Dividing Cryptocurrency in Divorce: Marital Property in Ukraine

Cryptocurrency acquired during a marriage is, as a rule, jointly owned marital property, and it is subject to division. The difficulty is not one of law but of proof: crypto is easy to hide behind a pseudonymous address, so the real questions in a divorce are whether the asset can be shown to exist, whether it belongs to one spouse, and what the share is worth.

Cryptocurrency as marital property: what the Family Code says

Ukrainian family law does not name cryptocurrency, and it need not. Dedicated regulation of virtual assets is still taking shape, so crypto is divided under the general rules of the Family Code of Ukraine (Simeynyi Kodeks, SK). The key construct — joint matrimonial property of the spouses — covers any property and income acquired during the marriage, whatever its form.

• Article 60 of the SK sets a presumption: property acquired during the marriage belongs to both spouses jointly, even if registered in the name of only one. Cryptocurrency bought during the marriage falls under this rule.
• Article 61 of the SK makes the object of such ownership any property not excluded by law from civil circulation. Virtual assets fit here as an asset with value.
• Articles 69–71 of the SK govern the division: each spouse’s right to divide, the default equality of shares (Article 70), and the methods — in kind or by compensation for a share (Article 71).

So “the wallet and the exchange account are in my name, so it is mine” does not work legally. Under the Article 60 presumption, an asset acquired during the marriage is joint until the contrary is proven.

When crypto is not divided: personal private property

There is an important exception. Under Article 57 of the SK, personal private property includes property acquired before the marriage, and property received during it by inheritance, as a gift, or bought with personal funds. Cryptocurrency will therefore not be divided if it was:

• acquired before the marriage was registered — appreciation during the marriage alone does not make it joint;
• received as a gift or by inheritance personally by one spouse;
• bought with personal funds, for example money from a pre-marital apartment.

But the burden of proof shifts: a spouse who claims the crypto is personal must substantiate the source of the funds and the date of acquisition. A bare assertion is not enough.

The core problem: proving existence and ownership

Unlike real estate or a car, cryptocurrency has no state register of owners — no database the court can query for someone’s holdings. So the dispute comes down to two tasks.

1. Prove the asset exists at all

The other spouse often does not know how much crypto there is or where it sits. Existence is proven by indirect data: exchange fund movements, traces in correspondence, documents, and testimony. A single undeclared cold wallet may go unfound — but the entry into crypto through a bank or exchange almost always leaves traces.

2. Prove the wallet belongs to a specific person

A public blockchain address is pseudonymous — on its own it carries no name. It is tied to a spouse at the points where crypto touches the real world: the bank account the money came from, KYC identification on the platform, devices, correspondence. Proof of ownership is built here.

How hidden cryptocurrency is uncovered

In my expert practice, the weakest link for anyone hiding assets is the “money to crypto” transition. The main sources:

Source	What it yields
Bank statements	Transfers to crypto exchanges and on-ramps — a direct trace of entry into crypto, with amounts and dates
Exchange KYC data	The account holder’s identity, buy/sell history, linked cards and wallets — by court request to the platform
Tax declaration	Declared crypto income appears in the property and income declaration filed with the State Tax Service (DPS); public officials must also e-declare virtual assets
Correspondence and devices	Screenshots of wallets, seed phrases, emails from exchanges, transaction alerts — evidence in a civil case
Blockchain analysis	Clustering of addresses, tracing transfers between wallets, linking an address to an identified account

A few practical caveats:

• Access is only through procedural means. In a civil case, information covered by bank secrecy or held by an exchange is obtained by the court at a party’s motion, under the Civil Procedure Code of Ukraine (Tsyvilnyi Protsesualnyi Kodeks, CPC) rules on the recovery of evidence. “Hacking” the other spouse’s account or obtaining data outside the law is not an option — the court will reject it.
• A civil dispute is not a criminal proceeding. Requests from the Bureau of Economic Security (BEB) or analytics from the State Financial Monitoring Service belong to the criminal and anti-money-laundering sphere; in a property-division case a party relies on civil-procedure recovery of evidence, not on those bodies. Do not count on the state finding the crypto for you.
• Ukrainian and foreign platforms differ in reach. A court requests data directly from a Ukrainian virtual-asset service provider. Data from a foreign exchange is harder to get — through international legal assistance, rarely used in family disputes — which raises the value of a bank trace inside Ukraine.
• Pseudonymity is not anonymity. Every transaction is recorded in the blockchain forever, and at the point where crypto is exchanged for money, KYC kicks in. That defeats the bet on invisibility.

