Cryptocurrency (Bitcoin, Ethereum, stablecoins, NFTs, etc.) is subject to division in an Illinois divorce just like any other asset. Cryptocurrency does brings with it some unique practical headaches, however (how do you value it? how do you force disclosure when wallets are held under pseudonyms?). In Illinois, the legal framework that governs whether and how crypto is divided in a divorce is the Illinois Marriage and Dissolution of Marriage Act (IMDMA). If you on the path to divorce and you and/or your spouse has crypto assets, there are some practical considerations you need to be aware of.
Classification, Reimbursement, and Division of Cryptocurrency
The IMDMA (750 ILCS 5/503) sets the roadmap for property division in Illinois. Key rules you need to know include the following:
- Classification (what is marital vs. non-marital): Under section 5/503(a) and (b), property acquired by either spouse during the marriage is presumptively marital property. Property acquired before marriage, by gift, or inheritance may be non-marital. Same goes for crypto; if you acquire it before the marriage, it is likely non-marital and not subject to division in your divorce.
- Commingling and reimbursement: If non-marital property is mixed up with marital property such that its identity is lost, it may be transmuted to marital property; IMDMA section 5/503(c) provides for potential reimbursement to the contributing spouse, but only if they can trace their contribution with clear documentation.
- Division of marital property: Once property is classified as marital, section 5/503(d) requires the court to divide it equitably, which is not necessarily equally. The Court will consider the statutory factors (length of marriage, contributions, economic circumstances, etc.) in making this decision.
Applied to crypto, those rules mean: (1) crypto acquired during the marriage is presumptively marital, (2) crypto bought before the marriage may remain non-marital if it can be traced, and (3) if premarital crypto was commingled (e.g., transferred into joint accounts, or spent on marital property), it may lose its non-marital character unless you can trace it back to non-marital funds.
Practical Issues Unique to Cryptocurrency in Divorce
Cryptocurrency presents several practical complications that shape divorce litigation:
- Valuation date and volatility. Crypto prices swing widely. Parties and courts must agree (or litigate) whether value is set at petition filing, at trial, or some other date. Different valuation dates can lead to materially different awards.
- Disclosure and discoverability. Wallets on public blockchains may be held under aliases. The IMDMA’s financial disclosure obligations still apply to crypto, but full and complete discovery may require subpoenas to exchanges and forensic tracing is someone is trying to hide assets.
- Access and custody. Even if you know the cryptocurrency exists, it can be difficult to get to or transfer between spouses.
For these reasons, litigants often retain forensic accountants, blockchain analysts, and experienced family-law practitioners to identify, trace, and value cryptocurrency holdings and to craft remedies the court can enforce.
Discovery Tools and Remedies
Common steps and tools used in Illinois cases involving crypto include the following:
- Forensic accounting / blockchain analysis. Chain analysis can trace flows from wallet to wallet and to custodial exchanges, where subpoenas may be effective.
- Subpoenas and preservation requests to exchanges. Custodial platforms may preserve account records in response to subpoenas.
- Motions for sanctions / contempt. If a spouse refuses to disclose or destroys access to cryptocurrency, courts can impose sanctions, award an adverse division, or enter contempt sanctions.
- Temporary relief orders. Trial courts can issue injunctions or asset-preservation orders early in a case to prevent dissipation.
Case study: In re Marriage of Branson and Jorgenson, 2023 IL App (4th) 220547-U
A good practical illustration is the Appellate Court’s treatment of cryptocurrency in In re Marriage of Branson and Jorgenson. In Branson, the trial court classified, among other items, the cryptocurrency accounts Wife purchased during the marriage as marital property. On appeal, Wife argued that the classification was erroneous because she had used her own non-marital assets to buy the cryptocurrency.
The Appellate Court reviewed the record and affirmed the trial court’s ruling, reasoning that the cryptocurrency accounts were acquired during the marriage and Wife did not provide sufficient documentation tracing the crypto assets to her non-marital funds. The court expressly treated the cryptocurrency holdings under the ordinary IMDMA classification and commingling/reimbursement rules.
What Branson shows, practically:
- Courts will apply 750 ILCS 5/503 to crypto the same as to other assets, so time of acquisition matters and traceability is crucial.
- Where the record shows acquisition during the marriage and no clear tracing to pre-marital funds or gifts, appellate courts are unlikely to disturb a trial court’s classification of crypto as marital.
Cryptocurrency Strategy in Illinois Divorce
For spouses and attorneys facing crypto issues in Illinois divorces:
- If you hold crypto pre-marriage: preserve documentary evidence (purchase records, wallet addresses, exchange account records, account statements) to trace the asset’s origin and any intervening transfers. Clear, contemporaneous records are the best defense to a marital-classification argument.
- If you suspect hiding: seek subpoenas to exchanges and hire a blockchain forensic analyst.
- Negotiate valuation and offset terms: given volatility, consider mechanisms in settlement agreements that fix value or provide formulas for future appreciation/depreciation.
- Address custody and access: if coins are held in a hardware wallet, the settlement should address who will possess the device and who will hold seed phrases — and the agreement should provide remedies for refusal to transfer.
