Hi all. We have recently moved to Brittany and have eventually received a certificate from the Child Benefit Office in the UK, stating that we are no longer eligible for child benefit for our Son. Does anyone know what we're supposed to do with it now? My wife has just discovered that she's pregnant again, and we are waiting to fill in a form for Child Benefit for this baby too. But it appears we need our French child benefit number to put on the form. Can anyone help?
