Contract Drafting

Disclaimer: This skill provides general guidance on commercial contract structure and drafting best practices. It is NOT legal advice. Always have qualified legal counsel review contracts before signing or sending them to counterparties.

Commercial contracts are the binding agreements that govern business relationships. Good contracts prevent disputes by making expectations, obligations, and risk allocation explicit. This skill covers the structure, key clauses, and drafting process for the most common commercial agreements - NDAs, MSAs, SaaS subscriptions, licensing agreements, and data processing addendums - and the process of reviewing and redlining contracts received from counterparties.

When to use this skill

Trigger this skill when the user:

• Needs to draft a Non-Disclosure Agreement (NDA) or Confidentiality Agreement
• Wants to create a Master Services Agreement (MSA) or Statement of Work (SOW)
• Is drafting SaaS subscription terms or an End User License Agreement (EULA)
• Needs to review, annotate, or redline a contract received from another party
• Is creating a software or content licensing agreement
• Needs a Data Processing Agreement (DPA) for GDPR or other privacy compliance
• Wants to understand a specific contract clause or term
• Is managing contract renewals, amendments, or terminations

Do NOT trigger this skill for:

• Tax, employment law, or regulatory compliance advice - those require specialist counsel
• Litigation strategy or dispute resolution proceedings in progress

Key principles

1. Clarity over legalese - Plain language reduces disputes. Every obligation, right, and restriction should be understandable on first reading. If a clause requires a lawyer to decode, rewrite it. Legalese that obscures meaning creates ambiguity that parties exploit in disputes.
2. Define all terms - Every capitalized term must appear in a Definitions section or be defined on first use. Undefined terms invite competing interpretations. "Confidential Information," "Intellectual Property," "Affiliate," and "Services" are the most commonly contested undefined terms.
3. Risk allocation must be explicit - Contracts exist to allocate risk. Who bears the cost of a data breach? Who indemnifies whom for IP infringement claims? What is the liability cap? If risk allocation is implicit or absent, courts default to interpretations that may not match what either party intended.
4. Standard terms reduce negotiation - Using market-standard positions (e.g., mutual NDA, uncapped IP indemnity, 12-month liability cap for SaaS) speeds up deals. Know which clauses are standard so you can focus negotiation energy on the genuinely non-standard asks.
5. Version control everything - Every draft should be dated and versioned. Track changes between drafts. Maintain a redline history. In a dispute, the negotiation history can be used to interpret ambiguous terms (the "course of dealing" doctrine).

Core concepts

Contract structure

Every commercial contract shares a common skeleton:

• Preamble - Parties, date, and recitals (background/context)
• Definitions - Capitalized terms and their meanings
• Operative clauses - The actual obligations and rights (services, payment, license grant)
• Representations and warranties - Statements of fact each party makes
• Indemnification - Who covers costs if a third party makes a claim
• Limitation of liability - Caps on damages each party can recover
• Confidentiality - What stays private and for how long
• Term and termination - Duration, renewal, and grounds to exit early
• General provisions (boilerplate) - Governing law, dispute resolution, notices, assignment, entire agreement, severability, force majeure

Key clauses

Indemnification - Party A agrees to defend and pay costs if Party B is sued by a third party because of Party A's breach or IP. Usually mutual for IP, one-sided for gross negligence.

Limitation of liability - Caps total recovery at a multiple of fees paid (12 months is standard for SaaS). Always carve out: death/personal injury, willful misconduct, confidentiality breaches, and IP indemnity from the cap.

Representations and warranties - "We represent that our software does not infringe third-party IP." Breach of a warranty triggers indemnification or termination rights.

Governing law and jurisdiction - Which state/country's law applies and where disputes are resolved. Avoid agreeing to the other party's home jurisdiction.

Assignment - Whether either party can transfer the contract to a third party (e.g., in a merger or acquisition). Standard position: neither party may assign without consent, except to an acquirer of all or substantially all assets.

