I will recommend for you a fluent English-speaking notary working with international clients.
Often the buyer and the seller take different notaries in France who prepare then the sales agreement together.
If you wish to seek legal advice from your solicitor for reassurance, he can work together with your French notary, who is the only person authorised to set up a sale transactions in France, but it’s important to understand the vital role of the notary in France.
It’s also possible for both sides to employ the same notary for the deal if the buyer and the seller both agree.
If you can’t be present personally for the preliminary or (and) final contract, the notary will prepare a power of attorney and can sign on your behalf.
Since the pandemic in 2020 an electronic signature has been introduced in France for the purchase of the property in your absence.
It’s like an online meeting with your notary, who legalises your signature on the contract in an authentic way.
