How to value a stock portfolio for divorce settlement

Last updated 2026-07-11

What date do you use to value stocks in a divorce?

This is the single most consequential decision in the whole exercise, and the answer depends entirely on your state.

Most states fall into one of two camps. Community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin) generally treat the date of separation as the cutoff for what counts as marital property. Equitable distribution states, which is the majority, typically value assets at the date of trial or at the date of settlement, though many allow the parties to agree on a different date.

California Family Code Section 2552 states that the court "shall value the assets and liabilities that are to be divided as near as practicable to the time of trial." ^[1] Texas, another community property state, uses the date of divorce decree as the valuation date for most purposes. New York courts have discretion and often use the date of commencement of the divorce action.

Why does the date matter so much? A volatile stock can swing 30 to 50 percent in a single year. If the market dropped sharply between your separation date and your trial date, which party absorbs that loss depends entirely on which valuation date governs. If you're the spouse keeping the portfolio, you generally want the lower value to be the denominator. If you're the spouse receiving an offset in cash or other assets, you want the higher value.

The practical move: look up your state's default rule, then decide in your settlement agreement whether you want to lock in a specific date. Courts almost always honor a mutual agreement on valuation date. ^[2]

How do you find the actual value of a stock or brokerage account?

For publicly traded stocks, ETFs, and mutual funds, the market value on the chosen valuation date is your starting number. You pull the closing price on that date from the account statement, from the exchange's historical records, or from any financial data service. Brokerage statements are the simplest documentation. Most custodians (Fidelity, Vanguard, Schwab, and the rest) generate monthly and quarterly statements that show the account value as of the last trading day of the period.

If the valuation date falls mid-month, request a point-in-time statement or screenshot directly from the custodian's portal. Almost every major broker lets you download historical account summaries. Keep the PDF. Courts want contemporaneous documentation, not a printout you made after the fact from a web search.

Stock options and restricted stock units (RSUs) work differently. Unvested RSUs have a value (the current share price times the number of unvested shares), but courts handle the marital portion using a time-rule formula: you take the ratio of time the grant was outstanding during the marriage versus the total vesting period. Say a grant has a 4-year vesting schedule, 2 years of which happened during the marriage. Half the unvested shares may be treated as marital property. ^[3]

For a 401(k) or IRA holding mutual funds or target-date funds, the account statement works the same way. The dollar balance on the chosen date is the value. The complication is taxes, which gets its own section below.

Asset type	Where to get the value	Key document
Public stocks/ETFs	Brokerage statement or exchange history	Account statement PDF
Mutual funds	Brokerage statement (NAV × shares)	Account statement PDF
RSUs (unvested)	Share price × unvested shares × marital fraction	Grant agreement + pay stub
Stock options	Black-Scholes or intrinsic value; requires financial pro	Option agreement + current price
401(k) / IRA	Account statement balance	Quarterly statement
Employer stock (ESOP)	Plan administrator statement	ESOP statement

Do you need to account for taxes when valuing a stock portfolio?

Yes. Ignoring taxes is one of the most common and costly mistakes in DIY divorce property division.

A taxable brokerage account with a $200,000 market value is not equivalent to $200,000 in a savings account if $120,000 of that represents unrealized capital gains. When those shares eventually sell, the federal long-term capital gains tax rate is 0%, 15%, or 20% depending on income, plus the 3.8% Net Investment Income Tax (NIIT) for higher earners. ^[4] A couple in the 20% bracket plus NIIT owes 23.8% on that $120,000 gain, which is about $28,560. The real economic value of that account is closer to $171,000.

The same logic runs in reverse. A portfolio with embedded losses has more value than its market price suggests, because the losses can offset future gains.

Retirement accounts (401(k), traditional IRA) hold pre-tax money. When it comes out, it gets taxed as ordinary income. A $200,000 traditional IRA is not the same as a $200,000 Roth IRA. Courts differ on whether to apply a present-value tax discount to retirement accounts at settlement. Many use a rough 20 to 25 percent discount as a convention, though a forensic CPA or financial advisor can model the actual number.

