Privacy note

These guides use generic examples only. They do not include client names, case names, file numbers, private property addresses, or facts from any private matter.

Why ET-117 comes up during estate work

ET-117 often comes up when an estate is selling or transferring inherited property and a title company needs proof that the estate tax lien has been released.

This guide is general information, not tax or legal advice. Estate tax questions can affect closings, fiduciary liability, and title. Use current New York Tax Department instructions and get professional review when needed.

What ET-117 does

When a person dies, New York law can place an estate tax lien on real property located in New York. The release of lien authorizes transfer of the property free and clear of that estate tax lien.

The release is about the estate tax lien, not every possible mortgage, judgment, Medicaid claim, creditor claim, or title issue.

When a release may be required

A release of lien may be required when a decedent owned New York real property or a cooperative apartment and the property is being transferred or sold. The Tax Department's public guidance says whether a release is required does not depend on the value of the property.

There are exceptions and fact-specific rules. For example, the Tax Department describes an exception involving property held by the decedent and surviving spouse as the only joint tenants. Confirm the current rule before assuming no release is needed.

Information usually needed

  • Decedent's full legal name.
  • Date of death.
  • County of residence at death.
  • Estate representative's mailing address.
  • Letters Testamentary or Letters of Administration, if issued.
  • Death certificate.
  • Deed and property tax bill.
  • County where the property is located.
  • Section, block, lot, liber, page, map, or other recorded-deed information.
  • Property address.
  • Co-op corporation information, if the asset is a co-op.
  • Estate tax return or certification information, if applicable.

Timing and closings

The Tax Department states there is no fee for a release of lien. It also warns not to schedule a closing until the stamped release is received if a release is required.

Public guidance lists an average processing time of three to four weeks for a complete application, plus mailing time. Incomplete forms, missing attachments, wrong property details, or unpaid tax assessments can add delay.

For estate real estate sales, ET-117 should be handled early. Waiting until the title company raises it right before closing can put the transaction at risk.

Common mistakes

  • The form was sent without the required companion form.
  • The wrong companion form was selected.
  • The property description does not match the deed or tax bill.
  • The return mailing address is wrong or illegible.
  • Letters were required but not attached.
  • The estate tax return status was unclear.
  • One form was used for property that requires separate releases.
  • The estate waited too long to request the release before closing.
