Scott Wolf‘s request for a restraining order has been granted … and, for the time being, his estranged wife Kelley isn’t supposed to go anywhere near their kids.

The “Party of Five” star was granted the restraining order in Utah Wednesday afternoon … with the judge noting in his decision Kelley has “engaged in an escalating pattern of behavior that poses a substantial threat or immediate and irreparable harm” to the couple’s kids.

The judge awarded temporary sole physical and temporary sole legal custody of their three children … and, until further notice, Kelley “shall not have any parent-time or contact” with Scott or the kids.

As we reported … Scott filed for the restraining order Tuesday — including declarations from himself and Michael Wolf, who appears to be one of Scott’s siblings. The document is under seal.

ICYMI … Scott and Kelley announced they were divorcing earlier this month after two decades of marriage and three kids together.

Shortly after the announcement, Kelley was detained by police during a live stream … making shocking, yet unconfirmed, claims of abuse against Scott.

Kelley said Scott was “controlling” and “insane” during their divorce in a 911 call made just hours before she was cuffed, when she asked the police to help her get her belongings from the Park City, Utah home.
