Jurisdiction and Case Types in Family Court Long Island NY

Family Court on Long Island deals with legal issues that affect children, parents, and domestic partners. As of September 2026, the 10th Judicial District operates busy Family Court parts across Nassau and Suffolk counties. Knowing which court handles your legal problem is the first step to getting real relief.

The court handles many types of cases:

• Child custody and parenting time schedules
• Child support and spousal support petitions
• Paternity establishment (proving who the legal father is)
• Family offense petitions to get an order of protection
• Child abuse and neglect investigations involving Child Protective Services (CPS)
• Persons in Need of Supervision (PINS) for struggling teens
• Guardianship and voluntary foster care placement
• Private and agency adoptions

Understanding How Custody is Decided in Suffolk County Family Court helps parents prepare for the legal standards judges use when setting schedules.

Case Types Handled: From Child Support to Custody

Different court officials handle different matters. Child support cases go before Support Magistrates. These magistrates have the authority to review income, determine basic support amounts under New York guidelines, and order health insurance contributions.

Custody and parenting time disputes go directly before Family Court Judges or Court Attorney Referees. If parties cannot reach an agreement, the judge schedules a trial. You can learn more about What Happens at a Fact Finding Hearing in Suffolk County Family Court to understand how testimony and evidence work during trials.

Child welfare cases involve CPS claims of abuse or neglect. In these urgent cases, the judge decides whether a child is safe at home or needs temporary placement with a relative. For safety concerns between partners or family members, the court issues temporary orders of protection. These orders can direct someone to stay away from a home, school, or job.

Family Court vs. Supreme Court Jurisdiction on Long Island

A common point of confusion is the difference between Family Court and Supreme Court.

• Supreme Court: In New York, the Supreme Court is the only court that can grant a legal divorce and divide marital property (equitable distribution).
• Family Court: Family Court cannot grant a divorce. It handles custody, visitation, and child support when parents are unmarried, or when married parents need support or custody orders before or after a divorce.

If you have an active divorce in Nassau or Suffolk Supreme Court, custody and support are usually handled there as part of matrimonial actions. You can consult the Nassau Supreme Court Phone Directory for matrimonial parts.

When there are both criminal charges and family offense petitions between the same parties, the case may move to an Integrated Domestic Violence (IDV) Part. The IDV Part allows one single judge to handle the criminal case, custody, and protective orders together.

Locations, Phone Directories, and Contact Information

Long Island Family Courts are open Monday through Friday from 9:00 AM to 5:00 PM, excluding state holidays. You should arrive early to clear security.

How to Start a Case and File Petitions on Long Island

To start a case in Family Court, you must file a legal document called a petition. The person starting the case is the petitioner, and the person responding is the respondent.

You must file a separate petition for each legal request. For example, if you want custody and child support, you must file one custody petition and one child support petition.

You can obtain standard forms directly at the clerk's office or use official Family Court Suffolk County Forms. The New York State Unified Court System also offers online DIY (Do-It-Yourself) form programs for unrepresented individuals filing uncontested paternity, support, or custody modifications. Unlike civil Supreme Court, there are no filing fees to submit a petition in Family Court.

Role of the Probation Department and Child Support Enforcement Bureau

In Suffolk County, the Probation Department assists self-represented parties with drafting and filing petitions. You can schedule an intake appointment by calling 631-853-4246 or 631-853-4256.

For child support issues, you can also work with the Child Support Enforcement Bureau (CSEB). The Suffolk County CSEB office is located at 3455 Veterans Memorial Highway, Ronkonkoma, NY 11779, and can be reached by phone at 1-888-208-4485. CSEB can locate non-custodial parents, establish paternity, file support petitions, and collect payments through wage garnishment.

Serving Papers and Preparing Initial Filings for Family Court Long Island NY

Once you file your petition, the court issues a summons and a copy of your petition. These documents must be formally delivered ("served") to the respondent.

If you have been served, read Served with Family Court Papers in Suffolk County Heres What to Do Next to avoid missing deadlines.

Rules for service include:

• You cannot hand the papers to the other party yourself.
• Any person who is 18 years of age or older and not a party to the case can complete service.
• You can hire a professional process server or ask the local Sheriff's Department.
• The person who serves the papers must sign a sworn, notarized Affidavit of Service.
• You must file this original Affidavit of Service with the court before or on your first appearance date.

If you are facing an emergency involving domestic abuse or imminent danger to a child, you can file an emergency ex parte petition. An ex parte petition allows a judge to hear your request immediately without notifying the other party first, granting temporary protection until formal service occurs.

What to Expect on Your Appearance Date and Courtroom Procedures

Your first appearance sets the roadmap for the entire case. To learn more about the initial schedule, see What to Expect at Your First Family Court Hearing in Suffolk County.

Courts manage heavy dockets, which explains Why Family Court Cases in New York Take So Long to Resolve. Cases often require multiple court dates over several months.

