The most advanced way to pinpoint exact historical versions of statutes

Board a virtual time machine to look back at a statute and see how it's changed

When a legal issue arises, it's not the current code that matters. What was the law when your client's offense, transaction, injury, or other legal matter took place? Statutes are constantly amended, revised, overruled, and superseded, making it difficult to track down an exact historical version. For instant answers, use PastStat Locator, a fast, reliable way to see how a statute existed on a particular date, and how it has evolved.

Renumbered statutes? Future effective dates? No problem.
  • Track renumbered statute sections to see how a statute has changed and which code section took its place
  • Learn when a statute or amendment is due to take effect or lapse

Choose from a unique collection of legislative history for select states

Content, which varies by state, may include:
  • Statutes, slip laws, and session laws
  • Bill summaries and full texts, amendments and versions
