William Mumma, Petitioners v. Pedro N. Aguirre, Respondents

Summary

The Texas Supreme Court reversed the Court of Civil Appeals and affirmed the trial court’s award of custody of Estella Aguirre to the Mummas, holding that there was no material change of conditions and that the trial judge did not abuse his discretion. The Court emphasized the paramount importance of the child’s best interests and the presumption favoring natural parents, but allowed stability to outweigh that presumption in this case.
