AI-Assisted Drafting for US and UK Commercial Agreements
The Drafter's Dilemma
Legal drafting is one of the most time-consuming tasks in legal practice. A well-drafted agreement protects your client; a poorly drafted one creates disputes that cost millions. The challenge is that good drafting requires both creativity (framing clauses for your client's specific situation) and consistency (ensuring defined terms are used uniformly, cross-references are accurate, and no boilerplate is missing).
AI is remarkably good at the consistency part and surprisingly useful for the creativity part — as long as you treat it as a first-draft tool, never a final-draft tool. This chapter shows you how to use AI for legal drafting in US and UK commercial practice, from master agreements to board resolutions to demand letters.
Template-Based vs Free-Form Drafting
Legal drafting with AI works in two modes:
Template-Based Drafting
You provide AI with a template or precedent, and it fills in the specifics. This works well for standardized documents:
Prompt: "Draft a mutual NDA between [Company A], a Delaware
corporation, and [Company B], a company incorporated in
England and Wales. Include:
- 2-year confidentiality period
- Carve-outs for publicly available information, independent
development, and compelled disclosure
- Governing law: New York
- Dispute resolution: binding arbitration under ICC Rules
- Return or destruction of confidential information upon
termination"AI will generate a complete first draft in under a minute. The attorney's job is to review it for completeness, accuracy, and alignment with the client's position.
Free-Form Drafting
You describe the deal terms in plain language and AI structures them into contract language. This requires more careful review but is valuable when no template exists:
Prompt: "We are licensing our proprietary software to a UK
financial services company. Key deal terms:
- Perpetual license, non-transferable, non-exclusive
- Upfront fee of $500,000 + annual maintenance at 18%
- Source code escrow with Iron Mountain
- SLA: 99.9% uptime, 4-hour P1 response time
- Limitation of liability capped at fees paid in preceding
12 months
- Governing law: England and Wales
- Jurisdiction: English courts (exclusive)
Draft the operative clauses (not recitals or definitions)."Defined Terms and Interpretation Clauses
One of AI's strongest capabilities in legal drafting is consistency with defined terms. A well-drafted contract uses defined terms precisely — "Confidential Information" always means the same thing, "Intellectual Property Rights" is never used interchangeably with "IP."
AI can audit a draft for defined term consistency:
Prompt: "Review the following agreement for defined term
issues:
1. Are all defined terms used consistently throughout?
2. Are there any terms used but never defined?
3. Are there any defined terms that are never used?
4. Are cross-references accurate (e.g., does 'Section 8.2'
actually contain what other clauses say it contains)?
5. Flag any instances where a defined term is used with a
slightly different meaning than its definition."US vs UK Interpretation Conventions
AI must account for jurisdictional differences in how contracts are interpreted:
| Convention | US Approach | UK Approach |
|---|---|---|
| Parol evidence | Strong parol evidence rule — prior negotiations generally excluded | More flexible; *Investors Compensation Scheme v West Bromwich* [1998] allows reference to background |
| Contra proferentem | Ambiguity construed against drafter | Applied but less strictly in negotiated commercial contracts |
| Entire agreement | Generally enforceable; excludes prior representations | Enforceable but does not exclude liability for fraud (*Axa Sun Life v Campbell Martin* [2011]) |
| Good faith | Implied in some states (e.g., California); not implied in Delaware | Not a general implied term in English law (*Yam Seng v International Trade Corp* [2013] is limited) |
| Best efforts vs reasonable endeavours | "Best efforts" = most stringent; "commercially reasonable efforts" = common alternative | "Reasonable endeavours" < "all reasonable endeavours" < "best endeavours" — a graduated scale |
Essential Boilerplate Clauses
Every commercial agreement includes boilerplate — the "back end" clauses that attorneys sometimes treat as standard but which can have significant commercial impact. AI can draft these efficiently, but the attorney must verify that each clause serves the client's interests.
