Lawyers for Britney Spears and Kevin Federline are due in court Thursday morning after the pop star filed an emergency motion seeking expanded visitation rights with her sons, Sean Preston, 2, and Jayden James, 1.
Currently, she only has monitored visits roughly every other day, but cannot have the kids overnight. Spears is not required at the hearing, but she is expected to show.
As far as regaining 50-50 custody in the long run, her lawyer, Sorrell Trope, said her prospects are "good, based on the overall circumstances of the case."
Spears, 25, has been passing her court-ordered random drug tests, Trope added, and there's been "no complaints" with regard to her parenting coach.
However, Federline's lawyer told PEOPLE, "If progress is made, we're happy with that. But nothing so far has happened to alter Kevin's request to the court [for a permanent primary custody arrangement]. It's [only] been a week."
Last weekend, the pop singer was reunited with her mother Lynne, 56, and spent quality time with sister Jamie Lynn, 16. Spears and her mother had a falling out in June and had not been seen together.
Last month, Commissioner Gordon ruled that Spears is a "habitual, frequent and continuous" user of alcohol and controlled substances, and ordered her to undergo twice-weekly random testing.
Two weeks later, she was temporarily stripped of custody, and Federline retains physical custody of the boys for now. On Oct. 3, Spears was granted monitored visitation rights with her sons, and must complete a litany of orders by the next hearing date of Oct. 26.
The statement released by Kevin's attorney Mark Vincent Kaplan reads: "The fact that a party, one week after a full court hearing, attempts to change the orders of the court, in the absence of an emergency or without any new facts, suggests a continued lack of respect and understanding for what an order of the court actually means."
Kaplan also stated that K-Fed will not be in the hearing that will occur later today.
