In 2012, the Barnetts petitioned a court to change Natalia's birth year from 2003 to 1989, making her 20 years old when they adopted her and accused her of attempting to harm them on several different occasions.

Michael and Kristine subsequently moved with their three sons to Canada, leaving Natalia to live by herself in an apartment in Lafayette, Ind., the following year.

Six years later, Michael and Kristine—who finalized their divorce in 2018—were brought up on charges in connection to their move. Michael was found not guilty on his charges in 2022, while prosecutors dropped their case against his ex-wife this past March.

The latest installment of Natalia's twisted adoption story will take a closer look at the "saga and the Barnetts' allegations from Natalia's perspective," according to a press release from ID, "offering insight into what really went on behind closed doors in the Barnetts' home."

The three-night docuseries The Curious Case of Natalia Grace: Natalia Speaks kicks off Jan. 1 at 9/8c on ID.
