Dividing Cryptocurrency and Stock Options in a Montana Divorce

Why Crypto and Stock Options Complicate Montana Property Division

Montana's all-property rule under MCA § 40-4-202 sweeps everything into the marital estate — including digital assets and equity compensation that didn't exist when most divorce statutes were written. The court can divide cryptocurrency, unvested stock options, RSUs, and other non-traditional assets just like it divides bank accounts and real estate.

The challenge isn't whether these assets are divisible. It's how to find them, value them, and structure a division that doesn't create avoidable tax consequences.

Cryptocurrency in the Marital Estate

Bitcoin, Ethereum, and other cryptocurrencies are property under Montana law. If either spouse holds crypto — whether on a centralized exchange like Coinbase, in a self-custody hardware wallet, or staked in a DeFi protocol — it is part of the all-property analysis and subject to disclosure and possible allocation.

Finding it. Crypto held on centralized exchanges may generate tax forms, depending on the exchange and transactions. Check Schedule D of recent returns for capital gains or losses from cryptocurrency transactions. Bank statements showing transfers to or from exchanges (Coinbase, Kraken, Gemini) can confirm the existence of accounts even if no tax form was issued.

Self-custodied crypto (hardware wallets, software wallets) is harder to trace because no intermediary generates tax documents. If you suspect your spouse holds crypto off-exchange, discovery requests for wallet addresses, seed phrases, and transaction history are appropriate. A forensic specialist can analyze blockchain transactions to trace holdings.

Valuing it. Cryptocurrency prices fluctuate dramatically. Montana courts have discretion to establish a reasonable value from competent evidence; a filing-date or trial-date valuation may be relevant depending on the case. Because prices can swing 10% or more in a single day, the agreement should specify the exact date and time used for valuation and the exchange rate source (CoinGecko, CoinMarketCap, or the exchange where the asset is held).

Tax consequences. Transferring crypto between spouses incident to divorce is tax-free under IRC § 1041 — the recipient takes the original cost basis. But when the recipient later sells, they owe capital gains tax on the difference between the sale price and the original purchase price. A spouse who receives $50,000 in Bitcoin with a cost basis of $5,000 faces a much larger tax bill than a spouse who receives $50,000 in cash. Factor the embedded tax liability into your equalization calculation.

DeFi and staking complications. Crypto staked in liquidity pools or yield-farming protocols generates income that must be reported and valued. NFTs (non-fungible tokens) and governance tokens are also marital property if acquired during the marriage. The valuation of illiquid tokens and NFTs requires careful analysis — use floor prices from reputable marketplaces and document the methodology.

Stock Options and RSUs

Equity compensation from an employer — stock options, restricted stock units (RSUs), and performance shares — presents a different set of challenges because much of the value may not yet be accessible.

Vested vs. unvested. Vested options and RSUs have a current market value and can be exercised or sold. They're straightforward to include in the property worksheet at their current value minus exercise price (for options) or current market price (for RSUs).

Unvested equity is more complex. Montana courts can and do include unvested stock options in the marital estate, but the division depends on when the grant was made:

• Granted during the marriage, vesting during marriage: A marital asset candidate, subject to the court's overall equitable-distribution analysis.
• Granted during the marriage, vesting after divorce: The marital share is typically determined using a coverture fraction — the portion of the vesting period that fell within the marriage. If a four-year vesting grant was made during the marriage and two years of vesting occur after the divorce, roughly half the grant is marital property.
• Granted before the marriage: Included in Montana's all-property analysis; the court may allocate it to the owning spouse, while appreciation and contributions during the marriage can affect the allocation.

Valuation methods. For publicly traded companies, stock options can be valued using the Black-Scholes model or the intrinsic value method (current stock price minus exercise price). For private companies with no public market, valuation requires the most recent 409A valuation or an independent appraisal.

RSUs are simpler — their value is the current stock price times the number of shares. But for unvested RSUs, the question is whether to value them now (at current market price, discounted for the risk of forfeiture if the employee leaves) or divide them "if, as, and when" they vest.

The "if, as, and when" approach. Instead of valuing unvested equity now and making an equalization payment, some couples agree to divide each tranche as it vests. The employee spouse notifies the other when a tranche vests and transfers their share at that time. This eliminates the risk of over- or under-valuing future equity, but it requires ongoing cooperation between ex-spouses and a detailed enforcement mechanism in the decree.

Practical Steps for Your Property Division

When cryptocurrency or equity compensation is part of your marital estate, add these steps to your property division process:

1. Request discovery early. Ask for complete exchange account statements, wallet addresses, vesting schedules, stock option agreements, and recent 409A valuations.
2. Agree on a valuation date and methodology before negotiating the split. Lock this down in writing.
3. Tax-adjust all values. If the current exercise value of a stock option is $100,000 and the exercise cost is $20,000, its pre-tax spread is $80,000; the after-tax value depends on the option type, timing, and applicable tax rates.
4. Draft the transfer mechanism into the MP-500. Specify how and when crypto will be transferred (direct wallet-to-wallet or through the exchange), and how unvested equity will be divided as it vests.
