The man reportedly sent the actress 'disturbing sexual emails' to her child's school and notes to her Goop store in Santa Monica.
Paltrow, who just got engaged to producer Brad Falchuk, filed the request on November 17 for protection from Justin Massler, who also goes by the name Cloud Starchaser.
The 35-year-old man has been known to stalk Paltrow, and other celebrities, including First Daughter Ivanka Trump, according to LAPD detectives.
In the restraining order, Paltrow has asked for protection for her children, Apple, 13, and Moses, 11.
In documents obtained by Radar, the 129-page restraining order declares: 'These actions have caused me to suffer substantial emotional distress, because I am worried that Mr. Massler may cause physical harm to me, my young children that live with me, my other friends and family members, my employees and anyone else that is associated with me and my family and may be confronted by Mr. Massler in his repeated attempts to get close to me.'
Judge Craig Karlan granted the request and ordered Massler to stay at least 200 yards away from Paltrow and her loved ones, according to the court documents.
In her declaration, Paltrow said she met with LAPD detectives on Nov. 15 and was told there is an open investigation on Massler, who allegedly has stalked and harassed others. Paltrow said the investigators told her Massler is in custody, but that he has the ability to make bail and could be released at any moment.
According to the Los Angeles County Sheriff’s Office, Massler was arrested and booked on Oct. 28 for a misdemeanor charge. He is still in jail as of Wednesday and is being held under $30,000 bail.
