My mother passed away and I called Mass Mutual to handle her account. They mailed me a printed pdf to fill out. Well, I filled it out wrong and started hunting the internet for the form. I couldn’t find it anywhere. In fact, when I called, they needed approval to send me the PDF. The amount of time to get this form was so ridiculous I vowed to put it online. And here it is the:.beneficiary-distribution-election-form-RS-38467-01-Rev-7-18-benelg.pdf form. Use it, print it, do what you like.
