New Jersey Statutes Title 54. Taxation 54 § 5-114.10

Any purchaser of a tax sale certificate under the act to which this act is a supplement, or his assignee, who has heretofore or who shall hereafter foreclose said tax sale certificate within the time in which he was or shall be required to foreclose the equity of redemption and record the final judgment or decree, or otherwise has or shall have complied with the conditions appertaining to his said purchase but who has or shall have failed to fully foreclose the said equity of redemption by reason of the inadvertent omission of a party or parties who had or shall have an interest in the property affected by said tax sale certificate, shall have the right to bring an action to foreclose the said omitted party or parties from his or their equity of redemption or interest in said property, either by an action in the nature of strict foreclosure or reforeclosure, or similar action. In lieu of any such action the purchaser may acquire any outstanding unforeclosed interest or obtain a cancellation thereof by release, discharge or otherwise. In the case of any such omission, the original foreclosure action or proceeding shall be deemed a substantial compliance with the act to which this act is a supplement, notwithstanding the omission. The bringing of a subsequent action or the acquisition or cancellation of an unforeclosed outstanding interest, under the provisions of this section shall in nowise invalidate the rights of the purchaser or his assignee in and to the said tax sale certificate.
