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."
