How do you say solicitor or notary in French?

Avocat if you need an attorney, notaire if you need a French property lawyer (not to be confused with the US Notary Public).

In France, a lawyer or avocat (i.e. a French solicitor/attorney) is both a solicitor and a barrister as he or she can appear before courts of the first and second degree.

The Notaire is a public officer who drafts then records Deeds and contracts to which the parties wish to give a seal of authenticity, ensure their date, keep them in trust and to issue authentic copies of such documents.

A Notaire has a monopoly on conveyancing contracts or on establishing marriage contracts. Not to be confused with an anglo-saxon Notary who, as in the USA and the UK, mainly witnesses acknowledgements and oaths as an impartial party.
