Under the Regulation, any EU country must automatically recognise judgements given in another EU country on parental responsibility matters.

A judgment on the exercise of parental responsibility enforceable in the EU country where it was issued can be enforced in another EU country when it has been declared enforceable there at the request of any interested party. However, no declaration is required for judgments granting rights of access or concerning the return of a child that have been certified by the original judge in accordance with the Regulation.
