Inter/National Dues for sororities?

[AOE-7]

Does anybody know if there is somewhere that you can verify the national dues for organizations on your campus? I'm on a campus where it's really important that each organization disclose accurate financial info. Needless to say, we recently discovered that one organization is not being truthful with their financial obligations for recruitment. For Example: Most orgs list their total first semester costs in the mid $400s, but one org lists their costs in the low $300s. We've since then learned that the $300 does not include their inter/national annual/semi annual dues, or one time pledging and initiation fees, which is misleading to the PNMs.

I understand that many chapters do things differently - they may charge one lump sum, and pay those pledging, initiation and annual dues from the lump sum...but in at least one instance, we dont believe this is the case.

Does your campus require full financial disclosure? If so, how do you get cooperation from all orgs? Some chapters are all inclusive, some chapters fine, and other chapters assess left and right. At our campus, it's imperative that PNMs understand the minimum financial obligations, which includes Chapter dues, national dues, pledging and initiation, and any other fees that chapter regularly requires (corporation note, or housing obligations, if any...).

I tried to do a google search for this org, and I based on other campus websites and financial info, and even copies of bylaws I've found (hello, bright idea putting your orgs bylaws on the internet...), I think I have a good idea what their national obligations probably are. However, I'm not 100% certain. Any ideas?