The IRS has a plain-language explanation of capital gains rates and how basis works in IRS Publication 550. ^[4] If you and your spouse can agree on the tax adjustment math, you can write it directly into the settlement agreement. If you can't agree, a neutral CPA can run the numbers for a flat fee, often $300 to $800 for a straightforward portfolio.

The rule that saves people money: compare after-tax values, not gross account balances, when you offset one type of asset against another.

What is cost basis and why does it change what a stock is worth in divorce?

Cost basis is what you paid for a share (or what the IRS treats as your purchase price). When you sell, you owe capital gains tax only on the difference between the sale price and the basis.

In a divorce, basis matters because of a rule called "carry-over basis." Under IRC Section 1041, transfers of property between spouses incident to divorce are not taxable events. ^[5] That sounds great, but it means the receiving spouse takes the asset with the original (often low) basis. If your spouse bought Apple stock in 2005 at $5 a share and it's now $200 a share, whoever ends up with those shares inherits a big embedded tax bill.

To calculate the actual after-tax value: take the market price, subtract the cost basis per share to get the gain, multiply the gain by the expected capital gains rate, and subtract that tax from the market price. For a portfolio with mixed lots bought at different times (which most brokerage accounts have), you'll need the "cost basis" section of the brokerage statement. Most custodians show this in the "unrealized gain/loss" column.

If a brokerage account has $150,000 in market value and $50,000 in total cost basis, the embedded gain is $100,000. At a combined federal rate of 23.8%, the tax liability is $23,800. The economic value to compare against other marital assets is $126,200, not $150,000.

States also levy capital gains taxes. California taxes capital gains as ordinary income at up to 13.3%. New York adds up to 10.9%. Your state's rate goes into the calculation too. ^[6]

How do you divide a stock portfolio without selling everything?

You don't have to liquidate. Selling everything to split the cash is often the worst approach tax-wise.

The most common method for taxable brokerage accounts is an in-kind transfer. Each party receives a proportionate share of the actual securities. If you agree that each spouse gets 50% of a portfolio, the custodian moves half the shares to a new account in the other spouse's name. The transaction is tax-free under IRC Section 1041. ^[5] Both spouses then hold the shares with carry-over basis.

Retirement accounts use a different mechanism, and one that needs a specific legal document:

• 401(k), 403(b), and pension plans require a Qualified Domestic Relations Order (QDRO). A QDRO is a court order that tells the plan administrator to split the account. Without it, any direct withdrawal triggers taxes and a 10% early withdrawal penalty. The plan administrator's office (not the court) approves the QDRO language, and this step can take 30 to 90 days after the divorce is final. ^[7]

• IRAs do not require a QDRO. They use a simpler "transfer incident to divorce" process. You provide the custodian with a copy of your divorce decree and a letter of instruction. The IRS confirms this process in IRS Publication 590-A. ^[8]

For employer stock in an ESOP or deferred compensation plan, the rules depend on the specific plan documents. Check with HR or the plan administrator before you assume an in-kind transfer is available.

If one spouse is keeping the entire portfolio and the other is receiving an offset, you agree on a specific dollar value (after-tax) and then offset it with other marital assets of equal after-tax value. A vacation home might offset the brokerage account, but remember to account for the capital gain buried in the house too.

Getting the divorce papers right is where these details live. Every agreed valuation date, every tax adjustment, and every transfer instruction belongs in the marital settlement agreement.

Do you need a financial expert, or can you value the portfolio yourself?

For a simple portfolio of publicly traded stocks and mutual funds with clear account statements, you can do this yourself. The valuation is the account balance on the agreed date from the brokerage statement. Add up the cost basis from the same statement. Run the tax math with your expected rate. Write the numbers into your settlement agreement.

You need a professional when any of these are true:

1. The portfolio includes hard-to-value assets: private company stock, limited partnership interests, stock options with complex terms, or deferred compensation plans. 2. There's a dispute about whether assets are marital or separate property (say, shares inherited during the marriage in a state that treats inheritance as separate property). 3. The embedded tax liability is large enough that disagreeing on the right discount rate will move the settlement by tens of thousands of dollars. 4. One spouse ran a business and took stock compensation that's tangled up with the business valuation.

