Does My Spouse Have a Claim to My Cryptocurrency in an Illinois Divorce?

 Posted on April 05, 2026 in Asset Division

If you own Bitcoin, Ethereum, or other digital assets, a divorce can raise some tough questions. You may be wondering whether your spouse has a right to your cryptocurrency, how it gets valued, or whether it can even be found if someone tries to hide it. In 2026, cryptocurrency is a common part of many people’s finances – according to the Pew Research Center, about 16 percent of U.S. adults have used or invested in cryptocurrency – and Illinois courts are now regularly dealing with digital assets in divorce cases. 

A St. Charles divorce attorney can help you understand how crypto fits into your case and what steps to take to protect yourself.

Is Cryptocurrency Considered Marital Property in an Illinois Divorce?

Under 750 ILCS 5/503, all property acquired during a marriage is presumed to be marital property. It does not matter whose name it is under. This applies to cryptocurrency just like it applies to a bank account or a house. If you bought Bitcoin with money earned during your marriage, or acquired digital assets while you were married, those holdings will likely be considered part of the marital estate.

There are exceptions. If you owned crypto before you got married and kept it separate from marital funds, it may qualify as non-marital property. If you received cryptocurrency as a gift or inheritance, it may also be protected. Problems can come up if you moved pre-marital crypto into a shared wallet or used marital money to buy more. A Kane County property division lawyer can help you figure out which of your holdings are at risk and build a strong case for protecting them.

How Do Illinois Courts Value Cryptocurrency in a Divorce?

Valuing cryptocurrency in a divorce is not simple. Prices can change a lot from one day to the next. A Bitcoin portfolio worth $200,000 when you file for divorce in January could be worth much more or much less by the time your divorce is done. 

Courts will generally look at the fair market value of the digital assets at or near the time of settlement or trial. Both spouses may agree on a specific date to use, or a judge may decide. Because prices move fast, timing really matters. Your attorney may suggest locking in a valuation date to protect your interests. Another option is for each spouse to receive a share of the crypto itself rather than a cash payout after the divorce is finalized. This avoids disputes over price swings that happened after the split.

What Happens if a Spouse Is Hiding Cryptocurrency During an Illinois Divorce?

Some people try to hide cryptocurrency during a divorce. They may store it in private digital wallets that leave no easy paper trail. But hiding marital assets is against Illinois law. If a spouse hides or wastes marital cryptocurrency, the court takes that into account when dividing property.

A forensic accountant can help uncover hidden crypto. These professionals look through tax returns, bank records, and public blockchain records to find transfers a spouse was hoping to keep secret. Some common warning signs that a spouse may be hiding crypto include:

• Unexplained transfers out of bank or investment accounts

• Cryptocurrency listed on past tax returns that suddenly disappears

• Transactions at known crypto exchanges show up in financial records

• A spouse who is unusually secretive about certain online accounts or devices

 If you think your spouse is hiding digital assets, tell your attorney right away.  In some cases, the court can order a spouse to turn over device passwords and account access as part of the discovery process. The sooner you raise the issue, the more options your legal team has to force disclosure.
