Crypto Valuation Date in Divorce: Why the Date Matters

The crypto valuation date decides the price in a divorce: when a divorce involves crypto, the price you use depends on the date you pick, and the date changes who pays whom. The arithmetic below uses assumed numbers. The encouraging part is that the date is a variable you can compute, discuss and put in writing before it becomes a dispute.

Why the Date Changes the Number (Worked Example)

These figures are assumed. Say the only marital asset is 2 Bitcoin, and Spouse A keeps it and buys out Spouse B with cash equal to half its value. If the agreement values it at $100,000 per coin, the asset is $200,000 and A owes $100,000. At $80,000 per coin A owes $80,000, and at $120,000 A owes $120,000.

Price per coin	Asset value	Buyout owed
$100,000	$200,000	$100,000
$80,000	$160,000	$80,000
$120,000	$240,000	$120,000

So in this simple setup, the keeper of the crypto owes less when the agreed price is lower, and the spouse being bought out receives more when it is higher. If the price has fallen since an earlier date, the keeper gains from a later date and the other spouse from the earlier one. If it has risen, the incentives reverse. This is my reading of the arithmetic, and real cases with other assets and other formulas will differ.

What the Valuation-Date Sources Say

A CBIZ article says the date used to value an asset changes the marital net worth and the equalization payment. It lists candidate dates including the date of legal separation, the date the action is filed, a date the parties agree on, the date of settlement, and the date of trial or distribution. In many states the court decides after hearing each side’s proposed date, and rules differ by jurisdiction. It describes passive assets that move with the market as most commonly valued at a current date such as trial or settlement, and active assets affected by the parties’ actions as valued closer to the breakdown of the marriage (CBIZ). In my reading, a coin held and left alone fits the passive description, while a position you actively trade or stake fits the active one.

The same article gives a volatile-asset example: a brokerage account worth $100,000 at filing falls to $50,000 by trial. If a filing-date value is fixed while distribution happens later, giving the whole account to one party overstates the division by $50,000, while splitting the account shares the loss and leaves the equalization payment unaffected (CBIZ). The same logic applies to crypto in my view.

A New Jersey law-firm blog says courts typically use market value on a specific date, such as the filing or hearing date, and notes that crypto’s volatility complicates valuation (Weinberger Law Group). That is one firm’s general description, not a statute.

Another Assumed Example: Filing Date vs. Trial Date

Using the same 2 Bitcoin, assume the price is $100,000 at filing and $80,000 at trial. A buyout at the filing price is 2 × $100,000 ÷ 2 = $100,000. At the trial price it is 2 × $80,000 ÷ 2 = $80,000. The date alone moves $20,000 between the spouses. These are assumed prices.

One State’s Default Date and Its Exit Ramp

State law can answer the date question before anyone argues it. California Family Code § 2552 says that, unless subdivision (b) applies, the court values community assets and liabilities as near as practicable to the time of trial. Subdivision (b) lets the court use a different date, but only if the moving party gives the other party 30 days’ notice, good cause is shown, the date falls after separation and before trial, and the purpose is an equal division of the community estate in an equitable manner. The court may use that date for all or only part of the assets (California Family Code § 2552). This is one state’s rule, and other states differ.

Run it through the 2 Bitcoin example. If the price was $100,000 per coin at separation and $80,000 at trial, the default trial-date value is 2 × $80,000 = $160,000 and the buyout is $80,000. An alternative separation-date value would be 2 × $100,000 = $200,000 and a $100,000 buyout, a $20,000 difference. Under the statute, getting from the first number to the second requires a motion with 30 days’ notice and a showing of good cause, so the default date is where the analysis starts. The prices are assumed.

That gives each spouse a plan. If you expect the default date to work against you, the statute’s notice requirement means you need to raise the issue early, with the price history and the reason, rather than at the hearing. If you would prefer certainty, the CBIZ article above lists a date the parties agree on as a candidate, and writing an agreed date, time and price source into the settlement removes the need for the motion. Either way, the useful move is to find your state’s default rule first and then compute both numbers.

Naming the Price Source (My Suggestion)

Prices differ by exchange and by time of day, so I’d suggest the agreement name the date, the time and the price source. An ABA committee article recommends valuing at a documented venue and timestamp, using the exchange where the asset was held or practically liquidated, since a generic spot price may not reflect realizable value, and considering factors such as spread, depth and fees for less liquid tokens (ABA Family Law Committee).

Coins or Dollars (My Reasoning)

A transfer defined in coins, such as “1 Bitcoin,” doesn’t need a price to carry it out. A transfer defined in dollars, such as “crypto worth $100,000,” needs a price at the moment of transfer, so the same question of date, time and source comes back. That follows from how the two are defined. The ABA committee article also reminds readers that transfers incident to divorce generally trigger no gain or loss and the recipient takes the transferor’s basis, so after-tax value belongs in the comparison (ABA Family Law Committee).

How to Get Started With the Crypto Valuation Date

Work out which direction the price has moved and which date helps you, using the arithmetic above.
Choose a date for each asset and document why. CBIZ advises choosing a valuation date for each asset and documenting the facts supporting it (CBIZ).
Name the date, time and source in the agreement. That is my suggestion.
Decide coins or dollars on purpose. Coins avoid a later pricing question; dollars need a fixed pricing method.
Keep a record of the price you used and where you got it.
Raise it with your attorney early, since the rules vary by state.

The Crypto Valuation Date: Questions Answered

Is there one best valuation date? No, going by the arithmetic above: which date helps you depends on the price direction and which side you are on.

Do stablecoins raise the same issue? My reasoning: a stablecoin is meant to hold a steady dollar value, so the date should matter far less. The ABA committee article does note that stablecoins can preserve dollar value while changing the asset’s form (ABA).

Who decides the date? CBIZ says in many states the court decides after hearing each side’s proposed date (CBIZ).

Where This Leaves You

The date is a negotiating variable with a dollar effect you can compute. Compute it first, then put the date, time and source in writing.
