If your landlord just asked you to provide a notarized letter and you’re not sure what that means, you’re not alone. Most renters have never dealt with one until it shows up as a requirement during an application or lease signing.
A notarized letter for an apartment is any signed document that has been verified by a notary public. The notary checks your photo ID, watches you sign, and stamps the document to confirm the signature is authentic. It is not a complicated process, but there are a few things you need to know before you write one, including which type of letter your landlord actually wants.
What Is a Notarized Letter for an Apartment?
A notarized letter for an apartment is a signed document verified by a notary public. The notary checks the signer’s photo ID, witnesses the signature, and affixes an official seal. This process gives the letter legal weight and confirms that the information is authentic. Landlords most often require them for proof of residency, guarantor forms, and co-signer agreements.
What the Notary Actually Does
A notary public is a state-commissioned official authorized to verify identity and witness signatures on legal documents. When you bring your letter to a notary, they check a government-issued ID to confirm you are who you say you are. Then they watch you sign the document, making sure you are doing so willingly. After that, they record the transaction in their notary journal and stamp the document with their official seal.
That seal is what makes a letter “notarized.” It shows that a licensed third party has verified the signer’s identity and witnessed the process. Without it, the letter is a regular signed document with no independent verification behind it.
Why Landlords Ask for a Notarized Letter
Landlords request notarized letters primarily to reduce fraud risk. A notarized document is much harder to fake than a plain signed letter because a licensed official has verified the signer’s identity on the record. In competitive rental markets, some landlords also use notarized letters to confirm that all parties fully understand what they are agreeing to. If a dispute arises later, a notarized letter carries more legal credibility than one that is simply signed.
Types of Notarized Letters Landlords May Request
Most renters assume a notarized letter for an apartment means a proof of residency letter. In reality, there are four common types, and which one you need depends on what the landlord or property manager is trying to verify.
| Type of Letter | What It Proves | Who Signs It | When It Is Typically Required |
|---|---|---|---|
| Proof of Residency Letter | That you currently live at a stated address | Tenant or current landlord | School enrollment, government ID updates, license applications |
| Lease Guarantor / Co-Signer Letter | A third party will cover rent if the tenant cannot | Parent, relative, or other guarantor | Tenant has insufficient income or credit history |
| Income or Employment Verification Letter | Your income meets the rental threshold | Employer or self-employed tenant | Tenant is self-employed or paid outside of traditional payroll |
| Authorization Letter | You are giving someone permission to act on your behalf | Tenant | Subletting, authorizing repairs, allowing someone to collect mail |
Do You Actually Need a Notarized Letter to Rent an Apartment?
Not always. Most residential rental agreements in the United States do not legally require notarization to be valid. A standard lease is binding as long as both parties sign it and it meets basic contract requirements. Notarization is a layer of verification, not a legal requirement in most situations.
That said, there are specific circumstances where it is required or strongly advisable.
When Notarization Is Required by Law
Some states have rules about when lease-related documents must be notarized. Washington State requires that residential leases longer than one year be acknowledged by a notary to be legally valid, under RCW 59.18.210. Ohio law (Revised Code Section 5301.01) requires leases longer than three years to be signed in front of a notary and properly recorded. Louisiana also has specific notarization requirements for certain lease agreements.
If you are renting in a state with these requirements and your lease term crosses the applicable threshold, your landlord should make you aware of it. If you are unsure, reviewing your state’s landlord-tenant statute is worth the few minutes it takes.
When a Landlord May Ask for One Without a Legal Requirement
Outside of state law, landlords often request notarized letters based on their own internal policies. This is common in high-demand rental markets like New York City, where guarantor letters are frequently notarized to protect property owners from fraudulent applications. It also comes up when:
- A co-signer lives in another state and will not be present at the lease signing
- The tenant is self-employed and providing their own income verification
- A property management company has a blanket notarized-document policy for all applicants
- The rental is high-value and the landlord wants added security on all signed agreements
In these cases, the landlord is not legally required to demand notarization. But if they do, you will need to comply to move forward with the application.
How to Get a Notarized Letter for an Apartment
The process is straightforward. Here are the five steps:
- Write the letter. Include your full legal name, current address, the date, and a clear statement of purpose. If it is a proof of residency letter, state how long you have lived at the address. If it is a guarantor letter, state who you are guaranteeing and what you are agreeing to cover.
