I have 2 unlawful detainers on my credit report and 1 is a judement. should i pay it off or let it be removed.

I DID CONTACT MY PREVIOUS LANLORDS LAWYER AND HE TOLD ME THE 2770 DOLLAR JUDGEMENT WENT UP TO 5,OOO AND THAT THE LANDLORD WOULD ACEPT 4,000. I DONT NOW IF THIS IS TRUE OR NOT. ALSO I CONTACTED A CREDIT AGENCY AND THEY TOLD ME THEY COULD GET THE UNLAWFUL DETAINER REMOVED. IS THAT TRUE? I JUST WOULD LIKE TO KNOW WHAT I SHOULD DO ABOUT GETTING IT TAKEN CARE OF
