California legal research is not too different from legal research in other states. However, there are some California-specific secondary sources, including treatises and practice guides, that are frequently used by practicing lawyers. These resources are discussed below.
To provide feedback on this guide, please contact its author, Research Librarian Jennifer Allison (email@example.com).
The Harvard Law Library has California legal materials both in both print and electronic formats.
In the Harvard Library catalog, Hollis, many materials related to California law have been assigned the Library of Congress subject heading "Law -- California" -- click the link to view these items in Hollis.
Note that several subscription databases, including Westlaw and Lexis, include a large amount of California legal materials. The law library provides access to these databases for Harvard Law affiliates. In addition, a public Westlaw terminal is available in the library for anyone with access to the library to use. For more information about library access, visit the Access Services homepage.
Like the federal government, California's legislative branch features a bi-cameral legislature: the Senate and the Assembly. An identical version of a bill must pass in both the Senate and the Assembly and be signed by the Governor to become law.
Both of the executive and legislative branch offices are located in the state capital, Sacramento.
In California's judicial branch, the trial-level court is called the Superior Court. It hears both civil and criminal cases. There are also two levels of appellate courts, just like the federal system: the Court of Appeal and the Supreme Court.
Legal researchers in California are lucky to have a large selection of state-specific secondary sources to select from as they start their legal research projects. These include the Witkin California treatises, California Jurisprudence (Cal Jur), Rutter Group California legal practice guides, and Matthew Bender California legal practice guides.
Witkin and Cal Jur are available to Harvard law students electronically through Westlaw and Lexis. Rutter Group guides are available through Westlaw, and Matthew Bender materials are available through Lexis.
The Witkin treatises are a comprehensive research resource for California law. They are among the most heavily used secondary sources by practicing lawyers in the state. Each treatise is organized like an encyclopedia, and features multi-paragraph explanations of legal principles grouped by subject.
Harvard Law students can access Witkin treatises electronically through Lexis and Westlaw. This section discusses how to access and use them in Westlaw.
To access Witkin treatises in WestlawNext, type Witkin in the search box on the home screen and select from the drop-down menu.
The most frequently-used of the Witkin treatises is the Witkin Summary of California Law. It provides general information on most California law topics.
Materials in Witkin treatises are heavily annotated, and these annotations are hyperlinked in Westlaw. Sources cited include California primary law (cases and statutes) and California and U.S. secondary sources (Rutter Group Practice Guides and other practice-oriented materials, ALR, legal encyclopedias, law review articles, restatements, jury instructions, etc.).
California Jurisprudence (Cal Jur) is a multi-volume legal encyclopedia focusing on California law. It is currently in its third edition (Cal Jur 3d). Harvard Law affiliates can access Cal Jur electronically through Westlaw and Lexis.
In the search box on the WestlawNext home screen, start to type California Jurisprudence, then select it from the drop-down menu that appears.
The Cal Jur table of contents will be displayed. From there, you can browse articles by subject, or search.
Cal Jur articles are great for learning about the law and finding relevant primary and other secondary sources. A Cal Jur article provides a short annotated summary of the law. In the Westlaw version of Cal Jur, articles include key numbers; click them to create custom digests of California state and federal cases. Footnotes include citations to relevant American Law Reports annotations and California case law.
For references to related research materials, including primary authority, ALR annotations, legal encyclopedias, and model codes and restatements, click the References link at the top of the article.
An example of a Cal Jur article in Westlaw is shown below.
Practicing lawyers in California rely on the Rutter Group California Practice Guides. They are written by and for practicing attorneys, and offer short explanations of California legal principles. Many Rutter Group guides include include sample legal forms.
Civil Procedure Before Trial (shown in its print format at right) is a popular resource for litigation attorneys who appear in California courts. It covers pre-trial procedural issues, including jurisdiction, discovery, and filing motions.
The Harvard Law Library has a few of the Rutter Group California Practice Guides in print. However, Harvard Law students can best access them through Westlaw.
To access them, type Rutter in the search box on the Westlaw home page. Then click Rutter Group Practice Guides & Other Publications in the drop-down menu that is displayed.
Westlaw will display a list of available Rutter Group guides (shown below), under the heading Secondary Sources > Rutter Group. You can browse them, search them individually, or search them as a group from this screen.
Each Rutter Group guide is written in an outline format. The guide provides practical guidance, as well as citations to statutes and case law that are useful for drafting motions and crafting arguments in practice.
A popular California secondary source on Lexis are the Matthew Bender practice guides. These are similar to Rutter Group guides.
Access in Lexis as follows:
One of the Matthew Bender publications that is especially popular is California Points and Authorities, which "provide for the attorney the applicable decisions and citations required for motions and procedures at the trial level, and, in so doing, to supply the basic material for the preparation of appellate briefs."
Nolo is a legal publisher that specializes in plain-English legal publications for non-lawyers. If you are not a lawyer and wish to educate yourself about California law, an excellent resource is Nolo Guides: California Editions. This collection covers topics as diverse as landlord-tenant law, business entity formation, estate planning, and more.
If you need a lawyer, the Nolo website has a lawyer directory (https://www.nolo.com/lawyers), organized by subject.
Nolo also has a large library of free articles about the law available through its website. Visit https://www.nolo.com/legal-encyclopedia to browse them.

In California, new statutes are either created by state government through the legislative process, or by the state's citizens through the initiative process.
Lawmaking by the Legislature
The legislative branch of California's government creates new law as follows:
Lawmaking by the Voters
Voter lawmaking in California takes place through the passage of ballot measures. There are two type of ballot measures: the referendum and the initiative.
California voters have the right to try to have enacted statutes amended or rejected through the state's voter referendum process. Certain requirements must be met, such as getting enough voter signatures to have a referendum placed on the ballot.
