Peers debated a committee report that calls for post-adoption support to be made a legal right, on 16 May 2013.
The Lords Committee on Adoption Legislation says local authorities and other service providers should be legally required to provide post-adoption support to children and adopters.
It says children adopted from care have often experienced neglect and abuse and may have behavioural problems which cannot be resolved "simply by being adopted".
Peers also discussed a second report by the committee, which expresses concern that new government measures designed to speed up adoption do not go far enough.
The committee, chaired by crossbench peer Baroness Butler-Sloss, was appointed to provide post-legislative scrutiny of the law on adoption, and to recommend changes.
There were 4,600 children waiting to be adopted in England in March 2012, according to official figures.
