California has adopted clear, mandatory, and enforceable relinquishment requirements for individuals subject to civil and criminal domestic violence restraining orders and other civil protective orders, including civil and workplace harassment, elder abuse, and gun violence restraining orders. The state has also adopted a clear, mandatory, and enforceable relinquishment law to remove firearms from people convicted of or pending trial for serious firearm-prohibiting crimes.

For information on relinquishment when a court issues a domestic violence or other restraining order, see the Domestic Violence & Firearms in California page. For information on people disqualified from possessing firearms in California, see our Firearm Prohibitions in California page.

Relinquishment of Firearms by People Convicted of Firearm-Prohibiting Crimes

Prior to passage of a ballot initiative called Proposition 63 in 2016, California law had no clear mechanism to ensure people convicted of firearm-prohibiting crimes relinquished their guns after conviction.

In November 2016, California voters passed Proposition 63 to close this gap and made California the first state in the nation to require all people convicted of firearm-prohibiting crimes to provide verification to the courts that they sold or transferred their firearms after conviction. Since January 1, 2018, Proposition 63 has required courts to order people convicted of firearm-prohibiting felonies and other serious crimes to relinquish their firearms (through a third-party designee) and to provide these defendants with a standard Relinquishment Form at the time of conviction.1 The form among other things:

  • Informs defendants that they are required to relinquish all firearms within specified time periods by selling or transferring the firearms to a licensed firearms dealer, or by transferring them to local law enforcement.
  • Informs defendants that they are required to declare any firearms that they possessed at the time of conviction and to name a lawful, consenting designee or law enforcement agency to relinquish those firearms on the defendants’ behalf, if applicable.
  • Requires the defendant or designee to file the completed relinquishment form with the court-assigned probation officer, along with receipts from the law enforcement agency or licensed dealer who took possession of the defendant’s firearms, verifying that the offender relinquished all firearms prior to sentencing, as required.2

This law requires an assigned probation officer to notify the court and prosecuting attorney about whether the offender properly relinquished all firearms indicated on the relinquishment form or by California’s automated database of firearm sale records.3Courts are generally required to verify that relinquishment occurred before final disposition of the defendant’s case.4 If the court finds probable cause that the defendant failed to relinquish all firearms, as required, the court must either order the search for and removal of the defendant’s firearms at any location where the judge has probable cause to believe the defendant’s firearms are located, or upon good cause shown by the defendant, extend the time for providing proof of relinquishment for up to 14 days.5

This relinquishment process provides clear and mandatory procedures to people convicted of firearm-prohibiting crimes, expressly requires proof of relinquishment, and requires further enforcement action if they illegally retain weapons after conviction.

Relinquishment of Firearms by People with Severe Mental Health Impairments

California law requires law enforcement to temporarily remove weapons found to be under the possession or control of a person who has been detained or apprehended for examination of his or her mental condition, or who is prohibited from possession of firearms by reason of a mental disorder.6 Law enforcement must retain custody of these firearms, issue a receipt describing them to the individual, and notify the individual of the procedure for return of the firearm.7 Upon release from a mental health facility, the health facility personnel must notify the individual of the procedure for the return of a confiscated firearm.8 Health facility personnel also must notify the confiscating law enforcement agency of the release of the detained individual, and must document that the facility provided notice regarding the procedure for return of any confiscated firearm.9 California law also authorizes the issuance of a search warrant when the property to be seized includes a firearm owned by, or in the possession of, a person who has been detained for examination of his or her mental condition, or who is prohibited from possession of firearms by reason of a mental disorder.10

Recovering Illegally Owned Weapons – “APPS”

California law also requires the state Department of Justice (DOJ) to establish and maintain the Armed Prohibited Persons System (“APPS”),11 an electronic database identifying individuals who once legally purchased a firearm or registered an assault weapon but then subsequently became illegally armed by keeping those weapons after they became legally disqualified from possessing them under state or federal law. (This occurs, for example, when a gun owner is convicted of a domestic violence offense but fails to properly relinquish their firearms).12

California law requires the California Department of Justice, in conjunction with local law enforcement, to conduct enforcement actions to proactively recover and remove firearms from illegally armed individuals identified in APPS.13

The information contained in APPS can only be made available to certain entities–primarily law enforcement agencies–to actively identify people who are identified as unlawfully armed.14

In 2017 and 2018 alone, APPS enforcement efforts recovered nearly 6,000 illegally owned firearms, and hundreds of thousands of rounds of illegally owned ammunition.15
