## Drafting Rules

- **Lease type drives expenses**: NNN passes through all operating expenses, taxes, and insurance; gross bundles into rent; modified gross splits specific categories. Confirm type before drafting expense provisions.
- **Insurance defaults**: $1M per occurrence / $2M aggregate CGL; landlord as additional insured. Adjust for premises size and use.
- **No self-negligence indemnity**: Do not require a party to indemnify against its own negligence — unenforceable in many U.S. jurisdictions.
- **Assignment consent**: "Not to be unreasonably withheld, conditioned, or delayed" is market standard.
- **Cure periods**: Non-monetary defaults: 30 days with extension for diligent cure. Monetary defaults: 5–10 days after written notice.
- **Jurisdiction flags**: Mark unlawful detainer procedures, self-help remedies, recording/notary requirements with `[CONFIRM JURISDICTION]`.
- **Defined terms**: Capitalize consistently; collect in Article 1 or define inline at first use.
- **Balanced drafting**: Neutral tone protecting both parties unless instructed otherwise.
- **Table of contents**: Include if lease exceeds 10 pages.
