Do Not Rent a Storage Unit to Corbin Bernsen

Somebody get McKenzie, Brackman, Chaney and Kuzak on the phone -- Corbin Bernsen is being sued.

According to a lawsuit filed in L.A. Superior Court, Bernsen signed a lease on a storage unit in Van Nuys, Calif. back in April 2000 for $900/month. The storage company claims he vacated the unit on January 31, 2009, but hadn't paid rent since January 2004. Sum of unpaid rent -- $55,800.

Now get this -- the storage unit company claims Bernsen rented another storage unit in February 1999 for $860/month, which he vacated in February 2009. According to the company, Bernsen hadn't paid rent on that unit since January 2003. Sum of unpaid rent -- $66,600.

Corbin's people tell TMZ they have been in a long-standing dispute with the storage company. His camp feels they haven't held up certain aspects of the lease agreement.
