What are the legal nuances of selling a site?

Question

Law in IT

Hello. There is a portal with users, news, bulletin board, company directory and ratings. I want to sell it.
The question arises what are the legal subtleties? For example, what about users (personal data (mail, name))? If later, someone (companies or regulatory authorities) claims against the site, to whom will they be addressed? And other nuances that I do not know.
I would like to hear the opinion of those who sold similar projects.

Answer 1

Yes, there are no legal nuances there.
I handed over the domain, handed over the hosting - that's all, there is no more demand from you.
