Notarizing a Child Custody Agreement: What Parents Need to Know

Disclaimer: This blog post is for informational purposes only and does not constitute legal advice, and I am a notary public, not an attorney. Custody, visitation, and child support rules in New York can change, and your specific circumstances may call for a family law attorney, a mediator, or a Family Court judge. Always confirm the requirements of your court, your attorney, or the agency requesting the document before relying on any particular notarization.

Of all the documents that cross my desk, the child custody agreement is perhaps the most emotionally charged. Nothing slows a signer down quite like the moment I ask a parent to confirm, on camera, that they understand what they are committing to about where their child will live. Custody agreements are not just legal forms. They are schedules of love, of school pickups, of holiday letters, of who holds the child on Christmas morning and who gets to make the doctor’s appointment in January.

As your New York State Remote Online Notary, I have seen parents hand me custody papers at every stage of their journey. Some are separating amicably and simply want a clean, enforceable agreement before they ever set foot in a courtroom. Some have already had a Family Court judge issue an order and now need it acknowledged or certified. Some are confused about whether the notary is even the right person in the room at all. That last question is more common than you would think, and it is the single most important one in this article.

Here is the honest answer, right up front, before we go any further: a notary public is not a family lawyer, and a notary public is not a Family Court judge. What I do when I notarize your custody agreement is narrow but powerful. I verify your identity, I witness or acknowledge your signature, and I attach a notarial certificate that says, in effect, “this person signed this document and claimed it was their own, free and voluntary act, on this date, before me.” That is all a notary can claim. It does not decide custody. It does not interpret the parenting schedule. It does not order child support. What it does is make your signature a sworn, authenticated event that a court, a school, an airline, or the other parent can rely upon without having to chase you down to prove you actually signed it.

This guide will walk you through what a custody agreement actually is in New York, when notarization helps you and when it does not, what “notarize” really means in the custody context, and exactly how our Remote Online Notarization (RON) session will go from start to finish. By the end, you will know whether you need me at all, and if you do, you will walk in prepared.

A Note on My Role

I am going to be a little more candid than a typical legal website. My value to you is making sure that when you sign, the signature is legally sound, authenticated, and hard to dispute later. If you are in the middle of a heated dispute and no judge has ruled yet, you probably need a family lawyer and possibly a stipulation entered by the court. If you have a signed agreement and want it locked down so neither parent can later claim “I never signed that,” then you have come to the right person. We will cover both scenarios.

Part 1: What Is a “Child Custody Agreement”?

Before we talk about notarizing one, we need to be clear about what the document actually is, because “custody agreement” is a colloquial term that covers several distinct things in New York.

Custody vs. Visitation: The Two Concepts New York Uses

New York law, found in the Domestic Relations Law (DRL) Section 240 and in the Family Court Act, distinguishes between two ideas that laypeople often blur together:

Legal custody (sometimes called decision-making authority): The right to make major decisions for the child, including education, medical care, religion, and extracurricular activities.
Physical custody (sometimes called residence or “parenting time”): Where the child actually lives on a given day or week, and the day-to-day care the child receives.

You can have sole physical custody (the child lives primarily with one parent) and joint legal custody (both parents share major decisions), or any other combination. In New York there is no statutory presumption of a 50/50 split, which is a point that surprises many parents. The court or the parents decide the actual time-sharing arrangement based on the child’s best interests.

The “Best Interests” Standard

When a court decides custody, New York applies a best-interests-of-the-child standard. The Domestic Relations Law does not print a neat list of factors, so the courts have developed a set of considerations over decades of case law (famously catalogued in the decision Eschbach v. Eschbach) that look at, among other things, which parent was historically the primary caregiver, each parent’s fitness, the child’s wishes if the child is mature enough, the stability of each home, and the willingness of each parent to encourage the relationship between the child and the other parent.

