Victorian family violence victims will find it easier to get an intervention order against an attacker and to name and shame them.

Under laws that came into effect on Sunday, police can issue family violence intervention orders around the clock.

Previously, police could only issue those orders outside business hours, which forced victims to go to court at other times.

Attorney-General Robert Clark said it meant police could protect victims all day, every day.

"It makes no sense to say police can act on the spot to protect a victim if the victim needs help at eight o'clock on a weekday morning, yet the police can't act on the spot to help that victim if the violence occurs at nine o'clock on that same weekday morning," Mr Clark told reporters.
