This company has never bought a website before, i've never sold one, and my lawyer is a "business" lawyer. he's no help regarding the finer details of what running a site is all about.

The perfect storm...

All of this should have been worked-out BEFORE agreeing to the sale, of course.

So, OK, water over the bridge. Work it out now. You just need to talk and determine what each others needs are.

If your GoDaddy account has no other domains in it, why NOT turn it over? It would make things easier for the buyer. If it has other domains, though, really not a problem, as it isn't normal to turn over the account. You allow them to transfer the domain registration to the registrar of their choice (or another GoDaddy account).

You need to provide them with the website content, and any associated software. You need to agree on how to turn this over to them.

It's important to insure the continuity of the website, so you may continue to operate it for a while until they work-out the technical details.

Email looks like a problem you will have to deal with. It was a mistake to mix business and personal email on the same address. If the email address is @ the domain associated with the site, I would notify your personal contacts immediately of your new personal address, and expect to turn over the address to them - they will have control over it in any case.

I actually had this issue with a domain that I sold. I just registered <firstname>@<firstname><lastname).com and notified everyone of my new address. I won't have that problem again. ;)

- GoDaddy will let you know exactly how to do this, Godaddy sells and parks domain names all the time.

- I don't think you can transfer the whole account, the terms of that account applied to you. I could be wrong but if I am then you will find an "account transfer" option somewhere on GoDaddy. I know they have a domain transfer process in place.

- re email. mixing business email with personal is always a no-no. I don't imagine you want personal emails ordered to be shown in court if something legal happens with the business down the road. Recent law changes require IT's to keep backups of ALL internal emails from ALL company workers personal or not... or possibly face charges should they not exist when they are requested).

That being said you can just delete the email and likely not have problems with the buyer re-creating the exact same email address UNLESS you used the "admin@" or "webmaster@" or other official addresses for personal use. Those i'm afraid belong to the domain BUYER, and not you, after the sale. Email addresses are tied to two things. The company and the domain name and usually the company owns the domain name.
