A memorandum sentence describes a statute, a witness's testimony, and a court's legal conclusion. One citation appears at its end. The reader cannot tell which source supports which assertion. The problem begins before punctuation: the sentence contains three different kinds of claims.

Classify primary and secondary sources; distinguish a source's legal character from its delivery method; choose among a citation sentence, a citation clause, and an embedded reference; and place support close enough to identify the assertion it supports. Recognize the limits of this practitioner handbook when preparing academic work.

A judicial opinion, statute, constitution, regulation, litigation document, treatise, periodical article, and webpage have different identifying information. Cases commonly use reporter volume and first page. Statutes use a code title and section. Testimony uses a transcript and often page/line coordinates. A book needs its author and title, and sometimes volume, edition, editor, and year. An article additionally needs the periodical's identity and publication arrangement.

Primary sources are materials such as enacted law and judicial decisions. Secondary sources explain, analyze, or collect law. A secondary source may be helpful and accurate without itself creating the legal rule your receiving court must apply. A pleading is a primary record of a party's allegation, but its allegation is not thereby an established fact or a judicial holding. Classification must remain specific enough to prevent that mistake.

Electronic delivery does not change these categories. A scanned court opinion remains an opinion; an official code displayed in HTML remains a code; a law-review PDF remains an article. A webpage about an opinion is a different source from the opinion. Cite the material that actually supplies the proposition. Chapter 15 develops this distinction for online materials.

A citation sentence follows a complete textual sentence. The ordinary sentence makes the assertion; the citation identifies its support. The citation begins with a capitalized signal when a signal is needed and ends with a period. The method works well when one source supports the entire preceding assertion.

For example: The Supreme Court concluded that separate educational facilities are inherently unequal. Brown v. Bd. of Educ., 347 U.S. 483, 495 (1954). This is the same narrow historical proposition checked in Chapter 1. No signal is required because the source directly states the conclusion. The citation's placement makes its job clear.

A citation clause sits inside a sentence immediately after the assertion it supports. Commas separate it from the surrounding prose. Signals in that setting generally begin in lowercase because the citation clause is part of the sentence. Use this form when a sentence compares propositions with different sources or when delaying a citation would create uncertainty.

An embedded citation integrates the source into the sentence's grammar. The Court in Brown v. Board of Education, 347 U.S. 483, 495 (1954), concluded that separate educational facilities are inherently unequal. The case name now functions as prose, so its abbreviations follow the more limited textual-name convention. The reporter and parenthetical still identify the source.

You can also name the case in the sentence and place the remaining citation after it: In Brown v. Board of Education, the Court concluded that separate educational facilities are inherently unequal. 347 U.S. 483, 495 (1954). This form is intelligible because the name and citation are closely connected. Avoid splitting identification so far apart that the reader must search backward to reconstruct a full reference.

Form What the reader sees Editorial consequence
Citation sentence Assertion. Authority. Support normally covers the preceding assertion
Citation clause Assertion, authority, continuation. Support is attached to the specific clause
Embedded reference In Authority, the court reasoned ... The source participates in the sentence's grammar

The distinction affects abbreviation and signal capitalization, but its main purpose is clarity. Choose the placement after deciding what the source proves. Moving a citation cannot make a source support a different assertion.

Fictional training example — not legal authority. A source packet gives a fictional notice statute, the recipient's sworn statement that she never received a letter, and a fictional opinion explaining the legal consequence of inadequate notice. The draft reads: “The law requires mailed notice, Lane never received notice, and the agency therefore lacked authority. Lane Declaration paragraph 4.” The declaration supplies the witness's account. It cannot establish the statute's rule or the opinion's legal consequence.

Repair the paragraph by separating its jobs. First state the notice rule and cite the statute. Then state Lane's account and cite the declaration. Finally explain the legal inference with an opinion citation and any needed signal. If the legal source does not establish lack of authority under these facts, narrow or qualify the conclusion. This repair addresses attribution and reasoning, not simply citation placement.

The packet is fictional, but the checking method transfers to actual practice. For each sentence, identify the claim type: legal rule, factual allegation, established record fact, quotation, interpretation, or inference. Ask what kind of source could establish that particular claim. A citation to a motion may show what counsel argued. It cannot automatically show that the argument was accepted.

This handbook uses practitioner conventions for memoranda, briefs, and comparable documents. Academic legal writing often uses extensive footnotes and additional typography and cross-reference conventions. Moving a citation into a footnote does not by itself transform a practitioner citation into a complete law-review citation. Check the instructor's directions or publication's style requirements.

Footnotes may be useful in practitioner documents too. Their availability depends on the receiving document's rules and purpose. Indigo accommodates practitioner citations in text and footnotes; it does not make either arrangement universally mandatory. Choose a consistent approach that preserves the connection between claim and support, and verify any court-specific restrictions. The brief academic comparison in the reference section is an orientation, not a full scholarly manual.

Do not label every Internet source a website. Inspect what the electronic file actually contains. Do not attach a single citation to a sentence containing unrelated legal and factual assertions unless it genuinely supports them all. Do not use a case name with extensive citation abbreviations in readable prose without checking the textual-name rule. Do not capitalize See in the middle of a citation clause merely because it begins a citation.

