New York Affidavit of Heirship Form Instructions for Surrogate's Court Filing

When someone passes away in New York without a will, figuring out who legally inherits their property can get complicated fast. An affidavit of heirship is the document that lays out, under oath, exactly who the surviving family members are. If you've been told you need to complete this form or if you're trying to transfer real estate, bank accounts, or other assets left behind by a relative understanding how to fill it out correctly the first time can save you months of delay and hundreds of dollars in legal fees.

What Is an Affidavit of Heirship in New York?

An affidavit of heirship is a sworn legal statement that identifies the deceased person's heirs their spouse, children, parents, siblings, or other relatives who have a legal right to inherit. It is used in New York when someone dies without a valid will (intestate) and their estate needs to pass to the rightful heirs under New York's intestacy laws.

The person signing the affidavit called the "affiant" swears under oath that the information about the family relationships is true. In New York, this affidavit is typically filed with the Surrogate's Court in the county where the decedent lived.

This document is not the same as probating a will. It applies specifically when there is no will or when property needs to be transferred through intestate succession.

When Would You Need to File an Affidavit of Heirship?

You might need this form in several situations:

Transferring real property: If the deceased owned a home, land, or other real estate and had no will, the affidavit helps establish who can sell or transfer the property.
Accessing bank accounts or financial assets: Some banks and financial institutions require proof of heirship before releasing funds.
Small estate proceedings: When the estate is valued under $50,000 (excluding real property), an affidavit of heirship may be part of the small estate filing process at Surrogate's Court.
Establishing a chain of title: Title companies sometimes require an affidavit of heirship to clear title issues on inherited real estate.

What Information Do You Need to Complete the Form?

Before you sit down to fill out the affidavit, gather the following:

Full legal name of the deceased person (the decedent)
Date and place of death you'll need the death certificate
Last known address of the decedent
Marital history whether the decedent was married, divorced, or widowed, and the names of any surviving or former spouses
Complete list of children including full names, dates of birth, and whether any children predeceased the decedent (if so, you'll need their children's names too)
Parents' names especially relevant if the decedent had no surviving spouse or children
Siblings' names if applicable under intestacy rules
Description of the property or assets involved
Two disinterested witnesses people who knew the family but have no financial interest in the estate

How to Fill Out the New York Affidavit of Heirship Step by Step

Step 1: Identify Yourself as the Affiant

At the top of the form, write your full legal name, address, and your relationship to the deceased. You must be someone with personal knowledge of the family typically a close relative, longtime friend, or someone who knew the decedent well.

Step 2: State the Decedent's Information

Provide the full name, date of death, and last address of the person who passed away. Attach a certified copy of the death certificate if required by the court.

Step 3: List All Heirs Under New York Intestacy Law

New York's Estates, Powers and Trusts Law (EPTL) § 4-1.1 sets out who inherits when there's no will. The priority generally follows this order:

Spouse and children
Parents
Siblings
Grandparents, aunts, uncles, and cousins

List every person who qualifies as an heir. Do not leave anyone out even if you believe they won't claim their share.

Step 4: Describe the Property

Include a clear description of the estate property. For real estate, provide the property address and, if available, the tax lot and block number. For financial assets, name the institution and account type.

Step 5: Sign Under Oath Before a Notary

The affidavit must be signed in front of a notary public. The two disinterested witnesses must also sign, attesting that they personally knew the decedent and can confirm the family information is accurate.

Step 6: File with the Surrogate's Court

File the completed affidavit with the Surrogate's Court in the appropriate county. Some counties may require additional supporting documents, so check with the court clerk before submitting.

What Are the Most Common Mistakes People Make?

Leaving out heirs: If you skip a known heir even one who lives out of state or hasn't spoken to the family in years the affidavit can be challenged and voided.
Using witnesses with a financial interest: The witnesses must be disinterested. A person who stands to inherit cannot serve as a witness.
Not getting the affidavit notarized: An unsigned or un-notarized affidavit has no legal weight.
Confusing joint property with estate property: Property held in joint tenancy or with a named beneficiary typically passes outside the estate. The affidavit of heirship applies to property that passes through intestate succession.
Filing in the wrong county: The affidavit should be filed in the county where the decedent was domiciled at the time of death, not where the property is located.

Does an Affidavit of Heirship Replace Probate?

No. An affidavit of heirship does not replace probate or letters of administration. If the estate involves significant assets, debts, or disputes, you may need to go through the full Surrogate's Court probate process or apply for letters of administration. The affidavit is a supporting document it helps establish heirship, but it does not by itself grant authority to distribute the estate.

For smaller estates without real property, the affidavit may be enough when combined with a small estate affidavit under SCPA § 1304. For estates with real property, the Surrogate's Court will typically need to issue letters of administration before any transfer can happen.

How Much Does It Cost to File?

Filing fees in New York Surrogate's Court vary by county but generally range from $1 to $75 for most estate filings. You may also need to pay for:

A certified copy of the death certificate (around $15–$30 per copy)
Notary fees (usually $2–$10 per signature)
Legal consultation if you hire an attorney to prepare or review the affidavit

Can You Complete the Affidavit Without a Lawyer?

Yes, many people handle straightforward affidavits of heirship on their own, especially when the family situation is uncomplicated no disputes, no stepchildren, no missing relatives. The small estate proceeding guide covers similar ground for cases under the $50,000 threshold.

However, if the estate involves multiple marriages, estranged family members, property in more than one state, or potential disputes, hiring an experienced New York estate attorney is worth the investment. A rejected or challenged affidavit can delay inheritance for months or even years.
