Your lease assignment and subletting rights depend first on what your lease says: if it is silent on transfers, you can generally assign or sublet without the landlord’s permission; if it requires consent, the landlord usually cannot withhold that consent unreasonably; and in almost every case, handing the space to someone else does not, by itself, release you from your obligations to the landlord. Common law disfavors restrictions on transferring property interests, so the default rule gives tenants freedom to transfer. The specific language of any transfer clause in your lease narrows that freedom.
Assignment or Sublease: Which One Are You Doing
These two get mixed up constantly, and the difference changes who owes what to whom.
An assignment transfers your entire remaining interest in the lease to a new person for the full remaining term. The assignee steps into your position and deals directly with the landlord. You’re out of the picture day-to-day, though not necessarily for liability.
A sublease is a partial transfer. You hand over a portion of the remaining term or a portion of the space and keep a slice of the lease for yourself, called a reversionary interest. The sublessee pays rent to you, and you continue paying rent to the landlord. The landlord’s only contractual relationship is still with you.
The distinction matters most when something goes wrong. In an assignment, the landlord can pursue the new tenant directly for lease violations because a direct legal relationship exists. In a sublease, if your sublessee damages the unit or stops paying, the landlord comes to you first.
What Your Lease Says Controls
When the Lease Is Silent
If your lease says nothing about assignment or subletting, you can generally do either one freely. Courts treat transfer restrictions as restraints on alienation and read them narrowly. A clause prohibiting assignment does not, by itself, prevent subletting. A clause barring subleases does not stop you from assigning. A landlord who wants to block both must say so in plain terms.
When the Lease Requires Consent
Most modern leases require the landlord’s written consent before any transfer. A growing number of jurisdictions apply the rule that a landlord cannot unreasonably withhold consent, even when the lease does not explicitly include that standard. The reasoning is that you bargained for a usable lease, and blocking a reasonable transfer undermines that bargain.
When the Lease Has a Recapture Clause
Some leases, particularly commercial ones, give the landlord a third option: terminate the lease and take the space back when you ask to transfer it. Submitting a transfer request is what triggers the right. If your lease has a recapture clause, requesting an assignment can cost you the lease entirely, so read the transfer provisions carefully before you start the process.
What Counts as a Reasonable Refusal
When the “not unreasonably withheld” standard applies, the landlord needs a genuine commercial justification to say no. Courts have accepted several:
- Financial weakness: the proposed transferee is insolvent, has a poor payment history, or lacks the income to cover rent.
- Use conflicts: the new occupant plans to use the space in a way that violates the lease or clashes with the property’s character.
- Competitive harm: in commercial settings, the proposed tenant would compete with other businesses in the same building or shopping center.
- Revenue impact: the transfer would undermine a percentage-rent clause or otherwise reduce the landlord’s expected income.
What does not qualify: refusing because the landlord wants to re-rent at a higher rate, or because of a vague personal objection to the new tenant. A useful test is to compare the standards the landlord applied to you when you signed. If the landlord is now imposing materially higher standards on your proposed transferee, the objection looks less like credit screening and more like blocking the deal.
How to Request Consent Without Losing the Right
Sloppy paperwork can turn a valid transfer into grounds for eviction. The mechanics matter.
What to Send
Your landlord needs enough information to evaluate the proposed tenant the way they’d evaluate any new applicant: full name, current address, employment details, and financial background, usually with recent pay stubs, a credit report, and references. If the lease specifies required documentation, follow it exactly, because omitting a required item gives the landlord a reason to stall.
Alongside the candidate’s information, send a written request for consent that states the proposed terms: start date, end date, monthly rent, and whether you are proposing an assignment or a sublease. Vague requests invite vague responses, and unclear terms create disputes later about what was actually agreed to.
How to Send It, and When to Expect an Answer
Use a delivery method that generates proof of receipt. Certified mail with a return receipt is the standard approach because it documents the delivery date and the recipient’s signature.1United States Postal Service. Return Receipt – The Basics Many leases and local laws give the landlord a set number of days to respond, often thirty, though your lease may specify a different window.
If the landlord doesn’t respond within the required period, some jurisdictions treat silence as implied consent. During the review window, the landlord may ask for more information about the proposed tenant, which is generally permitted as long as the requests are reasonable rather than a stalling tactic. Keep copies of every piece of correspondence. If a dispute reaches court, the paper trail is your evidence that you followed the process.
