What Is an Arbitration or Mediation Clause in a Purchase Agreement?

Most real estate contracts include a section that decides how disputes will be resolved, typically offering mediation, arbitration, or court. Buyers and sellers usually skim past this section, but it determines what happens if the deal goes wrong: who pays, which forum decides, and whether either side can sue. In Pennsylvania, the standard Agreement of Sale and many brokerage agreements carry these clauses, and they are negotiable like everything else.

The two mechanisms are easy to confuse. Mediation is facilitated negotiation: a neutral mediator helps the parties talk and settle, but cannot impose a result. Arbitration is private judging: an arbitrator (or a panel) hears the dispute and issues a binding decision, which the parties agree in advance to accept instead of going to court.

Mediation starts with a neutral third party, the mediator, who leads the parties through their dispute: each side presents its case, the mediator explores settlement options, and the goal is a written agreement both sides sign. The mediator has no power to force a decision. If mediation fails, the dispute moves to the next step, arbitration or court, whichever the contract names.

Mediation is attractive because it is fast, confidential, and far cheaper than litigation. Real estate disputes, earnest money standoffs, repair arguments, and disclosure disagreements all settle well in mediation. The Pennsylvania real estate commission operates a mediation program for unresolved earnest money disputes, which is why many rejected deposit claims end up in mediation before anyone sees a courtroom.

Arbitration is a private trial: the parties present evidence and arguments to an arbitrator, who applies the rules and issues a binding decision. The arbitrator is usually an attorney or a retired judge chosen for expertise in real estate. The decision, called an award, is enforceable in court but is rarely appealable, which is the trade-off at the heart of every arbitration clause.

Compared with court, arbitration is faster and more private, but the parties pay for it, the discovery is more limited, and the decision is almost final. Buyers and sellers who sign an arbitration clause give up the right to a jury trial and to most appeals. That is exactly why consumer advocates warn about arbitration clauses in form contracts and why Pennsylvania courts scrutinize some arbitration agreements for fairness.

The Pennsylvania standard Agreement of Sale includes dispute resolution language, and mediation is commonly the first step, with arbitration or litigation following if mediation fails. Whether the contract compels binding arbitration depends on what the parties checked and initialed. Signature placement matters: in many forms, the dispute resolution section requires an initial or a separate signature to be effective, so a buyer who signed the contract without initialing that section may not have agreed to arbitration at all.

The same logic applies to the buyer agency and listing agreements, which often contain an arbitration clause of their own for commission disputes. An agent and client who disagree over a commission can end up in arbitration under the agency agreement, separate from the sale contract. Both documents deserve the same careful read.

Ask three questions before accepting a dispute clause. Is mediation required first? Is arbitration binding? And who pays the arbitrator's fees? A clause that requires mediation first is consumer-friendly. A clause that compels binding arbitration with the fees shared can still be reasonable; one that puts all costs on the homeowner is a red flag.

Clients can usually negotiate the dispute section: requesting non-binding arbitration, capping the arbitration costs, or insisting disputes go to court instead. Unrepresented buyers should treat the clause like any other term and have it explained before signing. If a dispute arises later, the first question your attorney will ask is what the dispute clause actually says.

Dispute resolution clauses decide where future fights happen. Set your expectations now.

• ✓ Mediation is negotiation: a mediator cannot force a result, only facilitate one
• ✓ Arbitration is private court: a binding decision replaces a jury trial and most appeals
• ✓ Check the initials: many form contracts require a separate initial to activate arbitration
• ✓ Ask who pays: arbitration fees shared between parties are reasonable, one-sided fee shifts are not
• ✓ Negotiate it: mediation-first and non-binding arbitration clauses are usually available

Read the dispute section in both the purchase agreement and your agency agreements, because commissions and contracts each carry their own clauses.
