Flo Rida's six-year-old son, Zohar Dillard, was rushed to an intensive care unit after suffering "serious injuries" when he fell from the window of a fifth-floor apartment.
The incident happened in New Jersey and left the youngster with fractures in his pelvis and left foot. He also suffered a lacerated liver, collapsed lungs and internal bleeding.
Zohar's mother Alexis Adams filed a civil lawsuit on Monday against the people she claims are responsible for the fall, which occurred on March 4.
The defendants include a construction company, a window installation company and the apartment's owners and managers.
Alexis claims the Jersey City building had been equipped with windows that "posed a hazardous condition," causing her son to fall "to the concrete pavement below."
According to legal documents obtained by TMZ, Flo Rida is not a plaintiff in the lawsuit.
Alexis is seeking damages, attorney's fees and payment of Zohar's medical bills.
In a statement, Alexis said she has been left "heartbroken" by the incident.
"As a single mom to a special needs child, this feels like a nightmare. My heart is broken into a million pieces.
"I am devastated, angry and struggling to come to terms with the fact that my only child has suffered severe injuries due to wilful negligence of our landlord and others involved In failing to take necessary safety measures," she told News12 New Jersey.
Flo Rida has not publicly addressed the accident.
Alexis previously revealed that the 43-year-old rapper, whose real name is Tramar Lacel Dillard, has had no involvement in her child's life.
"Flo Rida has only seen his son once during the paternity test [in December 2016] but kept his shades on and his back turned she told The Daily Mail in May 2018.
She added: "They were in the same room. He didn’t try to hug Zohar, nothing. It was very cold."
The current status of their relationship is unclear.
