Key Takeaways
Our Verdict
Subletting works best when you need a temporary arrangement and are comfortable retaining legal responsibility. A lease assignment is the cleaner exit when you want to walk away entirely — provided your landlord approves and your lease allows it. Neither option is universally better; the right choice depends on your timeline, your lease terms, and how much ongoing risk you're willing to carry.
| Best for | Recommended |
|---|---|
| Renters leaving temporarily (semester abroad, work travel) | Subletting |
| Renters relocating permanently and wanting a full exit | Lease Takeover (Assignment) |
| Those wanting minimal ongoing financial exposure | Lease Takeover (Assignment) |
| Those in states or buildings with sublet-friendly policies | Subletting |
What's the Difference?
Both subletting and lease takeovers let you vacate a rental before your lease ends — but they work very differently under the law.
Subletting (also called subleasing) means you rent your unit to someone else — the subtenant — while your name stays on the original lease. You remain the primary tenant in your landlord's eyes. If the subtenant stops paying rent or causes damage, you're on the hook.
A lease takeover, formally called a lease assignment, transfers your entire lease to a new tenant. Once the assignment is complete and your landlord approves, you step out of the lease entirely. The incoming tenant takes on all rights and obligations directly.
Think of it this way: subletting is like lending a friend your library card — you're still responsible if they rack up fines. An assignment is like transferring the card to their name permanently.

How They Compare Across Key Factors
The table below breaks down how subletting and lease assignments differ across the factors that matter most to renters making this decision.
| Subletting | Lease Takeover (Assignment) | |
|---|---|---|
| Original tenant's liability | Remains fully liable | Liability transfers to new tenant |
| Length of arrangement | Typically temporary | Permanent for lease term |
| Landlord approval required | Almost always yes | Almost always yes |
| Who pays rent to landlord | Original tenant (collects from subtenant) | New tenant pays directly |
| Ease of reclaiming unit | Possible if subtenant agrees | Not possible — rights transferred |
| Best use case | Temporary absence (months) | Permanent relocation or exit |
As the table shows, the most significant practical difference is ongoing liability. Many renters choose a sublet thinking it gets them off the hook — but legally, it does not.
Landlord Approval: The Step You Cannot Skip
Whether you sublet or assign, your landlord's written consent is almost always required. Most standard leases include a clause prohibiting either arrangement without prior approval. Proceeding without it can be grounds for eviction — of both you and the person you brought in.
Always Request Approval in Writing
Send your landlord a formal written request — email is acceptable in most states — before any new person moves in. Keep a copy of the request and any response. Verbal agreements are difficult to enforce and leave you with no documentation if a dispute arises later.
Some states, including New York and California, limit a landlord's ability to unreasonably withhold consent to a sublet or assignment. However, what counts as "unreasonable" is defined by state law and sometimes local ordinance — it's not a blanket right. Check your state's tenant protection statutes or consult a local tenant advocacy organization before assuming approval will be granted.
When you request approval, put everything in writing. Provide the prospective subtenant's or assignee's name, employment information, and references. A formal written request creates a paper trail and, in some states, starts a legal clock on how long the landlord has to respond.

Risk, Liability, and What Can Go Wrong
Understanding who bears the risk is the core of this decision.
Subletting Risks
- Unpaid rent: If your subtenant misses a payment, your landlord will come to you — not them.
- Property damage: You may be responsible for damage caused by someone you brought in.
- Difficulty removing a bad subtenant: In some states, a subtenant gains certain tenant rights and cannot simply be asked to leave.
Lease Assignment Risks
- Landlord denial: If the landlord rejects the incoming tenant, you may be stuck paying rent on a unit you can't occupy.
- Some leases include recourse clauses: A small number of assignment agreements retain the original tenant as a backup obligor — read the fine print carefully.
Don't Assume a Handshake Deal Is Enough
Informal arrangements — where a friend takes over your apartment without notifying the landlord — can backfire badly. The landlord can pursue you for back rent, terminate the lease for unauthorized occupancy, or initiate eviction proceedings. Even if things run smoothly at first, you remain exposed for the full lease term.

How to Protect Yourself Whichever Path You Choose
Regardless of which route you take, a few practices significantly reduce your exposure:
- Get every agreement in writing. A sublet should include a written sublease agreement. An assignment should be documented with a signed lease assignment form — often provided by the landlord.
- Screen your subtenant or assignee carefully. Request references, verify income, and treat this process the way a landlord would.
- Collect a security deposit from your subtenant (where legal in your state) to protect against damage or missed rent.
- Notify your renter's insurance provider. Standard renter's insurance may not cover a subtenant's belongings or liability — check your policy.
- Document the unit's condition with dated photos before the new occupant moves in.
