CROSSOVER: Trusts & The ‘Grandfather’ Clause: Why Fiduciary Ties Don’t Tolerate Indefinite Delays in Suing for Mismanaged Family Assets.

Conover v. Conover, 01-24-00471-CV, February 26, 2026.

On appeal from Probate Court No. 1, Harris County, Texas.

Synopsis

The First Court of Appeals affirmed a summary judgment holding that breach of fiduciary duty and fraud claims involving the alleged mismanagement of testamentary trusts were barred by the four-year statute of limitations. The court determined that while a fiduciary relationship existed, the discovery rule did not toll limitations because the beneficiaries had access to financial advisors and records years before filing suit, failing the “reasonable diligence” requirement as a matter of law.

Relevance to Family Law

For family law practitioners, Conover serves as a stark warning regarding the intersection of trust litigation and marital property characterization. In high-net-worth divorces involving “inherited” wealth or testamentary trusts, a spouse’s status as a beneficiary often leads to claims of mismanagement against family-member trustees (often a parent or sibling). This ruling clarifies that a beneficiary cannot rely solely on the fiduciary nature of the relationship to justify indefinite delays in investigating the trust’s corpus. If a client suspects their separate property interests are being diluted by a trustee’s self-dealing or failure to fund, they must act upon reaching the age of majority and obtaining access to financial accounts. Waiting until the trustee passes away to “look under the hood” will likely result in a take-nothing judgment under the statute of limitations.

Case Summary

Fact Summary

The dispute centers on the estate of William Van Conover, III (“Van”), who died in 2001, leaving two minor daughters, Rachel and Katie. Van’s father, Bill, served as the independent executor of the estate and trustee of testamentary trusts created for the daughters. Although Van’s estate was valued at over $4 million in 2001, the trusts were not formally funded until 2010—nine years after his death—and then only with approximately $619,000 each. Throughout their minority and into their early twenties, the daughters were told by their grandmother that Bill was mismanaging assets, but they initially disregarded these warnings because Bill paid their living and educational expenses.

By 2014, Rachel had direct access to a wealth management firm and could transfer funds from her trust to her personal accounts. Katie reached the age of 18 in 2015 and was similarly aware of her trust’s existence and value. It was not until Bill died in 2021 that the daughters, acting as successor trustees, investigated the original estate tax returns and discovered the $3.4 million discrepancy between the original estate value and the eventual trust funding. They sued Bill’s estate for breach of fiduciary duty and fraud. The trial court granted summary judgment for Bill’s estate based on the statute of limitations and an exculpatory clause in Van’s will.

Issues Decided

1. Whether the discovery rule or the doctrine of fraudulent concealment tolled the statute of limitations for claims involving a trustee’s failure to properly fund testamentary trusts.
2. Whether a beneficiary exercises “reasonable diligence” when they have access to financial advisors and portfolio reports but fail to reconcile those reports with the original source of the trust funding (the decedent’s estate).
3. Whether an exculpatory clause in a will protects an executor from liability for estate mismanagement absent evidence of willful misconduct or gross negligence.

Rules Applied

• Statutes of Limitations: Under Tex. Civ. Prac. & Rem. Code §§ 16.003(a) and 16.004(a)(5), claims for breach of fiduciary duty and fraud are subject to a four-year limitations period.
• The Discovery Rule in Fiduciary Contexts: While a fiduciary relationship generally relaxes the duty to inquire, it does not eliminate the requirement of “reasonable diligence.” As held in Berry v. Berry, a cause of action accrues when the injury occurs, and the discovery rule only defers accrual until the plaintiff knew, or in the exercise of reasonable diligence should have known, of the facts giving rise to the cause of action.
• Exculpatory Clauses: Under the Texas Trust Code and established case law, a settlor may limit a trustee’s or executor’s liability. To overcome such a clause, a plaintiff must raise a genuine issue of material fact regarding “willful misconduct” or “gross negligence.”

