Divorce always raises thorny questions of how to divide marital property. In most cases, the remedy is pretty straightforward, requiring a surgical split between the two parties’ assets — although you can’t do that with the family dog or aquarium. But if you thought deciding who gets the dog was complicated, here comes cryptocurrency.

With the crypto wealth accumulation phase still new within many households, and the recent sharp decline in digital assets including bitcoin and ether dinging the confidence of investors who had just seen record highs, the path forward is murky. But for many married Americans, the current price of crypto doesn’t even register as an issue. That’s because the assets are easily squirreled away from an unsuspecting spouse.

“In divorce cases, crypto is creating the same headaches we’ve long seen with offshore accounts, except now the assets can be moved instantly and invisibly,” said Mark Grabowski, professor of cyber law and digital ethics at Adelphi University and author of several books about cryptocurrencies. He added that the problem is that ownership isn’t determined by a name on an account — it’s determined by who holds the private keys.

“If one spouse controls the wallet, they effectively control the assets,” Grabowski said.

Lawyers now have to subpoena exchanges, trace transactions on the blockchain, and determine whether coins were purchased before or during the marriage.

“Without that transparency and given the lack of reporting standards, it’s easy for one spouse to hide or underreport holdings. Courts are still catching up,” Grabowski said.

In theory, though, a crypto divorce should work like any other. Renee Bauer, a divorce attorney who has dealt with crypto splits, says the biggest question couples fight about is simple on the surface: who gets the wallet?

“That question opens the door to a mess of complications that traditional property division never had to deal with,” Bauer said.

The first challenge is figuring out what actually exists.

“A retirement account comes with statements. A house has an address. Crypto may be sitting in an online exchange or in a hardware wallet that one spouse conveniently forgot to mention,” Bauer said.

Tracing it then becomes part detective work and part digital forensics. Once the digital asset is authenticated, hashing out custody comes next.

“Some spouses want to keep the digital wallet intact, especially if they are the one who managed it during the marriage, while others want a clean monetary split,” Bauer said.

Courts are still figuring out the best way to handle this.

“There is also the security piece. If one spouse hands over private keys, they are effectively turning over total control. If they refuse, the court has to decide how to enforce access,” Bauer said.

She recounts seeing one lawyer who didn’t know much about crypto try to give the other spouse credit for the value of the bitcoin in another asset, not recognizing it’s not so simple, nor fair.

“Many divorce lawyers are slow to catch up and don’t even ask for disclosure. In my state of Connecticut, there isn’t a spot for crypto specifically on the financial affidavits. And for some, that could mean missing a valuable asset if they aren’t looking for it,” Bauer said.

Crypto hunters, PIs of digital asset divorce era

One of the few companies that can help locate a missing asset is BlockSquared Forensics. Ryan Settles, founder and CEO of the Texas-based company, says that the need for his services has increased exponentially since he founded his company in 2023. BlockSquared is dedicated exclusively to the crypto aspects of family law and divorce.

If a spouse (generally women, Settles says) suspects their partner is hiding crypto, their attorney may call in BlockSquared, which does anything from simple asset verification to deep investigations, tracing crypto across continents and into the murky world of wallets and exchanges. Settles’ company will then present the spouse with a “storyboard” that traces and timestamps the movement of cryptocurrencies.

Investigating whether one spouse has crypto is becoming increasingly common, he says, “especially folks involved in high-net-worth divorces and individuals with high net worth.”

Ferreting out crypto in a divorce is only going to become more common. Settles noted that millennials hold the highest amount of crypto, and over the next six months, this age group will be approaching peak divorce years, converging with increased crypto holdings.

Another aspect Settles looks at is tax liability for the spouse, making sure that gets addressed during the divorce.

“There are a significant number of tax issues that most people, even attorneys, are not even familiar with,” Settles says, adding that the number of taxable events and reporting requirements from even a single transaction can come as a surprise to even the most seasoned litigators.

“Most attorneys don’t understand it, don’t understand the terminology. There is a whole lot of trust without verification going on,” Settles said.

Many of his cases involve wives who were not only unaware of their husband’s crypto dabbling, but when the assets are finally split, can be socked with a massive tax bill from capital gains.

