Cash Balance Plan in Divorce

If a settlement agreement treats a cash balance plan like a 401(k), the QDRO will be rejected. The mistake is so common that it has its own pattern in plan-administrator rejection letters. The fix is drafting the order to what the plan actually is: a defined-benefit pension that shows an account balance on the statement.

A cash balance QDRO is a $700 flat project fee, the same as any private defined-benefit pension order. Marital and non-marital tracing, when the account predates the marriage, is quoted separately.

What is a cash balance plan?

A cash balance plan is a defined-benefit pension plan that shows a hypothetical account balance on participant statements. Each participant has an account credited each year with:

• A pay credit, typically a percentage of salary set by the plan formula.
• An interest credit, either at a guaranteed rate (often a Treasury-linked rate) or at a market-linked rate, again set by the plan formula.

The "account" is not a real account holding actual dollars. It is a notional balance that represents the participant's accrued benefit under the plan's formula. The employer funds the plan to support the promised benefit and bears the investment risk if the plan's actual assets do not match the promised account growth.

Cash balance plans are common at law firms (especially firmwide partner cash balance arrangements alongside a 401(k)), medical practices and physician groups, dental partnerships, accounting firms, and other professional partnerships. They are also used by some corporations as the conversion form of a frozen defined-benefit pension.

Why a cash balance plan is not a 401(k)

The silent risk: DC-style language on a DB plan

The plan administrator looks at the order, sees DC-style segregation and gains-and-losses language, and rejects it because the plan cannot administer those mechanics. The plan does not hold actual segregated dollars. It holds an obligation to pay a benefit based on a formula. The order has to ask the plan to do something the plan actually does.

How a cash balance plan is actually divided

The QDRO is drafted as a defined-benefit order. The most common structures:

1. Fixed dollar award. The order awards the alternate payee a specific dollar amount from the participant's hypothetical account balance as of a stated valuation date. The alternate payee's share grows at the same interest credit rate the plan applies to the participant's share, from the valuation date until payment.
2. Percentage award. The order awards the alternate payee a percentage of the participant's hypothetical account balance as of a stated valuation date. Same interest credit treatment going forward.
3. Coverture-fraction award (less common on cash balance). Some plans accept a coverture fraction approach on the accrued benefit, similar to traditional pension division. Plan-specific.

The order has to match the cash balance plan's specific QDRO procedures, which often differ from the firm's 401(k) procedures. A firm that has both a 401(k) and a cash balance plan typically has different QDRO units, different required language, and different timelines for each.

Big Law cash balance plans

Most major U.S. law firms have a firmwide partner cash balance plan in addition to (or instead of) a 401(k). The cash balance plan is a defined-benefit plan with the firm's name on it, governed by the firm's plan document, administered through a plan administrator (sometimes the firm, sometimes a third-party recordkeeper).

The pattern repeats: the partner's statement shows a six- or seven-figure cash balance "account," the divorcing parties agree to divide it, the agreement uses 401(k)-style language, and the QDRO gets rejected because the plan is defined-benefit.

TOVA routinely handles cash balance plans at law firms across the AmLaw 200, corporate partnerships, and similar professional partnerships. The work is plan-specific: identifying the cash balance plan inside the firm's broader retirement structure, pulling the firm's QDRO procedures, and drafting the order as a defined-benefit QDRO.

Medical and dental practice cash balance plans

Physician groups, dental practices, and other medical partnerships frequently maintain cash balance plans for higher-earning partners alongside a 401(k) for staff. The same pattern applies. The cash balance plan is the larger asset for the partner in most cases, and treating it as a 401(k) at settlement is the single most consequential drafting mistake we see in physician divorces.

Cash balance plan red flags at settlement

Before the agreement is signed, watch for:

• Account-style balances on statements from a firm or practice rather than a brokerage.
• "Pay credit" and "interest credit" lines on the statement.
• A plan name that includes "Cash Balance," "Cash Balance Plan," or "Cash Balance Component."
• A plan administered alongside a separately named 401(k) plan at the same firm.
• An interest credit rate that does not match the participant's actual investment returns.
• A statement that shows the same growth rate year after year regardless of market performance.

Any of these is enough to require defined-benefit treatment. All of them together make the plan unambiguously cash balance.

What TOVA does not do

• We do not provide legal advice. Counsel makes the legal calls.
• We do not provide tax advice. The client's CPA handles tax.
• We do not make strategic litigation decisions. We document what the records show and what the plan can administer.
• We do not opine on whether a partnership agreement supersedes the cash balance plan division. Counsel handles that.

What we need to start

• The most recent cash balance plan statement.
• The Summary Plan Description (SPD) or the plan document, especially the QDRO procedures section.
• The settlement agreement language addressing the cash balance plan.
• The Date of Marriage and the cutoff date.
• The participant's expected service end date or retirement age, if relevant to the analysis.
