In the three weeks since Britney Spears' powerful testimony in which she called her nearly 13-year conservatorship "abusive" and pleaded for the court-ordered arrangement to end, there have been multiple subsequent legal filings in the case and growing outcries of support for the singer.

Spears told Judge Brenda Penny at the hearing last month that she wanted to hire her own attorney to advocate on her behalf, stating that she had been forced by her conservators to perform, take lithium and remain on birth control against her will.

Her court-appointed attorney since the inception of her conservatorship in 2008, Samuel D. Ingham, subsequently submitted his resignation, as did the appointed co-conservator of her estimated US$60 million dollar estate, Bessemer Trust.

There is another hearing for Spears' conservatorship on Wednesday, during which Judge Penny is expected to consider the singer's request for new counsel, along with other petitions in the case.

Though Spears is not required to attend, it's anticipated she will call in by phone, as she did at the last hearing.

Here is a timeline of what's transpired since.

June 23, 2021

Britney Spears calls into a hearing at the Los Angeles County Superior Court to address Judge Brenda Penny regarding her conservatorship.

Audio from the hearing is live streamed, marking the first public comments from Spears about her conservatorship in nearly 13 years.

Spears speaks for more than 20 minutes and makes a series of explosive accusations.

"I felt drunk," Spears says of taking lithium against her will. "I couldn't even stick up for myself. I couldn't even have a conversation with my mom or dad about anything. I told them I was scared and they had six different nurses come to my home to monitor me while I was on this medication that I didn't want to be on to begin with."

She calls her conservatorship "abusive," comparing her treatment to sex-trafficking and criticizing her family and others involved in managing her day-to-day affairs and medical care.

"Ma'am, they should be in jail," Spears tells Judge Penny.
