On Monday, Gordon's attorney filed a motion obtained by PEOPLE asking the court to stop the suit until the criminal investigation and any potential proceedings are complete.
The 24-year-old's papers say public interest in his girlfriend's death and her parents, the late Whitney Houston and Bobby Brown, has resulted in negative media attention that would make him "unfairly, legally and financially prejudiced should he be subject to parallel criminal and civil proceedings."
According to Gordon's papers, the wrongful death suit brought against him by Brown's court-appointed conservator alleges that he "is a murderer, a habitual batterer of women, a seducer of young white females, a thief and/or con-man fueled by monetary gain, and a chemist capable of making a toxic cocktail."
The filing claims any statements he makes in a civil case to fight the allegations may incriminate him in a criminal investigation or proceeding and that all evidence is not yet available. For example, Brown's autopsy report, which the Fulton County Medical Examiner has not released, "would be used to defend and lead to the dismissal of the allegations made against him in this civil proceeding," the papers say.
Gordon's development comes after PEOPLE learned that a grand jury has been convened to decide whether he will face charges related to Brown's death.
Gordon has denied allegations he gave Brown a "toxic cocktail rendering her unconscious and then put her face down in a tub of cold water." In September, his lawyers called the allegations "slanderous and meritless."
Brown died at the age of 22 on July 26, six months after she was found unresponsive in a bathtub at her home in Roswell, Georgia.