A Certified Divorce Financial Analyst (CDFA) or forensic CPA can value a portfolio and issue a written report. Fees typically run $1,500 to $5,000 for a moderately complex engagement, though cases with business equity go much higher. The American Academy of Matrimonial Lawyers keeps a directory. ^[9]

For straightforward uncontested divorces, skipping the expert and using the brokerage statement is reasonable and what most courts expect. If you and your spouse agree on the numbers, the court rarely second-guesses a detailed, documented settlement. DivorceClear's $149 document packet includes the marital settlement agreement template where you'd record these agreed values, for couples who've already worked out the numbers and just need the paperwork done.

If you do hire a divorce attorney, part of their job in a contested case is disputing your spouse's expert's assumptions, so understanding the math yourself is still worth the effort.

How does your state's property division law affect stock valuation?

The fundamental split is community property versus equitable distribution.

In the 9 community property states (AZ, CA, ID, LA, NV, NM, TX, WA, WI), assets acquired during the marriage belong equally to both spouses regardless of who bought them. Stocks purchased with marital income during the marriage split 50/50 unless a prenup says otherwise. Stocks one spouse owned before the marriage (or inherited during it) are generally separate property and not divided.

In the 41 equitable distribution states, "equitable" doesn't mean equal. Courts divide property in a way they consider fair, which can be 50/50 or 60/40 or some other split based on factors like each spouse's income, the length of the marriage, contributions to the marriage, and economic circumstances. ^[10]

The state rules also govern what happens when marital and separate property get mixed (called "commingling"). If a spouse had $50,000 in a brokerage account before marriage and contributed another $30,000 of marital wages into the same account, and the whole thing grew to $200,000, tracing the separate portion requires records of every contribution and a calculation of how market gains attach to each piece.

Most state court websites have self-help divorce guides that explain local valuation rules. The National Center for State Courts maintains links to all state court self-help pages. ^[2] Many state courts also have family law facilitators who answer procedural questions at no cost.

State type	Default valuation date	Division default	Notes
Community property (CA)	Date of separation	50/50	CA Fam. Code § 2552
Community property (TX)	Date of decree	"Just and right"	TX Fam. Code § 7.001
Equitable distribution (NY)	Date of commencement	Equitable (often ~50/50)	CPLR § 236(B)
Equitable distribution (FL)	Date of filing	Equal presumption	FL Stat. § 61.075

What if some stocks were owned before the marriage or were inherited?

Separate property generally stays with the spouse who owned it. But there are two traps.

First, if you owned 500 shares of a stock before you got married and those shares appreciated during the marriage, some states divide the appreciation. California keeps the entire pre-marital stock (and its growth) as separate property. Other states, like New York, may treat passive appreciation of separate property as separate, but active appreciation (where the other spouse contributed effort) as marital. The line is genuinely blurry in a lot of cases.

Second, commingling. If you moved pre-marital shares into a joint account, or reinvested dividends from separate property shares into the same account that also holds marital shares, you may have commingled the assets and turned separate property into marital property. Some states call this "transmutation." Careful records of which shares came from where are the only defense, and for DIY divorces, this is often where you should at least pay a CPA or attorney for a one-hour consultation.

Inherited stock is treated as separate property in almost every state, even if inherited during the marriage, as long as you keep it separate. ^[10] Deposit an inherited stock certificate into your sole-name brokerage account, leave it there, and it stays yours. Move it into a joint account and the analysis gets messier.

If you and your spouse agree that certain shares are separate property, say so explicitly in the settlement agreement. Something like: "The 500 shares of XYZ Corp. held in Spouse A's sole-name account, valued at $X as of [date], are confirmed as Spouse A's separate property and are not subject to division" is clear and gives the court nothing to question.

What documents do you need to gather before drafting your settlement?

Get these before you try to write any numbers into a settlement agreement:

Brokerage account statements for each account, going back to the date of marriage and showing the agreed valuation date balance. Monthly or quarterly statements work. Annual consolidated statements from custodians often include cost basis summaries.

Cost basis reports. Most custodians have a "tax documents" or "cost basis" section in the online portal. The IRS required brokers to track and report cost basis starting in 2011 for stocks, 2012 for mutual funds, and 2014 for bonds. ^[11] For shares bought before those dates, your records may be incomplete and you may need to reconstruct basis.

