Vanderpump Rules alum Brittany Cartwright is filing for full custody of her son amid her divorce from Jax Taylor.

On Tuesday, Aug. 27, nearly six months after Cartwright, 35, announced that she and Taylor, 45, were “taking time apart,” the Kentucky native filed for divorce and primary custody of their 3-year-old son Cruz, according to court documents obtained by PEOPLE.

The California files show that Cartwright requested legal and physical custody of their 3-year-old, but asked that the court grant Taylor visitation rights. Cartwright also asked the court to terminate spousal support to both parties.

The docs list the date of separation as Jan. 24 and cite “irreconcilable differences” as the reason for the divorce.

A rep for the couple had no comment when reached by PEOPLE.

Cartwright, who wed Taylor in June 2019, previously revealed on Feb. 29 that she and her spouse would be going their separate ways during an episode of their joint podcast, When Reality Hits.

“Many of you guys have been asking me about Jax and I and our relationship,” Cartwright said at the time. “I just think it’s important to be real and honest with you guys because our life is definitely — we’ve shared so much of our life with you guys. So, I feel like … I don’t want to seem like I’m lying or anything like that so I think it’s important for me to say this.”

“I know on my last podcast, I alluded to many marriages go through rocky times,” she added. “Yes, marriages in general are very hard and I’ve had a particularly rough year this past year. Jax and I are taking time apart and I made the decision to move into another home to take some space for the sake of my mental health.”

The mother and reality star also shared on the podcast that the breakup was “still very hard to talk about.”

“I’m taking one day at a time,” she said. “I don’t know what the future holds, but right now my focus is on being the best mom to Cruz.”

As per court docs, Cartwright has requested primary legal and physical custody over the couple’s three-year-old son but she is open to visitation for her ex. Additionally, Cartwright is seeking to block the ability of the court to award either one of them with spousal support
