The government is expected to announce a pilot scheme which will allow women and men to go to the police and check if their partners have a history of domestic violence.
Michael Brown, whose daughter Clare Wood was killed in 2009 by her partner, told the Today programme that if his daughter had known about her partner's violent past she would have "dropped him like a hot brick and scarpered out of there".
"Domestic violence accounts for 16-20% of crime in the UK", he said.
But Sandra Horley, chief executive of the domestic violence charity Refuge, says they are "at a loss at to why the government is spending precious time and money on this scheme", known as Clare's Law.
She told the Today programme's Evan Davis that "the police already have the power to disclose [a history of domestic violence] and they aren't doing it".
She went on to say that it is "highly unlikely" Clare was killed because she wasn't informed of her partners past by police but rather that they did not respond quickly enough to her 999 call.
The scheme is extremely costly and police need to "get the basics right" rather than changing the a law, she said.
