A fast checklist of what most often goes wrong when you take over someone else’s commercial lease — grouped by consent, liability, and condition.

General information, not legal advice.
Overview
Most of the risk in assuming a lease clusters in the consent process, the liability you take on, and the condition and status of what you inherit. This checklist links the deeper guides so you can spot the issues before you close.
It is written for the incoming tenant, assignee, or buyer.
Topics to check
A landlord consent standard of "sole and absolute discretion"; a landlord recapture or termination-on-transfer right; consent conditioned on a higher deposit or a personal guaranty; and a sublease with no landlord recognition/non-disturbance agreement (so a master-lease default can end your sublease).
These decide whether the deal can close and how exposed you are — resolve them as closing conditions.
Assignment (Cornell LII Wex)An assumption that reaches pre-closing obligations and existing defaults; no novation or release (for a seller) or no seller indemnity (for a buyer); a missing or stale estoppel certificate; a deposit the landlord does not actually hold; and a subordinate lease with no SNDA where the property carries debt.
Verify status through the estoppel and lock down who owes what before you take over.
Estoppel (Cornell LII Wex)A short remaining term or options that do not survive the assignment; uncapped CAM with a year-end true-up that reaches pre-closing months; a use clause that does not permit your business; deferred maintenance and an inherited restoration ("make-good") obligation; and co-tenancy or continuous-operation terms that limit you.
Price what you are inheriting and confirm you can actually operate before committing.
Key takeaways
- Consent: sole-discretion standard, recapture right, new deposit/guaranty demand, no SNDA on a sublease.
- Liability: assumption of pre-closing defaults, no novation/release, no seller indemnity, missing estoppel.
- Economics: short term, non-transferring options, uncapped CAM true-up, unusable use clause, make-good.
- Verify status through an estoppel and make consent + clean estoppel closing conditions.
- Price the inherited obligations and confirm you can operate before you close.

Frequently asked questions
What is the biggest red flag when assuming a lease?
A combination of broad assumed liability (including pre-closing defaults) with no estoppel certificate to verify status — you can inherit unpaid charges and an existing default without knowing it. Always get a clean, current estoppel and limit your assumption to post-closing obligations.
How do I use this checklist?
Review the deal once for consent and structure, once for liability and verification, and once for economics and condition. Flag anything on this list, and turn the key items — landlord consent, a clean estoppel, deposit transfer, and a release/indemnity — into conditions to closing.
When do I have the most leverage?
Before closing and before the landlord grants consent. Once you take over, you own the inherited obligations, so resolve defaults, secure a release or indemnity, confirm options transfer, and lock down the landlord consent and estoppel first.