Here is the point that matters for you as a parent preparing an agreement: if you and the other parent can agree, the court will generally honor your agreement, provided it genuinely serves the child. That is why so many families prefer a written, signed, notarized settlement over a contested hearing. You get to design the schedule, the holidays, and the decision-making rules yourselves, rather than having a stranger decide them.

The Common Documents You Might Actually Be Holding

When people say “my custody agreement,” they usually mean one of these:

A Stipulation and Order / Settlement Agreement: A signed, written agreement between the two parents that a court can adopt as a court order. This is the most enforceable form, because once it becomes a court order, it can be enforced like any other judgment.
A Parenting Plan: A more detailed, practical document that lays out the actual schedule (weekend rotations, holidays, vacations, decision-making authority, communication rules, what happens in an emergency). Parents often have this even when a short court order is the enforceable document.
A Court Order Already Entered by a Judge: If a Family Court judge has already ruled, the “agreement” is the order on the court’s seal. You may need a certified copy, an acknowledgment, or a certification of copy rather than a fresh notarization.
A Voluntary, Non-Court Parenting Agreement: Two parents who are not yet in court and simply want a written, signed document laying out how they will share the child. This is where notarization shines, because it gives the document the weight of a sworn, authenticated signature even though it has not yet been entered by a judge.

The rest of this article assumes you are in situation #1 or #4, which is where a notary most often comes in.

Part 2: Does a Child Custody Agreement Even Need Notarization?

This is the question I am asked most, and the honest answer is: it depends, and I would rather be honest with you than sell you a notarization you do not need.

When a Custody Agreement Does NOT Strictly Require a Notary

In New York, a basic custody or parenting agreement between two parents who are cooperating does not, by itself, have to be notarized to be a valid contract between them. If both parents sign it, it is a written agreement. If one parent later changes their mind, the other parent can point to the signature. Notarization is not a legal requirement for the two of you to be bound by what you agreed.

Even a custody order entered by a Family Court judge does not always require a notarial acknowledgment, because the judge’s signature and the court’s seal carry the authority.

When a Notary Becomes Very Useful

That said, I frequently recommend notarization for custody documents for the following reasons:

The document will be relied upon outside your home. A school, a camp, a doctor, an airline, or a grandparent in another state may need to see an “official” document confirming who is authorized to pick up the child or make a medical decision. A notarized agreement is far more likely to be accepted than a bare signature, because the notary has independently verified your identity.
You want to head off a later “I never signed that” dispute. When a custody arrangement sours (and in my experience, many do sour), a non-notarized document can be attacked by the argument that the signature is not genuine. A notarial acknowledgment makes that argument much harder to make, because you are affirming under oath that you signed and that it was your own act.
Your attorney, mediator, or the court is asking for it. Many family lawyers and mediators simply require notarization on the final settlement so that the document is court-ready in its execution. If your attorney says “have it notarized,” do it.
You are submitting the agreement as a court exhibit. When the agreement is presented to a Family Court judge as part of a stipulation, a notarized signature helps prove authenticity without having to bring both parents into the courtroom just to confirm they signed.
The document is a certified true copy of an original. If you have the original signed agreement and need to send copies, a notary can certify each copy as a true and correct copy of the original, which is a standard notarial act.

The Critical Distinction: Acknowledgment vs. Jurat

This is where most parents get tripped up, and it is worth spelling out because it changes what I will actually do in our session.

Acknowledgment is the standard act for custody and other signed agreements. In an acknowledgment, you appear before me and declare that you signed the document freely and voluntarily. The notary then attaches a certificate stating that you “acknowledged” the signature as yours. This is the act you want for a custody agreement, and it is the act I perform in virtually every custody document that reaches my desk.
Jurat (often called a sworn affidavit) is a different act. In a jurat, you swear that the contents of a document are true and correct. You typically use a jurat for affidavits and declarations, not for the underlying custody agreement itself. Occasionally a custody packet includes a separate affidavit (for example, an affidavit of service proving you mailed the other parent the papers) that requires a jurat. If your document is an affidavit rather than an agreement, I will perform a jurat instead.

