Most or all case law, statutes, contract law, foreclosure courses, and foreclosure books adresses and ackowledges borrowers, judgment debtors, and successor-in-interest, so my question is:

How does one approach and be effective in a foreclosure in personam civil action case when you are the fee simple title owner to the subject property, but is not the borrower and/or judgment debtor?

The courts seen to just steamroll over anyone that is not the borrower and/or the judgment debtor to the mortgage and the promissory note.

How does one make sure the court acknowledges and respects the sole fee simple title oweners filings in the foreclosure in personam civil action case?
