How do you force an association to get you the required HOA docs?

Having been working on a short sale for months (representing the buyer on this one), we finally have approval from the Bank and now cannot get the association to give us the HOA docs.

This is a small self-managed association and they had big issues with the seller for nonpayment of dues (can't believe they did not foreclose the unit based on that alone, it was a huge amount owed). Having said that you would think they would be dying to get the buyer in so they could start collecting dues again. If this goes to foreclosure rather than short sale they will get nothing. The Bank is willing to pay some of what is owed.

I always thought associations were required by law to provide these docs. Any thoughts from you CA condo experts?