When you call your notary, tell them which document it is. “Custody agreement” means acknowledgment. “Affidavit” means jurat. It is a small distinction, but it is the difference between two different legal acts.

Fees You Should Expect

Under New York law, the standard notarial fee is capped at $2 per acknowledgment or oath for an in-person notarization, under Executive Law Section 136. For Remote Online Notarization, the cap is $25 per electronic notarial act, under Executive Law Section 135-c. If you use me remotely, expect to be charged the $25 RON fee, which covers the technology, the recording, and the convenience of doing this from your home or office rather than driving to a notary’s office. There is no separate travel fee for RON in New York, because we are both in the same room through a video call.

Part 3: How to Prepare Your Custody Agreement for Notarization

Before our session, I want you to have everything ready so we can finish in one sitting.

Have the Document Fully Written and Unsigned (or Partially Signed) A custody agreement should be completely filled out before the notary touches it. Every blank should be filled. Every schedule, every holiday assignment, every decision-making allocation, should be typed in. New York rules are strict that a notary should not sign or write anything on the document except the notarial certificate. If there are blanks, fill them in before you sign. If a blank needs to be filled by a party, that party fills it in. Never leave a blank for the notary to fill.
Sign the Document, Not Me The most common mistake I see is parents signing in front of me but not understanding that I am witnessing their signature, not their document. In an acknowledgment, you (the parent) sign the document first, in my presence (on camera, for RON). I then attach my certificate. Do not let me sign for you. Do not sign before I can verify you. Sign on camera, on my watch, and I will take it from there.
Have a Valid Photo ID Ready For RON, New York requires a process called “Credible Identification.” You will need:

A valid, unexpired government-issued photo ID, such as a New York driver’s license or a U.S. passport. Your ID must be legible to the camera. I will scan the data on the ID, including the machine-readable zone, to confirm it is authentic and current. I will also ask you a few Knowledge-Based Verification (KBV) questions about your credit or financial history. You need to answer at least three of four correctly to prove you are who you say you are. If you have ever had a name change (a marriage, a divorce, a legal name change), have that document handy too, so I can verify the chain between the name on your ID and the name on the custody agreement.

The Other Parent Does NOT Need to Be Present Here is a point that surprises people: for an acknowledgment, only the person signing needs to be before the notary. If you are both parents signing the same custody agreement, you can each do your own RON session with me on the same day, back to back, each in your own home. You do not need to be in the same room as the other parent. Each of you separately proves your own identity and signs your own copy of the agreement. This is a genuine advantage of RON, especially when the two of you do not want to share a room for an hour.
Be Physically Inside New York State New York law requires that the signer be physically located in New York State at the time of the RON session. If you are at your family’s summer home in Lake Placid, you are in New York. If you are visiting a relative in Pennsylvania for the weekend, you are not. Plan our session for a day you know you will be in the state. This rule has caught more parents off guard than any other, so I will always confirm your location before we start.

Part 4: Step by Step, What Happens in Our RON Session

Let me walk you through exactly what you will experience, so there are no surprises.

Step 1. Scheduling and Pre-Session Prep. You book me through my booking system. I will send you a short checklist the day before. Find a quiet room with good lighting and a stable internet connection. Have your ID and the custody agreement in front of you.

Step 2. Credible Identification. I will ask you to hold your ID up to the camera. I will scan it to read the data, and then I will ask the KBV questions. If your ID and KBV answers check out, your identity is established. This is the RON replacement for the traditional “show me your ID and I will look at your face” in-person step.

Step 3. You Sign the Agreement. You will show me the fully completed custody agreement, then sign it on camera, on my watch, exactly where you would sign it in a physical notary’s office. If the agreement has multiple copies and both parents are signing, each parent signs their own copy during their own session.

