<prompt> Human: My landlord just called to inform me that theyve audited my account, and found some late fees that I owe. Some of the fees date back to July of 2016. I havent checked my records to verify that I paid late, but I dont necessarily doubt it.My question is: at what point should they accept some of the responsibility for not getting paid? Weve signed a new lease since these fees were incurred, without any objections from them. Ive never gotten any notification that there was an outstanding debt, until now. Are they shaking me down?  <response>: rlegaladvice and include the state.Most states enforce a grace period of something like 3 to 5 days for the rent due date. There could be other legal reasons why they cant collect old fees like this.
