Tommie Granville and Brad Troxel had two daughters together, Isabelle and Natalie. They never married. Their relationship ended in 1991. Brad lived with his parents, Jenifer and Gary Troxel, and regularly brought the girls there for weekend visits. In May 1993, Brad died by suicide. After his death, Granville continued to allow the Troxels to see the girls, but in October 1993 she told them she wanted to limit their visits to one short visit per month.
The Troxels did not want less time. They wanted more. They filed a petition in Washington Superior Court asking for two weekends of overnight visitation per month and two weeks each summer. Granville did not oppose visitation entirely. She offered one day per month, no overnight. The trial judge picked a middle ground that was much closer to what the Troxels wanted: one weekend per month, one week in summer, and four hours on each grandparent's birthday.
The legal question was not whether grandparent visitation is generally a good idea. It was about who decides. Washington's statute let any person petition for visitation at any time and authorized the court to order it whenever it was in the child's best interest. The trial judge had used that authority to override a fit mother's decision about her own children, based largely on his personal view that time with grandparents is good for kids. The Supreme Court was asked whether the Constitution allowed that.
