California Search Warrants – 7 Key Things to Know

In California, a search warrant is issued by a judge and authorizes law enforcement to search a person, a residence, a vehicle, a place of business, or any other specified area suspected of containing evidence of illegal activity.

Here are five key things to know:

  1. Once police find the evidence they are seeking, the warrant allows them to seize it.
  2. Search warrants must be based on probable cause and cannnot be overly broad.
  3. Warrantless searches can be legal, such as if you consent or as incident to a lawful arrest.
  4. You can ask the court to disregard any evidence found through illegal searches.
  5. Search warrants are different from bench warrants and arrest warrants.
Type of Warrant Purpose Issued By Based On
Search Warrant To search a specific location for specific evidence of a crime. Judge or Magistrate Probable cause to believe evidence is present
Bench Warrant To arrest someone who failed to appear in court or comply with court orders. Judge Failure to appear in court or follow court orders
Arrest Warrant To arrest a person suspected of committing a crime. Judge or Magistrate Probable cause to believe someone committed a crime

judge signing a warrant

A judge issues and signs a search warrant.

1. Who can authorize a search warrant?

Although a search warrant is issued on behalf of the state (that is, by the prosecuting agency), the judge actually issues and signs it. 1 2 3 The purpose of having a judge issue the warrant instead of the police or a prosecutor is to ensure that a neutral, detached individual evaluates the circumstances of the criminal investigation. 4

Before the judge can sign off, two requirements must be met: The judge must reasonably believe

  1. that a misdemeanor or felony has been committed, and
  2. that evidence of that criminal case is likely to be found in the place(s) described in the search warrant. 5

If the facts presented in the warrant application are convincing, the judge must sign and issue the search warrant. 6

Also, we should clarify the distinction between search warrants and two other common types of warrants.

2. What are the search warrant requirements for police in California?

There are certain requirements that law enforcement must meet in order to obtain a search warrant in California. They must show probable cause that the locations to be searched contain evidence, instruments or fruits of criminal activity.

The following are examples of the types of grounds on which a California search warrant may be issued:

It should be noted that if the sought property is held by an attorney, doctor, psychotherapist, or member of the clergy, a special procedure will be held before that evidence may be seized. Even then, the attorney, doctor, therapist, or clergyman must be the individual suspected of engaging in the alleged criminal activity. 8

Before a judge issues a search warrant, they must have probable cause to do so.

Probable cause

Probable cause” is a legal phrase. It refers to a “reasonable” belief that criminal activity is taking (or has taken) place.

So before a judge issues a search warrant, they must have a reasonable belief that the person/property specifically described in the warrant application (otherwise known as an “affidavit“) will be found in the searched location. 9

Before finding that probable cause exists, the judge may question (under oath)

These affidavits may be written or oral, and presented in person, via the telephone, by fax, or even e-mail. 11 They also must contain the facts that establish the grounds for the application or the probable cause for believing that they exist.

Affidavits are under penalty of perjury. 12

3. Are there rules as to the use of informants?

Police routinely rely on information provided by informants. Informants are individuals who provide information about people, organizations, or activities to the police without the consent of those people or organizations.

That said, the judge must be informed of some of the facts that led the informant to their conclusion that there is alleged criminal activity. 13 A mere opinion that a person or property is involved in a crime is therefore insufficient without evidence to support it.

Since it is the judge who must determine if there is probable cause to issue the warrant, they must believe that the informant’s information is reliable. This may be established by:

The informant’s identity

The judge may require disclosure of the informant’s name or may require them to give a statement under oath as to the information they provided to the police. 15 However, just because the informant’s identity is disclosed to the judge does not mean it will necessarily be disclosed to the defense.

A judge is allowed to seal any or all of the affidavit to protect the identity of a confidential informant if that testimony helped establish the probable cause that led the judge to issue the warrant. 16

Although the judge will not reveal the informant’s identity simply because you wish to use it to attack the judge’s finding of probable cause, they may ask the prosecutor to disclose it if your motion to traverse and quash the search warrant has merit. 17

attorney working on a document - lawyers can make a motion to quash and traverse a search warrant in California

A lawyer can challenge the validity of a search warrant in multiple ways.

