New Jersey Statutes Title 22A. Fees and Costs 22A § 2-31

Whenever it shall appear that the estate, real and personal, of any testator, intestate, minor or ward, is less than one hundred dollars ($100.00), no fees shall be charged upon actions for probate of a will, granting administration or guardianship up to and including the letters issued and copies of such letters as well as the fees of filing and recording and with respect to an inventory, and whenever it shall appear that such estate does not exceed two hundred dollars ($200.00) the fees shall be one-half of those allowed by law; but if it shall afterwards appear in any case that the value of the estate, real and personal, exceeds or exceeded two hundred dollars ($200.00), then such estate shall be liable for and pay the balance of the fees that would have been collected had no deduction been made under the provisions of this section.
