You have to study the principles of contract law and have enough braincells to see your defense from those principles (which I'm sure you do) and perform that defense in court.

Or you have to understand bills as negotiable instruments, namely UCC article 3 (codified in FL statutes too, just google it) and know how to perform on the bill with an indorsement and negotiate it by mail to the county  

Ideally both. You can win the foreclosure lawsuit easily if you stand your ground on these facts of law. 

 So I’ve seen a few TikTok vids on paying credit cards, buying cars, and paying utility/services bills by endorsing the “coupon” to have it paid via our cesti vie trust (if I recall how it was explained)

Also a vid about endorsing estimated income tax payments and getting a return on the 1040 (there is another form too involved but I don’t recall)

I just struggle to connect all the dots as well as identify the process from a reliable source other than Joe in his mom’s basement 

 Yeah you really want to find the time to watch Brandon's Contract Killer 2.0 course. It is free. That would "connect the dots" better than anything else. Don't bother asking attorney-at-law because they don't have a fucking clue, or they wouldn't be working for a paycheck.

Taxes are braindead easy to pay with indorsed bills and/or a revocation of election. Again, you have to watch brandons videos if you want to understand.
