You have no legal grounds to dispute the monthly HOA dues regardless of other ongoing disputes. Do NOT subtract the amount from your monthly payment or your account will become delinquent and eventually sent to collections, where they could eventually foreclose on your home.

Unfortunately, in most cases, your HOA is a couple levels removed from the payment processor. Your HOA is required by law to have a licensed manager, so they outsource that to HOA management companies who employ these licensed managers.

Your HOA is most likely small and has no leverage with these HOA management companies. These companies exist solely to leech off HOA-related fees in exactly this fashion. They won't be changing their business model due to your complaint.

Now, you obviously have ways to avoid the fee such as paper checks and other inconveniences.

You might be able to recover past funds via small claims court with evidence of the inaccurate website.

But if you want to actually eliminate it, your only option is going to be to:

• Find another management company that does not charge the fee (these fees are pretty common in this industry though)
• Get other homeowners on your side and try to fire this current management company
