If I have to discuss financial, legal or medical subjects (or anything requiring privacy, or anything really) via email, can I refuse to do so if I don't trust the domain of the email of the other party?
The country is Belgium if that matters.
More details about my specific case: my ex-wife and I have seen a notary¹ recently regarding our divorce. We need to come to a financial arrangement, so we have to discuss this via e-mail with the notary in CC. I have a Gmail email account, the notary has a belnot² account and my ex-wife has her employer's email.
I trust quite much @gmail.com because, ok, maybe their automatic systems will read my emails to target advertising, but no one malicious could ever specifically open my email about my divorce to... to what? What could anyone from Google do with that?
I trust @belnot.be quite much too, just because I've seen so many notaries with such an email account. That may be a bad reason but if so many professionals use this service, and those profesionals deal with sensitive data, I hope it's not too bad privacy-wise.
But I don't trust @my-ex-wife-s-company.be. Her new husband work there too, it's a small company (it's not a company but a public administration but it is small and managed without a lot of financial means and not too many rules) and I don't really know who can access the mailboxes of everyone.
I'm sure that I would not send emails from my company email for personal information, but can I refuse to send emails to a recipient I don't trust?
¹ Not sure about the translation, it is a notaire in French.
² I'm not absolutely sure about who manages this domain (maybe something like the national federation of notaries if such thing exists, or something equivalent), but most notaries in Belgium have a @belnot.be email account.
