Missy,
I don't know how it works in Texas, but here in Florida the HOA dues follows the property and not the owner. Thus when the condo sells in foreclosure, the title company would request an estoppel from the Homeowner's Association. Upon notification of the delinquent dues, this amount would be deducted from the closing proceeds.
The HOA can sue you yet they have no reason to. They will eventually get paid by the above procedure. If they do win a judgment against you they would be hard pressed to do anything other than placing a lien against the condo. Thus the HOA would be no better than before the suit!
Don't even worry about your credit rating getting damaged due to the civil suit. It doesn't even come close to comparing to the damage already done by your foreclosure.
To prevent the headache of a civil suit, you may wish to notify the HOA that they will eventually "automatically" receive the delinquent dues upon the foreclosure sale. Most homeowner Board Members do not realize this and simply think they MUST sue.
