Contract Law

PLA 1003Activity 10

Why it Matters

Contract law decides which promises the state will enforce and which are just talk. That line runs through an ordinary day: a lease, a job offer, a checkout screen, a box you tick to get past a splash page. Learn how an agreement forms and you can say when you have bound yourself, when the other side has, and what the law does when someone walks away. The skill pays whether you practice, work as a paralegal, run a business, or just want to know what you agreed to before you tapped the button. Miss it, and you learn the terms later, when the other side enforces them.

Current Context

In January 2026, a federal judge in the Southern District of Ohio held that Anna’s Archive was bound by WorldCat’s terms of use and entered a default judgment and a permanent injunction against the site (opens in a new tab). Nobody at Anna’s Archive had clicked to accept anything, and the court still found a browsewrap agreement: a sophisticated party scraping the site daily had constructive notice of the terms. Getting there took two years, through a denied motion, two certified questions of Ohio law the state supreme court declined to answer, and OCLC’s renewed motion for default judgment in November 2025 (opens in a new tab). That result cuts against Specht v. Netscape, where terms a user never clearly accepted did not bind him, and it cuts on a different axis. Part 3 asks whether the terms you accepted would hold against you, and the answer may turn on who you are as much as on how the screen was built.

Key Concepts

Contract

An agreement between two or more parties that creates duties a court will enforce. Most promises never reach that status, because the law backs only the ones that meet its requirements. Formation is therefore the first question in any contract dispute, and often the only one that matters.

Offer

A proposal to enter an agreement on stated terms, communicated so the other side can accept and close the deal. It has to be definite enough that a court could say what was promised. An invitation to negotiate is not an offer, and neither is a vague expression of interest.

Acceptance

Agreement to the offer’s terms, given in the way the offer allows. It can come by words, by signature, or by conduct: clicking a button, or performing the act the offer requested. An acceptance that changes the terms generally is not an acceptance at all.

Consideration

Something of value each side gives or promises in exchange for what the other gives or promises. It separates a bargain the law will enforce from a one-sided gift promise, which it will not. What is exchanged can be money, a service, a promise, or a legal right you give up.

Mutual Assent

The parties’ shared agreement to be bound, often called a “meeting of the minds.” Courts measure it objectively, by what a reasonable person would take from the parties’ words and conduct rather than from their private intentions. So a party cannot escape a deal by saying they were secretly joking.

Breach

A failure to perform a contractual duty when performance is due, with no legal excuse. Breach can be total or partial, and a trivial shortfall by a party acting in good faith may not count as one. Find the breach first, because nothing opens the door to a remedy until you do.

Remedy

The relief a court gives the non-breaching party to make up for the breach. Usually that is money damages, measured to put the injured party where performance would have left them. Less often a court orders specific performance, making the breaching party do what it promised.

Clickwrap and Browsewrap

Two ways an online agreement tries to bind a user. A clickwrap demands an affirmative act, checking a box or clicking “I Agree,” before the user can go on. A browsewrap posts the terms somewhere on the site and treats continued use as acceptance, which courts often refuse to enforce because the user never clearly assented.

Resources

Foundational Case Bank

These are the cases most U.S. Contracts courses are built around. Each settled a question about how a contract forms, how it must be performed, or what a court does when someone breaks it. Several are English decisions, because American common law came from England and these opinions still anchor the doctrine here. Read one in full for Part 2; the rest are reference across the unit. Open each through its link, or pull it on Westlaw by name.

Formation

Performance

Remedies

What to Do

You will work from the elements of formation, through a case from the canon, to an agreement you accepted without reading. The skill is issue spotting: running a set of facts against the elements, seeing which one is missing, and saying what follows. Use the AI as a sparring partner that questions your reasoning. It is not an answer key.

Part 1: The Foundations

Build a working map of how a contract forms and what happens when it fails. Read the Cornell LII entries on contract and consideration, then run the Doctrinal Mapper prompt to sort the elements into formation, performance, and remedies. Push the AI on the line between an enforceable bargain and a gift promise, because that is where beginners first slip. By the end you should be able to state what each element requires and why losing any one of them sinks the whole agreement.

Part 2: Brief a Case from the Canon

Now put the map against a real opinion. Pick one case from the Foundational Case Bank and read it in full, on Westlaw or through its link. Choose from a category that interests you, and try not to take the same case as the person next to you, so the class covers the canon between us. Before you look at any summary, brief the case in your own words: the facts, the question the court had to decide, the holding, and the reasoning. Then run the Socratic Examiner prompt and let it question your brief. Bring the Doctrinal Mapper’s output from Part 1 back in, place your case in formation, performance, or remedies, and say how it relates to the cases around it. Read the judge’s actual words closely. The objective theory of assent that decides Lucy v. Zehmer is the same idea that governs the online terms in Part 3.

