Charlie Sheen will not be allowed to see his estranged twin sons until he submits to a psych exam, RadarOnline.com is exclusively reporting.
Sheen, 45, hasn't seen the twins since cops made him surrender them to soon-to-be ex-wife Brooke Mueller -- the emotional moments all caught on our cameras.
While the terms of Sheen and Mueller's custody agreement have remained confidential, RadarOnline.com has learned one clause -- which Sheen agreed to -- is that he have a full psychological evaluation.
"Charlie must submit to a mental health evaluation with a licensed professional before he can see Bob and Max," a source with knowledge of the situation said.
"Charlie won't see the boys until he sees a psychiatrist, that is someone neutral, that hasn't previously treated him."
The former Two and a Half Men star has not submitted for the test yet, RadarOnline.com has been told.
His camp did not return our request for comment.
Mueller, 33, has had primary custody of the boys since a court issued a temporary restraining order earlier this month; a court hearing for the TRO was scheduled for Tuesday morning but was taken off calendar.
We first reported how Mueller had demanded Sheen sit for the exam during the tense negotiations because she was "extremely concerned" for the safety of Bob and Max in their father's presense.
"Charlie knows what he has to do to see the boys," the source added.
"If he wants to see them, he will do it. Charlie agreed to these terms in the custody agreement. He has to adhere to the terms."
Added the insider: "The fact is though that before Charlie's problems began in the last several months, he had had little or no contact with Bob and Max in the previous 16 months."
