As an HOA board member who works collecting delinquencies in small claims, I would suggest trying to settle for the amount owed directly to the HOA.
Maybe attend a meeting or ask to attend the delinquency section of the HOA board meeting.
Offering to settle is a better option than either paying or ignoring.
Another hoa where my client is buying just foreclosed on an owner who had not paid since buying.
If they insist on getting more, you can ask if they intend to spend another 1300 to collect another $45 bucks.
Another idea is to offer to keep the $1300 (or some portion thereof) as a subordinate lien (maybe with interest) that will be paid when you sell (whenever that is).
Also remind them about the cost that they incur every time they engage the atty services and that you always have the option of just not paying.
Good luck and try not to take the ostrich approach in the future.
