Two parents agree on something, write it down, and have it notarized because that feels like what makes it official. It is worth understanding exactly what that achieves, because it is both more and less than people assume.
Notarization proves who signed. It does not make an agreement enforceable, and where children are concerned, it does not bind a court.

What the notarization actually gives you
Evidence. A verified identity, a date, and an impartial officer’s certificate that this person signed this document willingly.
That is genuinely useful. It makes it very difficult for either parent to later claim they never signed, that the signature is forged, or that the document was created afterward.
In an informal arrangement between parents who are otherwise getting along, that is often all anybody needs, and it settles most disagreements about what was agreed.
What it does not give you
Enforceability by itself. A notarized page is not a court order, and neither parent can take it to a police station or a court clerk and have it enforced on the spot.
Authority over custody. Courts decide custody and parenting time based on the best interests of the child, and they are not bound by a private agreement, however carefully it was drafted or how formally it was signed.
Finality on child support. Support is governed by statute, and parents cannot simply agree between themselves to a figure or to none at all in a way that binds anybody permanently, particularly where public benefits are involved.
A change to an existing order. If a court order exists, a private agreement does not modify it. Only the court can.
That last point is where people get hurt
It comes up constantly and it is worth stating clearly.
Two parents have a custody or support order. Circumstances change, they agree informally to something different, they write it down and have it notarized, and they operate that way for two years.
Then the relationship sours, and one of them enforces the original order. Arrears may have accrued under the order the whole time, regardless of what the parents agreed privately, and the notarized document may not undo that.
If an order exists and you want it changed, the change has to go through the court. That is inconvenient and it is the only route that actually protects both parents.
Where a written agreement does help
Plenty of situations, and they are worth naming so this does not read as discouragement.
Parents with no court order who want a clear record of the schedule they have agreed. A one off arrangement, such as a holiday, a trip, or a change of school. Confirming who pays for a specific expense. Documenting an agreement that will later be submitted to a court as the basis for a consent order.
In each case the document creates clarity and evidence, which prevents most disputes before they start.
Do it properly if you do it
Be specific. Dates, times, locations, amounts, who does the driving, what happens if somebody is late. Vagueness is what produces the next argument.
Both parents sign, and both signatures are notarized. They do not have to attend together, and each can be handled separately, including online, which is frequently the point where one parent lives elsewhere.
Each keeps a fully signed copy. An agreement only one parent can produce is worth much less.
When to involve a lawyer instead
Any existing court order. Any disagreement about custody or relocation. Any question about support amounts. Any situation involving safety, or where one parent feels pressured.
A notary cannot advise on any of it, and a family lawyer consultation is far cheaper than the version where this goes wrong. We notarize what you bring us and we will tell you plainly when what you are describing needs somebody else.
Turning an agreement into something enforceable
If you want the arrangement to actually stick, the route is a court order, and parents who agree can usually get one without a fight.
Where both parents consent, a court can be asked to make the agreed terms an order, sometimes called a consent order or a stipulation. It is far quicker and cheaper than a contested proceeding, because there is nothing to argue about.
The written agreement you already have becomes the basis for it, which is a good reason to have written it carefully.
That is the sequence worth knowing: agree, write it down, notarize it, then have it made an order. Each step is cheap. Skipping the last one is what leaves people exposed.
What to include, practically
The regular schedule, in dates and times rather than in general terms. Holidays, birthdays and school breaks, named specifically, because those are the flashpoints.
Who collects and drops off, from where, and what happens if somebody is late or a child is unwell.
How decisions about school and medical care are made, and who is consulted.
Money: what each parent pays for, and how expenses outside the ordinary are split.
How the agreement gets changed, and how the parents will communicate.
Write it as though you will not be on speaking terms when it is read, because that is when it will be read.
Keep the tone out of it
A tempting mistake in a document that is really about a relationship.
Leave out grievances, characterizations of the other parent, and anything written to make a point. Those lines feel satisfying and they do real damage if the document is ever shown to a court or read by a child.
Facts, dates, amounts and arrangements. Nothing else.
Where a notary will stop
Family documents are the ones where we most often decline, and it is worth knowing why in advance.
If one parent appears to be signing under pressure, if the other is answering questions for them, or if a signer plainly does not understand what they are agreeing to, we will not proceed. New York’s rules allow a notary to refuse where they are not satisfied the signature is knowing and voluntary, and this is exactly the situation that provision is for.
We will also decline to notarize a document with blank spaces, or to notarize a signature that was made before the appointment.
None of that is a judgment about your family. A document signed under pressure is a document that gets challenged, and the challenge lands on both parents.
If safety is a factor
Where there has been violence, threats or coercive control, a private notarized agreement is the wrong instrument, and meeting to sign one may not be safe.
That situation needs a family law attorney and, where appropriate, the court’s protective processes. There are free and low cost legal services across New York City that handle exactly this, and a court order carries protections a private agreement cannot.
Please do not let paperwork convenience decide that question.
