<prompt> Human: My bank was purchased by another bank. I have everything set up through my old routing numbers. Its a lot of accounts and would take quite a bit of time to switch over. My bank has one by one, started rejecting payments from my old routing number.Does the new bank just not have to honor the old banks routing and account numbers? I just was charged 25 for a check bounce because my bank didnt accept my routing information that has worked forever.What is the legal requirement here?  <response>: How about just biting the bullet and changing them rather then playing internet lawyer?
