Section 303 of a state Mental Health Act authorizes a short-term emergency hold that lets a designated facility detain a person for up to 72 hours for psychiatric evaluation and crisis stabilization. The number traces to the statute itself, not a diagnosis, and it overrides the usual requirement of patient consent when clinicians determine someone poses an immediate danger or cannot meet basic needs.
The phrase appears in the middle of a crisis: a family member in the ER, a loved one in the back of a sheriff’s car, or a patient who just had a security guard block the exit.
This guide covers how a 303 hold actually works in practice, from the legal criteria that justify it to the step-by-step process a family member or concerned clinician navigates in those first tense hours.
The Legal Meaning of a 303 Hold
Section 303 sits inside a state’s Mental Health Act as a narrow, time-limited legal authority for involuntary detention. The statute sets the maximum length (72 hours in most jurisdictions), the categories of people who may invoke it, and the conditions under which a facility may hold a person against their will.
The clinical act of placing someone “on a 303” is the hospital’s execution of that statutory authority, a paper trail that starts with a written application and ends with either a release, a voluntary admission, or a petition for longer-term commitment. “303” is not a psychiatric diagnosis; the legal mechanism simply allows a clinician to evaluate one.
The statute overrides ordinary consent rules for treatment, but only for the duration of the hold and only for emergency stabilization, not for long-term psychiatric care. Once the 72 hours end, ongoing treatment requires either your agreement or a separate court order for extended commitment.
Why the Number, Not the Name
Mental health codes often group related procedures by section number, which is why crisis-unit clinicians say “5150” in California, “302” in Pennsylvania, and “303” in states that adopted that section for emergency detention. The shorthand travels between hospitals, courts, and law enforcement because the section number identifies the specific authority being used and the rules attached to it.
When a clinician says a patient is “on a 303,” you are hearing shorthand for the legal vehicle, not a clinical finding. A patient who stabilizes during the hold is typically discharged with no formal diagnosis; the criteria are about safety, not labels.
Those safety criteria are not abstract, they translate into specific legal grounds that the statute requires a petitioner to articulate.
Grounds That Legally Justify a 303 Commitment
Most state statutes share three core criteria for an involuntary hold, and the 72-hour clock cannot legally start unless at least one of them is documented. Documented behavior, not general worry, is what the statute requires.
- Danger to self: Credible suicidal statements, a recent attempt, active self-harm behavior, or a plan that an evaluating clinician considers feasible. The threshold is specific behavior or a clear statement, not a vague worry about future risk.
- Danger to others: Threats, recent violence, possession of a weapon in the context of a mental health crisis, or a documented inability to control impulses during the current episode.
- Grave disability: Inability to provide for basic needs such as food, shelter, clothing, or safety because of a mental health condition, even when the person does not appear suicidal or aggressive.
These criteria are intentionally narrow. A family argument, a bad day, or a history of treatment alone does not authorize a 303. The evaluating professional must connect the current behavior to one of the three categories and write that justification into the application before detention begins.
What “Credible” Means in Practice
Clinicians look for specifics: a stated method, a time frame, access to means, or observed behavior during the assessment. A patient who says “I wish I weren’t here” generally does not meet the bar; a vague wish to be elsewhere is not a feasible plan.
A patient who describes a plan, hands over a bottle of pills, or is found wandering traffic while disoriented typically does. Documentation of these details in the application is what later protects the patient from arbitrary confinement, and it is what a judge will examine if a hearing is requested.
Who Can Initiate a 303 and How the Process Begins
The list of people authorized to start a 303 is set by statute, and it varies by state, but three groups appear almost everywhere. Each role carries a different evidentiary standard before the 72-hour clock can begin.
- Licensed physicians and psychologists who have personally examined the person and can attest to one of the three criteria.
- Designated mental health professionals, sometimes called DMHPs, who carry county-level authority to screen and authorize holds in the field.
- Peace officers, sheriffs, and certain court officers who can detain a person for transport to a designated facility when probable cause is observed.
In some states, family members can also file a petition directly, but the petition still must be reviewed by a clinician or DMHP before detention becomes legal. The petition is a request, not the hold itself.
