The `Blind Side` star`s lawyers obtained a document on 19.07.10 at a Los Angeles court to protect her from Thomas James Weldon, who has been "obsessed" with the actress since 2003.
Bullock first took out an order in California against the man seven years ago, but it expired in 2009.
Weldon voluntarily entered a mental institution in Tennessee but turned up to a Wyoming hospital last month, complaining of anxiety and sleeplessness.
While at the medical facility, he told staff he had driven from Tennessee hoping to meet the actress at her nearby home, admitted he had not been taking his medication and claimed he had been communicating with the 45-year-old star brunette beauty telepathically.
In a sworn declaration, psychiatrist Dr. Jiri Danczik wrote: "His preoccupation with Ms. Bullock is obvious."
Bullock-s attorney, Ed McPherson, filed a declaration stating the actress has received numerous emails and faxes in recent years from Weldon.
It is unclear when he was released from the mental institution, but in 2006, the Hollywood star sued the state to require they notify her of his release.
The order seeks to block Weldon from trying to contact the actress - and her seven-month-old son Louis Bardo - at any of her homes and movie sets.
A hearing to obtain a three-year order against Weldon has been scheduled for August 6.
