Legal documents in English?

If you are referring to the French codes (the parliamentary acts that lay down the law in most areas of life), then Legifrance contains all of these in French, and some key ones are translated into English (for example, the Civil Code, which lays down rules on relations between private individuals, or the Commercial Code).

The site of Notaires de France also has a lot of useful information in English on French law in relation to matters like marriage or inheritance: www.notaires.fr
