Questions Presented

  1. Whether the Court of Chancery or the arbitrator had authority to decide whether Lafferty was bound by the Fifth LLC Agreement and its arbitration clause.
  2. Whether the Fifth LLC Agreement was validly adopted under the amendment provisions of the Fourth LLC Agreement.
  3. Whether Lafferty manifested assent to the Fifth LLC Agreement by signing the Equity Award Agreement and incorporated documents.
  4. Whether Lafferty manifested assent to the Fifth LLC Agreement by accepting benefits under it through his conduct.
  5. Whether Lafferty's reliance on an email describing the amendment as not materially adverse excused his failure to read the Fifth LLC Agreement.

Holdings

  1. Questions concerning contract formation and the existence of an agreement containing an arbitration clause are for the court to decide, even when the purported agreement includes a broad delegation clause.
  2. A party who signs an agreement that incorporates another agreement, including through nested incorporated documents, is bound by the incorporated agreement's terms, including its arbitration provision.
  3. A party that accepts the benefits of an agreement cannot later reject the agreement's burdens, including its dispute-resolution provision.
  4. The court need not decide whether the Fifth LLC Agreement's replacement of the Delaware forum clause materially, adversely, and disproportionately affected Lafferty because, even assuming his consent was required, the record established that he later consented.

Factual background

Lafferty became a member of Corient Partners and initially joined the Fourth LLC Agreement, which required litigation in Delaware and permitted amendments subject to limits on material, adverse, and disproportionate effects. Corient later adopted the Fifth LLC Agreement, replacing the Delaware forum clause with a broad arbitration provision. Lafferty electronically signed an Equity Award Agreement incorporating the Notice of Conversion, which referred to the Fifth LLC Agreement, and then accepted converted units, additional units, and quarterly distributions totaling more than $7 million in value before resigning. After his resignation, Corient initiated arbitration concerning restrictive-covenant claims.

Procedural history

Corient initiated a JAMS arbitration against Lafferty on December 29, 2025, and an emergency arbitrator issued a temporary restraining order after determining that Lafferty had expressly adopted the Fifth LLC Agreement and its arbitration clause. Lafferty filed this action on January 2, 2026, asserting that the Fourth LLC Agreement governed and required litigation in Delaware. The Court of Chancery held a paper-record trial and entered judgment for defendants, denying the requested injunction.