How a Family Petition Works
Most family-member petitions run just one to two pages and lay out, with dates and times where possible, the specific behaviors that meet the legal criteria for an emergency hold. Two adult petitioners are often required, and the petition must name a designated facility willing to accept the person.
Once the petition is filed, the receiving facility has its own intake physician confirm the criteria before the hold officially starts. The paperwork is the legal foundation, and it is what a later attorney will examine to check whether the process was done correctly.
Once the paperwork is filed, the clock begins immediately and shapes every decision the facility is about to make.
The First 72 Hours, Hour by Hour
Within a designated facility, the 72-hour clock breaks into distinct phases, each with its own rights, deadlines, and clinical decisions that unfold in a predictable order. Knowing the timeline lets you act before each deadline closes.
Hours 0 to 8: Detention and Rights Notification
Once the hold is authorized, the facility must promptly notify the patient of their legal status and the specific rights that travel with the hold. These typically include the right to legal counsel, the right to a hearing before a judge, and the right to refuse certain medications in non-emergency situations.
Many states also require notification of a listed family member or conservator. Ask the intake nurse for the written notification and keep a copy; it is the document that proves the facility followed the statute.
Hours 8 to 48: Evaluation and Stabilization
The evaluating psychiatrist conducts a fuller assessment, reviews records, speaks with family when possible, and decides whether medications, restraints, or constant observation are clinically necessary. Treatment decisions during this window can be made without the patient’s consent when an emergency exists, but routine medications still require either consent or a court order.
This is the phase where the patient’s history, prior diagnoses, and current behavior get documented in detail, so a clear picture of the case is ready for any later hearing. You can ask the treatment team to copy you on the discharge summary once it is finalized.
Hours 48 to 72: Release, Voluntary Status, or Petition for Extension
By the end of the third day, three things can happen. The patient can be released if the clinician determines the criteria are no longer met. The patient can convert to voluntary status and remain as a regular admission. Or the facility can file a petition for an extended commitment, which triggers a court hearing and a higher standard of proof.
The 72-hour window is a hard legal ceiling, not a guideline, and discharge paperwork must be completed before the clock runs out or the facility must release the patient. If the clock expires without action, the hold ends by operation of law.
Rights That Travel With the Patient
Being on a 303 does not strip a person of every right. Several protections are built into the statute precisely because the state is overriding consent. These rights exist in every state that has adopted a Section 303 framework, though the wording varies.
- Right to legal counsel: You can request a public defender or hire private counsel familiar with mental health court. Make the request in writing and ask for a copy of the acknowledgment.
- Right to a hearing before a judge: A patient can demand a hearing to challenge the hold, and the facility must release the patient if the court does not find grounds for continued detention.
- Right to refuse certain medications: Emergency medication is allowed during a 303, but ongoing psychiatric medication generally requires either consent or a separate court authorization.
- Right to communicate: Reasonable phone access, the ability to contact family, and access to a telephone for legal calls are required in most jurisdictions.
Use these rights early. Waiting until hour 70 to demand a hearing often leaves no time for the court to schedule one before the hold expires.
Collateral Effects to Plan Around
A 303 will appear in medical records, and depending on state law, may be reportable to a database that affects firearm eligibility. Insurance carriers typically cover emergency psychiatric holds, but you should ask the facility’s billing office for the specific billing codes so you can verify coverage.
Employment disclosures are governed by your own state’s record-sealing rules, and many states now allow a 303 record to be sealed after a waiting period if no further commitment occurs. Ask an attorney about the local sealing statute before the record creates problems later.
