Beneficiary Designations in 2026: How to Update Your 401(k), IRA, HSA, and Life Insurance After Marriage, Divorce, or a New Child
A marriage, divorce, or new child can change who you want to inherit your money—but it may not change the beneficiary forms already on file. If an old 401(k) still names a former spouse or a life insurance policy lists a deceased relative, the financial institution may be required to follow that designation.
Updating a will is important, but it is not enough. Retirement accounts, life insurance, health savings accounts, annuities, and payable-on-death or transfer-on-death accounts generally pass according to their own beneficiary instructions. Each account must be reviewed and updated separately.
This guide explains how to complete a beneficiary review in 2026 and what to check after marriage, remarriage, divorce, birth, or adoption. It provides general educational information, not individualized legal, tax, or financial advice.
Why Beneficiary Designations Matter More Than Your Will
A beneficiary designation is an instruction telling an account custodian, retirement plan, or insurance company who should receive an asset after the owner’s death. Assets commonly controlled by these instructions include:
- 401(k), 403(b), and other employer retirement plans
- Traditional, Roth, SEP, and SIMPLE IRAs
- Health savings accounts
- Life insurance policies and annuities
- Certain pension benefits
- Payable-on-death bank accounts
- Transfer-on-death brokerage accounts
These assets usually pass outside probate when a valid beneficiary is on file. That can make settlement faster, but it also means the directions in a will generally cannot replace an outdated account designation.
A Six-Figure 401(k) Example
Suppose Alex named a spouse as the sole beneficiary of a 401(k) in 2012. Alex later divorced, remarried, had two children, and updated a will to leave everything to the new family. The old 401(k) form, however, was never changed.
If the account is worth $450,000 when Alex dies, the plan administrator may have to distribute it according to the plan records and applicable federal law—not the later will. A dispute among the former spouse, surviving spouse, and children could be expensive, slow, and unsuccessful.
The practical lesson is straightforward: changing one document does not update every account. A new will does not automatically revise a 401(k), and changing a workplace retirement plan does not change an IRA or insurance policy.
Create a Complete Beneficiary Account Inventory
Start by locating every asset that can carry a beneficiary, payable-on-death, or transfer-on-death designation. Do not limit the search to accounts you actively use.
Retirement Accounts
- Current and former employer 401(k) plans
- 403(b), 457, pension, and profit-sharing plans
- Rollover accounts created after changing jobs
- Traditional and Roth IRAs
- SEP and SIMPLE IRAs connected to current or former businesses
Insurance and Other Financial Accounts
- Individual and employer-provided life insurance
- Health savings accounts
- Annuities
- Bank accounts with payable-on-death instructions
- Brokerage accounts registered as transfer on death
- Deferred compensation and employee stock plans with death benefits
For each item, record the institution, account or policy identifier, account owner, insured person, primary beneficiaries, contingent beneficiaries, allocation percentages, and last review date. Avoid placing full account numbers or Social Security numbers in an unsecured spreadsheet.
A contingent beneficiary receives the asset if no primary beneficiary is eligible or survives under the governing terms. Naming contingents can help prevent the asset from defaulting to the estate when the primary beneficiary dies first.
How to Update Beneficiaries After Marriage or Remarriage
Marriage does not produce identical results across every type of account. Employer retirement plans may have federal spousal protections, while IRAs and insurance policies operate under different contracts and laws.
Check Spousal Rights in Employer Plans
Many qualified employer retirement plans require a married participant’s spouse to be the beneficiary of some or all of the account unless the spouse signs a valid waiver. Depending on the plan, consent may need to be witnessed by a plan representative or notary.
Do not assume a premarital beneficiary remains effective after marriage. Ask the plan administrator or benefits center whether marriage changed the designation and whether spousal consent is required to name someone else.
Review Every Account Separately
Add the new spouse where intended, then name contingent beneficiaries. Repeat that process for old workplace plans, every IRA, personal and employer life insurance, HSAs, annuities, and POD or TOD accounts.
Remarriage deserves special attention because it may involve a current spouse, children from an earlier relationship, stepchildren, and obligations under a prior divorce agreement. Stepchildren generally should not be assumed to qualify as beneficiaries unless they are expressly named or covered by the relevant document.
Coordinate a Blended-Family Plan
A designation such as “100% to my spouse” is simple but may not ensure that remaining assets eventually reach children from a prior relationship. Alternatives may include percentage allocations or a properly drafted trust, although each choice can create different tax, control, and administrative consequences.
For example, an owner might designate 60% to a spouse and divide 40% equally among adult children. Another family might use a trust to provide income or support for the spouse while preserving remaining assets for children. Trusts as retirement-account beneficiaries require careful drafting because tax and distribution rules can be complex.
Compare all new forms with the will, revocable trust, and any prenuptial or postnuptial agreement. A private agreement alone may not satisfy an employer plan’s formal beneficiary or spousal-waiver procedures.
How to Update Beneficiaries After Divorce
Before removing an ex-spouse, read the final divorce decree, settlement agreement, and any applicable court orders. Some agreements require a former spouse to remain insured or require life insurance to secure child support, spousal support, or another obligation.
Prioritize Employer Retirement Plans
Most private-sector 401(k) plans are governed by the federal Employee Retirement Income Security Act. State laws that automatically revoke an ex-spouse after divorce may not control the plan. Administrators generally rely on plan documents, valid beneficiary records, and applicable federal orders.
A qualified domestic relations order, or QDRO, may also award retirement benefits to a former spouse. Changing a beneficiary form cannot eliminate rights already created by a valid QDRO.
Contact each plan’s benefits center, submit its required form, and confirm that the change was processed. Do this even if the divorce decree says each party waived an interest in the other’s retirement assets.
