Spousal Consent for 401(k), Pension and IRA Forms

Naming someone other than your spouse as beneficiary, taking a lump sum, or borrowing from a 401(k)? Federal law usually requires your spouse’s consent, witnessed by a notary.

Quick answer

Under federal law (ERISA), when a spouse gives up rights to a pension or 401(k) benefit, such as the survivor annuity or being the beneficiary, the consent must be in writing and witnessed by a plan representative or a notary public (29 U.S.C. § 1055(c)). The spouse is the one who signs and is notarized. In California, the notary completes the form’s notarial section or attaches a California certificate.

How the notarization works

  1. The plan sends the participant a form with a spousal consent section. Fill in everything but the signatures.
  2. The spouse signs the consent in front of the notary (or acknowledges it, if the wording is an acknowledgment) and shows acceptable ID.
  3. The notary completes the notarial wording. If the plan’s pre-printed notary block doesn’t comply with California law, which is common with forms written for every state, the notary attaches a California acknowledgment or jurat matching the plan’s wording.
  4. The participant usually signs too; their signature may or may not need notarization, depending on the form.

Don’t let the spouse sign the consent section ahead of time. Many plans reject consents that weren’t signed in the presence of the notary or plan representative.

What the notary can’t do

The notary can’t explain what rights the spouse is giving up; that is what the plan’s disclosures and, ideally, a financial or legal adviser are for. The notary only identifies the spouse and notarizes the signature.
