Understanding the Difference Between Arrest and Search Warrants
In California criminal law, arrest warrants and search warrants serve different legal purposes. Both require judicial authorization and must be supported by probable cause, but they authorize very different law enforcement actions.
An arrest warrant allows police to take a person into custody. A search warrant allows police to search a person, place, or property for evidence of a crime.
Understanding the distinction is critical if you or a loved one is under investigation, has been arrested, or has had property searched.
Our Los Angeles criminal defense attorneys regularly challenge unlawful warrants, improper searches, and constitutional violations under the Fourth Amendment and California law.

What Is an Arrest Warrant in California?
An arrest warrant is a court order signed by a judge authorizing law enforcement to arrest a specific person based on probable cause.
Probable cause means there is sufficient evidence to reasonably believe the person committed a crime.
How Arrest Warrants Are Issued
To obtain an arrest warrant:
-
A police officer submits a sworn declaration (affidavit)
-
The declaration explains the alleged crime and supporting evidence
-
A judge reviews the information
-
If probable cause exists, the judge signs the warrant
The warrant includes:
-
The defendant's name
-
The issuing county
-
The judge's signature
When Is an Arrest Warrant Required?
An arrest warrant is typically required when:
-
The crime was not committed in the officer's presence
-
Charges are filed after an investigation
-
A prosecutor files a case “with a warrant”
-
A grand jury issues an indictment
If police personally observe a crime being committed, they may arrest without a warrant.
Can Police Enter Your Home with an Arrest Warrant?
Yes, under certain conditions.
If officers have a valid arrest warrant and reasonably believe you are inside your residence, they may enter your home to execute the warrant.
However:
-
If you are a guest in someone else's home, police generally need a search warrant to enter that home.
-
Officers may use reasonable force if entry is refused.
These distinctions frequently become central issues in suppression motions.
What Is a Grand Jury Indictment?
A grand jury is a panel of citizens that determines whether probable cause exists to formally charge someone with a crime.
Grand jury proceedings are secret. If the grand jury issues an indictment, the court will issue an arrest warrant.
Grand jury indictments are more common in serious felony cases.
What Is a Search Warrant in California?
A search warrant authorizes law enforcement to search:
-
A specific location
-
A specific person
-
A specific vehicle
-
Specific items
Under the Fourth Amendment to the United States Constitution, a search warrant must:
-
Be supported by probable cause
-
Particularly describe the place to be searched
-
Particularly describe the items to be seized
If these requirements are not met, the search may be unconstitutional.
How Search Warrants Are Issued
To obtain a search warrant:
-
An officer submits a sworn affidavit
-
The affidavit explains why evidence is likely to be found
-
A judge reviews the statement of probable cause
-
If sufficient evidence exists, the judge signs the warrant
Search warrants generally expire after a short time and must be executed within a specific window.
What Is a Probable Cause Statement?
The probable cause statement is the written affidavit supporting the warrant.
It must establish:
-
A crime occurred
-
Evidence exists
-
The evidence is likely located in the place to be searched
If the affidavit is misleading, incomplete, or lacks sufficient evidence, the warrant may later be invalidated.
The Plain View Doctrine
If officers are lawfully inside a location executing a valid search warrant, they may seize illegal items in plain view.
For example:
-
Officers executing a warrant for stolen property see narcotics on a table.
-
Even if drugs were not listed in the warrant, they may be seized if immediately recognizable as contraband.
This doctrine is often contested in suppression hearings.
Time Restrictions and Knock-and-Announce Rules
Search warrants typically:
-
Must be executed during specified hours
-
Require officers to knock and announce their presence
However, judges may authorize:
-
Nighttime searches
-
No-knock entries
These exceptions require additional justification and are frequently litigated in court.
Motion to Suppress Evidence – Penal Code 1538.5
One of the most powerful defense tools in California is a motion to suppress under Penal Code 1538.5.
A motion to suppress challenges:
-
Lack of probable cause
-
Defective warrant affidavits
-
Overbroad search terms
-
Improper execution
-
Constitutional violations
If a judge determines the warrant was invalid, evidence obtained during the search may be excluded from the case.
Without key evidence, prosecutors may be forced to reduce or dismiss charges.
What Happens If a Warrant Was Issued Improperly?
If a warrant lacked probable cause or was based on false or misleading information, a court may:
-
Suppress evidence
-
Dismiss charges
-
Strike enhancements
-
Reduce felony charges
There are limited “good faith” exceptions, but they do not apply in every case.
Each situation requires careful legal analysis.

Warrant challenges are highly technical and time-sensitive. Strategic intervention may allow your attorney to:
-
File a motion to quash the warrant
-
File a motion to traverse the warrant affidavit
-
Challenge probable cause
-
Suppress unlawfully seized evidence
-
Negotiate reduced charges before trial
Early action often determines the outcome.
