The Hills star on Monday obtained a temporary restraining order against her husband and on Wednesday filed for divorce, court records show.

"I am very concerned, especially since he has our daughter's birth certificate, that he might obtain a passport for her and take her to Australia without my consent," she stated in the documents.

She also cites an incident in which Bohan allegedly acted "very aggressive," arguing, following her around the house—all because I refused to tell him which person told me that he cheated on me with another woman."

"To be clear [the domestic violence restraining order] is not a strategic filing, it's very difficult for people to go public with these issues," Patridge's attorney Elizabeth Nigro told E!

They have not commented publicly about their split, which comes as a surprise as the family has appeared happy and united in Instagram photos as recently as August.
