Jennifer Masche, whose children are the subject of WE's 'Raising Sextuplets,' filed for legal separation from her husband, Bryan, earlier this month after his arrest for domestic violence in Arizona. Masche is seeking sole custody of the couple's children.

According to court records, Masche filed the petition days after Bryan was arrested at her father's home in Cape Verde on Sept. 11 after the pair fought over where to take the children on a trip. In 911 calls, Jennifer's father made comments that hinted the couple was already nearing separation.
