The way to do it is to have your attorneys be the managers of your holding companies, then you can direct them (under privilege, afaik) to sign what you like. This is how I do it. Alternately if you have staff you trust and expect to have a long time (I don’t), they can be your holding company’s manager(s).
What is a "non-public" address? All addresses are public information. It is not at all clear what you're protecting and from whom; there is a distinct lack of a coherent threat model.
Everyone knows the address on your DL and vehicle registrations is basically public record, it’s sold to data brokers and is searchable. Same with any property held directly. This is why you have a holding company own the properties, and keep your name off the public records for the holding company.
Utilities might still be in your name, however, as not everyone knows how to obtain those under aliases or remembers to have their staff do it for them. They often want credit checks on a normal person for non-commercial service plans, or for residential addresses.
App location histories, mobile service location histories, Uber trip logs, food delivery order history, all of these are potential vectors for leakage, too.
There’s a big gap between “wealthy enough to be able to pay for some measure of privacy/safety for one’s family” and “wealthy enough to warrant spending salaries for three shifts of armed guards 24/7/365”.
Also, what do you think will happen if someone learns you live at a particular address? Literally what risk is there?
It’s not just data brokers who can search DL/vehicle data. It only costs a few bucks to access it. That’s their whole business model.
I know people who have been swatted, had their vehicles smashed, their children threatened, their houses shot up or vandalized or broken into, mail or packages stolen, et c. Fortunately I don’t personally know of any kidnappings or home invasions, but such an attack enables same for a sufficiently determined attacker.
People at risk like this either take steps to keep their residential addresses non-public, or hire 24/7 security forces, or both.
This is why my ISP account at the house where I sleep (as well as all other utilities and services for the address) is not in my name, and does not have my phone number or email address on it.
You’re just one data leak away from people from the internet being able to show up at your house in the middle of the night with guns (or outsourcing same to the police with a swatting).
I spend a lot of time and money protecting against this type of attack. It’s annoying. There should be real, actual, criminal liability for putting people at risk like this.
Maybe if someone publishes the excerpts from these with everyone with the same residential zip code and last name as all sitting US senators, something will happen. Then again, when weev did that (with just email addresses), instead of going after AT&T who leaked the PII through simple negligence, they prosecuted the guy who downloaded it and alerted the press.
It’s almost as if everyone not wealthy enough to have staff/managers/shell companies is just expected to not have any privacy.
