I'm in the process of selling my flat and originally I agreed that the buyer and I would use just one notaire - nominated by them (as it turned out, their family notaire).   Half way through the transaction, both of us having signed the promesse de vente I now find that this was a mistake on my part and I want to appoint an additional notaire to bat for me.  Is this possible at this stage of the proceedings?  Salut, and reply soonest!   Boswell.
