If you are reviewing a proposed divorce settlement, the items most often missed are the retirement-division order, the formula for splitting unvested stock options and RSUs, responsibility for joint tax years, debts that creditors can still collect from you, insurance coverage after judgment, and the valuation and buyout terms for a business.

Most people searching for this in San Diego County are not starting from zero. There is usually a draft marital settlement agreement already on the table. Perhaps a spouse's attorney prepared it, or a mediator did, and a signing date is approaching. The document looks finished. Something still feels off. You may be a founder in Sorrento Valley, an executive with equity vesting over the next four years, or the spouse who never handled the brokerage statements. Either way, you want to know what a careful reader would catch before the agreement becomes a judgment of the San Diego Superior Court.

This page walks through each category the way a complex-asset review does. It starts with the asset or entity. Then it looks at who owns it and how. Then it asks whether it is community or separate, what it is worth, whether it can be traced, and what the agreement has to say to divide it cleanly.

What California Divorce Agreements Are Actually Required to Divide

Cal. Fam. Code § 760 is the starting point. It provides that, except as otherwise provided by statute, all property acquired by a married person during the marriage while domiciled in California is community property. That covers real or personal property, wherever it is located. A marital settlement agreement (MSA) is the contract in which spouses decide how that community estate is split. It is usually incorporated into the court's judgment.

The court's job and the parties' job are different. The court needs every community asset and liability to be accounted for and divided. The parties need an agreement that actually works after the judgment is entered. That means the plan administrator can act on it, the IRS situation is clear, and a buyout can be enforced. Many drafts meet the first standard on paper and fail the second in practice.

Silence does not make an asset disappear. Under Cal. Fam. Code § 2556, the court keeps continuing jurisdiction over community assets and liabilities the judgment never adjudicated. Either party can file a postjudgment motion to have them divided. The court then divides the omitted item equally, unless it finds good cause that the interests of justice require an unequal division. In practice, a forgotten account can mean returning to the Family Law Division of the San Diego Superior Court years later. By then the documents are harder to find and the value may have changed a great deal.

Retirement Accounts and Pension Benefits

Retirement assets are the category most frequently mishandled. Defined contribution plans, such as a 401(k) or 403(b), are community property to the extent contributions were made during the marriage. So is a defined benefit pension, which pays a monthly amount at retirement based on a formula. Tracing matters here. A balance that existed before the wedding, along with its growth, may be separate property. Contributions made after the date of separation are also generally separate.

The MSA alone does not divide a retirement account. For plans governed by ERISA, the federal law covering most private employer plans, a Qualified Domestic Relations Order (QDRO) is required. A QDRO is a separate court order directing the plan administrator to pay part of the benefit to the former spouse. State and public plans, including CalPERS and CalSTRS, use a Domestic Relations Order (DRO) in their own required format. Each order must be drafted to the plan's rules, pre-approved by the plan where the plan allows it, and entered by the court. Only after all three steps is the division real. The California Courts self-help site at selfhelp.courts.ca.gov explains the process in general terms. The drafting itself is plan-specific technical work, not a form to fill in.

Survivor benefits are the provision most often missed within this category. If the order does not preserve a survivor election, the former spouse's interest in a pension can end entirely when the participant dies. The broader issues are covered in more depth on this site's page on pension plans in divorce.

San Diego County also has a large military population at Naval Base San Diego, MCAS Miramar, and nearby Camp Pendleton. Military retired pay is divided under the Uniformed Services Former Spouses' Protection Act (USFSPA), 10 U.S.C. § 1408, which has its own rules. Cases involving service members from Naval Base San Diego or MCAS Miramar need attention to those rules and are not handled like civilian plans.

Stock Options, RSUs, and Deferred Compensation

In re Marriage of Hug, 154 Cal.App.3d 780, is the California case most often cited for the time-rule approach to equity compensation. A stock option is a right to buy company shares at a fixed price. A restricted stock unit (RSU) is a promise to deliver shares once a vesting condition is met, usually continued employment. When a grant is made during the marriage but vests after separation, part of it is typically community property and part is separate.

The time rule, in the form it is commonly applied, works like this:

Community interest = (months from grant to date of separation) ÷ (months from grant to vesting) × total shares in the tranche

A tranche is a batch of shares that vests on a single date. Executive packages at San Diego biotech firms in Torrey Pines and Sorrento Valley, or at defense and technology companies across the county, often include several grants, each with a staggered schedule. Each tranche needs its own calculation. A single four-year RSU grant with quarterly vesting can produce sixteen separate fractions.

Non-qualified deferred compensation follows similar apportionment logic. That includes compensation earned now but paid later, outside a tax-qualified retirement plan. The same is true of non-qualified stock options, which are taxed differently from incentive stock options.

A clause that divides "all stock options equally" leaves the division open to dispute. It does not say which grants are covered, when each vests, what formula applies, or who pays the tax when shares are sold. An agreement that can be enforced lists each grant by date and schedule and states the method. The site's page on stock options in divorce goes further into exercise, holding, and tax mechanics.

