Removing a Partner From Corporation

[frickson]

I have an S-Corp in Minnesota. My partner has 20% of the stock, I have 80%. He doesn't have time to devote to the company.

1) What do I need to file with the state, fedgov, bank to get his name removed?
2) What's the procedure for him to surrender his shares?

Or would it be easier to dissolve the corporation and re-register (if that's even possible)?

Thanks!
