How to Reality-Test an Unreasonable Proposal in Mediation Without Taking Sides

The proposal lands on the table with a thud you can feel in your own chest. He wants the house, the business, and full custody, offering her a token amount of the assets and every other weekend. The air in the room gets thin. Your client’s jaw is a single, tight line. You can see the words forming on their lips, the outrage, the accusations, the flat-out “no.” Your own mind is racing, searching for the right diplomatic phrase while a louder, simpler voice inside is screaming, “Are you serious?” You find yourself Googling “how to respond to an unreasonable offer in mediation” on your phone during a break, because even after years of doing this, a demand this disconnected from reality can still stop you cold.

What’s happening here isn’t just a negotiation tactic. It’s a communication trap that drags you, the neutral party, directly into the conflict. The proposal isn’t actually designed to be accepted; it’s designed to make a point. It’s a demand for a moral victory dressed up as a settlement offer. If you challenge it directly, you’ve taken a side. If you ignore it, you lose control of the process. You’re caught in a double bind: either attack the offer and become an adversary, or validate the offer and become an accomplice to a fantasy. The reason it feels impossible is because the move is designed to make your job impossible.

What’s Actually Going On Here

When a proposal is wildly out of sync with a likely outcome, it’s usually serving a different purpose than settlement. It’s an attempt to use the negotiation process to correct a perceived injustice from the past. The person making the demand isn’t trying to build a workable future; they’re trying to get a verdict on what already happened. Their offer isn’t about dividing assets, it’s about proving a point. You’ll hear it in their justification: “After everything she did, this is the least I deserve,” or “He needs to understand the damage he caused, and this is the only way to make him see it.”

This turns you from a mediator into a judge. They are looking to you to validate their sense of injury by taking their proposal seriously. The moment you start treating it as a legitimate starting point for negotiation, you’ve implicitly agreed with their version of history. But if you dismiss it, you are invalidating their pain and aligning with the other party. The proposal is bait, and the trap is that any direct response, positive or negative, makes you a participant in their drama rather than a facilitator of their agreement.

This pattern is kept in place by the very system they’re in. In an adversarial legal setting, parties are often coached to start with an extreme position. Friends and family, acting as a well-meaning but unhelpful chorus, tell them, “Don’t give an inch. You have to fight for what you’re owed.” They see the endpoint, winning, but have a massive blind spot for the cost of getting there. They don’t see the two years of legal fees, the stress that will make them sick, or the permanent damage to their co-parenting relationship. They only see the victory, and they expect you to help them achieve it.

What People Usually Try (and Why It Backfires)

Faced with this situation, most professionals default to a few logical-sounding moves. They almost never work.

• The Direct Challenge. You try to bring them back to earth with a dose of reality. You say something like, “A court is very unlikely to grant that.” This immediately positions you as an opponent. You’ve just told them they’re wrong. Their defenses go up, and now they have to fight you and the other party. The conversation becomes about proving you wrong instead of solving the problem.

• The Appeal to Empathy. You try to get them to see the proposal from the other side’s perspective. You ask, “If you were in their shoes, how would you react to this offer?” This backfires because, at this moment, they are fundamentally incapable of being in the other person’s shoes. Their sense of injury is so total that they believe the other person deserves to be shocked and dismayed. You’re asking for empathy from someone whose emotional tank is empty.

• The Process Punt. You avoid the bomb on the table by changing the subject. You say, “Okay, let’s set that aside for now and focus on some smaller things we might agree on.” While sometimes necessary to lower the temperature, this move doesn’t solve the core problem. The unreasonable demand is now the elephant in the room. It looms over every other part of the discussion, and the person who made it is just waiting for you to come back to it, building resentment the longer you wait.

A Different Position to Take

The way out is not to find a better technique for dismantling the proposal. It’s to adopt a completely different position in the room. Stop being the evaluator of the offer and become a curious, detached consultant on the workability of the offer. Your job is not to judge whether the proposal is good or bad, fair or unfair. Your job is to help the person making the proposal think through what it would actually take to make it a reality.

Let go of the need to manage their expectations. Let go of the responsibility for the outcome. Your sole responsibility is to the process. You are a thinking partner. You are not there to tell them their proposal is a fantasy; you are there to help them explore the hidden costs and practical steps of their own plan.

This shift is subtle but profound. You move from a position of judgment to one of inquiry. You stop reacting to the content of the offer and start asking questions about its implementation. You are no longer the person saying “no.” Instead, you are the person asking, “how?” This forces them to switch from defending their sense of justice to engaging the part of their brain that solves logistical problems.

Moves That Fit This Position

Your language should be neutral, inquisitive, and focused on logistics, not emotion or fairness. The following are not scripts, but illustrations of the kinds of questions that come from this new position.

• Explore the “How.” Instead of commenting on the proposal itself, ask about the path to achieving it.

  • “Help me understand the steps you see between where we are today and that outcome being finalised.”
  • This question is non-confrontational. You’re not saying it’s impossible. You are respectfully asking for their strategic plan. If they don’t have one, the question gently forces them to confront the gap between their desire and their reality.

• Test the Best-Case Scenario. Invite them to imagine life after they get exactly what they want.

  • “Let’s imagine for a moment you win on every single point. The judge grants you the house, the business, and custody. What does the day after that judgment look like? What new problems or tasks are on your plate?”
  • This moves them past the “win” and into the consequences. Will the other party comply? How will they manage the business alone? How will they tell the children? It connects the abstract victory to a concrete future they may not have considered.

• Quantify the Costs. Get specific about the non-financial price of the fight.

  • “Pursuing a goal like this requires a huge amount of resources. Beyond the legal fees, what do you anticipate the cost will be to your time, your focus at work, and your emotional energy over the next year or two?”
  • This reframes the cost. You aren’t telling them it’s expensive; you’re asking them to be the accountant of their own life-energy. It honours their agency while encouraging a pragmatic cost-benefit analysis.

• Outsource the Reality-Test. Make the objective system the “bad guy,” not you.

  • “What do you think a judge, who has only known you for a few hours and has a stack of 20 other cases to get through, would need to see as concrete evidence to grant this?”
  • This depersonalizes the obstacle. The barrier isn’t your opinion or the other side’s stubbornness; it’s the neutral, impersonal, and often frustrating standard of the legal system. You are now on their side, helping them figure out how to meet that standard.
