Charities are being invited to bid for a share of £3.4m of government funding intended to help separated families work together for the sake of their children.
The Department for Work and Pensions said the funding was available for innovative projects as part of the second round of its £20m Innovation Fund.
The latest round will fund projects up to a maximum contract value of £750,000 each. The first £6.5m of the fund was allocated in April.
Funded projects in the first round included a national, internet-based ‘virtual’ mediation service hosted by the relationship support charity Relate.
Steve Webb, the work and pensions minister, said: "This represents a substantial increase in funding for out-of-court support for separated parents and is the biggest push to help fathers and mothers to collaborate to support their children – both financially and otherwise – that this country has ever seen.
"This is a chance for experts in the field to put forward innovative and effective ways of helping parents. We want to hear from as many organisations with interesting ideas as we can."
Bidding for the second round of funding closes on 17 June.
