<prompt> Human: So I have been trying to clean up a lot of bills after buying a house almost 2 years ago I am divorced, for almost 10 years January 2019 Two weeks ago I started getting phone calls from an 800 number asking me to call back and they used both my married last name and my current last name. I didnt return the calls, figured they were scam calls. Yesterday I got a letter from the this company saying I owed Citibank 223 from an account that is over 10 years old. My questions are:1. Is this legit?2. Can they come after me after 10 years?3. Can this be put back on my credit report?This never came up during my Home purchase and they scrutinized everything!Thanks!Update, to answer questions, I live in Michigan and the collection company is from Pennsylvania.  <response>: 1. Is this legit?It could be an actual debt of yours. Can they come after me after 10 years?The statute of limitations is what determines that. The highest ones are only 10 years. So that would depend on how close to 10 years ago that debt went delinquent and what state you are in.Can this be put back on my credit report?No. After 7 years, all bad debt gets removed from your credit report, independent of your states statute of limitations.If they continue to call, inform them they are only to contact you in writing.Most likely this is a company that buys bad debt that is beyond the statute of limitations. They then attempt to get the debtor to pay, even though the debtor has no legal obligation to. Dont pay. Dont acknowledge the debt on the phone. Dont try to make a goodwill payment. I dont know your particular state and its laws, but in some states it is easier than in others to reset the statute of limitations.
