When parties become embroiled in a serious conflict, they often seek to avoid the cost, delay, and public exposure of litigation by turning to alternative dispute resolution (ADR). The two most common forms are mediation and arbitration.
But what if you want the flexibility of mediation and the finality of arbitration?
A hybrid process known as med-arb combines elements of both.
Before deciding whether med-arb makes sense for your dispute, it’s important to understand the differences among mediation, arbitration, and hybrid ADR processes.

What’s the Difference Between Mediation and Arbitration?
Mediation
In mediation, a neutral, trained mediator helps disputing parties work toward a voluntary agreement.
- The mediator does not impose a decision.
- The process is typically confidential.
- The outcome is usually nonbinding unless formalized in a settlement agreement.
- The focus is on interests, communication, and creative problem-solving.
Ideally, mediation produces a sustainable agreement that parties willingly follow because they helped shape it.
Arbitration
In arbitration, a neutral arbitrator acts more like a private judge.
- The arbitrator hears evidence and arguments.
- The arbitrator renders a decision (called an award).
- The outcome is typically binding and enforceable.
- Appeal rights are extremely limited.
- Proceedings are generally confidential.
Unlike mediation, arbitration removes decision-making power from the parties.
Why Consider a Hybrid Process?
Both mediation and arbitration are effective—but each has limitations.
Mediation drawback: It can end in impasse.
Arbitration drawback: Parties lose control over the outcome.
If parties want the opportunity to negotiate—but also want certainty that the dispute will be resolved—med-arb offers a middle ground.
How Does Med-Arb Work?
In a med-arb process, parties first agree—usually in writing—that:
- They will attempt mediation first.
- If mediation fails, arbitration will follow.
- The arbitration outcome will be binding.
The process unfolds in two stages.
Stage 1: Mediation
The neutral mediator facilitates negotiation as in a traditional mediation. This may include:
- Joint sessions
- Private caucuses
- Proposal testing
- Structured problem-solving
If the parties reach agreement, the process ends there.
Stage 2: Arbitration (If Necessary)
If mediation reaches impasse—or if certain issues remain unresolved—the process shifts to arbitration.
At this point:
- The mediator may assume the role of arbitrator (if qualified and agreed upon), or
- A separate arbitrator may take over the case.
The arbitrator then renders a binding decision—either on the entire dispute or on the remaining unresolved issues.
The key feature: The dispute will be resolved one way or another.
The Benefits of Med-Arb
In practice, many med-arb cases conclude during the mediation phase. Why?
Because the possibility of binding arbitration often motivates parties to compromise.
This dynamic makes med-arb particularly useful when:
- There is a hard deadline (e.g., labor disputes, commercial shutdown risk).
- Ongoing relationships must be preserved.
- Parties want efficiency and finality.
- Litigation would be costly or disruptive.
Med-arb can also be cost-effective. If one neutral serves in both roles, the arbitration stage can proceed quickly without restarting fact development.
Potential Pitfalls of Med-Arb
Despite its advantages, med-arb raises legitimate concerns.
- Confidentiality Concerns
In mediation, parties often disclose confidential information in caucus.
If the mediator later becomes the arbitrator, parties may worry that:
- Confidential information could influence the arbitration award.
- The neutral may struggle to “unlearn” what was shared privately.
This concern may cause parties to withhold information during mediation—undermining its effectiveness.
One solution is to use separate individuals for mediation and arbitration. However, this increases time and cost.
- Pressure to Settle
Because arbitration is binding, parties may feel pressure to settle in mediation—even if the agreement is not ideal.
The looming arbitration stage can shift negotiations from collaborative problem-solving to risk avoidance.
What About Arb-Med?
A lesser-known hybrid is arb-med, which reverses the sequence.
In arb-med:
- The neutral first conducts an arbitration hearing.
- The arbitrator writes a binding award—but keeps it sealed.
- The neutral then attempts to mediate a voluntary settlement.
- If mediation fails, the sealed award is released.
According to Richard Fullerton in the Dispute Resolution Journal, this structure eliminates the concern that confidential mediation disclosures will influence the arbitration award.
However, arb-med introduces other challenges:
- The neutral cannot revise the sealed award if new insights emerge during mediation.
- The neutral may feel pressure to encourage settlement if she later disagrees with her own written award.
- Parties still experience settlement pressure due to the pending binding decision.
Med-Arb vs. Arb-Med: Key Differences
| Feature | Med-Arb | Arb-Med |
| Sequence | Mediation → Arbitration | Arbitration → Mediation |
| Confidentiality concern | Yes (if same neutral) | Reduced |
| Settlement pressure | Yes | Yes |
| Award flexibility | Flexible until arbitration | Fixed before mediation |
When Is Med-Arb a Good Choice?
Med-arb is particularly appropriate when:
- Parties need guaranteed resolution.
- Time constraints are severe.
- Business continuity depends on settlement.
- The dispute involves repeat players who want to preserve relationships.
However, in many disputes, straightforward mediation or arbitration alone may be sufficient.
The Bottom Line on Med-Arb and Arb-Med
Hybrid ADR processes like med-arb and arb-med can resolve disputes efficiently and definitively.
But they require careful consideration.
Before agreeing to med-arb, ask:
- Am I comfortable with the mediator becoming the arbitrator?
- How will confidential information be handled?
- Do we need one neutral or two?
- Is speed more important than flexibility?
Med-arb has proven effective in many commercial and labor disputes. Yet like all dispute resolution mechanisms, it is a tool—not a cure-all.
Choosing the right process is often as important as resolving the dispute itself.
Have you ever used med-arb or arb-med? Did the hybrid structure help—or create additional pressure?

I find arb -med to be more effective. I seal a potential result after hearing the parties cases. Then we mediate. If there is no agreement, I open the arbitration result. That sealed envelope is a powerful incentive for the parties to settle the case. Also, the retain their confidential information until the mediation.
Good and informative article which covers basically the essentials the disputants and perhaps neutrals need to know about Med-Arb and Arb-Med processes. I wonder whether an unsatisfactory party can challenge the award on for example, ground of misconduct of the Arbitrator or on any other grounds as he may have reason to challenge the award. I find it interesting to know that in either of the two mechanisms, the outcome is an award given by the Arbitrator unless of course, the Med-Arb did not end up in impasse to move to the Arb level, in other words, parties were able to settle their dispute and draw up their Mediation Agreement without moving to Arbitration.
