Carter has had a tumultuous relationship with his siblings over the years, and many of their feuds have played out on social media, for the public to read. In September 2019, Carter made allegations of sexual abuse against his deceased sister Leslie, who died of a drug overdose in 2012, saying that the abuse lasted three years, beginning when he was 10 and ending when he was 13, and occurred when Leslie would fail to take her prescribed medication to treat her bipolar disorder. He also accused his brother Nick of lifelong abuse, though he did not go into details, and implied that Nick had abused a female family member. Nick's legal team denied the allegations, which came after Nick and their sister, Angel, sought restraining orders against Carter, who reportedly confessed that he had thoughts of killing Nick's then-pregnant wife, Lauren Carter.
