Detective Superintendent Phil Owen of Greater Manchester Police said he is "very pleased" with the results of the Clare's Law scheme.
Speaking to Daybreak he said: "It's really important that we do learn those lessons.
"The domestic violence disclosure scheme I think is real evidence that we've listened to Clare's father, we've listened too various different organisations and from September last year we've given disclosure in over 50 cases."
Detective Superintendent Phil Owen from Greater Manchester Police's Public Protection Division has welcomed "any initiative that helps to protect victims of domestic abuse" to prevent further crime.
However, for an area as large and diverse as Greater Manchester we would have liked to have seen a greater take up either from those in a relationship or from friends, relatives or neighbours concerned about the possible risk posed to somebody they care about.
The Domestic Violence Disclosure Scheme (Clare's Law) is a preventative measure and enables potential victims to take control of their life and make an informed decision about whether to stay with somebody or not. It may be that somebody is in a relationship but isn't happy about some of the behaviour of their partner. If warning bells are ringing, then these are the types of people we want to hear from.