- Do not sign it yet. The notary must witness your actual signature. Signing before you arrive makes the document invalid for notarization purposes, and most notaries will ask you to start over.
- Find a notary public. Banks, credit unions, UPS and FedEx stores, public libraries, and courthouses all commonly have notaries available. You can also complete the process online using a remote notarization platform.
- Bring a valid, government-issued photo ID. A driver’s license, passport, or state-issued ID card will work. The National Notary Association requires that all commissioned notaries verify signer identity before proceeding with any notarial act.
- Sign in front of the notary. They will confirm your identity, watch you sign, record the transaction in their journal, and affix their official seal. The document is now notarized and ready to submit.
Most in-person notarizations take under 15 minutes once you arrive with your ID and unsigned document.

What to Include in a Notarized Letter for an Apartment
The specific content varies by letter type, but every notarized letter for an apartment needs to include the following:
- Full legal name of the signer
- Current mailing address
- Date the letter is signed
- A clear statement of purpose describing what the letter is certifying
- The signer’s handwritten signature, signed in front of the notary
- Space for the notary’s signature, official seal, and commission expiration date
Here is a basic proof of residency template you can adapt for your situation:
To Whom It May Concern,
I, [Full Legal Name], hereby certify that I currently reside at [Full Address], and have done so since [Move-In Date]. I am providing this letter as proof of my current residence for [State the Purpose].
I understand this statement is being made under penalty of perjury and that the information provided is accurate to the best of my knowledge.
Signed: ______________________
Date: ______________________
[Notary Public Seal and Commission Information]
If your landlord gave you a specific form to fill out, use their version rather than writing your own. The notarization process is the same either way.
Frequently Asked Questions
How much does it cost to get a letter notarized?
In-person notarization typically costs between $5 and $15 per signature, and many states cap the maximum fee notaries can charge by law. Some banks offer free notarization for account holders. Online notarization platforms generally charge $25 to $35 per session. The person requesting the notarization usually pays the fee.
Can a landlord legally require a notarized letter?
Yes. Landlords can set their own application requirements, including requiring that certain documents be notarized. As long as the requirement applies equally to all applicants and does not conflict with fair housing laws, landlords are within their rights to require notarized documentation as part of their rental process.
Does my lease agreement itself need to be notarized?
In most states, no. Standard residential leases are legally binding without notarization. A few states require it for leases above a certain length: Washington State for leases over one year, and Ohio for leases over three years. Check your state’s landlord-tenant law if you are unsure whether your specific lease triggers a notarization requirement.
What is the difference between a notarized letter and a regular letter?
A regular letter is a document that someone signed. A notarized letter was signed in front of a notary public who verified the signer’s identity, witnessed the signing, and stamped the document with their official seal. The seal creates a verifiable record that identity was confirmed, which gives the letter greater legal credibility in disputes, applications, and official proceedings.
Who can serve as a notary public?
A notary public is a person commissioned by their state government to perform notarial acts, including verifying identity and witnessing signatures. Notaries are not lawyers and cannot provide legal advice, but they are authorized state officials. Banks, shipping stores, and many government offices have notaries on staff. Commissioned notaries are also available through online platforms for remote sessions.
What happens if I submit a regular letter when a notarized one was required?
The landlord or property manager will typically reject the document and ask you to resubmit it with a notary seal. If you are on a deadline for a lease signing or rental application, this can cause delays that cost you the unit. Confirming exactly what the landlord needs before you submit saves time and avoids that situation entirely.
Can I notarize a letter myself?
No. A notary public cannot notarize their own documents or any document in which they have a personal interest. The notarization process requires an independent third party to verify identity and witness the signature. Even if you hold a notary commission yourself, you need a different notary to handle your own apartment-related letters.
Getting Your Letter Notarized Does Not Have to Be Complicated
A notarized letter for an apartment is simply a document a licensed official has verified. Whether you need a proof of residency letter, a guarantor form, or an income verification letter, the steps are the same: write the document, find a notary, bring your ID, and sign in front of them.
If you need it done quickly or your co-signer is not nearby, BlueNotary handles online notarization around the clock with no appointment needed. You can get your document verified and sealed in minutes, from wherever you are.