Valuing the share: as of what date

Cryptocurrency is extremely volatile, so the valuation date is not technical but decisive: the same quantity of tokens can be worth different amounts a week apart. Possible reference points are:

• the date the marriage was dissolved;
• the date the spouses actually stopped running a joint household;
• the date the court hears the case — Ukrainian case law usually fixes the value of joint property at this date.

With no single “official rate” for cryptocurrency, the value is taken from liquid-platform data on the chosen date, with the quotation source recorded. The court sets the date and methodology when appointing the expertise, and the expert calculates as of that date. So a motion should state up front as of what moment and by which source the asset is to be valued.

The role of forensic economic expertise

Once the dispute is in court, a forensic economic expertise establishes the economic facts. It is governed by the Law of Ukraine “On Forensic Expertise,” while the procedure is set out in the Instruction on the appointment and conduct of forensic expertises and expert examinations, approved by Order No. 53/5 of the Ministry of Justice of Ukraine. In a civil dispute the court appoints it under the CPC.

What the expert establishes in a case on dividing crypto:

1. The fact and circumstances of acquisition — whether purchase transactions took place, when, for what amounts, and from what sources the funds came (in particular, whether from the spouses’ joint bank account).
2. The movement of assets — deposits and withdrawals on exchanges, transfers between wallets, the link between blockchain addresses and identified accounts.
3. The value of the assets — a valuation as of the date set by the court at the liquid-market rate, and, if needed, the size of the share in money.

The boundary of the expert’s competence is fundamental:

• The expert describes economic facts (joint-account funds went to an exchange, the asset was acquired in a given period, its value is X) but does not decide the legal question of who owns the property and how to divide it — that is the exclusive prerogative of the court.
• The expert does not “establish the wallet owner” as a legal fact; the expert shows the economic connection, and the court makes the legal assessment, with regard to the Article 60 presumption and the other evidence.

It is most useful to bring in an expert early — to frame the questions and map out which evidence must be recovered through the court.

The typical mistake of someone hiding crypto

A bad-faith spouse’s common strategy is to “move everything into crypto and say nothing,” betting on anonymity. In practice it loses:

• The blockchain forgets nothing. The transaction history is public and immutable; withdrawing assets without a trace is almost impossible — moving them only lengthens the chain, which analysis reconstructs.
• The bank gives away the entry into crypto. Even if the wallet is hidden, the transfer to the exchange stays in the statement, and from there the court reaches the platform’s KYC data.
• Concealment works against the owner. A court may weigh the disposal of a joint asset without the other spouse’s consent, on the eve of division, against the one who hid it — up to departing from equal shares in the other’s favour, or awarding compensation.

In short, concealment usually backfires.

Practical guidance for the parties

• If you suspect hidden assets — do not gather evidence yourself outside the law; record the traces you have (correspondence, exchange names, mentions of wallets) and, through a lawyer, move for the court to recover statements and platform data.
• For the lawyer — put economic, not legal, questions to the expert; separately define the date and source of the valuation; check that the conclusion rests on verified transactions.
• If you owned crypto before the marriage or received it as a gift — keep proof of the source and date of acquisition in advance: those documents secure the asset as personal private property under Article 57 of the SK.

Dividing cryptocurrency in a divorce is not a quarrel about “invisible money” but painstaking work to prove the asset’s existence, its ownership, and its fair value. If, as a lawyer or a party to a dispute, you face such a question, a considered consultation and forensic economic expertise will help you build a position on facts, not assumptions. I would be glad to look at your situation within the bounds of my expert competence.
