I think that failure to pay HOA dues is charged against the property. Sooner or later, the HOA will try to foreclose at which time a mortgage holder is likely to foreclose if any payments are in arrears.

I agree with Mr. Lewis. However, in California, Wells has been extremely diligent in working with their clients in foreclosure so I suggest you contact them for assistance.
This is my opinion and should not be construed as legal advise for your specific case as there are many more facts which you have not provided.
Despite the fact that you notified Wells Fargo more than three years ago that you could no longer make the payments, you remained the owner of the home until Wells Fargo either foreclosed or accepted a deed in lieu of foreclosure or there was a short sale. Until then, you were/are the owner and therefore are on the hook for the HOA fees. Generally an HOA will file a lawsuit and then when they get a judgment, put a lien on the house. Here, if the house has already sold, they may or may not employ other approaches, such as garnishment, to collect the past due association fees. You may want to retain an attorney to negotiate a settlement of this debt.
