How Digital Assets Are Found, Traced, Valued, and Divided
Most of what people believe about crypto in a divorce is wrong in one of two directions. Some assume it is invisible and doesn’t have to be disclosed. Others assume it is hopeless: if a spouse is hiding crypto, there is nothing anyone can do. Neither is true.
California treats crypto like any other property, the disclosure rules apply to it in full, and the trail it leaves is often better than the trail cash leaves. What makes crypto hard is the vocabulary, the speed, and the price swings. Here are six things worth knowing before you assume anything.
1. Crypto Is Ordinary Property, With Unusual Problems
There is no “crypto statute” in the Family Code. Bitcoin bought with paychecks during the marriage is still community property the same way investments in a brokerage account are, no matter whose name is on it (Fam. Code § 760). Coins you owned before the marriage, or received as a gift or inheritance, generally stay separate, along with their growth in value (Fam. Code § 770). The hard part is proving it. If separate and community money got mixed in the same wallet, the spouse claiming a separate share has the legal burden to trace it, transaction by transaction. If you owned crypto before you married, download those records now.
2. Where It Lives Decides How You Find It
Crypto on an exchange such as Coinbase or Kraken sits with a company that verified your spouse’s identity and keeps records. That company can be subpoenaed. Crypto in a self-custody wallet, especially one kept offline on a small hardware device or on a card with 12 or 24 words written on it, leaves no statement at all. In that case the evidence has to come from your spouse, their devices, the bank records showing where the money came from, and the blockchain itself. Almost every case involves both kinds.
3. Hiding It Costs More Than Sharing It
Both spouses must disclose every asset under penalty of perjury, and crypto is no exception. If a spouse conceals a community asset, the court can award the other spouse half of it plus attorney’s fees (Fam. Code § 1101(g)). If the hiding involved fraud, oppression, or malice, the court can award all of it (Fam. Code § 1101(h)). Moving community crypto out of sight after separation breaks the rules. There is no gray area. The red flags are usually ordinary ones: unexplained transfers to crypto platforms on a bank statement, a tax form showing digital asset activity, exchange emails, or a charge for a hardware wallet.
4. The Blockchain Leaves a Trail, But Someone Has to Read It
Every transfer on a public blockchain is recorded permanently. Addresses carry no names, so the real work is connecting an address to a person. A forensic accountant or blockchain analyst starts with the bank records showing dollars turning into crypto, uses the exchange’s records to identify your spouse’s addresses, follows the coins from there, and then ties the trail back to your spouse with devices, tax returns, and testimony. Tracing proves where money went. It does not, by itself, prove who controls a wallet today, so the strongest cases pair it with ordinary documents. It can be expensive, which is why some couples agree to share one neutral expert.
5. The Valuation Date Can Move the Number Dramatically
By default, the court values community assets as near as practicable to the time of trial (Fam. Code § 2552(a)), though it can choose an alternate date for good cause. With most assets that choice moves the numbers modestly. With crypto, the same holding can be worth very different amounts on the date of separation, six months later, and at trial. Couples who settle can agree on the date or an averaging period themselves, along with which exchange’s price to use and whether rewards count. Writing those details down heads off a common source of later disputes.
6. An “Equal” Split Can Hide a Tax Bill
Handing crypto to your spouse in a divorce is not a sale, so no one owes tax on the handoff. The tax comes later, when whoever holds the coins sells them, and it is based on what the coins originally cost, not what they were worth at divorce. Imagine two batches of bitcoin, each worth $100,000 today. One was bought years ago for $4,000 and the other recently for $60,000. Splitting them one each looks equal, but one spouse would owe tax on $96,000 of profit and the other on $40,000. The fix is usually to split each batch in half or to adjust the rest of the division, and to have a CPA review the numbers before you sign. (These figures are hypothetical.)

Talk to Someone Before You Move Anything
If you think crypto is part of your divorce, talk to an attorney before you move, sell, or log into anything. Moving assets during a case can violate the automatic restraining orders, and logging into an account you were never allowed to use can create its own problems. The first conversation is free.
