Yes, sadly, unless you can get law enforcement to intervene and remove squatters as trespassers, the law will accord them possession rights until the owner legally terminates those rights through an eviction case [[technically known as a summary possession action).

It's not much recourse, but you can also file a separate lawsuit for damages in 36th District court against the squatters. Defendant[[s) likely won't respond and you can get a default judgment for the damages you can prove. If the squatter/loser has an employer of any sort, you can give him a little grief through a wage garnishment. Another neat trick you might need a lawyer to help you with is after you get a money judgment - and if you can locate the asshole - you can serve him with a subpoena for what the lawyers call a creditors exam. This requires the squatter to show up at the lawyer's office and provide information about his [[probably non-existent) finances and assets. He won't show when required. Not showing up is considered contempt of court and the lawyer can have a judge issue a bench warrant for the squatter's arrest. The warrant goes into the system and if the squatter is stopped by the police for any reason, he'll get locked up. Even years later. Even if you never see any money, you might get some satisfaction from having the guy spend a few days in county jail.