401(k) and IRA statements as of the valuation date. For a QDRO, you'll also need the plan's Summary Plan Description (SPD), which HR can provide. The SPD tells you what types of QDROs the plan accepts.

Option and RSU grant agreements if either spouse has equity compensation. These show the grant date, vesting schedule, strike price (for options), and total shares.

Tax returns for the last 3 years. Schedule D shows realized capital gains and any loss carryforwards that might offset future tax on the portfolio.

Prenuptial or postnuptial agreement, if one exists, since it may override state defaults entirely.

For an uncontested divorce, you and your spouse can exchange these voluntarily. In a contested divorce, they come through formal discovery. Either way, the documentation trail needs to support every number in the settlement agreement. Courts do not accept "we agreed it was worth about $80,000." They want a statement.

How do you write the agreed stock value into your divorce settlement agreement?

The marital settlement agreement (MSA) is the legal contract that records what you and your spouse agreed to divide. For a portfolio, it needs to answer four things: what is being divided, what it's worth as of what date, how it's being transferred, and who is responsible for any tax consequences.

A workable clause looks like this: "The joint brokerage account held at [Custodian], account ending in [XXXX], had a market value of $[amount] and an estimated federal capital gains tax liability of $[amount] as of [date]. The parties agree that Spouse A shall retain this account and its entire contents. In offset, Spouse A shall pay Spouse B $[after-tax-value] within [X] days of the entry of the decree."

For an in-kind split: "The parties shall direct [Custodian] to transfer 50% of each security position in account [XXXX], as measured by share count on [valuation date], to a new account in Spouse B's name within 30 days of the entry of the decree."

For retirement accounts, the MSA should say that a QDRO or IRA transfer letter will implement the division and that neither party is responsible for the other's tax obligations on their respective portion after the transfer.

Be specific. Vague MSAs get bounced by the court or create disputes during execution. State the account, state the custodian, state the date, state the value, state the mechanism of transfer.

If you're handling an uncontested divorce, DivorceClear's document packet includes an MSA template formatted for your state. The stock and investment property sections include the fields described above, so you're filling in numbers rather than drafting from a blank page.

For a broader look at how property and debt division interacts with everything else in your filing, a divorce lawyer consultation (even a flat-fee one-hour session) is worth considering when the portfolio is large or involves pre-marital assets.

What about stock in a private company or a closely held business?

This one is genuinely harder and almost always needs a professional.

Private company shares have no public market price. Valuing them takes one of three standard approaches used in business valuation:

1. Income approach: Value based on the present value of expected future cash flows (discounted cash flow analysis). 2. Market approach: Value based on comparable company transactions or multiples from the public market. 3. Asset approach: Value based on the net fair market value of business assets minus liabilities.

For a small business, a qualified business appraiser (look for a CVA or ABV credential) typically charges $3,000 to $10,000 or more. Courts expect a written report following IRS Revenue Ruling 59-60, which lays out the factors for fair market value of closely held stock. ^[12]

The other wrinkle is "goodwill." Many states distinguish between enterprise goodwill (value attached to the business that would survive a change of ownership) and personal goodwill (value attached to the specific owner's relationships and skill). Personal goodwill is often treated as separate property in states like Texas and California. Enterprise goodwill is marital. That distinction can shift a valuation by six figures.

If you're dealing with private company stock, the divorce attorney or CDFA conversation is not optional. This is one area where getting it wrong costs far more than the professional's fee.

Frequently asked questions

Can my spouse and I just agree on a stock value without a financial expert?

Yes, for publicly traded stocks with clear brokerage statements. If you both agree the account was worth $85,000 on a specific date and you document it with the official statement, courts generally accept that. You only need an expert when the portfolio includes private shares, stock options, or when you genuinely dispute the value or the marital fraction of inherited or pre-marital assets.

What happens if the stock price changes between our agreement and when the divorce is finalized?

It depends on what your settlement agreement says. If you locked in a specific dollar value on a specific date, market movement after that date is the new owner's gain or loss. If the agreement says shares transfer in-kind (by share count), both parties ride the market until the transfer completes. Locking in a dollar value is cleaner for cash offsets; in-kind transfers are better when you want to avoid tax-triggering events.

Is a 401(k) worth the same as a brokerage account with the same balance?

