Warrants

The short version

Warrants are legal documents issued by a judge that allow law enforcement to do certain things, like arrest you or search your property. They are a critical part of your rights under the U.S. Constitution, ensuring police have a good reason before acting. Knowing about different types of warrants, like arrest, bench, and search warrants, helps you understand your legal protections. If a warrant is issued against you, it means a court has found a reason to allow police action.

The law this is built on

Every point below comes from the authority named next to it. Verify the current text before relying on it.

U.S. Const. amend. IV
This amendment protects people from unreasonable searches and seizures. It states that warrants can only be issued if there is 'probable cause,' supported by oath or affirmation, and they must specifically describe the place to be searched and the persons or things to be seized.
Why it matters: This means police generally need a judge's approval (a warrant) before searching your home or arresting you, and they can't do it just because they feel like it.
U.S. Const. amend. V
Among other things, this amendment states that no person 'shall be compelled in any criminal case to be a witness against himself.' It also guarantees 'due process of law' before someone can be deprived of life, liberty, or property.
Why it matters: This protects you from being forced to testify against yourself and ensures fair legal procedures are followed, even when a warrant is involved.
18 U.S.C. § 3041 (Federal law)
This federal law explains that federal judges and certain other officials can issue warrants for arrest or search. These warrants are used when someone has broken a federal law.
Why it matters: This shows that federal agents must also follow warrant rules when investigating federal crimes, just like state police must follow state rules.
State criminal codes (e.g., California Penal Code § 813)
State laws, like those found in state criminal codes, detail the specific procedures for issuing, serving, and returning warrants within that state. They often define what 'probable cause' means in practice for their state courts.
Why it matters: While the U.S. Constitution sets the general rules, your state's laws provide the exact details on how warrants are handled where you live.

Words you need to know

Arrest Warrant: A legal document issued by a judge that gives law enforcement permission to arrest a specific person. It requires probable cause that the person committed a crime.
Search Warrant: A legal document issued by a judge that allows law enforcement to search a specific place for specific items. It must be based on probable cause that evidence of a crime will be found there.
Bench Warrant: A type of arrest warrant issued by a judge directly 'from the bench' because someone failed to appear in court as ordered or violated a court order. It's often for contempt of court or failure to comply with a subpoena.
Probable Cause: A reasonable belief, based on facts and circumstances, that a crime has been or is about to be committed (for an arrest warrant) or that evidence of a crime will be found in a particular location (for a search warrant).
Affidavit: A written statement made under oath. Police officers typically submit an affidavit to a judge explaining why they believe there is probable cause for a warrant.
Exigent Circumstances: Emergency situations that allow law enforcement to act without a warrant, such as when there is an immediate threat to public safety or a risk that evidence will be destroyed. These are exceptions to the warrant rule.

Your rights

✓You have the right to know if a police officer has a warrant for your arrest or to search your property (U.S. Const. amend. IV).
✓You have the right to see a physical copy of a search warrant before police begin their search (U.S. Const. amend. IV).
✓You have the right to remain silent if you are arrested or questioned (U.S. Const. amend. V).
✓You have the right to an attorney if you are arrested or charged with a crime (U.S. Const. amend. VI).

How the process actually works

1
Police gather information
Before any warrant is sought
Law enforcement investigates a crime and collects evidence, witness statements, or other facts that suggest a person committed a crime or that evidence is in a certain place.
2
Police request a warrant
After sufficient probable cause is established
An officer writes an affidavit (a sworn statement) explaining the probable cause for the warrant. This affidavit must detail why an arrest is justified or what they expect to find and where.
3
Judge reviews request
Typically within hours or days of the request, often expedited for emergencies
A judge or magistrate examines the affidavit to determine if there is indeed probable cause. They look for specific facts, not just hunches or suspicions.
4
Warrant issued (or denied)
Immediately after judge's review
If the judge finds probable cause, they issue the warrant, signing it and specifying what it allows (who to arrest, where to search, what to seize). If not, the request is denied.
5
Warrant served
Varies by warrant type and urgency, typically within a few days for search warrants
Law enforcement executes the warrant by making the arrest or conducting the search. For a search, they must present the warrant (or a copy) to the person whose property is being searched.
6
Post-warrant procedures
Immediately after arrest or search
After an arrest, the person is booked and processed. After a search, officers must leave an inventory of items seized. Both typically lead to court proceedings.