Step 4. I Attach the Notarial Certificate. I will affix a digital notarial certificate to the document stating the date of your signature, my name and commission expiration, a statement that you acknowledged the signature as yours, and my electronic seal (eSeal). For a custody agreement, this certificate will be an acknowledgment, not a jurat, unless you are signing an affidavit.

Step 5. Delivery and Recording. Immediately after the session, the entire video recording is saved to a secure cloud for a minimum of five years, as New York law requires. You will receive the notarized custody agreement as a PDF by email, which you can print, share with your attorney, file with the court, or hand to a school or grandparent.

The whole session typically takes 15 to 25 minutes.

Part 5: Common Mistakes and How to Avoid Them

I have watched parents fumble these same things for years, so let me save you the frustration.

Filling in blanks at the last minute. Sign only after the document is fully complete. A notary who sees a half-filled agreement should tell you to go back and finish it. If I see blanks, I will ask you to stop, finish them, and then sign.
Assuming the notary will read the document. I am not reading your schedule. I am witnessing your signature. If the parenting time you agreed to is the wrong number of weekends, that is a drafting issue, not a notarial one. Have your attorney or mediator confirm the terms before we sign.
Signing before your ID is verified. Do not sign your agreement until I have confirmed your identity on camera. Once you sign, I am witnessing that specific act.
Forgetting you must be in New York. Confirm your location before the call. A “just in New Jersey for a family weekend” is not a New York RON session.
Confusing acknowledgment with jurat. Tell me up front whether your document is an agreement or an affidavit so I perform the right act.
Notarizing a copy you cannot compare to the original. If you are having me certify a copy of the custody agreement as a true copy, I need to see the original document you are copying from. I cannot certify a copy of a copy.

Part 6: Frequently Asked Questions

Q: If we are not in court, does our notarized custody agreement have the same power as a court order? A: Not quite. A notarized agreement is a strong, enforceable written contract between the two of you, and it is very persuasive to a court. But it does not have the automatic enforcement power of a court order, which can be enforced through contempt. Many parents start with a notarized agreement and, if things go well, keep it that way. If things go poorly, the agreement is often submitted to a Family Court judge, who can adopt it as an order. That is one of the great things about starting on paper.

Q: Do both parents have to notarize? A: Each parent who signs needs to sign before a notary (me, in RON). You do not need to be in the same room. You can each do your own session.

Q: What if the other parent refuses to sign the notarial act? A: Then their copy of the agreement is simply not notarized. Their signature is still valid between the two of you, but it is not notarized. If you want a fully notarized, court-ready document, both signatures need to be acknowledged. If the other parent refuses, you may need to have a court make the agreement enforceable, or you may rely on your own notarized signature plus a copy of their signed, non-notarized version.

Q: How long does a notarized custody agreement stay valid? A: The notarization itself does not expire. It is a permanent record that you signed on a certain date before a notary. The agreement’s terms, however, are always subject to modification by a court if the child’s best interests change, so treat the notarization as a snapshot in time, not a lifetime guarantee.

Q: Can I notarize a custody agreement if I live in another state? A: If you are physically outside New York at the time of the session, you will need a notary licensed in the state where you actually are. My RON session is only valid while you are in New York State.

Q: What is the fee? A: For a remote online notarization in New York, the fee is up to $25 per notarial act, which is what I charge, covering the technology and the convenience. If you do it in person at a traditional notary’s office, the acknowledgment is up to $2 per signature.

Final Thoughts

A child custody agreement is one of the most personal documents a parent will ever sign. It is also, for many parents, the first time they have encountered the quiet, procedural question of “does this need a notary?” The answer is not always yes, and it is not always no. What I can promise you is that when it does need one, the process is short, the technology is modern, and the result is a signature you can stand behind for years.

If you have a custody agreement in front of you and you are wondering what to do next, my advice is simple: confirm that the document is fully complete, have your ID ready, make sure you are physically in New York State, and book a remote session. I will walk you through the acknowledgment, verify your identity, and hand you back a notarized, court-ready document.
