Statutory Research Checklist

Updated Oct. 29, 2012.
Prepared by Cheryl Nyberg; updated by Andrew Martineau (2012) and Jackie Woodside (2009).

Statutes are laws enacted by legislatures, like the U.S. Congress and the Washington State Legislature. See Free Law Online for links to free sources of statutes for Washington and other U.S. statutes.

Preliminary Analysis

Conduct preliminary analysis to determine:

  • Jurisdiction: federal or state
  • Keywords: search terms that you will use to describe the legal question
  • Time period: current law or law in force at some time in the past

Secondary Sources

Consult secondary sources (law reviews, encyclopedias, hornbooks, nutshells, deskbooks, etc.) to learn more about the topic. These sources often provide citations to relevant statutes or to the popular name of the statute.

  • If you find a statutory citation, read the statute but continue the research process. There may be other statutes that affect your issue.
  • If you find a reference to the popular name of the law, consult the popular name table included in many (but not all) statutory codes.
  • Review the Gallagher guide on Secondary Sources for more information.


Subject Indexes & Popular Name Tables

Use the subject index and/or the popular name table for the appropriate statutory code.

  • Indexes are found at the end of the print set; most indexes are multi-volume. Westlaw contains indexes for the U.S. Code and for state statutes. LexisNexis does not.
  • The Office of Law Revision Counsel provides a US Code Popular Name Tool.
  • Start with specific terms and proceed to more general terms.
  • Use synonyms and alternative expressions (for example, "dissolution of marriage" as well as "divorce").
  • Be creative, flexible, and persistent but remember: not all legal issues are governed by statute. Go back to secondary sources if you fail to find an appropriate statute.
  • Record the subject headings you have searched and any likely statutory citations. Keeping a record will help you do efficient and effective research.
  • If you know the popular name of a law (such as the Americans with Disabilities Act or the Growth Management Act), look for the popular names table that is located with the indexes. LexisNexis and Westlaw include popular name tables for federal statutes.


Online Keyword Search

Online Sources: Search by keywords.

  • Searching for statutes online can be difficult. You have to anticipate the language used by the legislature in writing the law.
  • Use truncation, wild-cards, and Boolean searching to improve your results.
  • Search the online index to statutes, if one is available. The index will provide cross-references to preferred terms and synonyms.


Read & Browse the Statute

  1. Read the statute to determine if it does indeed cover the legal issue you are researching.
  2. Browse the chapter or title outline to see if other sections may also be pertinent.
  • Many modern statutes include a purpose or legislative findings statement. Reading these sections may help you understand why the legislature enacted the law.
  • Look for a definitions sections. Often the legislature will provide a list of definitions of words or phrases used in a law. Those definitions may vary from commonly accepted definitions.


Print Sources

  • Check the pocket part in the back of the volume or the cumulative supplement. These supplements are usually published annually.
  • Look for legislative service pamphlets. These updates are published throughout the year and usually include a cumulative list of statutes affected by recently enacted laws and a cumulative subject index.
  • Record the dates of the pocket parts, cumulative supplements, and/or legislative service pamphlets that you use.

Online Sources

  • Check the currency note at the beginning of the document.
  • Note that not all online sources are up-to-the-minute. Some sources on the Internet may be more out-of-date than comparable print tools. LexisNexis and Westlaw are, however, more current than print sources.
  • On Westlaw, use KeyCite to identify pending legislation that might affect the statute.


Review Annotations

Look at the annotations to the statute(s).

  • Annotations include a history of the law (when it was originally enacted and subsequently amended) and references to court decisions that have applied or interpreted the statute, law review articles that focus on the statute, and other material.
  • Use the annotations to continue your research for mandatory and persuasive precedent (court cases).
