Fill these in and the letter below becomes yours — dated today, ready to print and send. Nothing is saved and you don't need an account.
Your letter asks what the institution requires. It won't claim you're authorised to act for the estate — only a court appointment gives you that, and saying so without one can hold up the process.

Most estates need this same letter for eight or nine institutions, not just MassMutual. Estate Assist finds them and drafts a letter for each.

Look for a small colored icon in the browser toolbar or on the phone's home screen. You'll need the master password to unlock it — never share that with anyone claiming to need it for notification purposes.
