N.J. Stat. § 2A:61-1
When any sheriff, coroner, master, executor, administrator, guardian, commissioner, auditor or other officer or person is authorized or required by any public statute or the direction of any court of competent jurisdiction in this State to make sales of real estate, he shall, unless otherwise specially directed or authorized by law, before making the sale, give notice of the time and place of the sale by public advertisement, signed by himself, and set up in the office of the sheriff of the county or counties where the real estate is located and at the premises to be sold, at least 3 weeks before the time appointed for the sale. The notice need not be set up at any other place. The notice of sale shall include either a diagram of the premises or a concise statement indicating the municipality, the tax lot and block and where appropriate, the street and street number, and the dimensions of the premises, as well as the number of feet to the nearest cross street. The notice of sale shall state that the diagram or concise description does not constitute a full legal description of the premises, and shall state where the full legal description can be found.
Such officer or person shall also cause the notice to be published 4 times, at least once a week, during 4 consecutive weeks, in two newspapers, to be by him designated,
The first publication shall be at least 21 days prior and the last publication not more than 8 days prior to the time appointed for the sale of the real estate.
Whenever, in the opinion of any such officer or person, the ends of justice shall require it, or the sale being conducted by him will be benefited thereby, the notice of sale may be published in three newspapers instead of two as required by the second paragraph of this section, if there be that number printed and published in the county where the real estate to be sold is located.
The officer or person so advertising in the newspapers shall be entitled therefor, in addition to his other fees, to the sum of $1.50, except where it is otherwise specifically provided.
