Sublease Agreement

Drafting sublease agreements manually requires reviewing the original lease, researching state-specific requirements, and ensuring all essential clauses are properly structured and compliant. Attorneys spend hours cross-referencing templates, verifying landlord consent provisions, and customizing terms for rent, deposits, maintenance, and liability—time that could be spent on higher-value client work.

Frequently asked questions

Q

How does CaseMark ensure the sublease complies with the master lease?

A

CaseMark analyzes your uploaded master lease to identify critical provisions including subletting restrictions, consent requirements, use limitations, and material obligations. The AI automatically incorporates these terms into the sublease agreement and flags any potential conflicts or conditions precedent that must be satisfied. This ensures the sublease remains subordinate to and consistent with the master lease, protecting your client from inadvertent defaults.

Q

Can I customize the sublease agreement for commercial versus residential properties?

A

Yes, CaseMark tailors the sublease agreement based on property type and transaction details you provide. Commercial subleases include provisions for business use restrictions, operating expenses, and commercial insurance requirements, while residential subleases incorporate tenant protection laws, habitability warranties, and consumer-focused disclosures. You can further customize any provision to match your specific transaction requirements.

Q

What happens if the master lease doesn't allow subletting?

A

CaseMark will identify anti-subletting clauses or consent requirements in the master lease and alert you to these restrictions. The generated agreement will include conditional language making the sublease contingent upon obtaining landlord consent, and will provide a landlord consent section for execution. This ensures you're aware of all prerequisites before finalizing the transaction and helps you advise clients on necessary next steps.

Q

Does the sublease agreement include all necessary exhibits and attachments?

A

Yes, CaseMark generates a complete execution-ready package including the master lease as an exhibit, property descriptions or diagrams, personal property inventories if applicable, and landlord consent sections. The document includes a table of contents for longer agreements and properly formatted signature blocks for all parties. All exhibits are clearly referenced in the body of the agreement for easy navigation and completeness.

Q

How does CaseMark handle security deposits and financial terms?

A

CaseMark creates comprehensive financial provisions including rent amounts, payment schedules, late fees that comply with statutory limits, and detailed security deposit terms. The AI incorporates jurisdiction-specific requirements for deposit holding, interest payments, return timelines, and permissible deductions. It also addresses the relationship between sublease rent and master lease rent, ensuring compliance with any rent control or markup restrictions in your jurisdiction.
