Most agreements between a landlord and a tenant need no notary. The ones that end a tenancy, settle money, or trade something valuable for a signature are worth the extra formality, because those are the ones people later claim they never signed.
Here is which agreements those are and what belongs in them.
Same day across the five boroughs, evenings and weekends, or online in minutes when a party is out of state. Do not sign before the appointment. Book a notarization →
Surrender agreements
Where a tenancy ends by agreement rather than by expiry or eviction, the document recording it is the most consequential thing either side signs.
It should state the date the tenant will vacate, the condition the apartment will be left in, what happens to the security deposit, whether any rent is owed or forgiven, and that both sides release each other from further claims.
Notarize it. Both signatures. This is the document that gets disputed, and a verified signature ends most of that before it starts.
Buyouts, and the caution attached
In New York City a landlord may offer a tenant money to vacate, particularly in rent regulated apartments, and there are rules about how those offers may be made.
Tenants have protections against harassment in this context, and there are requirements around disclosure and the tenant’s right to seek counsel and to decline.
So the plain advice: do not sign a buyout without a lawyer. You are giving up a regulated tenancy that may be worth far more than the sum on the table, and it is not recoverable afterward.
A notary can verify the signature. A notary cannot tell you whether the number is fair, and this is a situation where that question is the entire question.
Payment plans and rent arrears
Common, useful and frequently done badly on a text message.
Put it in writing: the total owed, the installment amounts and dates, how payments are applied, and what happens if a payment is missed. Be specific about whether the landlord is agreeing to hold off on a proceeding and on what terms.
Both sides benefit from clarity here. A tenant gets a defined path, and a landlord gets an acknowledgment of the debt.
Notarizing is worth it where the sum is significant. And where a court proceeding already exists, any agreement should be handled through that proceeding rather than privately, which is a matter for the attorneys involved.
Lease modifications and side agreements
A permission to keep a pet, an agreed alteration to the apartment, an early termination, a change in who is on the lease, an agreement about repairs.
All of these end up as verbal understandings that evaporate when a building changes hands or a superintendent leaves.
Write them down, have both sides sign, and keep a copy. Notarization is optional and it is cheap certainty on anything you would be upset to lose.
Where notarization genuinely earns its place
Any document ending a tenancy. Any document involving money changing hands beyond the normal rent. Any agreement with somebody you do not expect to see again. Any signature made from another state, which is common with out of state owners.
Both parties do not have to attend together, and each can be handled separately, including online in minutes.
What a notarized agreement does not do
It does not make an unlawful term lawful. A clause waiving a right New York gives a tenant is not rescued by a seal.
It does not override rent regulation, and it does not turn a private deal into a court order.
And it does not mean anybody read the document to you. A notary verifies who signed. Understanding what you signed is your side of it, and where the stakes are real, that is what a housing attorney or a free tenant service is for.
See also the security deposit rules, which govern regardless of what any agreement says.
Small landlords and property managers
Owners of one or two buildings sign these agreements rarely enough to get them wrong and often enough for it to matter.
Three habits prevent most trouble. Put every arrangement in writing rather than agreeing on the phone. Use the same template each time so nothing is forgotten. And keep a file per unit rather than a drawer per building.
Where you manage several units, an outside notary who comes to you is usually faster than sending tenants out to find one, and getting both signatures in the same visit removes the classic problem of a document signed by one side and never returned by the other.
We handle multi unit signings on site across the five boroughs. See our business notary service.
Read before you sign, on either side
The pattern we see at signings is a document produced quickly, under pressure, at the end of a difficult conversation.
Slow down for ten minutes. Check the dates, the amounts and the release language. Check whether you are giving up a claim, a tenancy or a deposit. Check that nothing is blank.
A notary will decline to notarize a document with blanks in it, and will stop a signing where somebody plainly does not understand what they are agreeing to. If that happens, it is not an obstacle; it is the safeguard doing its job.
Keep the executed copy
Both sides should leave with a fully signed original, not a promise that a scan will follow.
Photograph it before you part. Agreements about tenancies surface years later, in a deposit dispute, a housing court matter or a sale of the building, and the version somebody can produce is the version that counts.
If you are being pressured to sign
Worth its own section, because it is the situation that produces the worst outcomes in this area.
A tenant presented with an agreement at the door, told it must be signed today, offered cash on the spot, or told they will be evicted if they do not sign, is being pressured. That is true whether or not anybody raised their voice.
You are entitled to take the document away, read it, and get advice. You are entitled to say no. And in a rent regulated apartment in New York City, the protections around buyout offers exist precisely because this pressure is common.
A notary is required to be satisfied that a signature is knowing and voluntary. If we see that it is not, we will stop, and we would rather do that than complete a document you will regret.
Free tenant legal services exist across the city. Use them before signing, not after.
Get it in writing even when relations are good
Most landlord and tenant relationships in New York are perfectly civil, and the paperwork feels unnecessary precisely while it is easy to do.
Write it down anyway. Buildings change hands, superintendents move on, management companies are replaced, and the person who agreed to something verbally is frequently not the person you are dealing with two years later.
A one page signed note recording what was agreed, dated, kept by both sides, costs nothing and settles the question permanently. It is the cheapest insurance available in a tenancy, and neither side regrets having it.
