The Michael Jackson estate just laid the smack down on a bunch of Michael Jackson wannabes -- all over access to Neverland.

The wannabes are actually in a Michael Jackson tribute band named "Neverland" -- a name the MJ estate feels is a violation of its trademark.

Long story short -- the MJ estate wrote a scary legal letter demanding the band change its name ... and it did ... to Foreverland.

Here's the catch -- "Foreverland" still owns the rights to the domain name neverlandsf.com -- and its willing to give it back to Camp Jackson ... for a cool $30,000.

In short, the Jackson estate told the band to "beat it" -- and gave them until February 2011 to begin forwarding all web traffic to the new foreverlandsf.com ... or else.

The band tells us they're currently going over their options.


"Lawyers from the Jackson estate have forced us to change our name."
