Late Fee Terms After 1yr Lease Expires

[Arnie Guida]

I've been told that my long held beliefs are not true. I've always thought that at the end of a 1 year residential lease, that it automatically becomes a month to month lease with the same terms, such as in late fees. I've been told that I can no longer charge late fees unless there is a new lease agreement.

Is this true? I guess I need to check Wisconsin State law...

Thank you, 

Arnie