Limitation of Liability
Prompt: "Draft a limitation of liability clause for a B2B
SaaS agreement where:
- Direct damages capped at fees paid in the preceding 12
months
- Mutual exclusion of consequential, indirect, incidental,
and punitive damages
- Carve-outs from the cap: indemnification obligations,
breach of confidentiality, IP infringement, willful
misconduct
- Include a 'super cap' of 2x annual fees for carve-out
claims
- Must be enforceable under both New York law and English
law (UCTA reasonableness test)"Key considerations the attorney must verify:
Indemnification
US and UK approaches to indemnification differ significantly:
US approach: Indemnification clauses are common and heavily negotiated. They typically cover IP infringement, third-party claims arising from breach, data breaches, and violation of law. The indemnifying party assumes defense and control of the claim.
UK approach: Indemnification is less common in English law contracts because the common law already provides remedies for breach. When used, indemnities serve a specific purpose — typically to provide recovery for losses that might not be recoverable as damages (e.g., third-party claims, tax liabilities). The key question is whether the indemnity is "on a pound-for-pound basis" or requires proof of loss.
Prompt: "Draft mutual indemnification provisions for a
technology services agreement. Include:
- IP infringement indemnification (mutual)
- Data breach indemnification (by processor to controller)
- Third-party bodily injury / property damage (by service
provider)
- Indemnification procedure: notice, defense, cooperation,
settlement rights
- Exclusions: claims arising from indemnified party's own
negligence, modifications, or use outside scope
- Subject to the overall liability cap in Section [X]"Governing Law and Dispute Resolution
The governing law clause determines which jurisdiction's laws apply to contract interpretation. The dispute resolution clause determines where and how disputes are resolved.
Common combinations in international commercial agreements:
| Governing Law | Dispute Resolution | Typical Use |
|---|---|---|
| New York | NY state/federal courts (exclusive) | US domestic commercial |
| Delaware | Delaware Court of Chancery | Corporate, M&A, PE/VC |
| England and Wales | English courts (exclusive) or LCIA arbitration | UK/international commercial |
| New York or English | ICC arbitration (Paris/London/New York seat) | Cross-border commercial |
| Singapore | SIAC arbitration | Asia-Pacific commercial |
AI can draft appropriate clauses for each combination, but the attorney must consider enforcement — a US court judgment is not automatically enforceable in the UK (no bilateral treaty), while arbitral awards are enforceable in 170+ countries under the New York Convention.
Force Majeure
Post-COVID, force majeure clauses receive far more negotiation attention. AI can draft clauses that account for lessons learned:
Prompt: "Draft a force majeure clause that:
- Lists specific events (natural disaster, pandemic,
government action, war, terrorism, cyberattack, supply
chain disruption)
- Requires notice within [X] business days
- Provides for suspension of obligations (not termination)
during the force majeure period
- Grants termination right if force majeure continues beyond
[90] days
- Excludes payment obligations from force majeure relief
- Addresses the allocation of costs during suspension
- Must be enforceable under both US and English law"Under English law, force majeure is a purely contractual concept — there is no implied force majeure doctrine. Under US law, the related doctrines of impossibility, impracticability (UCC Section 2-615), and frustration of purpose may apply even without a force majeure clause, but their scope is narrow.
Quality Control Workflow
AI-generated drafts require systematic review:
| Step | Task | Time |
|---|---|---|
| 1. Generate first draft | AI (Claude / Spellbook / Harvey) | 5-10 min |
| 2. Defined term audit | AI cross-check | 5 min |
| 3. Substantive review | Attorney | 30-60 min |
| 4. Jurisdictional compliance check | Attorney + AI | 15 min |
| 5. Cross-reference verification | AI | 5 min |
| 6. Formatting and numbering | AI + Word styles | 5 min |
Total: 1-1.5 hours for a first draft that would take 3-5 hours manually. The time savings compound across multiple drafts and redlines.
