The TSP-3 Form: Why Your Beneficiary Designations Trump Your Will

The $400,000 Mistake

Under federal law, your Thrift Savings Plan (TSP) beneficiary designation overrides your last will and testament entirely, legally forcing the distribution of your retirement assets to whoever is named on the form even if you have since divorced.

Consider the case of Robert. He spent 32 years as a federal employee and built a TSP balance of $400,000. He divorced his first wife, Linda, in 1998 in an amicable split. He remarried in 2001 and raised two children with his second wife, Carol. Before retiring at age 62, Robert drafted a will that explicitly left his TSP to Carol.

Robert died of a heart attack four months after retirement.

Carol filed for the benefits, but the TSP sent the $400,000 to Linda.

Robert had never updated his TSP-3 form. The document on file still named his ex-wife. Under federal law, the TSP is required to pay whoever is named on the TSP-3 at the time of death, no exceptions (detailed in TSP Death and Beneficiary Support and the TSP Death Benefits Bulletin). His will, his 21-year marriage, and his personal intentions did not matter.

This situation occurs because beneficiary designation forms are legally binding contracts. They bypass probate entirely.

The Legal Basis: Why a Will Has No Power Over Your TSP

Your will governs your estate, but your TSP is not part of your estate.

The Thrift Savings Plan is governed by federal law — specifically 5 U.S.C. § 8424(d) and its death benefit regulations in 5 C.F.R. Part 1651. These statutes dictate that TSP funds must be distributed according to the valid beneficiary designation on file. The TSP cannot honor a will, a trust, or a divorce decree. As the TSP itself states in its official guidance on Designating Beneficiaries: "TSP cannot honor a will or any other document."

This is by design. Beneficiary forms bypass probate court to distribute assets quickly. The cost of this convenience is that the form you filed decades ago remains legally binding until you submit a new one.

The same rule governs your Federal Employees' Group Life Insurance (FEGLI) through the SF-2823 form. The Supreme Court upheld this federal supremacy in Hillman v. Maretta (2013). Federal law dictates that any designation in a will that conflicts with the properly filed SF-2823 has no legal force. The document on file with your agency controls the payout.

What Happens If You Never Filed a TSP-3?

If you die without a valid TSP-3 on file, the TSP distributes your account according to a fixed statutory order of precedence:

1. Your widow or widower

2. Your child or children equally (including adopted children, but not unadopted stepchildren), with descendants of deceased children receiving by representation

3. Your parents, equally or to the surviving parent

4. The executor or administrator of your estate

5. Your next of kin entitled to your estate under the laws of your state of residence at the time of death

For many employees, this default sequence works. The surviving spouse receives the money. However, if you are estranged from your spouse, want to provide for children from a previous marriage, or wish to leave the funds to your parents, the default order will fail you.

FEGLI follows a similar order of precedence through the SF-2823 framework. Without a valid designation, the money goes first to your surviving spouse, then to your children, then to your parents, and finally to your estate.

The Divorce Problem: When the Form Never Gets Updated

Divorce is the most common reason federal beneficiary designations fail.

The law does not automatically remove an ex-spouse from your beneficiary forms upon divorce. It does not matter if your divorce decree states that your ex-spouse waives all rights to your retirement benefits. It does not matter if you have a signed property settlement. As the 10th Circuit Court of Appeals confirmed in Evans v. Diamond (957 F.3d 1098, 2020), if your ex-spouse is named on your TSP-3 when you die, they receive the money. The waiver in your divorce settlement is ignored by the TSP.

The only exception during your lifetime is a Retirement Benefits Court Order (RBCO), which divides your TSP while you are alive. At death, the TSP-3 on file is the final word.

Updating your TSP-3 and SF-2823 must be your first priority when a divorce is finalized.

Federal Employees Retirement System (FERS) Survivor Benefits: A Separate and Critical Election

Your TSP-3 and SF-2823 do not affect your pension. The FERS survivor benefits election determines whether your spouse receives a lifetime monthly annuity after you die. This election operates under separate rules.

At retirement, you choose a survivor annuity option. The maximum election gives your surviving spouse 50% of your unreduced benefit. This choice requires spousal consent to waive or reduce.

• Divorce after retirement: You must notify Office of Personnel Management (OPM) and update your election following a qualifying life event. If a court orders a former spouse survivor annuity (FSSA) as part of your divorce, OPM is legally bound to honor it.
• Remarriage after retirement: You can elect a survivor annuity for a new spouse, but you must do so within two years of the marriage. If you miss this window, your new spouse will not receive your pension. This election also requires a permanent reduction in your monthly retirement check.

The system is not self-correcting. Every major life change requires manual updates.