Update IRAs Directly
IRAs are not governed by ERISA in the same way as employer retirement plans. Some states automatically revoke certain beneficiary designations at divorce, while others provide different rules or exceptions. Relying on an automatic-revocation law creates avoidable uncertainty, especially if the owner later moves to another state.
Submit a new designation to every bank, brokerage, or credit union holding an IRA. Updating one IRA does not change another, even when both appear in the same financial dashboard.
Review Life Insurance Before Making Changes
A divorce order may require continued life insurance for children, support payments, or property-settlement obligations. Confirm the required policy amount, beneficiary, ownership, and coverage period before removing anyone.
Once legal obligations are clear, replace outdated beneficiaries and add new contingent beneficiaries. Verify both personally purchased policies and coverage obtained through work.
What to Change After the Birth or Adoption of a Child
A child cannot add themselves to an existing beneficiary form. Parents should review all designations after a birth or adoption and again when another child joins the family.
Avoid Naming a Minor Without a Management Plan
It may be possible to name a minor directly, but a financial institution or insurer generally cannot hand substantial assets directly to a young child. A court-supervised guardianship or conservatorship may become necessary, adding expense and limiting flexibility.
Possible alternatives include:
- A trust created under an estate plan
- A testamentary trust established through a will
- A custodian under the applicable Uniform Transfers to Minors Act
- A designation to a properly drafted special needs trust when appropriate
These options are not interchangeable. A custodial arrangement may terminate at an age set by state law, potentially giving the child full control earlier than the parent intended. A trust can provide more detailed instructions but involves drafting and administration costs.
Review Percentages and Family Branches
Allocation percentages should total 100% at each beneficiary level. If three children are intended to receive equal shares, the form might use 33.34%, 33.33%, and 33.33%, depending on the institution’s system.
Also decide what should happen if a child dies before the account owner. A “per stirpes” designation generally directs that child’s share to the child’s descendants. A “per capita” distribution may divide the asset among the surviving beneficiaries instead. Definitions and available options can vary by form, so read the institution’s instructions.
Review the plan again after adoption, a guardianship change, the birth of another child, a beneficiary’s death, or a change in a child’s health or financial needs.
Account-by-Account Beneficiary Update Checklist
401(k) and Other Employer Plans
- Sign in to the official plan portal or call the benefits center.
- Confirm the current primary and contingent beneficiaries.
- Check whether spousal consent, notarization, or supporting documents are required.
- Review old plans from previous employers instead of checking only the current plan.
- Confirm that the completed designation appears in the plan’s records.
Traditional, Roth, SEP, and SIMPLE IRAs
- Update the designation at the institution that legally holds each IRA.
- Specify primary and contingent beneficiaries and verify percentages.
- Ask whether per stirpes or customized instructions are available.
- Get legal and tax advice before naming a trust or estate.
Health Savings Accounts
- Confirm whether the HSA provider has a beneficiary on file.
- Review the designation after marriage or divorce instead of assuming the provider will update it.
- Understand that a surviving spouse generally can treat an inherited HSA as their own HSA.
- Understand that a nonspouse beneficiary generally recognizes taxable income based on the account’s value, subject to applicable deductions and exceptions.
If the estate is the beneficiary—or no beneficiary is effectively named—the HSA’s value may be included on the deceased owner’s final income tax return. Because HSA treatment differs sharply between spouses, nonspouses, and estates, tax advice can be especially valuable.
Life Insurance
- Verify the policy owner and insured person.
- Check individual, employer, and association policies.
- Name primary and contingent beneficiaries.
- Confirm whether a trust or custodial arrangement should receive proceeds intended for a minor.
- Check whether an irrevocable beneficiary or court order limits changes.
Save Proof of Every Update
Keep confirmation numbers, dated screenshots, submitted forms, acceptance notices, and relevant correspondence. A copy of a form proves what was requested; confirmation from the institution helps establish that the request was processed.
Store records securely and tell a trusted executor, trustee, or family member where the account inventory can be found. They do not necessarily need account passwords, which should remain protected.
Common Beneficiary Mistakes
- Assuming a life event updates every account: Marriage, divorce, birth, or adoption does not reliably rewrite all existing forms.
- Updating only the will: A will usually does not override a valid beneficiary designation.
- Stopping after one account: Each employer plan, IRA custodian, HSA provider, insurer, bank, and brokerage maintains separate records.
- Naming an estate without analysis: This may introduce probate, creditor, distribution, and tax consequences.
- Naming a minor directly without a plan: Court involvement may be required before funds can be managed or distributed.
- Forgetting contingent beneficiaries: The asset may fall to the plan’s default beneficiary or the estate if the primary beneficiary dies first.
- Ignoring percentages: Incomplete or inconsistent allocations can delay processing or produce unintended results.
- Failing to verify the change: An unsigned, rejected, or incomplete form may leave the old designation in place.
What to Do Next
- Create a list of every retirement account, HSA, insurance policy, annuity, pension, and POD or TOD account.
- Download or view the current beneficiary record for each asset.
- Read any divorce decree, support order, prenuptial agreement, postnuptial agreement, or QDRO that may restrict changes.
- Choose primary and contingent beneficiaries, including a suitable structure for minor children.
- Submit updates directly through each institution’s required process.
- Save proof and verify that every change was accepted.
- Compare the completed designations with the will and trust.
Review beneficiary designations at least annually and after marriage, remarriage, divorce, birth, adoption, a beneficiary’s death, a job change, retirement, inheritance, or the opening or rollover of an account.
Consult an estate-planning attorney or qualified tax professional when the plan involves trusts, minor beneficiaries, special needs, community-property rights, a blended family, an estate as beneficiary, or obligations imposed by divorce. The goal is not merely to fill out forms—it is to make every form work together as one coherent estate plan.
