The Third Department determined the county had the power to amend tax maps without notice and a hearing. Here the director of real property tax services amended a tax map to list the Steger Trust as the current owner of a 25 acre lot previously listed as the petitioner's property. The Third Department explained the county's powers in this regard, noted that a tax map merely identifies property, does not determine ownership and an action to quiet title is the appropriate remedy:
The County correctly asserts that the Director of Real Property Tax Services has the statutory authority to amend tax maps and to provide information about such amendments to the Town's assessor. Counties are required to prepare and maintain tax maps for each city and town therein, and it is the duty of the assessors to use such maps in assessment administration (see RPTL 503  [a]; 1532  [a]). As part of this responsibility, county directors of real property tax services are required to make “such changes from year to year upon such tax maps as may be necessary to maintain the maps in current condition” (RPTL 503 ; see 20 NYCRR 8189.14 [a] ; [c] ; 8189.16 [b]), and to advise assessors on the preparation and maintenance of assessment rolls and property record cards, among other things (see RPTL 1532  [c]). Based on this authority, the County properly amended its tax map and provided the updated information to the assessor listing the Steger Trust as the current reputed owner.
Also, contrary to petitioners' claim, the County did not determine that they do not own the parcel. Rather, the listing of the reputed owner on the tax map is only for the purpose of identifying the assessed property … . Likewise, because title to the property is not determined by the tax map, petitioners have failed to identify any protected property interest giving rise to procedural due process protection … . Any ongoing dispute between petitioners and the Steger Trust should be resolved in an action to quiet title pursuant to RPAPL [Real Property Actions and Proceedings Law] article 15… .
