Most domain registrars allow you to add "privacy protection" for a nominal fee, which basically replaces your name under the WHOIS registrant info with theirs instead of yours. While this effectively shields outsiders from discovering who you are, the registrar likely knows the information of the original buyer...

It probably can be handled by a lawyer and/or trust as well. Even if they get past the registrar privacy, they get some business entity or lawyer contact.