Part 3: The Agreement You Already Signed

Turn to a contract that already binds you. Pick a social media platform, a streaming service, or an app you use, find its Terms of Service, and locate the moment of formation: the screen or the step where you supposedly accepted. Run the Formation Analyzer prompt to test whether there was a valid offer, an acceptance, and consideration, and whether the terms arrived as a clickwrap or a browsewrap. Measure what you find against Specht v. Netscape. The Second Circuit held there that a user who downloaded free software was not bound by license terms sitting on a screen below the download button. Then answer the question the doctrine lets you answer: would the agreement you accepted actually hold up?

Part 4: Verify Before You Trust

AI tools state contract rules with confidence and cite cases that do not exist. Take two or three specific claims the AI made in Parts 1 through 3: a stated rule, a case name, or a description of a holding. Check each against a primary source, on Cornell LII or on Westlaw through the Daytona State College library. Run the Citation Checker prompt to structure the review, then record which claims held up, which were imprecise, and whether any authority was invented. That habit is what makes a paralegal worth relying on.

Part 5: Summary and Reflection

Write a 400 to 600 word reflection on what you learned. Start with the case you briefed. How did your own reading compare to the AI’s summary, and what did the judge’s words show you about legal reasoning that a summary left out? Then turn to the modern agreement. What surprised you in the terms you have been accepting, and would that agreement satisfy the formation elements you mapped in Part 1? Close by connecting the two. You moved from a case in the canon to a clickwrap you scrolled past. So what do you now think a contract is, and does the freedom to bind yourself feel more meaningful, more complicated, or both?

Include one AI chat link with a 1–2 sentence explanation of what the conversation shows and why you chose to share it.

Suggested AI Prompts

Use these prompts as a starting point, then adjust them to fit your goal. Strong prompting develops through trial, revision, and testing. It’s a foundational skill that grows into more advanced AI work such as context engineering and agent-based workflows.

Doctrinal Mapper

I’m a student in an Introduction to Law survey course beginning the contract law unit. Give me a clear but accurate overview of contract law organized into three phases: Formation, Performance, and Remedies. Under Formation, cover offer, acceptance, consideration, and mutual assent, and name the main defenses that can defeat a contract, such as lack of capacity, duress, or fraud. Under Performance, explain conditions, substantial performance, breach, and anticipatory repudiation. Under Remedies, explain expectation damages, reliance damages, restitution, and specific performance. Use correct legal terms but define each one in plain language the first time you use it. End by explaining, with a simple example, why the law enforces a bargain but not a one-sided gift.

Role assignment plus structured output: naming your audience and fixing a three-part frame keeps the model from wandering. You get the same map every time, not whatever it finds most interesting.

Socratic Examiner

You are a law professor running a Socratic dialogue. I am studying a landmark contract case and will give you the case name and my own brief of it: the facts, the issue, the holding, and the court’s reasoning. Do not give me the answer or your own summary. Instead, ask me one question at a time that tests my reasoning, drawing on the elements of contract law: who the parties were and what each one did, which element of formation, performance, or remedies the case turns on, what rule the court announced, and why the losing side’s argument failed. After each answer I give, point out any gap or error and ask a follow-up. Only after I have worked through the brief should you confirm what I got right and what I missed.

Socratic elicitation: forbid the answer, allow one question at a time, and your own reasoning stays in front. The AI then finds the holes in your brief instead of filling them for you.

Formation Analyzer

Act as a contract analyst. I will paste the Terms of Service for an app or platform I use. Walk through the Formation stage only, in this order. First, identify whether there is a valid offer and quote the specific language that makes it one. Second, identify how acceptance occurs and state whether this is a clickwrap, which requires an affirmative click, or a browsewrap, which treats mere use as acceptance. Third, identify the consideration each side gives. Reference Specht v. Netscape Communications Corp., 306 F.3d 17 (2d Cir. 2002), where the court refused to enforce terms a user never clearly assented to, and tell me whether this agreement looks more or less enforceable than the terms in that case. Pause after the analysis and ask me what questions I have before going further.

Source grounding meets decomposition: a named case anchors the analysis, and ordered sub-questions stop the model from handing back a vague summary. That structure is the seed of a repeatable contract-review workflow.

Citation Checker

I am going to give you several statements about contract law that an AI tool generated, including a case name and a rule. For each statement, tell me how confident you are that it is accurate and flag anything you are uncertain about. Do not confirm a case exists or describe its holding unless you are confident; if you are not sure, say so plainly and tell me to verify it against Cornell LII or Westlaw. List any claim that you think may be wrong, imprecise, or fabricated, and explain why. Treat your job as catching errors, not reassuring me.

Red-teaming turned inward: the model hunts its own errors and states its own uncertainty, which works against its pull toward confident, sometimes invented, authority. The habit you keep is checking every cite against the source.
