I'm wondering if someone can help me make sure I submit a form 56 to the correct address.  The trust is in MA, however, the home where the decendent lived has already been sold and the trustee taking care of the returns is in OK.  The last 6 months of her life, the decendent lived with her daughter, and her daughter thought she had to change her mom's address with the agencies.  So now, even though the trust is still a MA trust, the address for any mail, including to the trustee is in OK.  Do I mail the form 56 to Kansas City or to Ogden?  The other sibling lives in a different state as well so changing the address at this point doesn't really help, and I just want to get these forms submitted and off my desk.
