Beneficiary Designation Mistakes That Override Your Estate Plan
Beneficiary forms, not your will, decide who inherits retirement accounts, life insurance, and TOD accounts. Outdated or missing names cause most failures.
Beneficiary Designation Mistakes That Override Your Estate Plan
1 / 7
Do beneficiary designations override a will?
- Yes. Retirement accounts, life insurance, annuities, and transfer-on-death or payable-on-death accounts pass to the named beneficiary, regardless of what your will says.
- Your will and trust only control these assets when the estate or trust is the named beneficiary, or when no valid beneficiary survives.
- That makes the forms on file with each custodian and insurer as important as the estate documents themselves.

Do beneficiary designations override a will?
- Yes. Retirement accounts, life insurance, annuities, and transfer-on-death or payable-on-death accounts pass to the named beneficiary, regardless of what your will says.
- Your will and trust only control these assets when the estate or trust is the named beneficiary, or when no valid beneficiary survives.
- That makes the forms on file with each custodian and insurer as important as the estate documents themselves.
What are the most common mistakes?
- Leaving an ex-spouse named after a divorce, or never adding a new spouse or child after marriage or a birth.
- Naming no contingent beneficiary, so the account falls back to the plan's default, often your estate, if the primary beneficiary dies first.
- Opening new accounts or changing jobs without completing a designation on the new 401(k), IRA, or policy.
- Naming a minor directly, which can require a court-supervised guardianship or custodianship before anyone can manage the money.
Does divorce automatically remove an ex-spouse?
- California law generally revokes a former spouse's nonprobate transfers at divorce, but it does not reach every account type.
- For ERISA plans such as most 401(k)s, federal law controls and the Supreme Court has held the plan pays whoever is on the form.
- Many employer plans also require your current spouse to be the beneficiary unless the spouse signs a written, witnessed consent.
- Updating every form after a divorce is simpler than relying on a statute that may not apply.
How do per stirpes, per capita, and contingent beneficiaries differ?
- Per stirpes passes a deceased beneficiary's share down to that person's descendants.
- Per capita typically divides the account among the named beneficiaries who survive, so a deceased beneficiary's children may receive nothing.
- Custodians define these terms in their own forms, so check each institution's wording rather than assuming a standard meaning.
How do inherited retirement account rules affect the choice?
- Most non-spouse beneficiaries must empty an inherited IRA or plan account by the end of the 10th year after the owner's death.
- If the owner had already reached their required beginning date, those beneficiaries generally must also take annual distributions in years one through nine.
- Surviving spouses, minor children of the owner, disabled or chronically ill beneficiaries, and people not more than 10 years younger have more flexible options.
- A trust named as beneficiary must meet specific IRS requirements to be treated as a see-through trust; drafting matters.
What about life insurance and naming your estate?
- Naming your estate sends proceeds through probate, where they may be exposed to the estate's creditors and delays.
- If you own a policy on your own life at death, the proceeds are generally included in your taxable estate even when paid to a named beneficiary.
- When the owner, insured, and beneficiary are three different people, paying the claim can be treated as a gift from the owner to the beneficiary.
Key takeaways
- Beneficiary forms control more wealth than most wills, so review them after every marriage, divorce, birth, death, or job change.
- Name contingent beneficiaries and avoid naming minors directly.
- Inherited-account distribution rules differ by beneficiary type, which affects who you name.
- Rubric reviews designations as part of overall wealth management and coordinates changes with your estate attorney.