No. A traditional 401(k) is entirely pre-tax money. Every dollar you withdraw gets taxed as ordinary income, plus a 10% penalty if you're under 59.5. A $200,000 401(k) might net $140,000 to $160,000 after taxes. A Roth 401(k) or Roth IRA, where contributions were already taxed, is worth closer to its face value. Always compare after-tax values when offsetting retirement accounts against other assets.

Do I need a QDRO for every retirement account?

No. QDROs are required only for employer-sponsored plans governed by ERISA: 401(k), 403(b), and pension plans. IRAs use a simpler transfer incident to divorce process, requiring only your divorce decree and a letter to the custodian. Government plans (federal Thrift Savings Plan, state pension plans) have their own orders with different names and requirements. Check your specific plan's rules.

Can I keep the house and give my spouse the stock portfolio as an offset?

Yes, and this is one of the most common trades. The key is making sure the after-tax values are comparable. The house has its own embedded gain (the $500,000 exclusion for married couples under IRC Section 121 reduces but may not eliminate the tax). The stock portfolio has its own embedded gain. Work through the after-tax math on both assets before agreeing they're equivalent.

What if my spouse hid a brokerage account I didn't know about?

In a contested divorce, financial discovery (interrogatories, subpoenas to financial institutions) can surface hidden accounts. In an uncontested divorce, both spouses sign the settlement agreement under penalty of perjury, attesting they've disclosed all assets. If a hidden account surfaces after the decree, most courts allow the deceived spouse to reopen the settlement for fraud. Keep tax returns: brokerage 1099s show up there and are hard to hide.

How are stock dividends treated during the separation period?

In community property states, dividends earned before the date of separation on marital stock are generally marital property. Dividends earned after separation on separate property are separate. In equitable distribution states the analysis is similar but fact-specific. If dividends were reinvested (DRIP), the reinvested shares have their own purchase date and basis. Capture this in the account statement at the agreed valuation date.

What is the date of separation and how do I establish it?

The date of separation is typically when one spouse communicated an intent to end the marriage and the spouses began living separately. California courts use a "complete and final break" standard after In re Marriage of Davis (2015). Most states look at a combination of physical separation and intent. Keep documentation: a text or email from that date, a lease on a new apartment, anything that pins the date down, because it affects what assets and debts get classified as marital.

Do I owe taxes right now when I transfer stock to my spouse in the divorce?

No. Under IRC Section 1041, transfers of property to a spouse or former spouse incident to divorce are not taxable events. You don't recognize a gain or loss on the transfer. The receiving spouse takes your original cost basis (carry-over basis). Taxes become due only when that spouse eventually sells the shares. This is why carry-over basis matters so much: the tax bill travels with the stock.

What if some of my employer stock was vested before marriage and some during?

Courts use a time-rule (or coverture fraction) formula. Divide the months the grant was outstanding during the marriage by the total vesting period. That fraction of the shares is marital; the rest is separate. For example, a grant outstanding for 48 months total, 24 of which were during the marriage, means 50% is marital property. Apply this to each grant separately, since vesting schedules differ.

Should I sell stocks before filing to avoid fighting over them in the divorce?

This is risky and sometimes illegal. Most states impose automatic temporary restraining orders (ATROs) when a divorce is filed that freeze marital assets. Selling and moving money before filing could violate those orders or a court's later instruction. It also triggers capital gains tax. Talk to a professional before taking any action on marital assets once you've decided to divorce.

How does alimony interact with a stock portfolio settlement?

They're separate issues legally, but connected in practice. A large portfolio offset given to one spouse in lieu of a bigger share of liquid assets can reduce that spouse's alimony claim, since courts look at the receiving spouse's total financial picture. Some states treat investment income from the portfolio as income for alimony calculation purposes. See our overview of alimony for how courts calculate support alongside property division.

What if we can't agree on the value of the portfolio?

For a publicly traded portfolio, the disagreement is usually about which valuation date to use or how to adjust for taxes, not the raw market price. Narrow the dispute to the specific disagreement and get a neutral CPA to model both scenarios. If you genuinely can't agree, a mediator (typically $150 to $400 per hour) can usually resolve a valuation dispute in one or two sessions, far cheaper than litigation.
