¶1 The law firm of Dorsey & Whitney LLP (Dorsey) appeals the conservatorship court’s orders denying its motions to intervene in Jack J. Grynberg’s conservatorship case and to set aside an order entered in that case. We affirm the orders and remand the case to the conservatorship court to determine the reasonable amount of attorney fees incurred on appeal by the appellee, Marcie R. McMinimee (as conservator for Jack J. Grynberg).1 I. Background

¶2 Grynberg was an engineer and businessman who owned and managed oil and gas businesses worth millions of dollars. He was involved in protracted litigation against his then wife, Celeste, and his children, Rachel, Stephen, and Miriam (the family litigation).2 That litigation gave birth to this conservatorship case and ultimately a malpractice case against Dorsey. Following Grynberg’s death in 2021, the conservatorship was closed and a probate case

was opened. Understanding and resolving the issues Dorsey raises in this appeal requires some appreciation of this history, beginning with Grynberg’s estate plans.

A. The Estate Plans

¶3 Grynberg executed several iterations of his estate plan in the 2010s. His 2013 estate plan provided that, upon his death, his family members would receive significant ownership of his businesses. His 2013 estate plan also provided that Celeste would serve as his estate’s personal representative, with Rachel as an alternate.

¶4 Grynberg executed a new estate plan in 2014, in which he again designated Celeste as the personal representative but removed Rachel as the alternate and replaced her with a banker and professional trustee.

¶5 A few years later, and with the advice and assistance of Dorsey, Grynberg executed a 2018 estate plan, which removed Celeste as personal representative and disinherited two of his children — Rachel and Stephen. (As we will discuss below, the conservatorship court later invalidated the 2018 estate plan.)

B. The Family Litigation

¶6 By 2016, family members had become concerned about Grynberg’s cognitive health and its impact on the family’s interests in the businesses based on what the family claimed was uncharacteristic and erratic behavior. For example, Grynberg got caught up in various internet scams. Based on these concerns, these family members cut off Grynberg’s access to business bank accounts and reduced his titles and roles in the businesses.

¶7 In response to these actions, Grynberg sued family members in a Texas court, seeking to revoke their ownership interests and take back control of the businesses. The Texas court dismissed that case on forum non conveniens grounds. The family members, some family trusts, and two of the family’s companies then sued Grynberg in Arapahoe County District Court, seeking a declaratory judgment to confirm the family members’ ownership rights in the businesses. The plaintiffs also accused Grynberg of, among other things, breaches of his fiduciary duties, corporate waste, conversion, and civil theft. Grynberg countersued for, among other things, breach of contract, breach of familial fiduciary duty, and unjust enrichment. The family litigation lasted about three years.

Celeste and the children eventually prevailed in a jury trial and a separate trial to the court in 2019. Dorsey represented Grynberg during the family litigation.3

¶8 In 2017, while the family litigation was ongoing, Grynberg separately sought a dissolution of his fifty-eight-year marriage with Celeste. Dorsey also represented Grynberg in the dissolution of marriage case.

C. The Conservatorship and Probate Cases

¶9 In October 2019, Rachel, Stephen, and one of the family corporations petitioned for appointment of a special and permanent conservator for Grynberg in the Arapahoe County District Court. They alleged that Grynberg was suffering from “significant age- related cognitive disorders that impair his judgment and leave him vulnerable to a large number of individuals, including scam artists and lawyers and opportunistic employees — among others,” and they sought an order appointing McMinimee as Grynberg’s conservator. According to the petition, McMinimee was an

favor of the plaintiffs in the family litigation. Grynberg v. Grynberg, (Colo. App. No. 19CA1288, June 4, 2020) (not published pursuant to C.A.R. 35(e)).

experienced conservator and estate administrator. The court granted the petition and appointed McMinimee as Grynberg’s special conservator, finding her appointment “necessary to preserve and apply the property of [Grynberg] for the benefit of [Grynberg].” The court later appointed a guardian ad litem for Grynberg.

¶ 10 In March 2020, the conservatorship court ordered Grynberg to undergo a professional evaluation with Dr. Max Wachtel, a forensic and clinical psychologist. Shortly thereafter, Dorsey filed a motion (with a supporting affidavit) seeking unpaid attorney fees for work it had performed for Grynberg in or in connection with the family litigation.

¶ 11 After discussions with Grynberg and other individuals and reviewing relevant materials, Dr. Wachtel submitted his evaluation to the court in April 2021. He concluded that Grynberg lacked contractual capacity beginning in 2015 and continuing thereafter, was “highly susceptible to undue influence starting in 2015,” had diminished capacity to direct legal counsel starting in 2015, had no capacity to direct legal counsel starting in 2019, and wasn’t of sound mind when he executed the 2018 estate planning documents.

¶ 12 Based on Dr. Wachtel’s report, McMinimee filed a motion in May 2021 asking the conservatorship court to invalidate the 2018 estate plan. She also asked the court for permission to re-execute the 2013 estate plan. In that motion, McMinimee said that she had notified all interested persons as required by section 15-14-411, C.R.S. 2025. Although Dorsey had made a claim for payment of its fees charged in the family litigation, McMinimee hadn’t notified Dorsey.

¶ 13 The conservatorship court entered an order on June 9, 2021, invalidating Grynberg’s 2018 estate plan and authorizing McMinimee to revoke Grynberg’s 2018 estate plan and to re-execute Grynberg’s 2013 estate plan (the invalidation order). In the invalidation order, the court found that McMinimee had properly notified all interested persons.

¶ 14 Dorsey withdrew its request for fees on August 2, 2021, two months after the invalidation order.

¶ 15 Upon Grynberg’s death on October 11, 2021, the conservatorship was terminated by operation of law. § 15-14- 431(1), C.R.S. 2025. A probate case was then opened and the

probate court appointed McMinimee as the special administrator of Grynberg’s estate. The probate case apparently remains ongoing.
