These collection company will always come after you even after 10 or 20years. You just have to pretend that it is not you. Again once the negative deliquency is gone after 7 years then it does not matter even if they call you. JUST HANG UP. Dont say you will pay up, then it will go in your credit for about  more years. Now regarding the court coming after you, it depends on what state are you and what is the statute of limitation at that particular state.

If the statute of limitation is over, the company can't take you to court, they will only try to threaten you but they can't do S/H/I/T