Where a 303 Fits Among Other Holds and Commitments
A 303 is one piece of a larger legal toolkit, and knowing how the pieces connect helps you anticipate what comes next. The table below compares the four most common mechanisms so you can see where the 303 sits in the chain.
| Mechanism | Maximum Length | Who Authorizes | Purpose |
|---|---|---|---|
| 5150-style pre-screening hold | Often 24 hours or less | Peace officer or DMHP in the field | Transport and initial screening before facility acceptance |
| 303 (Section 303) hold | 72 hours | Physician or designated mental health professional at the facility | Emergency psychiatric evaluation and crisis stabilization |
| 5250-style extended hold | Up to 14 days additional | Court hearing with written evidence | Continued involuntary treatment when criteria persist |
| Conservatorship / LPS | Indefinite, periodic review | Probate or mental health court | Long-term decision-making authority for a person with serious chronic impairment |
The 303 is almost always the first step in a chain, not the last. A patient who stabilizes within 72 hours is usually released or converts to voluntary status. A patient who does not may be moved into a longer hold, which is exactly why early legal involvement matters.
State-by-State Variation
Some counties operate under the Lanterman-Petris-Short Act model, where designated facilities share responsibility and the county often funds a portion of the cost. Other jurisdictions use private contract facilities with different billing rules.
The Section 303 authority is similar across states, but the funding source, the designated facility list, and the paperwork can differ by county. Calling the county mental health office before a crisis gives you the local facility name, the correct petition form, and the name of the public defender who handles mental health cases.
Knowing how a 303 compares to other commitments is useful in theory, but families usually need concrete next steps when a crisis is unfolding.
Practical Steps for Patients and Families
Most of the avoidable harm in a 303 comes from missed paperwork, missed hearings, or missing information. A short checklist keeps you on track.
- Document everything at the first phone call. Write down the names of every clinician, the facility address, the case number, and the time the hold was authorized. These details are easy to lose in the first hours of a crisis.
- Request legal counsel in writing. Ask for a public defender familiar with mental health court, or hire private counsel before the 48-hour mark so a hearing can be scheduled in time.
- Prepare evidence for a potential hearing. Gather recent records, a list of medications and prior diagnoses, character references, and a written timeline of the events that led to the hold. Judges weigh current behavior against documentation, not impressions.
- Confirm release or extension in writing. If the hold is not extended, ask for written discharge instructions including follow-up appointments, medication changes, and crisis-line numbers. Verbal summaries get lost.
- Plan aftercare before discharge. Outpatient commitment options, therapy appointments, and a crisis plan with one trusted contact all reduce the chance of a second hold within the same month.
Request the discharge paperwork in writing, including the formal release time, the final diagnosis if one was made, and the documented reason the hold ended. The paper trail matters more than the conversation.
Supporting Reintegration After Release
The first 30 days after a 303 carry the highest risk of a second crisis. A patient leaving the hospital benefits from same-week outpatient follow-up, a written safety plan, and at least one person who knows what the warning signs look like.
Family members can help by attending the first post-discharge appointment (with the patient’s consent) and by keeping medication schedules consistent. Avoiding shame-based conversations about the hold itself is also protective; the legal process is stressful enough without becoming a family argument.
Frequently Asked Questions
How long does a 303 hold last?
A 303 hold lasts up to 72 hours, not longer, under most state statutes. The clock starts when the hold is formally authorized at the facility, and you must be released, converted to voluntary status, or transferred into a court-ordered extended hold before the 72 hours end.
Can a patient refuse medication while on a 303?
Emergency medication can be administered without your consent during an acute safety crisis, but routine psychiatric medication generally requires your consent or a separate court order. If you object to ongoing medication, request a hearing so a judge can review the clinical justification.
Does a 303 appear on a permanent record?
The hold is documented in your medical record, and in many states the commitment is also reported to a database that affects firearm eligibility. Many jurisdictions now allow the record to be sealed after a waiting period if no further commitment occurs, and an attorney can explain the local sealing rules.
Can a family member be the one to start a 303?
In many states, a family member can file a petition, but the petition alone is not the hold. A clinician or designated mental health professional must independently confirm the legal criteria before detention becomes authorized, and the facility must accept the person for evaluation.
What happens if the hospital wants to keep the person past 72 hours?
The facility must file a petition for an extended hold and obtain a court order before the 72-hour window ends. A hearing is then scheduled, you are entitled to legal counsel, and the judge decides whether the criteria for ongoing involuntary treatment are still met.
