A court commissioner on Monday extended the control of Britney Spears’s father over the singer’s affairs, including her $40 million fortune.

Jamie Spears will remain co-conservator of his daughter’s estate until Feb. 14, the commissioner ruled, despite a lawyer’s claims Britney had a “strong desire” against her father’s temporary oversight.

The decision came in a hearing in which attorney Adam Streisand, who asserted he was hired by Britney Spears, argued that Jaime Spears’s conservatorship “would only cause further distress, agitation and estrangement.”

In addition, Streisand argued that co-temporary conservator Andrew Wallet “simply doesn’t have the knowledge” to manage Spears’s vast estate, he said in court. It was Streisand who valued the estate at $40 million.

Streisand, who’s reportedly related to the singer of the same name, instead suggested that Northern Trust Bank be named as the temporary guardian of her wealth.

But the court ruled that Jaime Spears and Wallet would remain as co-conservators, a court spokesman said.

The lawyers for Jaime Spears began with an opening statement asserting that he has no interest in taking her wealth, but rather watching over it until his daughter recovers, with the eventual hope she’s reunited with her children.

Wallet vehemently argued that the court be shown proof that Britney Spears was of sound mind to hire Streisand.

A court-appointed lawyer for Britney Spears was also present, and testified that he met with the singer at the hospital Sunday for about 10 minutes.

He added that in his opinion, the pop star “does not understand the nature of these proceedings” or their impact on her future. He added, “I think she lacks capacity” to hire a private lawyer.

It was also revealed by Jaime Spears’s attorneys that despite a restraining order issued Friday, the singer’s pal Sam Lutfi had “spoken to Ms. Spears by telephone.”

The father’s lawyers expressed difficulty at subpoenaing Lutfi with the order, saying he would not answer the door when a person came to serve him recently.

The commissioner ordered Lutfi to have no contact, direct or indirect, by phone, email, text message or any other means with Lutfi, a court spokesman said.
