Sia Plans to Testify at Upcoming Spousal Support and Custody Hearing

Sia‘s laid out the witnesses she plans to call at her upcoming spousal support and custody hearing … and she’s listed herself as chief among them.

According to a new filing, Sia says she expects to take the stand at a hearing for approximately 2 hours on issues such as spousal support, custody, visitation, attorney’s fees, and more.

Sia also lists her estranged husband, Daniel Bernad, who she expects her lawyers to cross-examine on various issues like custody … and accountant Tracy Katz, who she says will testify about child support and other financial issues.

As you know … Sia — who is being repped by disso queen Laura Wasser — and Daniel are going through a very messy divorce and custody battle over their son, Somersault.

Daniel claimed Sia’s debilitating drug problem posed a problem with parenting effectively … while Sia fired back by claiming Daniel had been investigated for child pornography.

A judge previously ruled most of the facts in Daniel’s filing were old news and shot down his emergency request for full custody of their son … and subsequently ordered them to go to mediation and try to hammer out a custody agreement.  And if that doesn’t work, it looks like they’ll hash things out in front of the judge.
