Mae gofyniad statudol ar awdurdodau lleol i ddarparu gwasanaethau eirioli annibynnol ar gyfer plant a phobl ifanc sy'n derbyn gofal, pobl sy'n gadael gofal a phlant mewn angen.  Rhaid i'r ddarpariaeth hon fod yn gwbl ganolog yn nhrefniadau awdurdodau lleol i ddiogelu a hyrwyddo lles plant. Yn ogystal â hynny, rhaid i awdurdodau lleol hefyd fod yn hyderus bod ansawdd y gwasanaethau sy'n cael eu darparu yn ddigon da er mwyn sicrhau bod y trefniadau diogelu yn effeithiol, a bod modd i blant a phobl ifanc gyrraedd at y gwasanaethau y maen nhw'n eu haeddu.
There are statutory requirements for local authorities to provide independent advocacy services for looked after children and young people, care leavers and children in need.  The provision of advocacy services must be absolutely central to the arrangements that local authorities operate to promote the well-being of children. Alongside that, local authorities must also assure themselves that the quality of the advocacy services provided is sufficient to ensure the effectiveness of safeguarding arrangements and that these vulnerable children and young people are able to access the services they deserve.
