California’s AB 1052: What Crypto Holders Need to Know About Dormant Assets and More

California’s Assembly Bill 1052 (AB 1052) introduces a sweeping regulatory framework for digital assets, but for many crypto holders, the most immediate concern is how the law treats dormant custodial accounts. If you’re a California resident holding crypto on a centralized exchange, this law could directly affect your access to those assets. Withum’s Digital Currency and Blockchain Technology Services Team has broken down what you need to know and how to prepare.

What Is AB 1052?

AB 1052 is a comprehensive law that:

While the law touches on many areas, the dormant asset provision is especially important for long-term holders and estate planners.

Dormant Digital Assets: A New Category of Unclaimed Property

What Does “Dormant” Mean?

Under AB 1052, a custodial crypto account is considered dormant if there has been no user-initiated activity for three consecutive years. This includes:

Suppose the account meets these criteria and the user’s last known address is California. In that case, the custodian must report the account as unclaimed property and transfer the assets to the State Controller’s Office.

Who Is Affected?

Note: This law does not apply to self-custodied wallets or cold storage solutions.

Why This Matters for Crypto Holders

Many crypto investors follow a “HODL” strategy—buy and hold for the long term without frequent interaction. AB 1052 challenges this approach by introducing a legal risk to inactivity.

Even if you intend to hold indefinitely, the state may interpret prolonged silence as abandonment. This could result in temporary loss of access and a burdensome claims process to recover your assets.

How to Protect Your Crypto from Being Declared Dormant

Withum recommends the following proactive steps:

1. Review Your Custodial Accounts

Identify any accounts at risk of dormancy, especially those you rarely access.

2. Maintain Periodic Activity

Reset the dormancy clock by:

3. Document Ownership

Keep detailed records of your holdings, including:

This is especially important for estate planning and heirs needing to reclaim assets.

4. Consider Self-Custody

Moving your assets to a private wallet may be a better fit if you prefer to hold long-term without regular interaction. Self-custodied wallets are not subject to AB 1052.
