Dividing Retirement Accounts in a New Hampshire Divorce

Retirement accounts are often the second-largest asset in a New Hampshire divorce after the family home — and they're the most likely to be divided incorrectly. A mistake here can trigger unexpected tax bills, early withdrawal penalties, or a division that doesn't actually get executed because the paperwork was wrong.

New Hampshire's all-property rule under RSA 458:16-a means the court has authority over all retirement assets, including funds accumulated before the marriage. Here's how each type of account gets divided.

Defined Contribution Plans: 401(k), 403(b), IRAs

These accounts have a clear cash balance, which makes valuation straightforward — pull the most recent statement and you know what they're worth. The division depends on the account type.

Employer plans (401(k), 403(b), 457)

Dividing an employer-sponsored retirement plan requires a Qualified Domestic Relations Order (QDRO) — a specialized court order that instructs the plan administrator to transfer a specific percentage or dollar amount to an account in the non-employee spouse's name.

A standard divorce decree, no matter how clearly it states "Spouse B gets 50% of the 401(k)," is not sufficient. The plan administrator will reject it. You need a separate QDRO that's approved by the court and then "qualified" by the plan.

When properly executed, a QDRO allows a tax-free transfer. The receiving spouse (called the "alternate payee") doesn't owe taxes until they make withdrawals in retirement. They can also roll the funds directly into their own IRA to maintain the tax-deferred status.

IRAs (Traditional and Roth)

IRAs don't require a QDRO. Instead, they're divided through a "transfer incident to divorce" under IRC Section 1041. The divorce decree or settlement agreement specifies the division, and the IRA custodian processes the transfer directly.

The critical step: the transfer must be made directly from one IRA to another IRA in the receiving spouse's name. If the account holder withdraws the funds and hands the other spouse a check, the IRS treats it as a taxable distribution — potentially with a 10% early withdrawal penalty if either party is under 59½.

The QDRO Process Step by Step

1. Draft the QDRO. Either party's attorney (or the parties themselves in an uncontested case) prepares the order using language the plan administrator will accept. Many plan administrators provide model QDRO templates — request one before drafting a custom order.

2. Pre-approve with the plan administrator. Before submitting the QDRO to the court, send a draft to the plan administrator for review. They'll flag any language that doesn't comply with their plan document. This saves months of back-and-forth after the order is signed.

3. Submit to the court. Once the plan administrator approves the draft language, file the QDRO with the Circuit Court Family Division for the judge's signature.

4. Send the signed QDRO to the plan. The plan administrator has a processing period (typically 30 to 90 days) to "qualify" the order and execute the transfer.

5. Verify the transfer. Confirm with both the plan administrator and the receiving spouse that the correct amount was transferred to the correct account.

The biggest mistake people make: waiting months or years after the divorce to prepare the QDRO. During that gap, the account value changes, the employee spouse may take loans or distributions, and the plan terms may change. Get the QDRO drafted and submitted as part of the divorce process, not as an afterthought.

What About Premarital Retirement Funds?

Under the all-property rule, premarital retirement contributions are part of the marital estate. The 2025 LeGault decision reinforced this — the Supreme Court ruled that automatically excluding premarital retirement accruals conflicted with RSA 458:16-a.

However, the court can still award the premarital portion to the employee-spouse as part of the overall equitable distribution. The key is documenting the premarital balance with account statements from the date of the marriage. This gives the court a clear picture of what existed before and what was accumulated during the marriage.

Tax Traps to Avoid

A $100,000 balance in a traditional 401(k) is not worth $100,000 in real purchasing power. Future withdrawals are taxed as ordinary income — at current rates, the effective value might be closer to $70,000-$80,000 depending on the recipient's tax bracket.

When negotiating the division, account for these "embedded tax liabilities." If one spouse keeps the house (tax-free equity under the home sale exclusion) and the other gets the 401(k) (fully taxable upon withdrawal), the spouse with the retirement account needs a larger share to achieve equal after-tax value.
