Initial discussions about what should be contained in a code of practice were held at a conference last month.
The meeting was called in response to the Children's Society's decision to withdraw support for Welsh projects earlier this year. The charity did not inform the Assembly or the Wales Council for Voluntary Action of its plans to withdraw, throwing the sector into disarray.
Discussions focused largely on the implications of devolution for existing decision-making practices and accountability in Wales.
Jane Hutt, health and social services minister for the Welsh Assembly, said: "The decision of the Children's Society and the way it was announced brought into stark reality what can happen if we do not work in partnership and talk to one another about problems and how they can be resolved.
