IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

FIRST APPELLATE DISTRICT

DIVISION FIVE

LINDA GARAVENTA COLVIS et al., Plaintiffs and Respondents, A172824 v. (Contra Costa County LOUISA BINSWANGER, as Trustee, Super. Ct. No. MSP15-02131) etc., Defendant; GARAVENTA ENTERPRISES, INC., Appellant.

Garaventa Enterprises, Inc. (Company) appeals from the probate court’s order finding the Company is not an “interested person” (Prob. Code, § 48)1 and therefore lacks standing to participate in currently pending proceedings in this trust litigation. We affirm.

1 All undesignated statutory references are to the Probate Code.

1 BACKGROUND We recite only the background facts necessary to our resolution of this appeal, and begin by quoting from one of our prior opinions in this highly contentious matter:2 “During their lifetimes, Silvio Garaventa, Sr., and Mary Garaventa established the Garaventa Family Marital Trust (Trust). Silvio, Sr., died in 1998 and Mary restated the Trust in 2013, before her death in 2015. One of their five children, . . . Louisa, is the sole successor trustee under the terms of the Trust (Trustee). Their other children are Silvio, Jr., . . . Marie, Joseph, and Linda. [¶] The Trust provides that after Mary’s death, the Trust assets shall be distributed equally to five subtrusts, each benefitting one of the five siblings as an income beneficiary, with the remainder going to that sibling’s children. The Trust’s largest asset is a 70 percent ownership interest in [the Company]. Ownership of the remaining 30 percent of the Company is split equally among the five siblings, who each also sit on the Company’s board of directors.” (Binswanger v. Colvis (Oct. 29, 2025, A172554) [nonpub. opn.], fns. omitted.) In addition to the Trust holding a supermajority ownership interest in the Company, it also is in debt to the Company for loans made to the Trust. (Ibid.) The Trust estate has not yet been distributed to the subtrusts. Louisa, as Trustee, has exercised her control over the Trust’s supermajority ownership interest in the Company to take or decline to take certain actions involving the Company. (See Binswanger v. Colvis, supra, A172554.) This has generated a substantial amount of controversy—and litigation—among

members by their first names. No disrespect is intended.

2 the siblings. (See Garaventa v. Mangini (Aug. 23, 2024, A164692) [nonpub. opn.].) In 2022, Linda and Joseph filed a petition seeking an order instructing Louisa as Trustee to either apply for a loan on behalf of the Company to repay an estate tax debt owed by the Trust, or to borrow funds from the Company to satisfy that debt. The Company filed a brief seeking standing as an interested person under section 48. The court held section 48 did not apply to trust proceedings, and this court subsequently reversed and remanded “for the probate court to determine whether the Company is an ‘interested person’ pursuant to section 48.” (Colvis v. Binswanger (2023) 96 Cal.App.5th 393, 399.) On remand, the Company filed a brief seeking standing with respect to “[a]ll [p]ending [p]leadings.” Linda and Joseph filed a brief in opposition, and Marie joined in their opposition.3 In a written order, the probate court found the Company was not an interested person under section 48. The probate court noted that, although the Company was a creditor of the Trust, the pending claims were “breach of fiduciary duty claims,” including “allegations that Louisa delayed in making distribution of Trust assets to the Trust beneficiaries, that Louisa improperly used her power as majority shareholder of [the Company] prior to distribution to ‘pack the board’ with directors that are loyal to her, and generally damaged the interests of the claimant beneficiaries.” The probate court reasoned, “ ‘[T]he trustee of a trust does not owe any fiduciary duties to creditors of a trust’ ” and “the issues before this court are the exercise of Louisa’s fiduciary duties as trustee of the trust, not the rights vis a vis the Trust and one of its creditors. The claims in litigation

appeal.

3 between Louisa and the remaining Garaventa Children in this matter do not in any way affect [the Company’s] creditor rights, nor is there any provision in the Probate Code that authorizes [the Company] to assert claims as a creditor when it comes to decisions on whether a trustee has breached her duties to the Trust beneficiaries.” The court noted that “nothing in this Order is intended to prevent Louisa (or any other party) from calling [the Company] or any of its officers, directors, employees or anyone else affiliated with it as a witness in connection with the adjudication of issues related to claims of breaches of fiduciary duty by Louisa.” DISCUSSION Section 48, subdivision (a) provides, “Subject to subdivision (b), ‘interested person’ includes any of the following: [¶] (1) An heir, devisee, child, spouse, creditor, beneficiary, and any other person having a property right in or claim against a trust estate or the estate of a decedent which may be affected by the proceeding.” Subdivision (b) provides, “The meaning of ‘interested person’ as it relates to particular persons may vary from time to time and shall be determined according to the particular purposes of, and matter involved in, any proceeding.” “ ‘The probate court has flexibility in determining whether to permit a party to participate as an interested party. [Citations.] . . . “Subdivision (a) of section 48 does not purport to provide an exclusive list of recognizable interests. Rather, it permits the court to designate as an interested person anyone having an interest in an estate which may be affected by a probate proceeding. Subdivision (b) allows the court to determine the sufficiency of that party’s interest for the purposes of each proceeding conducted. Thus, a party may qualify as an interested person entitled to participate for purposes of one proceeding but not for another.” ’ ” (Colvis v. Binswanger, supra, 96

4 Cal.App.5th at pp. 398–399, fn. omitted, quoting Estate of Sobol (2014) 225 Cal.App.4th 771, 782.) “[S]ection 48 is designed to provide the probate court with flexibility to control its proceedings to both further the best interests of the estate and to protect the rights of interested persons to those proceedings.” (Estate of Maniscalco (1992) 9 Cal.App.4th 520, 524.) “Because the determination of whether a party is an interested person pursuant to Probate Code section 48 is subject to the probate court’s discretion, we apply the deferential abuse of discretion standard in reviewing the determination.” (Estate of Prindle (2009) 173 Cal.App.4th 119, 126.) It is undisputed that the Company is a creditor of the Trust and therefore has “a property right in or claim against” the Trust. To the extent the Company argues that its status as a creditor is alone sufficient to confer standing under section 48, subdivision (a), we disagree. The property right or claim must also be one that “may be affected by the proceeding” at hand. (§ 48, subd. (a)(1); see Lickter v. Lickter (2010) 189 Cal.App.4th 712, 728 [the closing phrase of § 48, subd.