When a source supports only part of a sentence, move its citation to that part or split the sentence. When a citation becomes so long that it obscures the argument, first examine whether every source and every clause is necessary. Typography cannot repair a sentence trying to make too many distinct assertions at once.

Identify the source type, then the claim type. Place the citation after the assertion it supports. Use a citation sentence for a complete preceding assertion, a citation clause for a portion of a sentence, and an embedded reference when naming the authority advances the prose. Preserve the distinction between a rule, an allegation, evidence, and an inference. Check the receiving document's directions before adopting a footnote system.

Fictional training example — not legal authority. A supplied packet contains three items. Harbor Code § 8(a) requires a written request. Vale Declaration ¶ 3 states that Vale submitted a request on April 1. A fictional court's order says that whether the request satisfied § 8(a) remains disputed. The draft sentence reads: “Vale complied with the written-request law on April 1, and the court accepted that compliance. Vale Decl. ¶ 3.” Every fact and provision in this paragraph belongs only to the training packet.

Begin by listing the sentence's assertions. It asserts a legal requirement, an act by Vale, legal compliance, and judicial acceptance. The declaration supports the witness's statement about submitting a request. The code establishes the written-request requirement. The order expressly leaves compliance disputed. None of these sources supports the draft's account of judicial acceptance. The citation problem is therefore partly a sentence problem: one compressed sentence has merged a rule, testimony, an inference, and a false description of a ruling.

A useful repair reads: “Harbor Code § 8(a) requires a written request. Vale states that she submitted a request on April 1. Vale Decl. ¶ 3. The court's order leaves compliance with § 8(a) disputed.” The order's supplied citation information must accompany the last sentence in a completed document. This workshop gives its content but not its full identifying metadata, so it does not pretend to construct an actual full order citation. The omission is deliberate teaching restraint: knowing what a source says is not permission to invent its docket number or date.

Notice that the repair uses different verbs. Requires describes enacted text. States identifies testimony. Leaves disputed describes the order. Those verbs tell the reader how the sources relate to the assertions. The draft's complied and accepted asserted conclusions the packet does not establish. Replacing them is a substantive correction, not a matter of choosing a more elegant signal. A see signal cannot make the court accept something its order expressly leaves unresolved.

Placement becomes easier after this separation. The code citation can attach directly to the legal requirement. The declaration follows the witness's statement. The order follows its own procedural description. If the paragraph later argues that Vale's evidence should satisfy the statute, that argument needs its own reasoning and any relevant legal authority. It should be presented as the writer's argument, not smuggled into a sentence describing the record.

The same method helps when a source is discovered inside another source. A treatise may quote a statute and discuss an opinion. Determine whether your sentence describes the treatise's analysis, the statute's command, or the opinion's holding. If you rely on the underlying law, inspect it when available. If you have inspected only the treatise, describe that limitation accurately and use the applicable indirect-source convention rather than implying firsthand review.

For your own drafting, underline each assertion in a crowded sentence and write its source type in the margin. Two incompatible source types usually suggest a sentence break or a citation clause. A missing source type suggests a research task. A contradiction suggests a revision to the assertion itself. The exercise is especially valuable before a citation manager inserts perfectly formatted references into prose that still confuses allegations with findings.

An ordinary citation sentence at a paragraph's end does not automatically certify every preceding sentence. Readers need to know whether it supports the last assertion, several connected assertions, or only a quoted phrase. When the paragraph changes from a legal rule to a disputed factual account, a fresh citation or an explicit attribution usually makes the transition clearer. Repeating a short source reference can be more helpful than asking one distant full citation to carry four different propositions.

Fictional training example — not legal authority. A packet supplies Harbor Code § 8(a), which requires a written request; Vale Declaration ¶ 3, which states that a request was mailed; and the same declaration's paragraph 4, which states that no response arrived. The sentence “The code requires writing, and Vale received no response. Vale Decl. ¶ 4” assigns two jobs to one source. A clear repair is: “Harbor Code § 8(a) requires a written request. Vale states that she received no response. Vale Decl. ¶ 4.” If the next sentence discusses mailing, paragraph 3 supplies its factual attribution. Neither declaration paragraph establishes whether mailing legally satisfied the code.

Avoid a different trap when revising citation placement: deleting an attribution because the source now appears nearby. “The witness testified that the light was red” reports testimony. “The light was red” asserts the underlying event. Moving the transcript citation between those sentences changes neither their different meanings nor the evidence needed to support them. Preserve the distinction deliberately.

Suppose a commentary accurately describes a case you have not read. If the sentence reports the commentary's interpretation, cite the commentary and identify the interpreter. If the sentence instead asserts what the court held, open the opinion and verify the passage before claiming a direct check. A quotation copied from the commentary may carry its author's omission, added emphasis, or transcription error. Those features require comparison before you attribute the exact words to the court.

An indirect quotation can be presented honestly when the original remains unavailable: identify the source actually consulted and use an appropriate quoting or citing parenthetical to disclose its relationship to the underlying material. Do not create a fictitious direct pinpoint for the inaccessible source. The distinction is about the evidence for your attribution. A source inside a citation is not necessarily a source you inspected.