4. How can a defense lawyer challenge the validity of a search warrant?

Although motions to quash and traverse would be more appropriately explained in the final section titled “Motion to Suppress Evidence“, they merit discussion here. They directly relate to informants and the probable cause required to obtain California search warrants.

A motion to “quash and traverse” challenges the affidavit (and underlying probable cause) that the judge relied on upon issuing the California search warrant:

Although these motions may be filed separately or together, the terms are often used interchangeably. We will discuss them as one for the sake of simplicity.

California criminal defense lawyers may assert motions to traverse and quash a search warrant in three types of hearings:

  1. in a Franks hearing (to assert that the author of the affidavit (otherwise known as the “affiant”) provided false information,
  2. in a Luttenberger hearing (to assert that the informant provided false information), or
  3. in a Hobbs hearing (which is based on a sealed affidavit).

Franks hearings

If you request a Franks hearing to quash and traverse a warrant because you believe the supporting affidavit contains false information, you must set forth the reasons why you believe that it is inaccurate. 18 California criminal defense lawyers may do this by demonstrating that:

  1. the affidavit contained a false statement,
  2. the statement was made knowingly or with reckless disregard for the truth, and
  3. that the statement was necessary (that is, “material”) to establish probable cause. 19

It should be noted that if the affiant intentionally leaves out material information, they will be deemed to have provided materially false information “by omission”. 20

The court must hold an “in camera” hearing if the judge believes that you have effectively challenged the truth of the affidavit. 21 An in-camera hearing is a private hearing held in the judge’s chambers.

During this hearing, the judge may question the affiant or informant to determine whether the affidavit is accurate, false, or misleading. 22

If the criminal defense attorney succeeds in proving that

  1. the affidavit contained false material information, and
  2. the remaining information is insufficient to support a finding of probable cause,

the judge must quash the California search warrant.

Once the search warrant is quashed, any evidence that was seized under the warrant will be suppressed. 23

*Suppressed evidence is discussed in the section titled “Motion to Suppress Evidence”.

Luttenberger hearings

When the affidavit supplying the probable cause contains information from an undisclosed informant, it is extremely difficult to establish that the affidavit is false – which is the standard to get a Franks hearing.

If the informant is not a material witness with respect to your guilt or innocence (an eyewitness to the alleged crime, for example), the prosecution is under no duty to disclose their identity. 24

A Luttenberger hearing takes place when you want to attack the truth of the affidavit but do not know the identity of the informant. In this hearing, the California criminal attorney may request information about:

  1. the informant’s reliability,
  2. their motive for providing information (for example, was the informant paid or offered leniency in exchange for their testimony?), and
  3. any statements that the informant made in connection with the case.

Although the burden of proof is less strict than a Franks hearing, the defense still must cast doubt as to the truthfulness of the informant’s testimony. If you accomplish this, the court will conduct an in camera hearing to determine if the statements are material. 25

If the statements are material, the court will redact (or remove) any information that may disclose the informant’s identity before it provides you with the

If, during this hearing, you discover that the informant is a material witness to your guilt or innocence, you would move to disclose their identity at a Hobbs hearing.

Hobbs hearings

At a Hobbes hearing, the defense asks the judge to reveal the identity of the confidential informant upon whose information the California search warrant got issued.

When the entire affidavit has been sealed to protect the informant’s identity, it may be too difficult even to qualify for a Luttenberger hearing. When this is the case, the court must conduct an in-camera hearing upon receipt of your motion to traverse or quash the California search warrant. 27

Unless the prosecutor agrees, the hearing takes place without you or your criminal defense attorney. 28 During this closed hearing, the judge must decide

  1. whether to maintain the confidentiality of the informant, and
  2. whether the affidavit has been properly sealed. 29

If the court believes that the affidavit was properly sealed but does not believe that the information contained in it was false or misleading, it will simply deny your motion. 30

If, however, the court believes that you may succeed in your motion, it will first give the prosecution the opportunity to disclose their informant or have the case dismissed if the judge rules in your favor. 31

In our experience, the prosecution will generally dismiss the case before revealing or “burning” the police informant.

