N.J. Stat. § 40:56-56
Except as provided in article four of this chapter (s. 40:56-58 et seq.) as to cities of the first class, the owner of any real estate or interest therein taken for any improvement mentioned in this chapter may appeal to the Superior Court from the award of damages made for the taking of such property as distinguished from the award for damages incidental to this improvement. The appeal shall be taken within thirty days after confirmation of the assessment or award appealed from by serving a written notice thereof within said thirty days upon the clerk or the chief executive officer of the municipality, either personally, or by leaving the same at his office or place of abode.
An appeal taken pursuant to this section shall not affect the validity and commencement of a lien against land that has been assessed for benefits, but shall be considered to affect only the amount of the lien.
