I just got a bill from my Chiropractor from 5 years ago. Do I have to legally pay for this? 
That 's an interesting question ! It sounds as if you admit that you 've used the Chiropractor 's services , and that you are admitting that the bill in question is legitimate . If that 's the case , it also seems like at the time you might have realized there was a mistake in the billing if you 'd not had to pay ? Perhaps they 've had a billing issue , and they 've just now found it -LRB- stranger things have happened -RRB- . Unless you can show you have already paid for the service , yes , morally at least you 're obligated to pay , and most likely legally also . I 'm absolutely certain that paying them will be infinitely better for you than having the bill go to collections and having a debt company buying it and getting a hefty judgement against you while trashing your credit -LRB- that 's a multibillion dollar business , by the way -RRB- . If you owe it , pay . Thanks for asking !
