Dividing Retirement Accounts and QDROs in a Montana Divorce

Retirement savings are divided in a Montana divorce like other property: the court equitably apportions them under MCA § 40-4-202(1). What makes them different is the second step. A workplace retirement plan generally cannot pay anyone except the employee unless it receives a qualified domestic relations order (QDRO) that meets federal requirements. IRAs, government pensions, and military retired pay each have their own procedure. This page is part of our Montana Divorce Guide.

Retirement Benefits Are Property

The Montana statute reaches "the property and assets belonging to either or both, however and whenever acquired." The disclosure statutes define an asset to include property that is intangible or contingent (MCA § 40-4-251(1)), and the automatic restraining order specifically names deferred compensation, retirement, profit-sharing, pension, and employee benefit plans, IRAs, and Keogh accounts. Both spouses must list their plans in their financial disclosures.

How much each spouse receives is an equitable question under the usual factors. See how property is divided in Montana.

Why a Decree Alone Is Not Enough

Federal pension law requires covered plans to provide that benefits "may not be assigned or alienated" (29 U.S.C. § 1056(d)(1)). A divorce decree that awards a spouse part of a 401(k) or pension does not, by itself, get around that rule. The statute makes one exception: the plan must pay benefits in accordance with a domestic relations order that is determined to be a qualified domestic relations order (29 U.S.C. § 1056(d)(3)(A)). The tax code has a matching definition (26 U.S.C. § 414(p)).

So there are two documents. The decree or settlement agreement states the division. The QDRO is the separate order addressed to the plan.

What a QDRO Must Say

To qualify, a domestic relations order must clearly specify (29 U.S.C. § 1056(d)(3)(C)):

• The name and last known mailing address of the participant, and the name and mailing address of each alternate payee.
• The amount or percentage of the participant's benefits to be paid to each alternate payee, or the manner in which it is to be determined.
• The number of payments or the period to which the order applies.
• Each plan to which the order applies.

And it must not (29 U.S.C. § 1056(d)(3)(D)):

• Require the plan to provide any type or form of benefit, or any option, the plan does not otherwise provide.
• Require the plan to provide increased benefits, determined on the basis of actuarial value.
• Require payment to an alternate payee of benefits already required to be paid to another alternate payee under an earlier QDRO.

A QDRO may also provide that a former spouse is treated as the participant's surviving spouse for the plan's survivor annuity rules (29 U.S.C. § 1056(d)(3)(F)). For a pension that pays monthly for life, that provision can matter as much as the percentage does.

The Plan Administrator Decides Whether It Qualifies

A judge signs the order, but the plan decides whether it is "qualified." When a plan receives a domestic relations order, the administrator must promptly notify the participant and each alternate payee and, within a reasonable period, determine whether the order is a QDRO. Each plan must have written procedures for doing so (29 U.S.C. § 1056(d)(3)(G)). While the question is pending, the administrator separately accounts for the amounts that would be payable to the alternate payee (29 U.S.C. § 1056(d)(3)(H)).

Because every plan's terms and procedures differ, the practical advice is the same in almost every case: get the plan's QDRO procedures early, and do not treat the division as finished until the plan has accepted the order. Our page on getting the QDRO done covers the follow-through after the decree.

Which Order Fits Which Account

Government plans follow their own statutes. See Montana public pensions in divorce and military pensions and benefits in divorce. Federal civilian pensions and plans from other states have their own rules too, and the plan itself is the place to confirm them.

Taxes and Early Withdrawal: The Short Version

The tax code speaks to these transfers in a few places, and you should take the details to a CPA or tax attorney:

• A spouse or former spouse who receives a distribution as an alternate payee under a QDRO is treated as the distributee for income tax purposes, and may roll the distribution over as if they were the employee (26 U.S.C. § 402(e)(1)).
• The 10 percent additional tax on early distributions does not apply to a distribution to an alternate payee under a QDRO (26 U.S.C. § 72(t)(2)(C)). That exception does not apply to distributions from an IRA (26 U.S.C. § 72(t)(3)(A)).
• A transfer of an IRA interest to a spouse or former spouse under a divorce or separation instrument is not treated as a taxable transfer (26 U.S.C. § 408(d)(6)).

A dollar in a pre-tax account is not worth the same as a dollar of home equity or cash. Comparing them fairly is a tax question, which is why we suggest a tax professional review a proposed trade. See taxes the year you divorce.

Privacy and the Rules While the Case Is Pending

QDROs contain account details and personal identifiers. Montana requires the court to seal any QDRO issued in a dissolution, except for access by the plan administrator, the child support enforcement division, the parties, and each party's counsel of record (MCA § 40-4-202(6)).

Until the decree, the automatic economic restraining order restrains both spouses from withdrawing or borrowing from retirement plans and IRAs, and from changing the beneficiary on any account or asset (MCA § 40-4-126(1), order paragraphs 3(c) and 3(e)). Beneficiary designations after the decree are their own subject. See life insurance and beneficiaries in divorce.