The Two Federal Beneficiary Forms Most Employees Have Never Heard Of

Federal employees actually have four separate beneficiary systems. Each controls a different pool of money:

• SF 3102 — Designation of Beneficiary, FERS (see also OPM's administrative guidance in Civil Service Retirement System (CSRS)/FERS Handbook, Chapter 34A) — This form determines who receives a lump-sum payout of your FERS contributions if you die before retirement. It is entirely separate from your TSP. Filing this form does not elect a survivor annuity.
• SF 1152 — Designation of Beneficiary for Unpaid Compensation — This form designates who receives your final paycheck, unused annual leave payout, and other outstanding compensation. For employees with large leave balances, this payout can easily reach $10,000 to $30,000.

Updating your TSP-3 does not update SF 3102 or SF 1152. You must review and submit all four forms individually.

The Minor Children Trap

Naming minor children as direct beneficiaries on your TSP, FEGLI, or FERS forms creates significant legal hurdles.

Minors cannot legally manage large sums of money. If a minor is named as a beneficiary, a state court must appoint a guardian or conservator to manage the funds. This process is slow, expensive, and subject to court oversight.

To avoid this, you can name a trust as the beneficiary, name a custodian under the Uniform Transfers to Minors Act, or name your spouse as the primary beneficiary. You should discuss these options with both a federal benefits specialist and an estate planning attorney.

The Tax Side of Your TSP Beneficiary Choice

Your beneficiary designation is also a tax decision. Understanding the tax treatment of inherited TSP assets will prevent your heirs from facing a surprise tax bill.

Traditional TSP distributions are taxed as ordinary income. Roth TSP distributions are generally tax-free. However, the tax rules differ depending on who inherits the account:

• Spouse beneficiaries can roll the inherited TSP into their own IRA or TSP account to defer taxes and manage distributions over time.
• Non-spouse beneficiaries (such as children or siblings) cannot roll the funds into their own IRAs. They must withdraw the entire balance, usually within 10 years. A large TSP balance distributed over 10 years can push your heirs into much higher tax brackets.

Leaving a $500,000 traditional TSP to a child means they inherit the balance minus ten years of ordinary income taxes. You should factor this tax liability into your estate planning.

What Happens When TSP Passes to Your Estate

If you die without a valid beneficiary designation or living heirs in the order of precedence, your TSP goes to your estate.

This sends the funds through probate. Probate is a public, court-supervised process that can take months or years. It incurs court fees, executor fees, and subjects your retirement savings to creditor claims. Naming direct and contingent beneficiaries keeps your TSP out of court.

When to Update Your Federal Beneficiary Designations: A Checklist

Review and update your TSP-3, SF-2823, and FERS survivor benefit elections after any of the following events:

• [ ] Marriage — add your new spouse as primary or contingent beneficiary
• [ ] Divorce — remove your ex-spouse immediately; do not wait for other paperwork to settle
• [ ] Remarriage — update all forms and file your FERS survivor benefit election within two years
• [ ] Death of a named beneficiary — review all forms; a deceased primary beneficiary with no contingent named sends the account to the default order of precedence
• [ ] Birth or adoption of a child — update if you want to provide for children directly rather than through a spouse
• [ ] Death of a named contingent beneficiary — update your contingent designation
• [ ] A significant change in your estate plan — your attorney updates your will, but your beneficiary forms must be updated separately
• [ ] Any major change in your relationship with a named beneficiary — estrangement, addiction, incapacity, or simply changed wishes
• [ ] When you have not reviewed your forms in more than five years — do a routine audit regardless of life events

Frequently Asked Questions

Can I use my will to specify where my TSP goes instead of filing a TSP-3?

No. The TSP will not honor a will or any other estate document. Federal law is clear on this point. The only way to direct your TSP to a specific heir is to file a valid TSP-3 form.

My divorce decree says my ex-spouse waived all rights to my TSP. Isn't that enough?

No. Federal court precedent confirms that state court divorce decrees do not bind the TSP record keeper. The beneficiary named on the TSP-3 on file at the time of your death receives the money. You must update the form.

How do I file or update my TSP-3?

You can update your designations through your online account at tsp.gov or by submitting a physical form to the TSP record keeper. Keep a copy of the confirmation for your files.

Does my SF-2823 for FEGLI automatically update when I change my TSP-3?

No. These forms are processed by different entities. Your TSP-3 goes to the TSP record keeper. Your SF-2823 must be filed with your agency's HR department (or OPM if you are retired). Changing one does not update the other.

What if I want to leave my TSP to a trust rather than an individual?

You can name a trust as your beneficiary. However, the trust must meet specific TSP legal requirements. Consult both an estate planning attorney and a federal benefits specialist before filing this designation.

The Bottom Line: Forms Win. Intentions Lose.

The federal benefits system is built for legal clarity, not personal flexibility. This structure ensures that funds are distributed quickly, but it is unforgiving when designations are outdated.

Your will reflects your wishes, but your beneficiary forms establish your legal reality. When the two conflict, the forms win.

The TSP-3, the SF-2823, and your FERS survivor elections are binding legal instruments. They distribute your life savings without regard to what you intended or what your family expects. Review your forms, update them, and verify that OPM and the TSP have them on file.
