Hi Clicker,
I think all the DWP DLA resources are listed on the main DLA page in the members area.
I certainly don't recall a DBD385 and I can't find one using our search facility.
But if this is refered to in your appeal papersthen ask the DWP to provide you with a copy. You could also contact the clerk to the tribunal and ask that a judge issue a direction for the form to be included in the bundle.
Good luck with the appeal,
Steve
