Brit's Conservators Can Shut Down Sam

2/1/2008 7:46 PM PST
The conservators who were appointed to manage Britney's assets have broad authority, including changing the locks to her house and keeping out anyone they want -- we're guessin' that's Sam Lutfi.

The judge granted the conservators -- Jamie Spears and a lawyer co-conservators -- have the power to hire 24-hour security at her house, access her medical records and communicate with treating physicians.

They also have the power to make any decisions on her behalf, and can revoke any contracts she may have made recently -- which might include the new Mercedes she just bought.
