When Beneficiary Designations Fail in California: ERISA, the SECURE Act & Community Property — DeCosimo Law 06/08/2026

Did you name your grandchildren on your retirement account? In California, that may not be enough.

Most people assume a signed beneficiary designation form settles the question of who inherits their retirement savings. But California families face three separate legal obstacles that can override that form entirely — and most people have never heard of any of them.

① Federal ERISA spousal consent rules can void a 401(k) or pension beneficiary designation if your spouse never signed a notarized waiver — no matter whose names are on the form.

② The SECURE Act (2020) eliminated the "stretch IRA" that allowed grandchildren to draw on inherited retirement accounts slowly over a lifetime. Today, most non-spouse beneficiaries must empty the account within 10 years — often during their highest-earning, highest-taxed years.

③ California community property law means your spouse may already legally own half of your IRA — even a personal IRA in your name only — making any designation that ignores that ownership vulnerable to a legal challenge after your death.

We walk through a real San Fernando Valley family's story and break down how all three of these laws collided to unravel a plan that looked perfectly reasonable on paper.
If you haven't reviewed your beneficiary designations recently — especially if they were set up before 2020 — this is worth a read.
