Houston Texans' McNair Family Feud Erupts In Court

Sometime in late 2023, Cary McNair walked into Harris County Probate Court and tried to have his own mother declared incapacitated. That single filing cracked open the facade of one of Houston's wealthiest dynasties and set off a legal war that now threatens to swallow the family whole -- along with the NFL franchise they built from scratch.

The empire Bob built

The McNair fortune traces back to Robert "Bob" McNair, the family patriarch who founded Cogen Technologies in 1983 and turned it into the world's largest privately-owned cogeneration company. After cashing out of Cogen, Bob spread his chips across energy, real estate, and biotechnology through McNair Interests, his private investment firm. But the crown jewel came in 1999, when he brought the NFL back to Houston. The Houston Texans launched in 2002, and the McNair name became synonymous with Texas-sized ambition.

A son files against his mother

The family's fault lines broke into public view in late 2023. Bob McNair's son, Cary McNair, filed for guardianship of his mother, Janice McNair, in Harris County Probate Court. He cited concerns over Janice's health following a stroke and requested an independent medical evaluation. It looked like the opening salvo in a hostile takeover dressed up as filial concern.

Janice and Cary's brother, Cal McNair -- principal owner of the Texans -- fired back fast. They petitioned the court to seal the records, arguing that a public airing would damage the family's business interests, especially the Houston Texans. The court agreed. But sealing the file did nothing to stop the bleeding underneath.

Cary dropped the guardianship petition in February 2024 after a ruling denied his request for a medical evaluation. By then, it hardly mattered. The real fight had already begun.

Palmetto Trust drops the hammer

On June 5, 2024, Palmetto Trust Company (PTC) -- the entity responsible for managing the family's trust assets since its creation in 2010 -- filed a lawsuit in probate court that blew the doors off the McNair family's private affairs.

According to PTC's lawsuit, the trouble started after Bob McNair's death in 2018, when Cary assumed leadership of McNair Interests (MI), the family's private investment arm. PTC alleges that Cary's tenure was defined by excessive compensation for himself and key allies, including his son, Holt McNair, alongside poor investment performance and misuse of trust assets. The trust company contends that Cary's actions amounted to a broader attempt to seize control of the family enterprise.

The details in the filing read like a playbook for self-enrichment. PTC claims Cary concealed his actions from PTC's board by providing limited information while enriching himself and favored executives through a modified compensation plan that disproportionately benefited insiders. Meanwhile, McNair Interests' investment performance cratered. PTC attributes the decline directly to decisions made under Cary's leadership. Cary blamed the losses on "legacy investments" made during his father's era, but PTC argues the opposite -- that the further the company drifted from Bob McNair's guiding hand, the worse the returns got.

The guardianship gambit

PTC's lawsuit paints the guardianship petition as something far more calculated than brotherly worry. According to the filing, when PTC's board began questioning Cary's leadership in late 2023, he responded by filing the guardianship petition in November -- seeking to have his mother declared incapacitated and to install himself as her guardian. PTC alleges this was a strategic move to consolidate his power over the family's assets and shield himself from further scrutiny.

When that play fell apart, PTC claims Cary pivoted. The lawsuit alleges he created backdated employment agreements for himself and key executives, loaded with generous severance provisions designed to make them virtually untouchable. The terms were staggering: automatic contract renewals, guaranteed bonuses even in cases of poor performance, and legal protections in case of lawsuits over severance rights. A golden parachute stitched together in the middle of a family hurricane.

Brother against brother, sibling against sibling

The power struggle spilled further into the open as Cary filed additional lawsuits in Harris County District Court. On the other side, Cary's siblings -- Cal, Ruth, and Melissa -- are reportedly preparing to challenge his actions, fracturing what was once a unified family front. Both factions accuse the other of attempting to execute a "family coup" for control over the McNair business interests. Nobody is backing down.

What hangs in the balance

This is not just a family squabble with expensive lawyers. The McNair empire stretches far beyond NRG Stadium -- it encompasses a wide array of investments in real estate, energy, and biotechnology. As the litigation grinds on, it threatens to expose the inner mechanics of a multigenerational wealth machine and all the ugly friction that comes with it.

The outcome of these lawsuits could reshape the McNair legacy entirely, particularly as the family battles for control of the Houston Texans and the assets that underpin their fortune. Both sides have dug in. The stakes could not be higher. And the once-solid McNair family empire sits square in the crosshairs, with no resolution in sight.
