The order expires Friday. It requires Lutfi to stay 250 yards away from Spears and her home.
Wexler asked for the order to be extended until the court can schedule a hearing on it.
On Feb. 7, Spears' mother, Lynne, requested the temporary restraining order against the troubled singer's frequent companion and sometime manager. She claimed Lutfi had held Spears hostage in her own home, drugged her and took over her finances.
Attorneys for James Spears, who was named co-conservator of his daughter's estate, told a Superior Court commissioner that investigators spent more than 200 hours trying to locate Lutfi and serve him the restraining order.
Spears and her estate, estimated to be worth $100 million, were placed under a temporary conservatorship after she was taken to UCLA Medical Center on Jan. 31. Conservatorships are granted for people deemed unable to care for themselves or their affairs.
