The Manzos and Lauritas are involved in a huge infringement suit by the owner of the "original" Black Water (now called BLK). It is alleged that Chris Laurita stole the idea and formula while acting as a marketing consultant for the product.
Albert Manzo was fired from his 80K state job for falsifying information. Now the state wants all of the money paid in salary to him returned. The Manzo boys are being sued (along with other cast members) for injuries they inflicted on two men in that huge barroom ball in the Caribbean.
The Lauritas are charged with bankruptcy fraud - basically for chanelling away all of the business's profits prior to filing for BK.
Of course, Juicy is facing prison time for fraudulently acquiring and using a driver's license (one he could use while his "real" license is under suspension), while both he and Teresa are defendants in the barroom brawl lawsuit.
You can Google all of the above for links and details. I imagine these are just the legal problems we are aware of.
ETA: I would add that there's speculation on the HW gossip sites that the Gorgas are living far above their means and may not be able to make a gigantic balloon payment coming due on their McMansion.
While not a legal issue, it seems that there is bad blood between Teresa and Caroline over their relationships with Dina. Caroline is reportedly "done" with Teresa because of this, not because Teresa is a sh*t stirrer with her Gorga brother and cousins.
I have to wonder why, with all this genuine drama going on in their lives, Bravo resorts to fake black eyes, Ashlee drama, and phone calls that never happened..
