Phillips, 43, filed for divorce on Monday in a Santa Barbara, California court, according to docs obtained by PEOPLE.

She cited "irreconcilable differences" as the reason for their split after nearly 12 years of marriage, though their separation date was listed as "TBD."

As per the documents, Phillips requested she receive spousal support and to "terminate the court's ability to grant support" to Masterson, with whom she shares 9-year-old daughter Fianna.

She also asked for full legal and physical custody of Fianna, and that their assets be divided up by the court as separate property, People reported.

"Ms. Phillips has decided to file for divorce from her husband during this unfortunate time. Her priority remains with her daughter," Phillips' lawyer Peter A. Lauzon told People in a statement.

He continues, "This period has been unimaginably hard on the marriage and the family. Mr. Masterson was always present for Ms. Phillips during her most difficult times of her life. Ms. Phillips acknowledges that Mr. Masterson is a wonderful father to their daughter. She hopes that everyone will respect her family's privacy in these difficult times."

Bijou reportedly attended  Masterson’s sentencing earlier this month.

Masterson was sentenced to serve 30 years in prison for raping two women

A source told PEOPLE last week that the actress was “distraught” over the sentencing.

The insider shared that Phillips is “surrounded by family and friends” amid her husband’s legal troubles, adding, “She is in touch with his lawyer. They are planning appeals. She tries to stay hopeful.”