“Unlike a savings account, the value of crypto can swing wildly in a single day,” Bauer said. “Selling crypto to divide proceeds can trigger capital gains. Holding it can trigger new arguments when value changes,” Bauer added.

Relatively relaxed Internal Revenue Service reporting requirements for crypto have not helped, though they are set to get stricter starting with the 2025 tax year.

“There are so many pieces. There are a lot of attorneys doing nod and smile and pretend to understand,” Settles said.

But companies like his are usually brought in only when there is a good suspicion of a spouse hiding significant crypto assets, he said. With a retainer fee of $9,000 and investigations that can cost $50,000, Settles says his services often cost more than an attorney.

Hard questions about crypto property splits

Roman Beck, a professor at Bentley University, where he directs the Crypto Ledger Lab, says that because this is a relatively new area, it’s best to look at it as courts not dividing the digital wallet but instead the assets the wallet controls.

“The law treats crypto much less exotically than people think. The starting point is simple: for tax and most property-law purposes, cryptocurrency is treated as property, not as money,” Beck said.

In divorce, that means bitcoin, ether, stablecoins, and NFTs acquired during the marriage are usually part of the marital estate, just like a brokerage account or a second home, with how that property is split depending on the state.

“Courts don’t split wallets, they split value,” Beck said.

The real legal question is not “Who gets the wallet?” he said, but ‘How do we allocate the economic value the wallet represents, and who is trusted with technical custody afterward?”

This leaves courts and lawyers to do one of three things: split the holdings on-chain, sell and split fiat, or offset with other assets.

“From a technical point of view, a wallet is just a set of private keys, often spread across hardware devices, mobile apps, or even seed phrases on a piece of paper. You cannot safely ‘share’ a hardware wallet or a private key after divorce,” Beck said.

Another wrinkle in a crypto divorce is the volatility of the underlying asset, with price swings in the currency making it more difficult for couples to agree on timing of a split, both as a couple and for the digital assets. In the past two months alone, bitcoin fell from a high over $126,000 to the low $80,000s, a 35% decline, and saw its year-to-date gains wiped out, with plenty of wild daily swings.

If couples are thinking rationally and not emotionally, among the simplest solutions would be splitting the wallet on a chain to create two wallets for each of the divorced partners so they can continue holding their share of cryptos, or drawing up a legal agreement that gives shares of a wallet to each party.

“They would not have to sell immediately,” Beck said.

However, often one party is not familiar with holding a wallet and thus not comfortable with that solution.

Similar to a house jointly owned which a divorcing couple may not want to bring to the market at a bad time, a couple could also agree to turn over crypto holdings to trusted third party to act as agent on behalf of both and to sell the crypto once the market has improved — once a certain agreed upon minimum value has been reached.

But Beck added that while from an economic and technical point of view there is no barrier preventing a divorcing couple from keeping crypto assets using any of these methods to allocate a legal percentage to each partner and delay liquidation until market conditions improved, both parties need to agree, and “most just want to be done,” he said.

Blockchain ledger transparency and the courts

One positive it that despite crypto’s reputation as a haven of anonymity, other aspects of digital assets work well for divorce proceedings.

“Public blockchains like bitcoin and ethereum are transparent ledgers. Every transaction is recorded forever. In other words, on-ledger data analytics turns the blockchain into a very patient financial witness,” Beck said. “That leaves a perfect audit trail if you know how to read the chain. … The real frontier isn’t the law, it’s the forensics,” he added.

Crypto’s adoption by many Americans — surveys in recent years from Gallup and Pew Research estimate that 14% to 17% of U.S. adults have owned cryptocurrency — is forcing family law to become more data-driven.

“The combination of transparent ledgers and powerful analytics gives lawyers and judges better tools to reconstruct financial behavior than they ever had with cash. The policy question going forward is not whether we can trace, but how far courts will go in requiring that level of scrutiny in everyday divorces,” Beck said.

Still, that doesn’t mean people won’t keep trying to hide assets. Settles says that often within 20 minutes he’ll see movement on the ledgers.

“They’ll start scrambling their assets, moving things, hiding things, moving them to tumblers. It’s quite fascinating,” Settles said.

And traceable.