Tax Liabilities, Refunds, and Indemnification

Joint tax returns filed during the marriage create joint and several liability. That means the IRS can collect the full balance for a joint year from either spouse. Whatever the MSA says about who owes it binds only the spouses, not the IRS. For a household where one spouse ran a business, took aggressive deductions, or received complex compensation, this exposure can outlast the marriage by years.

A careful agreement addresses three things for every jointly filed year:

  • Allocation of liability for any deficiency, penalty, or interest later assessed.
  • Refunds, and who receives any refund or overpayment credit applied to a later year.
  • Indemnification, meaning a promise by one spouse to cover the other if the first spouse's tax obligation is collected from the second.

Innocent spouse relief under IRC § 6015 can relieve a spouse of joint liability in some situations. It requires a separate application to the IRS, has its own standards, and the IRS grants it only when those standards are met. It is a backstop, not a plan.

Capital gains are the other common gap. Two assets can carry the same market value and very different tax costs. A Mission Hills rental with a low basis is one example; a brokerage account concentrated in one low-basis stock is another. Basis is the original cost used to measure gain. The agreement can state who bears the embedded gain, and whether the value used for division is adjusted for it. The California Franchise Tax Board treats most of these issues much as the IRS does, but state tax is a separate liability. The FTB's guidance is at ftb.ca.gov.

Debt Allocation and Creditor Exposure

Cal. Fam. Code § 916 explains why assigning a debt in the MSA is not the same as getting rid of it. After the division, a spouse's separate property and the property that spouse received remain liable for debts that spouse incurred. That liability continues whether or not the agreement assigned the debt to the other spouse. A lender was not a party to the divorce and is not bound by how the spouses split the bills. Separately, anyone who co-signed a loan or holds a joint account remains contractually liable to that lender on their own signature.

The debts most often missing from San Diego County agreements include:

  • Home equity lines of credit (HELOCs) against the family home or a second home in Coronado or Del Mar
  • Business loans carrying one spouse's personal guarantee
  • Federal or state tax liens
  • Student loans taken out during the marriage
  • Balances on jointly held credit cards

Two tools address the gap, and they work differently. An indemnification and hold-harmless clause gives one spouse a contractual remedy against the other if the assigned debt goes unpaid. Section 916(b) also provides a reimbursement right, with interest at the legal rate and reasonable attorney's fees, when one spouse's property is used to pay a debt assigned to the other. Neither one stops the creditor. The only way to fully remove a spouse from a joint obligation is to refinance it into the other spouse's name alone. A business-owner spouse's personal guarantees are the item left out most often, because they rarely appear on a household balance sheet. They tend to surface only in the company's loan documents.

Health Insurance, Life Insurance, and Benefit Coverage

When the judgment is entered, a spouse covered under the other's employer health plan loses eligibility. That date is often set months after the parties stopped living together. Federal COBRA law generally lets the former spouse continue the same coverage for up to 36 months. The election must be made within 60 days. A spouse carrying these decisions alongside everything else can easily let that window pass.

The agreement can state who pays COBRA premiums during any support period. It can also say what happens if the covered spouse takes a job that offers its own benefits.

Life insurance is the security behind a support order. When spousal or child support is ordered, a clear agreement states four things: the amount of coverage the paying spouse keeps, how long it must stay in place, who is named as beneficiary, and how compliance is verified, usually by an annual statement from the carrier. A clause that says only "maintain adequate insurance" is difficult to enforce.

Disability coverage that replaces income can be a community asset to the extent premiums were paid with community funds. The California Supreme Court discussed this in In re Marriage of Elfmont, 9 Cal.4th 1026. Long-term care policies, with their cash value or conversion rights, are also frequently left out entirely.

Business Interests and Professional Practices

A business owner whose company grew during the marriage faces the most layered version of the chain this page follows. For an entity started before the marriage, the community's claim is often measured by the growth in value between the date of marriage and the date of separation. How much of that growth belongs to the community is a separate question that can call for forensic accounting. For an entity formed during the marriage, the starting presumption under § 760 covers the whole interest.

Valuation usually rests on one or more of three approaches:

  • Income approach — the value of expected future earnings, reduced to present value.
  • Market approach — comparison to sales of similar businesses.
  • Asset approach — the value of what the company owns, minus what it owes.

A well-drafted MSA names the method used and attaches or references the valuation report. Otherwise, a later dispute starts with no agreed baseline.

Goodwill is the value of a business beyond its tangible assets. In re Marriage of Lopez, 38 Cal.App.3d 93, set out factors California courts use to value goodwill in a practice built during the marriage. The key distinction is this. Goodwill that belongs to the business, such as its name, systems, client base, and staff, is generally treated as a divisible community asset. Value that exists only as the owner's future ability to earn is not divided. Where that line falls, for a La Jolla medical practice or a defense-contracting firm near Kearny Mesa, is often the largest single number in the case.