Application

The court’s analysis focused on the timeline of the beneficiaries’ knowledge. The court rejected the argument that the daughters could not have known of the injury until Bill’s death in 2021. The evidence showed that as early as 2010, the daughters were on notice that their trusts might be underfunded. More importantly, by 2014 and 2015, both daughters had reached the age of majority and were in direct communication with wealth management professionals regarding their trust assets.

The court reasoned that “reasonable diligence” required the beneficiaries to use the information available to them. Because they had the right to demand an accounting and had direct access to the professionals managing the money, the discrepancy between the $4 million estate and the $1.2 million combined trust funding was discoverable more than four years prior to the 2021 filing. Their failure to ask where the rest of the money went—despite warnings from other family members—was fatal to their claim. Regarding the exculpatory clause, the court found that the plaintiffs provided only “conclusory” allegations of misconduct, which failed to meet the high evidentiary threshold required to bypass the will’s protections for the executor.

Holding

The Court of Appeals held that the four-year statute of limitations barred the appellants’ claims for breach of fiduciary duty and fraud. The court determined that the cause of action accrued, at the latest, when the daughters reached majority and had access to financial advisors, as the alleged injury was discoverable through the exercise of reasonable diligence.

The court further held that the co-executors of the grandfather’s estate were protected by the exculpatory clause in the son’s will. Because the appellants failed to present more than a scintilla of evidence showing that the grandfather’s management of the estate rose to the level of gross negligence or willful misconduct, the clause precluded liability as a matter of law.

Practical Application

Texas family law litigators dealing with high-net-worth estates should apply Conover in the following ways:

• Interim Discovery: In a divorce, if a spouse is a beneficiary of a family trust, serve discovery on the trustee immediately. Do not wait for the final trial or a separate probate proceeding to determine if the trust was properly funded.
• Tolling Limitations: If representing a beneficiary spouse, document every request for information. If the trustee refuses to provide an accounting, this may support a fraudulent concealment argument, but Conover suggests that once the beneficiary has access to any financial advisor, the clock is likely ticking.
• Expert Reconciliation: Retain a forensic accountant to reconcile the “Inventory and Appraisement” of the original decedent’s estate with the current trust ledger. Conover proves that the court expects beneficiaries to perform this math once they are adults.

Checklists

Assessing the Discovery Rule Defense

• Identify the date the beneficiary reached the age of 18 (cessation of legal disability).
• Determine when the beneficiary first had contact with a financial advisor or wealth manager.
• Locate the first date the beneficiary received a portfolio report or account statement.
• Review all correspondence (emails/texts) for “warnings” from third parties or family members regarding mismanagement.
• Check for any “Authorization Forms” signed by the beneficiary allowing them to control or view trust funds.

Overcoming Exculpatory Clauses

• Review the specific language of the Will or Trust document to define the scope of the exculpation (e.g., does it exclude “gross negligence”?).
• Gather evidence of “Willful Misconduct”: Look for self-dealing, such as the trustee using trust assets to collateralize personal loans.
• Gather evidence of “Gross Negligence”: Look for a complete failure to fund the trust for an extended period (though Conover suggests even a 9-year delay might not be enough without more).
• Identify “Actual Intent” to defraud, as opposed to mere passive mismanagement.

Family Law Crossover

This ruling can be weaponized in Texas divorce litigation where a “waste of community assets” or “breach of fiduciary duty” is alleged between spouses regarding trust management. If one spouse is the trustee of a trust for the children or the other spouse, and the “injured” spouse has had access to tax returns or bank statements during the marriage but failed to complain, Conover provides a powerful limitations defense. It shifts the burden to the complaining spouse to explain why they did not exercise “reasonable diligence” during the marriage to investigate the financial discrepancies they now claim are “fraud on the community.” Essentially, in the eyes of the First Court, a fiduciary relationship is not a “get out of jail free” card for a party who ignores red flags.