5. How are the police allowed to execute a warrant?

The contents of a California search warrant must be described with reasonable particularity. 32

Simply put, “reasonable particularity” means that the warrant should be so clear that nothing is left to the officer’s discretion when executing it. 33 This applies to both

  1. the place to be searched, and
  2. the person/property to be seized. 34

This means that a search warrant must be executed according to the exact details contained in the warrant 35 – warrants that are clear in their descriptions will be upheld and those that are unduly vague will not.

The following are some examples taken from actual California court cases regarding law enforcement agency searches: 36

Descriptions that were found not to be sufficiently clear —

Items that were described with reasonable particularity —

The more specific the language, the more likely the California search warrant will be upheld.

Time of execution

A California search warrant must be executed within ten (10) days of its issuance. If it has not been executed within that timeframe, it becomes void. 37

If the warrant expires, it may be reissued as long as the judge still believes there is probable cause to support it. 38 It, therefore, follows that if the probable cause that existed at the time of the original issuance is no longer relevant, the judge will not reissue the warrant.

There are also restrictions on what time of day a warrant may be executed. As a general rule, a search warrant may only be executed between 7 a.m. and 10 p.m. If, however, the judge finds good cause, they may authorize service at any time of the day or night. 39

“Good cause” means that there is a factual basis for believing that a nighttime intrusion would be justified based on exigent circumstances. 40 If, for example, you have several outstanding warrants, service will be authorized whenever possible.

When establishing good cause, the judge must consider both

With respect to seized property…

The officer must provide a detailed receipt for any property that they seized during the search. The officer must leave the receipt with

  1. the person from whom they took the property,
  2. the person who possessed the property, or
  3. where they found the property if it was taken without anyone being present. 42

Once taken, the officer must keep the property in police custody until they present it to the court. 43

All that said, the police are not permitted to search and seize anyone or anything until they have announced their presence.

6. What is the knock and announce rule?

Before an officer may execute a California search warrant at your home (or possibly your business 44 ), the officer must

It should be noted that the third requirement may technically be completed after you open the door but in either event must be before the officer enters the home. 46

There is no steadfast rule as to exactly how these knock-notice (also referred to as the “knock and announce rule“) requirements should be executed. So in order to determine whether the executing officers have legally fulfilled their duties under California’s knock-notice law, the court will look for substantial compliance.

Substantial compliance,” in its simplest terms, means that the policies underlying the knock and announce requirements are achieved under the circumstances. 47 These policies include:

  1. protecting a homeowner’s privacy,
  2. protecting innocent people on the premises,
  3. preventing situations that may otherwise encourage a violent confrontation between a homeowner and those who enter their home without notice, and
  4. protecting the police from a startled or fearful homeowner/occupant. 48

The knock-notice rules and the policies behind them are to ensure that if and when the police force entry into your home, it is only because you knowingly refused their entry.

Forced entry

When is it okay for law enforcement officers to enter a home without permission? After their entry has been refused.

If you (as the owner or occupant) refuse to

the police may break in through a door, window, or any other part of the house to execute the California search warrant. 49 The same holds true if no one is home. 50

Assuming you are home, there must be some evidence of a refusal before the police may legally force their way in. This is most typically evidenced by either

Some examples of situations where California courts have held that unlawful forced entries took place include:

There are, of course, certain times when officers are permitted to execute a California search warrant by forcing their entry even without complying with the knock-notice requirements.

Exceptions to California’s knock-notice rule

The following are some of the most common exceptions to the knock and announce requirement:

When exigent circumstances are present, the knock-notice requirements may be waived. This is most typically the case where police suspect that those inside the home

if they first knock and announce their presence.

