In court documents filed Friday in Los Angeles Superior Court and obtained by PEOPLE, the Modern Family star, 23, claims that Matt Prokop, 24, was verbally abusive, exhibited violent behavior, had lobbed multiple threats, and at one point, attempted to choke her.
According to the papers, Hyland claims that over the course of their five-year relationship, Prokop would call her a slew of derogatory names and hurl objects at her. The tipping point, she alleges, came in May 2014 when, during an argument, he purportedly slammed her into a vehicle and choked her.
In the court filing, which was first reported by TMZ, Hyland says she eventually sought the aid of Modern Family costar Julie Bowen, who intervened at Hyland's home in August 2014 to help her end the relationship.
The incident, Hyland claims, enraged Prokop, who later supposedly threatened the life of her dog and threatened to burn her house down. Hyland also alleges that he told a friend of hers that "I deserve to die."
Court documents state that after Prokop moved out of their home, in mid-August, he checked into a rehab facility. The actress claims that she secured the protective order at the urging of the facility's director, who purportedly warned her about Prokop's "mental state and attitude" as Prokop was set to be discharged on Sept. 21.
In a statement to PEOPLE, Hyland's attorney, Lee A. Sherman, said: "Out of respect for the court, the process and all parties, I have advised Ms. Hyland not to comment on the matter."
Hyland first met Prokop during an audition for High School Musical before the two costarred in the Disney TV movie Geek Charming. They dated from 2009 to 2014.
