What determines the legal address of the IP and is it possible to change the legal address in the Google seller account?

Question

Android

Hello!
You need a seller account in the Google console.
IP yet, I will register.
But the seller's account is needed urgently.
Therefore, a number of small questions both on the IP and on the account.
The information on IP says that as such, the IP does not have a legal address, and he can write there both the official place of registration and the actual location.
Now questions
For IP :
- The address of official registration, as I understand it, is the same as the Address of permanent registration? If the registration changes, how to change the official address of registration?
- In fact, in the line "Legal address" can I write either the address of registration or the place of my residence or the location of the office?
-In paragraphs like "Company Name" for the entrepreneur to write "IP Surname Name"?
According to the seller's account
As explained above, the legal address of an individual entrepreneur can change quite simply, so here's a question about the account.
- Is it possible to change the Legal information about the company, or rather the Legal address of the company, after linking the seller's account to the developer's console. Or will you have to create a new developer account and a new seller account?