The agreement then has to answer several practical questions:

  • Who keeps the business?
  • How is the other spouse bought out?
  • What is the payment schedule, and what security backs it?
  • What happens if the company is sold soon after judgment?

Operating agreements, shareholder agreements, and buy-sell agreements can restrict transfers or set valuation formulas of their own. Those documents need to be reviewed before the MSA is signed. This site's page on divorce as a business owner covers the operating side in more detail. San Diego County's concentration of closely held biotech, defense, and real estate companies makes this one of the most frequent issues in local high-asset cases.

How the Firm Reviews Proposed Agreements

A review at High Net Worth Divorce Attorneys begins with inventory, not the draft itself. The first step is a list of every account, entity, policy, grant, and debt, built from source documents. Those include brokerage and plan statements, equity award agreements, K-1s, loan files, tax returns, and entity governing documents. Only then is the draft read against that list.

The review then moves through the same chain this page follows:

  1. Presumption check. Each item is tested against § 760, and any separate-property claim is examined for tracing support.
  2. Category review. Retirement, equity, tax, debt, benefits, business interests, and real property are each checked for a specific, workable provision. Concentrated stock, trust distributions, collections such as art and coins, and holdings like offshore accounts are included where they exist.
  3. Order review. Any proposed QDRO or DRO language is compared against the plan's requirements and the survivor-benefit terms.
  4. Enforcement read. Each clause is read as the court would read it at a later hearing.

Judgments in these cases are entered through the San Diego Superior Court's Family Law Division, including the Central Division at 1100 Union Street in downtown San Diego. A clause that seems clear at signing gets tested there if it later turns out to be ambiguous. The review often also looks at whether an existing prenuptial agreement changes how a category is characterized.

The firm's limits are part of the process. This practice focuses on divorces involving significant assets and complex financial structures, such as private companies, equity compensation, real estate portfolios, and trusts. Couples with a modest estate and a straightforward division are usually better served elsewhere. The San Diego Superior Court's self-help resources at sdcourt.ca.gov are a good place to start. The firm also does not take on emergency custody litigation or standalone military pension matters as a core service.

Frequently asked questions

What are the most common mistakes people make in divorce agreements? The most common mistakes fall into five groups. The first is dividing a retirement account without a QDRO or DRO. The second is splitting stock options or RSUs without grant dates and a formula. The third is leaving joint tax years without an indemnification clause. The fourth is assigning debts without refinancing or reimbursement protection. The fifth is overlooking the health and life insurance gap that opens once the judgment is entered.

What should not be forgotten in a divorce agreement? A useful checklist of categories includes retirement division orders and survivor benefits, and stock options, RSUs, and deferred compensation. It also covers tax refunds and liabilities for joint years, debt allocation with indemnification, and health, life, and disability coverage. Finally, it includes business valuations and buyout terms.

Does a divorce agreement bind creditors? No. A creditor was not a party to the divorce. Under Cal. Fam. Code § 916, the spouse who incurred a debt generally remains liable for it even if the agreement assigns it to the other spouse. Co-signers also remain liable on their own contract with the lender. An indemnification clause gives the spouses a remedy against each other, not protection from the creditor.

What happens to assets that are left out of a divorce agreement? An omitted community asset remains undivided community property. Under Cal. Fam. Code § 2556, either party can file a postjudgment motion asking the court to divide it. The court generally divides it equally. This can mean new litigation years after the divorce is final.

Do I need a separate order to divide a retirement account in California? Yes. The settlement agreement alone does not divide a retirement account. A Domestic Relations Order is required, or a Qualified Domestic Relations Order for ERISA plans. It must be drafted to the plan's rules, accepted by the plan administrator, and entered by the court. General information is available at selfhelp.courts.ca.gov.

How are stock options divided in a California divorce? Courts commonly use the time-rule approach associated with In re Marriage of Hug. The community's share reflects the portion of each grant's vesting period that fell within the marriage, before separation. Each tranche is calculated separately. For that reason, a general reference to "all stock options" is not enough to make the division enforceable.

What is the difference between enterprise goodwill and personal goodwill in a California divorce? Enterprise goodwill is value that belongs to the business itself, such as its name, systems, and client base. Built during the marriage, it is generally divisible community property. Value that exists only as an owner's future earning capacity is not divided. Where that line falls is fact-specific, and the agreement can record how it was treated.

Where are San Diego County divorce cases filed? Divorce cases are filed in the Family Law Division of the San Diego Superior Court. The Central Division is at 1100 Union Street in San Diego. Current filing information, forms, and self-help resources are at sdcourt.ca.gov.

Before You Sign a San Diego Settlement

A settlement agreement is the last point at which an omission costs nothing to fix. Once it becomes a judgment, fixing a gap means a motion, a hearing, and sometimes a new valuation. In a document review with Amy J. Lass, you walk through your asset inventory against the draft, category by category. You leave with a written list of the omissions and ambiguous clauses, delivered before your signing deadline. If your estate turns out to be simpler than you feared, the review will say so, and the court's self-help center may be all the help you need.
