A charity in Jersey says it has to raise £250,000 to continue providing services on the island next year.
Brighter Futures, which supports vulnerable families, says it has enough funding for 2010, but has nothing secured for 2011.
The charity says it has been relying on money from various trusts which come to an end this year.
Wendy Hurford, president of Brighter Futures, said: "We will raise the money, but it's an on-going battle."
She said: "The trustees are determined the charity will continue because we feel that the work we're doing for so many vulnerable families is important."
The charity which works with families to help improve parenting skills is currently using an £80,000 grant from social services, but is concerned it may have to stop taking on new clients.
Ms Hurford said: "We receive half a dozen referrals a week from a range of agencies like social services and schools. How can we turn around and say that we can't help these families when they're desperately looking for support?"
