You have a right to sue whenever you believe that you have been wronged.Unfortunately, that does not mean that a suit would be successful. One way to judge the likely success would be to consult with an atotorney and see if you can have the case litigated on a contingency basis. If there is much change of success you should be able to find an attoreny that is willing to work for a portion of the proceeds.
In this case, I doubt you will be able to find an attorney to take the csae on a contingency basis. The public records that still isted you as an owner during the time your ex did pay the taxes and the reliance on those public records is very likely enough to prove that the assessor and the credit agencies that relied on the public records did use due diligence and ordinary care and that they were not negligent and they had no intention to harm you when they used those records.
As you said, "I made a big mistake and didn''t sign a Quit Claim until 1993" Since that misinformation can be pointed to by those that granted you credit are not likely to be held responsible in a suit for damages.
I hope this helps; even though it is likely not what you wanted to hear.
