How to Find and Cite New Jersey Law

In New Jersey, an agency rule expires on its own. Seven years after a chapter of the Administrative Code takes effect it's gone, unless somebody files to keep it.

That comes straight out of N.J.S.A. 52:14B-5.1, and the expiration date gets printed with the rule. So every New Jersey regulation carries a second question alongside what it says. How long does it have left?

Who publishes what

Statutes come from the Legislature. Under N.J.S.A. 52:11-78 the Office of Legislative Services puts the full text online for free, and describes it as the most current official text of the permanent and general statutes of New Jersey available without charge to the public. Enacted laws are chaptered by year, which is why a session law cite looks like L. 1961, c. 5, § 1.

Regulations come from somewhere else entirely. N.J.S.A. 52:14B-7 puts the Office of Administrative Law in charge of the New Jersey Administrative Code, and says the director shall compile, index and publish it containing all effective rules adopted by each agency, and that the Code stays under the control and direction of that office regardless of the method or medium used to store, maintain or distribute it.

The same section makes the New Jersey Register the update vehicle, published at least monthly, and makes the director publish a filing schedule a year ahead. The 2026 schedule runs 24 issues, on the first and third Monday of the month, sliding to Tuesday when a holiday is in the way. Each issue has a proposal deadline and an adoption deadline weeks earlier. To land in the October 5, 2026 issue, an adoption had to be at the office by noon on September 11.

One more piece of that section is worth knowing if you build anything that stores rule numbers. The director may number or renumber parts and sections, divide them, combine them, and remove expired rules after notice to the agency head. What the director may not do is change the language of a rule, other than a title or caption. Addresses can move. Text can't be touched.

The two citation forms look alike and don't line up

The state judiciary's own style manual for opinions is blunt about statutes. Cite them as N.J.S.A., not R.S. and not N.J.S., with no section symbol, and include a date only when it matters: N.J.S.A. 2C:43-6(c) (2013). For a whole act use a range, N.J.S.A. 17:10-1 to -26, rather than et seq.

There's an odd wrinkle underneath that. The statute governing citation, R.S. 1:1-5.1, says R.S. is equivalent to Revised Statutes and N.J.S. is equivalent to New Jersey Statutes, and that sections may be cited by number preceded by either. Which means the two abbreviations the courts tell you to skip are the two the statute itself names, and the one the courts want is the abbreviation of a commercially annotated edition.

Regulations take the same shape with a decimal on the end: N.J.A.C. 12:18-2.27. Title, chapter, section. Register cites carry a letter that picks out which notice on the page you mean: 46 N.J.R. 77(a) (Jan. 6, 2014).

And the two sets of title numbers have nothing to do with each other. N.J.A.C. Title 7 is Environmental Protection, and the noise rules at N.J.A.C. 7:29 are written under the Noise Control Act at N.J.S.A. 13:1G-1 and following, over in Title 13. So a bare number with a colon in it could belong to either book, and matching the number across books gets you nowhere. Read the authority line on the rule.

What the corpus looks like

These counts come from a US primary law corpus maintained by Vaquill AI, measured on 2026-09-18. New Jersey holds 111,746 sections.

• Statutes: 55,987
• Regulations: 53,319
• Court rules: 1,685
• Agency guidance: 523
• Constitution: 216
• Attorney General opinions: 16

Now look at the statuses on the regulation side. 45,918 in force, 5,069 reserved, 2,295 unknown, and 37 repealed. Thirty-seven, across a body of 53,319 sections.

That number is small because repeal isn't how a New Jersey rule usually ends. Expiry is. A chapter nobody readopts simply stops, and nothing has to be struck out of the book for that to happen.

The statutes run the other way. 55,984 of 55,987 sections are in force, with 3 reserved. The compilation carries current text and very little history, so if you need to know what a section used to say, you go to the session laws rather than to the statute page.

A rule with a date on it

Take N.J.A.C. 7:29, the noise control rules.

They were scheduled to expire on April 11, 2026. On February 17, 2026 the Department of Environmental Protection filed a notice of readoption, saying it had reviewed the rules and found them still necessary, reasonable and proper. The notice ran in the March 16, 2026 Register, and the new expiration date became February 17, 2033.

Look at what those dates did. Filing on time under N.J.S.A. 52:14B-5.1 extends the chapter seven years from the date of filing, not seven years from the date it would have expired. The department filed about two months early, so the next deadline landed in February 2033 rather than April. Small thing, but if you're tracking when a chapter comes up again, the filing date is the date that counts.

Readopting with substantive changes works differently. There the agency proposes the readoption before expiry, and that filing buys a 180 day extension to finish the job.

What else catches people

The free online Code is not the official Code, and the office says so on its own public access page. If a number matters, check it against the official version.

Court rules run on a separate annual cycle. The Supreme Court signs an omnibus order in the summer and the amendments take effect on September 1. The 2023 order was dated August 4 and adopted its amendments to be effective September 1, 2023, and the pattern has held for decades. A brief written in August can quote a rule that changes a few weeks later.

Then there's the mismatch between how the state writes and how its courts write. The Environmental Protection notice cites its own authority as N.J.S.A. 13:1G-1 et seq., which is exactly the form the judiciary's style manual tells you not to use. Both are correct in their own house. Just don't copy a range out of a Register notice into a brief without reshaping it.

If a chapter's expiration date has already gone by and no readoption was filed, the text you're reading stopped being a rule on that date.