Before your appearance, assemble your documentation checklist:

• A clean copy of your filed petition and summons
• The original notarized Affidavit of Service
• Government-issued photo identification
• Certified birth certificates of the children
• Financial disclosure affidavits, W-2 forms, 1099s, and your last three pay stubs (for support cases)
• Police incident reports, photos, medical bills, or text message logs (for family offenses)

When entering the courtroom, dress neatly and professionally. Turn off your cell phone. Speak only when addressed by the judge, magistrate, or court referee, and answer all questions clearly and honestly.

Arrival, Security Checkpoints, and Checking In at the Court Part

When you arrive at the courthouse in Westbury, Central Islip, or Riverhead, you must pass through security magnetometers and have your bags scanned. Weapons, sharp objects, and recording devices are prohibited.

After passing security:

1. Find your assigned Part (courtroom) on the electronic calendar boards in the lobby using your name or docket number.
2. Walk directly to that courtroom part.
3. Check in with the court officer or clerk standing outside or sitting inside the courtroom door.
4. Take a seat in the waiting area until the court officer calls your case calendar number.
5. Step up past the swinging wooden gate (the bar) to the counsel tables when your case is called.

Resolving Matters in Family Court Long Island NY: Orders, Objections, and Appeals

At the end of your hearing, the judge or magistrate will issue a ruling:

• Temporary Order: Stays in effect until the next scheduled appearance. It sets interim custody, parenting time, or support while the case proceeds.
• Final Order of Disposition: Resolves the petition permanently. It remains in effect until modified by a future court order or until the child reaches legal adulthood.

If you disagree with a final decision made by a Support Magistrate, you have 30 days from the date the order is received (or 35 days if mailed) to file written legal Objections with the Family Court clerk. A Family Court Judge will review the objections and the magistrate's record.

If you disagree with a final order issued by a Family Court Judge, your remedy is to file an appeal with the Appellate Division of the New York State Supreme Court, Second Judicial Department, located in Brooklyn. Appeals must be filed within 30 days of service of the order. If you cannot afford transcript costs for an appeal, you can submit a "Poor Person Motion" to request a fee waiver.

Why Quality Human Representation Matters

Navigating court rules requires careful attention. Some people try using AI tools to draft family law petitions or custody agreements. We strongly warn readers against using AI to draft family law agreements. Generic robotic documents lack legal nuance, miss mandatory statutory language, and can ruin a family's life for years with unenforceable terms.

Only an experienced human attorney with local Suffolk County legal insight and empathy can protect your parental rights and secure your family's future.

Transparent Flat-Fee Legal Guidance

At Zacarese & Zalewski P.C., we believe families deserve total financial certainty during difficult transitions. That is why Steven Zalewski operates on a transparent flat-fee model:

• Pre-Trial Fee: Covers all legal work leading up to trial, including drafting petitions, handling discovery, filing motions, conducting negotiations, and attending all court appearances—regardless of how many times you must appear in court.
• Trial Fee: A set, predictable fee due 30 days before trial begins if your case does not settle out of court.
• Payment Plans Available: We offer flexible payment plans to ensure quality representation remains accessible.

Many other firms charge steep hourly rates that skyrocket when cases become complex, or they abandon clients who run out of money mid-case. In contrast, Steven Zalewski's flat-fee approach guarantees dedicated, continuous advocacy from start to finish.

Frequently Asked Questions About Long Island Family Court

How can I check my court date or case status online?

You can verify your court appearance using the New York State Unified Court System's free online portal, eCourts WebFamily. Search by your File Number or Docket Number to see scheduled future appearance dates, assigned parts, and presiding judges.

That WebFamily only tracks cases with scheduled future appearances. You can also review the Suffolk Family Court Frequently Asked Questions | New York Courts or call the General Clerk's Office at 631-740-3800 (Central Islip) or 516-493-4000 (Nassau) with your docket number to confirm hearing times.

Can I get a free court-appointed lawyer for my case?

Under Section 262 of the New York Family Court Act, low-income litigants have a statutory right to free court-appointed counsel (known as "18-b" attorneys or Legal Aid Society attorneys) in specific proceedings:

• Child custody and visitation matters where a parent faces loss of custody
• Family offense cases (orders of protection)
• CPS abuse or neglect cases
• Child support violation matters where incarceration is requested

To request a court-appointed attorney, tell the judge or magistrate at your first court appearance. You will be directed to complete a detailed financial screening affidavit disclosing your income, assets, and expenses to determine if you qualify.

What happens if I miss a court date or fail to follow an order?

Missing a court date without permission can lead to serious consequences. The judge can issue a default judgment against you, granting the other party's full petition in your absence. If you are a respondent in a violation or contempt proceeding, the judge can issue an arrest warrant (bench warrant).

If you cannot attend due to a verified emergency, submit a written adjournment request to the clerk and opposing counsel before the court date. If an emergency causes you to miss court, your attorney must immediately file an Order to Show Cause to vacate the default judgment, showing a reasonable excuse and a meritorious defense.

Violating a final court order can result in a violation petition, financial sanctions, loss of custody, or jail time for civil or criminal contempt.
