Parents who have split up will have to pay the Government "4p in the pound" if they need to use the new Child Maintenance Service (CMS) because they cannot be civil enough to come to informal arrangement themselves, the minister for pensions said.
Steve Webb assured Good Morning Britain the new system was "much more effective" than the previous Child Support Agency.
"If the Dad for example, gets a pay rise, we automatically go to tax records, update the figures so maintenance will go up every year there is a pay rise. That will help parents with children."
