A restraining order was slapped on Lutfi in February, after Spears's mother accused him of drugging Britney, 26.
Keep-away orders can be extended to up to five years, legal experts say.
Meanwhile, the singer's father and a lawyer remain in legal control over her affairs.
Their conservatorship will be reviewed by the court on July 31 – but it's expected their control will be extended.
Another hearing regarding Spears's estate is set for Thursday.