Who Stays Liable After the Transfer
This is where most tenants get an unpleasant surprise. Handing over the space does not, by itself, end your obligations to the landlord.
Sublease
You remain fully liable to the landlord for everything: rent, property damage, lease violations, all of it. You are still in direct contract with the landlord, and the sublessee’s existence does not change that. If the sublessee stops paying, the landlord collects from you. If the sublessee causes damage through negligence, the landlord can hold you responsible even if you had no knowledge of what was happening in the unit.
A sublease also cannot grant the sublessee more rights than your lease gives you. If your lease prohibits pets or limits occupancy, your sublease cannot override those terms. When terms conflict, the master lease wins, and any violation your sublessee commits is also your violation as far as the landlord is concerned.
Assignment
Assignment is slightly better but still risky. The new tenant takes on a direct relationship with the landlord through what the law calls privity of estate, so the landlord can enforce lease covenants against the assignee directly. Your original contractual obligation, however, does not vanish. Courts have consistently held that the original tenant remains liable under privity of contract for the entire lease term unless formally released.
Novation: The Only Clean Exit
The only reliable way to end all liability is a novation. This is a three-party agreement in which the landlord, you, and the new tenant sign a document that explicitly releases you from every obligation under the lease and substitutes the new tenant in your place. The landlord agrees to look solely to the new tenant going forward.
Landlords are not required to agree to a novation, and many will not, because keeping the original tenant as a backup guarantor reduces their risk. If you are assigning your lease and want a clean exit, ask for one in writing, and understand that a consent-to-assign is not the same thing.
Money Questions That Come Up During a Transfer
Profit on a Sublease
When market rents rise, a sublease can turn into income. If you pay $2,000 a month and the market rate is now $2,500, you might sublet at the higher figure and keep the difference. Many commercial leases include a profit-sharing clause that entitles the landlord to a portion of any premium above your own rent. A 50/50 split of the excess, after deducting reasonable expenses like broker commissions and legal fees, is the most common formula. Some leases take 100 percent of the surplus; others waive any claim to it. If your lease is silent, the profit generally belongs to you, but confirm against your specific agreement before counting on that income.
Security Deposits
In a sublease, the landlord still holds your original deposit and will apply it to any damage at the end of the master lease. Damage caused by your sublessee can eat into your deposit with no automatic recourse against the sublessee. Collect a separate deposit from your sublessee to cover that risk. If you do, many states require you to follow the same rules a landlord follows: hold the deposit in a separate account, provide an itemized statement of deductions, and return the balance within the statutory window after move-out. Handling a sublessee’s deposit casually can expose you to statutory penalties.
In an assignment with a novation, the cleanest approach is for the landlord to return your deposit after a move-out inspection and collect a new one from the assignee. Without a novation, your deposit usually stays with the landlord, and you negotiate reimbursement from the assignee as part of your private assignment agreement.
Insurance
Your renters insurance almost certainly does not cover a sublessee’s personal property or liability. The sublessee needs their own policy, and you should require it in the sublease agreement. Check with your own insurer too, because some carriers treat an extended absence as a coverage change, and subletting without notifying them could void your policy.
Taxes on Sublease Income
Money you receive from a sublessee is rental income, and the IRS expects you to report it. Any cash or fair market value of property or services received for the use of real estate counts as taxable rental income. Report it on Schedule E of Form 1040. If you use the cash method of accounting, as most individuals do, you count the income when you receive it, not when it is due, and advance rent counts in the year you receive it regardless of what period it covers.2Internal Revenue Service. Topic no. 414, Rental Income and Expenses You can deduct reasonable expenses tied to the sublease, such as advertising, a portion of your rent attributable to the sublet space, or minor repairs to prepare the unit.
If You Skip Consent
Transferring without the required consent is a breach of the lease. The landlord can treat the unauthorized transfer as grounds for eviction of both you and whoever moved in. Even if the sublessee pays on time and keeps the place in good shape, the procedural violation alone supports termination. The landlord may also pursue a damages claim for any losses caused by the unauthorized transfer.
If someone has already moved in without permission, the best move is to submit a formal consent request right away and hope the landlord ratifies the arrangement after the fact. Some will, particularly if the new occupant is creditworthy and the rent is current. At that point you are asking for a favor, not exercising a right.