Deadlines that can end your case

Search warrant execution
Varies by state (typically 10-15 days from issuance)
If not executed within this window, the warrant usually expires and a new one must be obtained, unless renewed by the court.
Arrest warrant execution
Generally no expiration date for a valid arrest warrant
An arrest warrant remains active indefinitely until the person named in it is arrested or the warrant is recalled by the court. However, some states may have rules for old warrants.
Return of warrant
Varies by state (often within 3-10 days after execution)
After a search warrant is executed, officers must usually return it to the court with a list of what was seized. Missing this could affect the admissibility of evidence.

Costly mistakes

✕Resisting arrest when presented with an arrest warrant, which can lead to additional charges.
✕Interfering with officers executing a search warrant, which can also lead to more charges.
✕Trying to hide or destroy evidence when a search warrant is being executed.
✕Failing to appear in court for a scheduled hearing, which almost always results in a bench warrant.
✕Not asking to see the warrant (or a copy) when police arrive to search your property, although police are not always required to show it before entering.
✕Answering police questions without a lawyer present, even if you are not formally arrested yet (U.S. Const. amend. V).

Your checklist

If police contact you about a crime, politely ask if you are free to leave. If yes, you can leave.
If police say they have a warrant for your arrest, do not resist. Ask what the warrant is for and remain silent until you speak to a lawyer.
If police arrive to search your property, ask to see the search warrant. Note the date and what it says they can search for.
Do not obstruct or interfere with officers executing a warrant, even if you believe it is invalid.
Do not consent to any searches that are not covered by the warrant. Clearly state you do not consent.
Write down everything you remember about the encounter as soon as possible after it happens.
Contact a lawyer immediately if you are arrested or if your property is searched.

Common questions

Can police search my house without a warrant?

Generally, no, unless there's an emergency (exigent circumstances), you give them permission, or the items are in plain view. The U.S. Constitution (Amendment IV) protects against unreasonable searches without a warrant based on probable cause.

What happens if I have an active arrest warrant?

An active arrest warrant means law enforcement can arrest you at any time. It's often best to consult an attorney to discuss options for turning yourself in or having the warrant addressed in court.

What's the difference between an arrest warrant and a bench warrant?

An arrest warrant is typically issued when there is probable cause that you committed a crime. A bench warrant is issued directly by a judge when you fail to follow a court order, like not showing up for a hearing or violating probation.

Do police have to show me the warrant?

For a search warrant, police should show you the warrant or leave a copy. For an arrest warrant, they must inform you that they have one, but they don't always have to physically show it to you at the moment of arrest, especially for safety reasons. However, you are entitled to see it eventually.

Can a warrant be issued over the phone?

Yes, in some situations and in some states, judges can issue warrants over the phone or electronically, especially for urgent matters. This is often called a 'telephonic' or 'e-warrant' and is still based on an officer's sworn statement of probable cause.

How this changes by state

While the Fourth, Fifth, and Sixth Amendments to the U.S. Constitution set the basic rights for warrants across the country, each state has its own specific criminal codes and rules of criminal procedure. These state laws determine the exact requirements for probable cause, the validity period of warrants, how they are served, and what happens after they are executed. For example, the time limit for executing a search warrant can vary from 10 days in one state to 15 days in another. You can find your state's specific rules by looking at its Code of Criminal Procedure or consulting with a local attorney.

When you need a lawyer

You should contact a lawyer immediately if you believe there is a warrant for your arrest, if police attempt to search your property with or without a warrant, or if you are questioned by law enforcement about a crime. A lawyer can advise you on your rights, review the warrant's validity, and represent you in court to protect your interests.
