She had asked the court for the right to see her little girl, Michelle, who was just feet away from Dr. Daniel Malakov when he was shot in a park.
A judge denied that request Thursday.
Borukhova is accused of hiring her uncle to kill Malakov, who was killed last year.
The victim's family members says they are pleased the visitation request was denied.
The couple had been in the midst of a bitter custody dispute when a gunman shot Malakov in broad daylight on October 28. The attacker, using a makeshift silencer and wearing a black leather jacket and a dark hat, shot three rounds into Malakov's chest and vanished, police said.
Malakov had gone to the Queens playground to take his daughter to see his ex-wife.
