A young man graduated from high school and got his first job. HR had a lot of forms for him to sign. One asked who he wanted as the beneficiary of his mandatory savings plan. He listed his girlfriend.
He soon broke up with the girlfriend but stayed with the employer. After many years of saving, he passed away, never updating his beneficiary. His children sued the girlfriend and lost. He could have changed beneficiary any time but did not.
Everyone needs to check and update the beneficiary on all bank, investment, and retirement accounts.