California voters can also create law through California's ballot initiative process. This process allows the legislature and individual citizens to create perspective laws and put them on the ballot. These initiatives are also called propositions because they are proposed to the voters.
Several California ballot initiatives are well-known. Proposition 13, which passed in 1978, affected how property values are calculated when assessing property tax payments. The California Board of Equalization discusses the history and effect of Proposition 13 in its California Property Tax Overview.
In 2008, California voters approved Proposition 8, which amended the California Constitution to state that marriage is only lawful between a man and a woman. The passage of this proposition has been extensively litigated since then. For more information about Proposition 8, see the California Judiciary's Proposition 8 information page.
California Ballot Measures Database
The UC Hastings College of Law Library in San Francisco has a searchable database of California ballot initiatives - coverage is from 1911. It is available at http://library.uchastings.edu/research/ballots/index.php.

An excellent (and free) resources for researching California bills and enacted statutes is the California Legislature's legislative information website, LEGINFO.
This site currently has two versions of its bill information database.
This site has more expansive date coverage than the new version: the 1993/94 legislative session to the present. Information provided includes status, history, bill text, analyses, and voting tallies.
Coverage is from the 1999/2000 legislative session to the present. This site features more advanced searching options, and displays the information as an interactive screen with tabs, making it much easier to navigate.
The entire body of California statutory law is divided by topic into 29 sections, each of which is called a code.
Access to these codes is available for free through LEGINFO's Codes Page; however, the codes on this site are not updated as frequently as the codes offered through commercial databases like Lexis or Westlaw.
California statutory materials in Westlaw and Lexis include annotated versions of the California codes.
This means that, in those subscription databases, each code section includes the statutory language, historical information about enactment and amendments, and references to primary and secondary sources that discuss and explain the legal interpretation of the statutory language. Citators are also available (Keycite in Westlaw and Shepards in Lexis), which allow the researcher to view cases and secondary sources that cited a statute.
Because of these features, subscription databases are much more helpful for in-depth California statutory research than the free online database.
On Westlaw's California Statutes & Court Rules page, you can browse to a code or search all of the statutes in force. If you have a citation to a particular statute, use the California Statutes Find Template (first link under the Tools & Resources menu on the right side of the screen) to navigate directly to it.
In Lexis, California statutes are in "Deering's California Codes Annotated." Browse to Lexis Advance's entire collection of California statutory materials as follows:
HeinOnline has a large collection of digitized historical California statutory materials, dating from the 1850s. It can be an excellent source for historical statutory research.
To view the collection, select State Statutes: A Historical Archive from the HeinOnline Libraries list, and then click the plus-sign next to California.
The Hathi Trust Digital Library has recently digitized historical California Legislative Publications. The collection includes the following:
The HLS library has superseded volumes of West's Annotated California Codes in microfiche.
It is beyond the scope of this guide to provide extensive instructions for researching California legislative history. This process can be time- and labor-intensive, as well as frustrating, especially for older statutes.
Below are links to California legislative history research guides. It is recommended that you review one (or more) of them before starting your research.
If you are affiliated with Harvard Law and need help with a California legislative history research project, please contact the Law Library's Research Services Department.
The UCLA Law Library has an excellent California Administrative Law Research Guide. For comprehensive information about researching California regulations and administrative agency decisions, please refer to that resource.
The California state government's Office of Administrative Law (OAL) website include information about the rulemaking process, as well as the California Code of Regulations (CCR) and the California Regulatory Notice Register.
California has a three-tiered state court system:
California case law research often focuses on appellate cases. These are reported in West's Pacific Reporter, as well as the following state reporters:
California Court of Appeal and Supreme Court opinions are available to Harvard law students through subscription legal databases (Lexis and Westlaw).
In addition, the California judiciary has a free online database of these opinions, http://www.courts.ca.gov/opinions.htm. Note there is no option to Shepardize cases through this database.
Many California Court of Appeal cases, for various reasons, cannot be cited. This includes cases that were never certified for publication, and those that have been "de-published" because the state's Supreme Court has agreed to hear them on appeal.
In the subscription databases, these cases will be marked by a red stop sign (Lexis - see example below) or a red flag (Westlaw).
Although unpublished and de-published cases are not to be cited, they can still be useful for research because they provide citations to primary and secondary sources related to particular legal issues.
HeinOnline's library of historical state case law reporters includes a number of sources for California case law. To access it from the HeinOnline homepage, click State Reports: A Historical Archive > State Reports. Then click California in the map.
Through its Caselaw Access Project (CAP), the Harvard Law School Library Innovation Lab (LIL) has digitized all U.S. federal and state case law published through 2018 -- roughly 40 million pages of court decisions. CAP includes the text of more than 140,000 California state court opinions.
This collection was launched publicly in October 2018 and is available online through https://case.law/. The data is accessible through an open-source API and as bulk-data downloads.
For more information about CAP, email firstname.lastname@example.org.
Note that, in addition to the sources listed below, the court's website may also provide access to documents and other materials related to cases heard in that court.
Westlaw has libraries of California trial court orders, trial court documents, and appellate briefs. Links to these libraries are accessible on Westlaw's California page - on the Westlaw homepage, click State Materials, then click California.
BloombergLaw also has a collection of dockets and litigation materials for California courts. On the BloombergLaw homepage, click the Litigation & Dockets tab, then click Search Dockets. On the Dockets search page, click the Browse button next to Courts, and then select the option for California courts under the State Courts menu. Then click Hide. This will allow you to search California dockets only (shown below).
The law library subscribes to the LLMC database, which also includes an extensive collection of (primarily older) California Supreme Court records and briefs. These are in searchable PDF format. From the LLMC home page, click the green Go button in the Browse Collections box in the middle of the screen. Navigate to the records and briefs collection as follows:
