As the first woman to serve as a full-time justice on the Supreme Court of Texas, Justice Ruby Sondock changed what generations of Texas lawyers and judges could imagine for themselves. She did more than reach milestones first. She transformed them into steppingstones for the women lawyers and judges who followed.

Born and raised in Houston, Justice Sondock did not set out to make history. She entered the University of Houston Law Center at a time when opportunities for women in the law were limited, initially hoping only to become “the best legal secretary in town.” Instead, she graduated as valedictorian of the Class of 1962, passed the bar before graduation, and argued before the Supreme Court of Texas during her first year of practice.

Her first job offer was made by Donn Fullenweider (a Family Law Section of the State Bar, Hall of Legends Honoree), who called her the day after she took the bar exam to request that she interview that day at the law office of Fred Parks. She was still completing course work for her law degree and couldn’t work full time or commit to a set schedule. Donn told her, “as long as you make a visible contribution to this office, I don’t care when you come or go.” That was an opportunity she could not pass up. She joined the law office of Fred Parks, working alongside Donn Fullenweider, where she practiced family law for twelve years.

While practicing family law, Justice Sondock noticed and then forcefully addressed the inequities facing women in their daily lives and particularly within the legal and court systems. She was a founder of the first Houston-based attorney association for women and was widely recognized for her contributions to women’s rights.

In 1973, Governor Preston Smith appointed Justice Sondock to serve as judge of Harris County Domestic Relations Court No. 5, the first woman in Harris County to hold a district level judgeship. Four years later, Governor Dolph Briscoe appointed her to the 234th District Court, the first woman to hold that distinction in Harris County. Then, in 1982, Governor Bill Clements appointed Justice Sondock to the Texas Supreme Court to fill the place of Judge James Denton who passed away suddenly. She became the first woman to serve as a full-time justice on the Supreme Court of Texas. During her tenure, she wrote a dissenting opinion in the well-known Vallone v. Vallone case addressing characterization and reimbursement claims in the divorce of famous Houston restauranter, Tony Vallone.

Though offered a nomination to serve as Chief Justice, Justice Sondock instead elected to return to Houston and serve in her former district court until her retirement in 1989. Following her judicial service, she became an of council attorney for the New York-based firm of Weil Gotshal and Manges. She completed her legal career as a mediator in her own Houston office.

Justice Sondock devoted much of her time and energy to improving the lives and careers of others. Generations of women remember her not only as a judicial first, but as a mentor who offered practical guidance, candor, and encouragement. She modeled how to command a courtroom with preparation and presence, and she helped younger lawyers see that they belonged in spaces where women had too often been underestimated.

In 2015, the State Bar of Texas proclaimed Justice Sondock a “Texas Legal Legend”. The University of Houston Law Center has established a lecture series named in her honor: the Ruby Kless Sondock Lecture in Legal Ethics. In 2026, the Supreme Court of Texas honored her 100th birthday by proclaiming April 26th as Justice Ruby Kless Sondock Day.

Justice Ruby Kless Sondock opened doors with courage and excellence, then helped others walk through them with confidence. Her story reminds us that the most enduring trailblazers do more than make history. They create a path for others to follow.
