Before you connect

Questions about Legal Reasoning Prover.

The practical details behind the request, access and result.

Can Legal Reasoning Prover help me avoid fake case citations?

Yes. It identifies fabricated case names and weasel authority, ensuring that every citation your AI client provides is a real, verifiable Bluebook entry.

How does Legal Reasoning Prover ensure my legal analysis is logically sound?

It enforces a strict IRAC structure. This means your agent must show the logical bridge between a legal rule and the specific facts of your case before reaching a conclusion.

Does Legal Reasoning Prover work for state and federal law?

It covers both. It forces your agent to identify specific federal circuits, state statutes, and choice-of-law bases rather than giving generic answers.

Can I use Legal Reasoning Prover to check for ABA compliance?

Yes. It specifically requires the agent to disclose adverse controlling authority, which is a core requirement of ABA Model Rule 3.3(a)(2).

What does Legal Reasoning Prover do about jurisdiction issues?

It eliminates jurisdiction blindness. Your AI client will be forced to name the specific court and governing law for every analysis it performs.

Will Legal Reasoning Prover help me draft specific motions?

It does by requiring a specific procedural remedy. Instead of general advice, it forces the agent to identify the specific motion type and statutory basis needed.

Does it verify if cited cases actually exist?

It catches the most common hallucination patterns. placeholder names like 'Smith v. Jones' and 'Doe v. Roe', weasel authority language like 'courts have generally held', and citations that lack proper Bluebook format. It cannot access legal databases to verify every case, but it forces the agent to provide full citation details (party names, reporter, court, year, specific holding). which dramatically reduces fabrication because the agent must commit to verifiable specifics.

Is it only for litigation or does it work for transactional law?

The IRAC framework is most natural for litigation analysis, but the five pivots apply broadly. For transactional work: the 'syllogism' becomes 'does the contract structure achieve the stated objective?', 'authority' becomes 'is the statutory basis for this structure valid?', 'jurisdiction' becomes 'which state law governs this agreement?', and 'remedy' becomes 'what happens if the counterparty breaches?' The reasoning validation is universal. the domain language adapts.

Does it generate legal advice?

No. Legal Reasoning Prover generates zero content. It validates the STRUCTURE of legal reasoning. whether the argument follows IRAC, whether citations are properly formed, whether jurisdiction is identified, whether counter-arguments are addressed. The agent does the legal analysis; the capability proves whether that analysis is structurally sound. It is a reasoning quality gate, not a legal advisor.
