The pop star’s lawyer asked an LA court to end Jamie Spears control of her estate, in November last year.
They said the star was “afraid of her father” and wanted him removed as her sole conservator – a role he has carried out since 2008.
Although the request has been denied, the ruling is not a response to Spears’ explosive testimony in court last week.
Speaking for 23 minutes, the star said she had been drugged, forced to perform against her will and prevented from having children
The star also said she had been denied the right to have more children and was put on the psychiatric drug lithium against her wishes.
Spears, a mother of two, said she wanted to marry her boyfriend and have another baby, but the conservatorship would not allow her to. She accused her conservator of stopping her from having a contraceptive intrauterine device (IUD) removed so she could get pregnant.
