<prompt> Human: My grandpa passed away a few years ago. He had a savings account with Chase. We didnt know how much was in it - just that it existed. My mother would deposit money from time to time in the account. Today, we got a letter from Chase stating that there must be new activity on the account, or the state will claim the money. The letter told us the sum and its enough to try and claim it. How do we claim the money? My grandpa had no will, as far as i know. And his primary residence was in the UK, but the saving account is in the US.  <response>: i know its been a while but sorry for your loss, contact the bank and they will get u to the estate dept, then you will send them paper work and a check will be mailed. be prepared when you call with his info and the circumstances of his passing. date he passed who the exexuter of estate is or whoever is handling this and a phone number abd address for future contact.
