<prompt> Human: What questions should I ask and what are some legitimate scenarios in which we should provide SSN? Story: My wifes grandfather recently died and now her step grandmother has asked for her SSN for inheritance reasons. We just got the message and are skeptical. While nobody likes step grandma I dont think she is trying to scam us. But want to be careful in case she is being scammed or her children, not my wifes family, are trying something. We do not have any estate info. It is very plausible grandpa did have a decent amount of money though. I plan on asking step grandma questions like was she contacted by a previously unknown person asking for this? Is this something grandpa had discussed prior? Is there an attorney involved we can speak to? Are there legal documents we can see? Etc.Add info. State is Ohio, they were married for 15years, and we are not aware of any prenuptial agreement at the moment.  <response>: Hire a Lawyer, deal with them only through your lawyer. Legitimize all documentation, otherwise most likely a scam to rob you of rightful monies. Dont ask me how I know this...
