Cryptocurrency and Divorce in Michigan: Finding, Valuing, and Dividing Digital Assets

Crypto Is No Longer a Fringe Asset

A decade ago, cryptocurrency was a niche interest. That is no longer the case. Roughly 40% of American adults under 40 own some form of cryptocurrency, according to recent surveys from the Federal Reserve and Pew Research. For millennials and Gen Z, a Coinbase account is as common as a savings account — and in many cases holds more money.

This shift has real consequences in divorce. Couples in their 20s, 30s, and early 40s are now splitting assets that include Bitcoin, Ethereum, Solana, stablecoins, staking rewards, DeFi positions, and NFTs. Many of these assets were acquired casually — a few hundred dollars here, a recurring buy there — and grew into portfolios worth tens or hundreds of thousands of dollars. In Oakland County divorces, where both spouses often have high incomes and investment accounts, crypto holdings are increasingly substantial.

The problem is that the legal system was not designed for assets that exist on a blockchain. Traditional discovery tools assume that assets are held by institutions — banks, brokerages, employers — that can be subpoenaed. Crypto can be held on a USB device in a desk drawer. If your attorney does not know how to find it, value it, and divide it, you may be leaving significant money on the table.

Why Cryptocurrency Is Easy to Hide — and How We Find It

Hiding a bank account is hard. Banks respond to subpoenas. They produce statements. They report balances to the IRS. Cryptocurrency, by contrast, can be:

• Self-custodied — held in a wallet on a phone, laptop, or hardware device like a Ledger or Trezor, with no institutional custodian
• Transferred pseudonymously — sent to another wallet address without using a name, Social Security number, or bank routing number
• Converted to privacy coins — moved into tokens like Monero that obscure transaction histories by design
• Held across dozens of wallets and chains — spread across Ethereum, Solana, Arbitrum, Base, and other networks that require separate investigation

A spouse who wants to conceal crypto has tools available that simply do not exist in traditional finance. But concealment is not the same as success. Here is how we approach it.

Centralized exchange subpoenas. Most people buy crypto through exchanges like Coinbase, Kraken, Gemini, or Binance.US. These companies are regulated, maintain account records, and respond to legal process. A subpoena to a centralized exchange produces account creation dates, deposit and withdrawal histories, current balances, linked bank accounts, and wallet addresses where funds were sent. This is often the starting point.

Tax return analysis. IRS Form 8949 requires reporting of crypto dispositions, and Form 1040 now asks directly whether the taxpayer received, sold, or exchanged digital assets. Reviewing tax returns — and comparing reported activity against exchange records — can reveal discrepancies that indicate undisclosed holdings.

Blockchain forensic tracing. When funds leave a centralized exchange and move to a self-custody wallet, the transaction is visible on the blockchain. Forensic analysts use tools like Chainalysis, CipherTrace, and Arkham Intelligence to trace the flow of funds across wallets, identify patterns, and connect addresses to real-world identities. A spouse who moves Bitcoin from Coinbase to a Ledger wallet has not hidden anything — they have created a traceable record.

Device and metadata analysis. Wallet applications on phones and computers leave traces — app installation records, browser history for DeFi platforms, seed phrase backups in notes or cloud storage. In cases involving significant suspected concealment, forensic examination of devices can uncover wallets that were never voluntarily disclosed.

How Cryptocurrency Is Valued in Divorce

Unlike a house that needs an appraisal or a business that requires expert valuation, crypto has a real-time market price. The challenge is choosing the right moment to fix that price.

Bitcoin's price can move 10-15% in a single week. Altcoins can double or collapse in days. This volatility creates a strategic question: what valuation date does the court use?

Michigan courts have discretion to choose a valuation date. Common options include:

• Date of filing — the date one spouse initiates the divorce
• Date of separation — when the parties physically or financially separated
• Date of trial or settlement — the most current value at the time of division

The date that benefits you depends on market conditions between filing and trial. If crypto has appreciated significantly since filing, the spouse retaining the crypto may prefer a filing-date valuation. If it has declined, they may prefer a trial-date valuation. Your attorney should be analyzing these dynamics and advocating for the date that protects your financial interests.

Types of Digital Assets That Must Be Disclosed

Many people think of crypto as just Bitcoin. In a modern divorce, the digital asset landscape is far broader:

• Bitcoin and Ethereum — the largest and most commonly held cryptocurrencies
• Altcoins — Solana, Cardano, Avalanche, and hundreds of smaller tokens
• Stablecoins — USDC, USDT, and DAI, pegged to the U.S. dollar and often used to park value without triggering taxable events
• Staking and yield positions — tokens locked in protocols earning interest or rewards
• DeFi liquidity positions — assets deposited into decentralized exchanges or lending protocols
• NFTs — non-fungible tokens that may hold significant value or may be nearly worthless
• Airdrops and token grants — tokens received for free based on prior protocol usage or employment
• Mining and staking rewards — income generated from validating blockchain transactions

Every one of these must be disclosed during discovery. Failure to disclose any asset — digital or traditional — can result in sanctions, contempt, adverse inferences, or the court reopening the divorce judgment after it is finalized.

What Happens When a Spouse Lies About Crypto

Courts take concealment seriously. A spouse who fails to disclose crypto holdings during discovery is committing fraud on the court. Michigan judges have broad discretion to:

• Draw adverse inferences — assume the undisclosed assets exist and are worth whatever the other party claims
• Hold the concealing spouse in contempt of court
• Award a disproportionate share of the marital estate to the honest spouse
• Reopen the divorce judgment if concealment is discovered after the case is closed

The risk of hiding crypto is not just that you might get caught. It is that getting caught can cost you far more than honest disclosure ever would have.
