The measure approved on a voice vote Thursday would require the state to maintain and provide a system that allows district attorneys to manage and share domestic abuse case-related information.
It would also require the state Department of Justice to make a list of domestic abuse services organizations available to law enforcement agencies.
The Senate passed the bill earlier this week and it now goes to Gov. Scott Walker.
As originally introduced, the bill would have required police officers who respond to a domestic abuse call but don't arrest anyone to explain why. That was introduced in response to a mass shooting at a Brookfield spa in 2012.
