In Lavizadeh v. Moghadam, a trustee purchased real estate and then had a dispute with a guarantor. No. 05-18-00955-CV, 2019 Tex. App. LEXIS 10835 (Tex.

During the hearing conducted prior to jury selection, the Trust’s counsel initially stated “for the record that we’re here on a jury trial setting” and he believed “factual issues [existed] that may need to be presented to the jury. . .”, however, he subsequently agreed to Moghadam’s counsel’s proposal to stipulate all exhibits into evidence. More specifically, the Trust agreed, “it would be appropriate” to have a “summary trial by the Judge on those issues, and then if we need a jury on a fact issue . . . “ the parties would return to court for further proceedings.
