applies, check your contract, mediation agreement, case documents, and the JAMS case manager’s instructions.
How Does JAMS Mediation Actually Work?
JAMS describes its normal mediation process in several stages. The parties select a neutral mediator, often after reviewing qualifications or interviewing potential neutrals. A preliminary call or meeting may then identify settlement issues, needed documents, and concerns about the process.
The mediation may begin with a joint session, followed by separate discussions. The mediator facilitates communication, identifies interests and settlement options, and may provide an evaluation of the dispute when appropriate. That evaluation is not binding unless the parties agree otherwise.
A major practical point is that the mediator does not decide the case. The parties decide whether to settle.
What Should You Give the Mediator?
JAMS’ July 23, 2026 guidance recommends treating pre-mediation communication as a settlement tool—not as another courtroom brief. It identifies four especially useful subjects:
Strengths: What facts, documents, rulings, or legal arguments help your position?
Weaknesses: What could go wrong for your side? Honest discussion of weaknesses can help the mediator test unrealistic expectations.
Past settlement efforts: Explain what was offered, what was rejected, and why negotiations failed.
Settlement barriers: Identify emotional, financial, business, relationship, authority, or other obstacles that could prevent agreement.
This is one of the simplest ways to make an expensive mediation more productive.
How Do You Contact JAMS Customer Service?
JAMS currently provides a centralized 1-800-352-5267 telephone number. Its online Contact Us system separates requests into New Case Inquiry, Case Related Support, Technical Support, and Other.
For an existing case, provide your 10-digit case reference number. JAMS specifically states that providing it helps the team assist you more quickly. Case-related support includes questions about documents and billing; technical support covers issues such as JAMS Access.
For a new mediation, JAMS’ online inquiry process lets you indicate a preferred location, practice area, service type, virtual/in-person/hybrid preference, requested dates, and even up to eight preferred neutrals.
What If You Cannot Upload or Find Your Case Documents?
JAMS provides a mediation document portal for active mediations. Only email addresses registered to an open case can upload documents, and JAMS instructs users who cannot see their case to contact their JAMS Case Manager.
Best solution: do not keep retrying the portal. Confirm that the correct email address is attached to the case and contact the case manager.
How Much Does JAMS Mediation Cost?
Do not rely on an old internet article quoting a single “JAMS mediation fee.” Mediation pricing can depend on the mediator, case, location, service format, and administrative arrangements.
For example, a JAMS page concerning a specific Data Privacy Framework program displays a $300 initial non-refundable mediation fee and identifies additional professional-time charges, but that page says it was updated August 30, 2023 and should not be treated as a universal 2026 JAMS mediation price.
The safest approach is to ask the JAMS case manager for a written current estimate, including mediator rates, administrative fees, deposits, cancellation/continuance charges, and who pays what.
What Happens After Settlement?
JAMS explains that once settlement is reached, the mediator can help finalize the settlement agreement and implementation procedures. JAMS’ mediation guide says the agreement is recorded for signature promptly to avoid later second thoughts.
For international mediations, the rule is explicit: the settlement is not legally binding under those rules until it is reduced to writing and signed by or for the parties.
Bottom Line
The biggest mistake is treating “JAMS mediation” as though it were automatically governed by one universal rulebook. JAMS mediation is intentionally flexible, while specific mediation agreements, contracts, applicable law, and specialized JAMS procedures can control important details.
For practical help, contact JAMS at 1-800-352-5267, use the appropriate online support category, keep your case reference number available, and get fee and procedural details in writing. Most importantly, prepare for mediation around both the strengths and weaknesses of your case and the real obstacles to settlement. That is where JAMS’ process can become a genuine problem-solving tool rather than simply another appointment on the litigation calendar.
