It reads to me like you are doing exactly the wrong things!
The deed attachment probably serves as notice of the adverse use time clock having a definite starting time--and once it times out you are dead meat.
The way I understand some of the case law elsewhere--once you become aware of the adverse use or should have been aware then there is no question of the time clock running against you.
Your post makes no sesne--if the home is on you lands --how do you accurately fence your lands?
Your survey is not accurate until som ecourt agres it is accurate--and you need to use a surveyor with considerable court experience--because you better get there!
In many places you rights as true land owner , once you prove you are the true land owner are superior--and that means you can require the other guy to move the house or tear it down back to the property line--and you need to focus on same--or his costs of doing so. If a $4 million dollar house sits on a $1,000 scrap of land--what is the true economic value of that scrap---its the avoided cost of moving or rebuilding the home!