Risk allocation

Amendment process

All changes to a signed contract must be in writing, signed by both parties, and reference the original agreement. Verbal amendments are unenforceable in most jurisdictions. Use a formal Amendment or Change Order template with a sequential number (Amendment No. 1, Amendment No. 2) to maintain a clear audit trail.

Common tasks

Draft a mutual NDA

A mutual NDA protects confidential information exchanged in both directions. Key sections and what belongs in each:

1. Definition of Confidential Information
   - Broad enough to cover all sensitive info
   - Exclude: public domain, independently developed, received from third party,
     required to be disclosed by law (with notice obligation)

2. Obligations of receiving party
   - Use only for the Permitted Purpose
   - Protect with at least the same care as own confidential info (not less than
     reasonable care)
   - Share only with employees/contractors on need-to-know basis
   - Ensure recipients are bound by equivalent obligations

3. Term
   - Duration of disclosure period (e.g., 2 years)
   - Survival of confidentiality obligations (typically 3-5 years after expiry)

4. Return / destruction
   - Upon request or expiry, return or certify destruction of materials

5. Remedies
   - Acknowledge that breach causes irreparable harm - injunctive relief available
     without bond requirement

Mutual NDA checklist:

• Both parties named as both Disclosing Party and Receiving Party
• "Confidential Information" defined broadly but with standard exclusions
• Permitted Purpose scoped narrowly (e.g., "evaluating a potential business relationship")
• Residuals clause reviewed - common vendor ask, weakens protection significantly
• Governing law and jurisdiction specified
• Dispute resolution (arbitration vs. litigation) agreed

Draft an MSA - key sections

A Master Services Agreement governs the overall relationship; Statements of Work (SOWs) or Order Forms attach to it for specific engagements.

MSA core sections:

1. Services - reference to SOWs; change order process
2. Fees and payment - invoicing cadence, payment terms (Net 30 is standard), late fees
3. Intellectual property ownership - who owns work product (customer vs. vendor)
4. License grant - what license vendor grants to deliverables if customer doesn't own
5. Confidentiality - reciprocal, typically survives 3 years post-termination
6. Representations and warranties - authority to enter, non-infringement, compliance
7. Indemnification - IP indemnity (vendor), misuse indemnity (customer), mutual for breach
8. Limitation of liability - 12-month fee cap; carve-outs listed above
9. Term and termination - initial term, auto-renewal, termination for cause (30-day cure), termination for convenience (60-day notice)
10. Governing law - specify state/country

IP ownership decision tree:

• Custom development for customer - customer owns work product
• Vendor's pre-existing IP used in deliverable - vendor retains, grants license
• General improvements to vendor platform - vendor owns (common vendor position)

Draft SaaS subscription terms

SaaS agreements govern access to hosted software. Key distinctions from on-premise licenses: customer never receives software copy; uptime and data portability matter.

Must-have SaaS clauses:

• License grant - Non-exclusive, non-transferable right to access and use the Service during the subscription term
• Acceptable use policy (AUP) - Prohibited uses; consequences of violation
• SLA and uptime - Minimum availability (99.9% is standard); credit remedy for downtime; scheduled maintenance windows
• Data ownership - Customer owns its data; vendor has license to process data to provide the service
• Data portability - Customer can export data in machine-readable format during term and for 30 days after termination
• Data deletion - Vendor deletes customer data within 30-90 days of termination
• Security - Vendor maintains industry-standard security; incident notification within 72 hours (aligns with GDPR)
• Fees and auto-renewal - Subscription fees, renewal pricing, required notice to cancel (typically 30-60 days before renewal date)

Review and redline contracts - checklist

When reviewing a contract received from a counterparty:

Pass 1 - Commercial terms (business review)

• Scope of services/license matches what was agreed in negotiations
• Fees, payment terms, and renewal pricing match the proposal
• Term and termination rights are balanced
• SLA and remedies are acceptable

Pass 2 - Risk clauses (legal review)

