Supreme Court of Georgia Rules You Cannot Use “Equitable Estoppel” to Force a Non-Signatory into Arbitration

For years, Georgia business owners and corporate lawyers have watched the steady expansion of arbitration. When a commercial dispute arises, the natural instinct for many plaintiffs is to drag every related entity into the room, signatory or not, under the banner of “intertwined claims” or “concerted misconduct.”

However, in Jackson v. Stevenson, S25G0922, 2026 Ga. LEXIS 146 (Ga., May 19, 2026), the Supreme Court of Georgia issued a stark reminder: arbitration is a matter of consent, not coercion. Writing for a unanimous Court, Justice Land made it clear that a signatory plaintiff cannot use the doctrine of equitable estoppel offensively to haul an unwilling non-signatory company into arbitration.

Here is what Georgia business owners and practitioners need to know about this major appellate course correction.

The Case Briefing: A Buy-Sell Deal Gone Sideways

The dispute arose out of a real estate development joint venture governed by two operating agreements. The “Jackson entities” owned 70%, while the “Stevenson entities” owned 30%. Both agreements contained standard arbitration clauses requiring any controversy to be resolved under the Federal Arbitration Act (FAA).

When the relationship fractured, the Jackson entities triggered a buy-sell provision. The Stevenson entities elected to buy out the Jackson entities for $7 million. However, before closing, a war of attrition broke out. The Stevenson entities demanded arbitration, alleging that the Jackson entities deliberately sabotaged the closing by piling artificial debt onto the venture and stripping away valuable real estate assets.

Crucially, the Stevenson entities discovered that one of the disputed real estate options was technically held by RICSHA, another company owned and controlled by Jackson, but one that was never a signatory to either operating agreement.

Over RICSHA’s vigorous and persistent objections, the arbitrator forced RICSHA into the proceedings, finding that the conspiracy claims were “inherently intertwined” with the rest of the case. The arbitrator ultimately hit RICSHA and the Jackson entities with a $3.75 million compensatory damages award. Both the trial court and the Court of Appeals affirmed the award, deferring heavily to the arbitrator’s authority.

The Supreme Court of Georgia stepped in and reversed.

The Court’s Core Legal Reasoning

The Supreme Court reversed the lower courts' rulings on two distinct fronts:

1. Courts Must Decide Arbitrability De Novo

The trial court had applied a deferential standard, refusing to “second-guess” the arbitrator's jurisdictional reach. The Supreme Court corrected this fundamental error. Because RICSHA never signed the contracts, it never agreed to let an arbitrator decide gateway questions of arbitrability. Trial courts must independently evaluate whether a non-signatory is bound as a matter of law, using a de novo standard.

2. Offensive “Equitable Estoppel” Does Not Apply to Non-Signatories

Equitable estoppel in arbitration is designed to prevent hypocrisy: it stops a signatory plaintiff from riding the coattails of a contract to claim legal benefits while trying to avoid the contract's arbitration clause.

The Stevenson entities tried to argue a “direct benefits” theory claiming RICSHA benefited from the agreement by allegedly interfering with it to retain the venture's property assets. The Supreme Court rejected this, clarifying that:

• A benefit must flow directly from the terms of the agreement itself, not from exploiting or interfering with a contractual relationship.

• Alleged corporate interference might make a company liable in tort, but it does not magically subject them to an arbitration clause they never signed.

• Georgia does not recognize an independent “inherently intertwined” theory of estoppel to force non-signatories into arbitration.

Key Takeaways for Georgia Business Owners & Lawyers

For Business Owners: Protect Your Asset-Holding Entities

It is incredibly common for business founders to use multiple LLCs. Some to operate a joint venture, and others to hold separate corporate assets (like RICSHA did here). This ruling reinforces the strength of the corporate veil. Just because you personally own two companies does not mean a contract signed by Company A can drag Company B into a costly private arbitration forum without your explicit consent.

For Litigators: Intertwined Claims Belong in Court, Not Before an Arbitrator

If you are representing a plaintiff in a commercial dispute and find that crucial assets or bad actors sit inside non-signatory parent companies or affiliates, do not attempt to force them into the arbitration clause. If you do, you risk getting an expensive final award completely vacated on appeal, wasting years of client time and money. The correct move is to arbitrate against the signatories and simultaneously litigate against the non-signatories in court.