There is no blanket exception for exigent circumstances, as each case must be independently evaluated. 60 The judge will likely excuse a knock-notice violation

“[I]f the specific facts known to the officer before his entry are sufficient to support his good faith belief that compliance will increase his peril, frustrate the arrest, or permit the destruction of evidence[.]” 61

Absent one of these recognized exceptions, a knock-notice violation may render any subsequent search and seizure unreasonable, and therefore, illegal. 62 When a search and/or seizure is illegal, the prosecution will be prevented from using any of the seized evidence against you at trial. 63

7. What is a motion to suppress evidence?

The most common challenge to a search warrant lies in a California Penal Code 1538.5 PC motion to suppress evidence. This motion may be filed if you wish to

  1. recover seized evidence, or
  2. exclude seized evidence from your trial.

A California criminal defense attorney may file an “unreasonable search and seizure” Penal Code 1538.5 motion based on any of the following facts:

If any part of the search was unlawful, any discovered evidence will typically be excluded under this section. As John Murray, one of Ventura’s top criminal defense attorneys, puts it,

“This ‘exclusionary rule’ is one of the most powerful defenses available.”

If your motion is granted, the prosecution will be prohibited from “using” the seized evidence against you at trial. A victory on this motion will often lead the prosecutor to dismiss (or at the very least significantly reduce) your charge(s).

If, after reasonable efforts, the party serving the warrant is unable to locate the person, the special master shall seal and return to the court, for determination by the court, any item that appears to be privileged as provided by law.
(d)
(1) As used in this section, a “special master” is an attorney who is a member in good standing of the California State Bar and who has been selected from a list of qualified attorneys that is maintained by the State Bar particularly for the purposes of conducting the searches described in this section. These attorneys shall serve without compensation. A special master shall be considered a public employee, and the governmental entity that caused the search warrant to be issued shall be considered the employer of the special master and the applicable public entity, for purposes of Division 3.6 (commencing with Section 810) of Title 1 of the Government Code, relating to claims and actions against public entities and public employees. In selecting the special master, the court shall make every reasonable effort to ensure that the person selected has no relationship with any of the parties involved in the pending matter. Information obtained by the special master shall be confidential and may not be divulged except in direct response to inquiry by the court.
(2) In any case in which the magistrate determines that, after reasonable efforts have been made to obtain a special master, a special master is not available and would not be available within a reasonable period of time, the magistrate may direct the party seeking the order to conduct the search in the manner described in this section in lieu of the special master.
(e) Any search conducted pursuant to this section by a special master may be conducted in a manner that permits the party serving the warrant or that party’s designee to accompany the special master as the special master conducts the search. However, that party or that party’s designee may not participate in the search nor shall they examine any of the items being searched by the special master except upon agreement of the party upon whom the warrant has been served.
(f) As used in this section, “documentary evidence” includes, but is not limited to, writings, documents, blueprints, drawings, photographs, computer printouts, microfilms, x-rays, files, diagrams, ledgers, books, tapes, audio and video recordings, films, and papers of any type or description.
(g) No warrant shall issue for any item or items described in Section 1070 of the Evidence Code.
(h) No warrant shall issue for any item or items that pertain to an investigation into a prohibited violation, as defined in Section 629.51.
(i) Notwithstanding any other law, no claim of attorney work product as described in Chapter 4 (commencing with Section 2018.010) of Title 4 of Part 4 of the Code of Civil Procedure shall be sustained where there is probable cause to believe that the lawyer is engaging or has engaged in criminal activity related to the documentary evidence for which a warrant is requested unless it is established at the hearing with respect to the documentary evidence seized under the warrant that the services of the lawyer were not sought or obtained to enable or aid anyone to commit or plan to commit a crime or a fraud.
(j) Nothing in this section is intended to limit an attorney’s ability to request an in-camera hearing pursuant to the holding of the Supreme Court of California in People v. Superior Court (Laff) (2001) 25 Cal.4th 703.
(k) In addition to any other circumstance permitting a magistrate to issue a warrant for a person or property in another county, when the property or things to be seized consist of any item or constitute evidence that tends to show a violation of Section 530.5, the magistrate may issue a warrant to search a person or property located in another county if the person whose identifying information was taken or used resides in the same county as the issuing court.
(l) This section shall not be construed to create a cause of action against any foreign or California corporation, its officers, employees, agents, or other specified persons for providing location information.