• Liability cap is mutual and set at an acceptable level
• Consequential damages exclusion is mutual (not one-sided)
• IP indemnity covers customer's use of the product
• Confidentiality obligations are mutual; no broad residuals clause
• Governing law is acceptable (flag if counterparty's home jurisdiction)
• Assignment restricted - cannot assign to competitors without consent
• No unilateral price increase rights without adequate notice

Redlining etiquette:

• Track all changes - never send a clean document with hidden edits
• Add comments explaining why you are requesting a change, not just what
• Prioritize - distinguish must-haves from nice-to-haves in your cover email
• Offer alternative language when you delete a clause - it signals good faith

Draft licensing agreements - types

Core license grant clause structure:

[Licensor] grants to [Licensee] a [exclusive/non-exclusive], [sublicensable/
non-sublicensable], [perpetual/term], worldwide license to [reproduce, distribute,
display, perform, modify] the [Licensed Materials] solely for [Permitted Purpose].

Every word in the grant clause matters. Omitting "modify" means licensee cannot create derivative works. Omitting "distribute" means they cannot share the output.

Create a DPA for GDPR compliance

A Data Processing Agreement is required under GDPR Article 28 whenever a controller (customer) engages a processor (vendor) to process personal data.

Required DPA elements (GDPR Article 28(3)):

1. Subject matter and duration - What data is processed and for how long
2. Nature and purpose - How and why processing occurs
3. Type of personal data - Categories of data (names, emails, health data, etc.)
4. Categories of data subjects - Employees, customers, end users, etc.)
5. Processor obligations:

- Process only on documented instructions from controller - Ensure personnel are bound by confidentiality - Implement appropriate technical and organizational security measures - Assist controller with data subject rights (access, deletion, portability) - Delete or return all data after services end - Provide all information necessary to demonstrate compliance - Notify controller of any personal data breach without undue delay

1. Sub-processors - List authorized sub-processors; notify controller of changes; flow down equivalent obligations
2. International transfers - Mechanism for transfers outside EEA (SCCs, adequacy)
3. Audit rights - Controller may audit processor's compliance

Manage contract lifecycle

Pre-signature:

• Use a contract template library to avoid starting from scratch
• Run all contracts through legal review above a materiality threshold (e.g., >$25K)
• Maintain a signature authority matrix - who can sign what dollar value
• Store executed contracts in a contract management system with metadata tags

Post-signature:

• Calendar all key dates: renewal deadlines, notice deadlines, price escalations
• Set reminders 90 days before renewal if notice to cancel is required
• Track obligations - who owes what to whom and by when
• Document any material correspondence that constitutes an amendment or waiver

Renewal and renegotiation:

• Benchmark pricing against market before renewing
• Review SLA performance data before accepting auto-renewal
• Consolidate vendors where possible to increase negotiating leverage

Anti-patterns

Gotchas

1. Residuals clauses gut NDA protection - A residuals clause allows the receiving party to use "information retained in the unaided memory of persons who have had access to confidential information." This effectively means any employee who read your confidential material can freely use it later. Always review NDAs for residuals clauses and strike or narrow them aggressively.
2. "Termination for convenience" asymmetry - Many vendor-drafted contracts include termination for convenience for the vendor but not the customer, or require 90-day notice from the customer but allow the vendor to terminate with 30 days. Review termination provisions for symmetry and ensure the notice period is practical for your transition timeline.
3. Auto-renewal with a short cancellation window - A contract that auto-renews annually with a 60-day cancellation notice is effectively a trap for busy teams. The renewal date must be calendared on signature day. A single missed deadline locks you in for another year.
4. "All IP created for customer" in MSAs - A customer-favorable MSA clause claiming ownership of all IP created during the engagement may inadvertently claim ownership of improvements to the vendor's core platform. Always carve out vendor's pre-existing IP and general platform improvements before agreeing to broad work-for-hire language.
5. Governing law ≠ dispute resolution venue - A contract can specify California law governs but require disputes be resolved in New York courts. These are separate clauses. Check both; agreeing to the counterparty's home jurisdiction for litigation is a significant concession.
