A mother-of-one had secured a court order banning her suspected killer from contacting her just weeks before she was murdered.
The Northern Ireland Court Service said a non-molestation order had been made against Concepta Leonard's violent ex-partner Peadar Phair on March 21.
An application to extend the domestic violence order was due to be made in Enniskillen courthouse on Tuesday.
Ms Leonard, 51, was found dead in her home in Maguiresbridge, County Fermanagh, on Monday in an apparent murder-suicide. She is believed to have been stabbed by Phair, who had a history of violence.
Phair's body was also found at the scene in Abbey Road.
Her son Conor, who is aged in his 30s, was found with stab wounds to his stomach.
Ms Leonard had been concerned for her safety and the safety of her son and had applied for the injunction against Phair.
Non-molestation orders are civil court orders which aim to protect victims of domestic violence from being abused and to stop the abuser from being violent or intimidating towards the victim.
Family priest Fr Lawrence Dawson said Conor, who is in a stable condition in hospital, wants to carry his mother's coffin at her funeral.
Police are treating the attack on Conor as attempted murder.
They are not looking for anyone else in connection with the incident.
Ms Leonard ran a catering business in Lisnaskea and was a well-known musician in the local area.
