<prompt> Human: Grandma passed away a few years ago and had Life insurance policy. My dad is the executor of her estate. He tried to collect the policy. But there is an issue with the address on the account. Grandma never moved but the post office changed the address a few time in the 70 years she lived in that house. The state doesnt recognize any address we have tried. Any ideas on how to progress?  <response>: Ask the post office for previous possible addresses? I would think theyd have something on file. Otherwise, I would go down to your countycity courthouse and ask at whatever office holds the property tax records. They would have a record of nameaddressparcel taxes paidetc. If they dont have what youre looking for, they should be able to at least point you in the right direction. Or even check out local title companies, who close real estate deals. They have to do a search on the title of houses and ownership and from my understanding, it is very meticulous because they dont want Robert coming out of the woodwork when Bob says hes the ownerheir. Hope that helps!
