契約書をレビューするNot legal advice: This page explains, in plain language, how a legal document typically works. It is general information — not legal advice about your specific situation. If the stakes are meaningful, or a deadline is close, speak with a licensed lawyer before relying on anything you read here.
What a lease actually commits you to
A lease is a contract giving you the right to use property for a specific period, in exchange for rent and compliance with a long list of conditions you usually don't read. Most leases are drafted by the landlord's lawyer for the landlord's benefit — standard forms are rarely neutral.
The meaningful decisions are made in clauses you skim: rent escalation, assignment, default, personal guarantees, restoration on move-out, and renewal mechanics. These clauses rarely bite until something changes — you need to sublet, the business pivots, the market shifts — and by then the lease governs.
Attorly reads both residential and commercial leases, compares the key clauses to market standard for your jurisdiction, and flags deviations that typically cost tenants the most.

Before you sign the lease
Negotiate now. Almost nothing in a lease is non-negotiable.
- 1
Pin down the real rent
Base rent is rarely the full cost. Look for operating expenses, CAM charges, utilities, parking, taxes, insurance, and escalation clauses. Attorly totals the all-in cost and projects it over the lease term.
- 2
Understand the security deposit rules
How much, where it's held, under what conditions it's returned, and how long the landlord has to return it. Jurisdictions vary — Attorly flags clauses that don't comply with local law.
- 3
Check what you're allowed to do with the space
Use restrictions, permitted alterations, subletting, assignment, pets, guests, signage. The lease will define what counts as a "breach" — some clauses you'll violate accidentally on week one.
- 4
Read the default and termination sections
Cure periods, acceleration clauses, and penalty rent. A missed payment during a bad month can trigger the remaining rent for the entire term if the acceleration clause is aggressive.
- 5
Take photos and document the condition before move-in
Walk through with the landlord or a witness, photograph every room, note every defect in writing, and attach it to the lease. This single step eliminates the most common deposit dispute.
