You'll need to apply for an EEA family permit. You'll need a copy of your marriage certificate, not your
livret de famille. You can obtain a multilingual version of your marriage certificate (
Formule B) from the
mairie where you married for free or a nominal fee (it might be worth getting two or three copies to file away for future use). If your husband has been working in the UK for more than three months you'll also need to provide evidence of his employment when you apply. Once you arrive in the UK you should immediately apply for your
EEA residence card. This is 'optional' but you'll find it difficult to travel in and out of the UK freely without it once your EEA family permit expires (they are valid for six months). The application for your EEA residence card can take up to six months to process during which time you will be without your passport so make sure to take photocopies of both your bio-data page and EEA family permit.
