California spousal support hub / Marriage length and duration
By H. William Edgar, California family law attorney at Edgar & Dow.
After a 20-year marriage, California spousal support may continue for many years, but there is no automatic lifetime award or fixed monthly percentage. A marriage of that length falls within the statutory presumption of long duration, which is important to the court’s continuing authority. The amount and duration still depend on the parties’ circumstances and the judgment’s terms.
The practical issues often extend beyond current wages. Retirement, health, time outside the workforce, the income produced by divided property, and the cost of maintaining two households may shape the support decision. This article focuses on those planning and proof questions.
Long duration preserves an issue that must still be decided
Family Code section 4336 presumes that a marriage of 10 years or more from marriage to separation is of long duration for retaining support jurisdiction. Absent a contrary written agreement or an order terminating support, the statute provides for indefinite retention of jurisdiction in a long-duration marriage.
Retention of jurisdiction is not the same as an order to pay forever. It preserves the court’s ability to address support when the applicable requirements are met. The court may order a payment, reserve the issue without a current payment, or make another appropriate ruling based on the evidence.
The general half-length measure in section 4320(l) does not govern long-duration marriages. Twenty years of marriage does not therefore create an automatic 10-year award. The appropriate duration must be supported by the actual circumstances.
Reconstruct the marital standard of living with financial evidence
After a long marriage, the parties may remember their lifestyle differently. Tax returns, spending records, housing costs, savings practices, travel, insurance, and other evidence can help establish the standard of living and distinguish ordinary expenses from unusual years.
The standard of living is an important reference point under section 4320, but it does not guarantee that each spouse can reproduce the former household’s lifestyle after separation. Two households may cost more, and retirement or other changes may reduce available resources.
Our marital-standard-of-living article explains how to present that evidence. A useful budget connects the historical lifestyle with present needs instead of simply using the largest spending year or assuming that every former expense must continue unchanged.
Examine the supported spouse’s realistic earning capacity
A 20-year marriage can end when both spouses are in their forties, when they are near retirement, or later. The length alone does not establish employability. Age, health, credentials, work history, and current opportunities need separate consideration.
Section 4320 expressly addresses earning-capacity impairment caused by domestic duties and contributions to the other spouse’s career. If one spouse left employment for many years, explain the current effect: obsolete skills, licensing requirements, training needs, and realistic wages after reentry.
The analysis should also recognize usable skills and actual opportunities. A vocational evaluation may help resolve a material dispute. The goal is a supported assessment of present and future capacity, not an assumption that a long marriage either eliminates work expectations or makes immediate full-time employment feasible.
Retirement changes the evidence; it does not supply an automatic cutoff
An existing support obligation does not automatically end when the payer reaches age 65. A legitimate retirement may support a modification request, but the court must examine the circumstances, remaining resources, and the agreement or order.
In re Marriage of Reynolds (1998) 63 Cal.App.4th 1373 addresses the treatment of retirement-age employment expectations. The case should not be read as erasing support whenever wages stop. Pension payments, investment income, assets, and the supported spouse’s situation can remain important.
Our retirement article explains the distinction between retiring from work and terminating support. For planning purposes, assemble pension estimates, expected benefits, investment information, and a realistic postretirement budget before negotiating a permanent cutoff.
Property division and support should be evaluated together
The assets each spouse receives can affect income, housing costs, liquidity, and financial security. A retirement account, a home, and an investment account with the same stated value may have very different practical uses and tax consequences.
Section 4320(e) requires consideration of obligations and assets, including separate property. That does not mean property division automatically replaces support or that every asset must be consumed before support is available. The legal treatment depends on the circumstances and relevant authority.
Explain how the property will actually function. Will it generate income? Will it reduce housing expense? Is access restricted? What liabilities or taxes accompany it? A settlement comparison should use those facts rather than treat all account balances as immediately spendable cash.
Health and insurance deserve a concrete financial plan
Age and health are express statutory factors. Medical limitations may affect employment, expenses, and the time available to build independent income. Present relevant evidence of functional limitations and costs rather than relying solely on a diagnosis or a general claim of poor health.
Health-insurance costs after divorce can differ from those during marriage. Identify available coverage, premiums, deductibles, and other expected expenses using current information appropriate to the individual situation. Do not assume the former employer’s family coverage will continue on the same terms.
The support request should explain how those expenses fit the budget and the other spouse’s ability to pay. A settlement may address insurance-related obligations, but the terms need to be clear about responsibility, duration, and what happens if coverage changes.
A jurisdictional cutoff should not rest on an unsupported forecast
In re Marriage of Morrison (1978) 20 Cal.3d 437 cautions against ending support jurisdiction after a lengthy marriage based on speculation that the supported spouse will become self-supporting. The consequence of a cutoff can be much more serious than a reduction in the current payment.
Distinguish a review date, a step-down, termination of payments, and termination of jurisdiction. They allocate future risk differently. A review provision may allow the court to examine actual circumstances later; a final jurisdictional termination may foreclose that opportunity.
If the parties agree to finality in exchange for property or a lump sum, evaluate the bargain explicitly. Our buyout article addresses the assumptions and risks that should be examined before trading future support rights for a present payment.
Address the risk of death separately from ordinary payment duration
Under section 4337, support ordinarily terminates on either party’s death or the supported spouse’s remarriage unless the parties otherwise agree in writing. A long marriage does not remove that rule.
Section 4360 separately permits certain protective arrangements, including appropriate insurance, annuity, or trust provisions, where just and reasonable under the statutory framework. Such arrangements should not be confused with assuming that ordinary monthly support automatically continues after death.
If security is proposed, examine availability, cost, ownership, beneficiary terms, proof of maintenance, and the relationship to the support obligation. A requirement that cannot be administered or verified may provide less protection than the parties expect.
Build a settlement around current evidence and future contingencies
Evaluate the proposed monthly amount, variable-income provisions, retirement assumptions, tax treatment, modification rights, termination events, and jurisdiction. Compare the effect on both households under realistic circumstances.
Where the future remains uncertain, identify which risks each spouse will bear. A nonmodifiable agreement can provide predictability while limiting relief if health or finances change. An order subject to later modification preserves flexibility but can require future proceedings.
After a 20-year marriage, careful drafting matters as much as the initial amount. The agreement should reflect the evidence and the parties’ informed choices about the years ahead.
