Sub Lease Meaning: What a Sublease Is and How to Write One

A sublease is a lease inside a lease: the current tenant keeps the original agreement and rents the space, or part of it, to someone new, who pays the tenant instead of the landlord. Here is the definition you can copy, the clauses a sublease must contain, and the fastest way to draft, sign, and file one.

Copy-ready definition:

• Sublease: a second lease in which the original tenant (sublandlord) rents all or part of the leased premises to a subtenant for a period that ends on or before the original lease term.

• Who stays liable: the original tenant. The landlord can still pursue them for rent, damage, or breach, even after the subtenant moves in.

• What makes it legal: the head lease must allow subletting, or the landlord must consent in writing.

Sub Lease Meaning in Plain Terms

Three parties, two leases, one address. The landlord leases to the tenant, the tenant leases to the subtenant, and the subtenant has no contract with the landlord unless one is added.

That structure decides who handles what. The subtenant pays rent to the tenant, reports repairs to the tenant, and follows the house rules in the head lease, which are usually copied into the sublease. The tenant keeps paying the landlord on the first of the month whether or not the subtenant pays them, which is the risk most sublandlords underestimate.

Sublease and assignment are not the same thing. In an assignment, the new tenant takes over the remaining term and the original tenant steps out of the contract; in a sublease, the original tenant stays on the hook and the new occupant sits under them. If a lease bans assignment but permits subletting, the difference is the whole point of the clause.

What a Sublease Agreement Must State

Write the sublease so a stranger could enforce it without asking you a question. These eight items do that.

1. All three parties, with the landlord named as consenting party or referenced in an attached consent letter.

2. The premises, including whether the subtenant gets the whole unit or one room, plus any storage or parking.

3. The term, with a start and end date that fall inside the head lease — a sublease that outlives the head lease is a defect.

4. Rent, due date, and payment method, stated as a number and in words.

5. Deposit and return terms, including who holds it and what is deducted.

6. Utilities and internet, naming who pays which account and how the amount is split.

7. House rules and use, copied from the head lease: pets, noise, guests, smoking, short-term letting.

8. Condition and signatures, with a photo inventory attached and every page initialled.

Before any of that, confirm you are allowed to sublet. Open the head lease, search for “assignment and subletting”, and read what follows: some clauses require written consent, some set a notice period, and some ban it outright. A short message to the landlord, answered in writing, is worth more than any clause you draft yourself. City rules on short lets and rent-controlled units can apply on top of the lease.

How to Draft and Sign the Sublease in WPS Writer

Draft it as a document, not a chat message. You want numbered clauses, initials on each page, and one PDF that both sides can keep.

1. Start from a template. Open a rental or lease template in WPS Writer and delete what does not apply, rather than typing from a blank page.

2. Replace every bracketed field and delete the brackets, so nothing looks unfinished when the subtenant signs.

3. Number the clauses and add a short contents line if the document runs past three pages.

4. Attach the inventory as photos with a date and a one-line description of each room.

5. Save as DOCX for edits, export a PDF for signing, then keep both: the DOCX for next time, the PDF as the record.

Sign in the same session if you can — a PDF signature added after the subtenant has already signed looks like a revision, and some landlords will ask for the document to be redone.

Sublease Rent Math: What to Charge and What to Disclose

Most subleases are priced from the head rent upward, which is fine until the subtenant compares notes with the landlord. Set the number deliberately and disclose it.

Line	Example	What to write in the sublease
Head rent	$1,850 per month	Not required, but a consent letter usually discloses it
Utilities share	$140 average	Fixed amount or split percentage, plus what happens in a heat wave
Sublease rent	$2,050 per month	Number, due date, late fee, payment method
Deposit	One month	Who holds it, what it covers, return deadline

A markup covers your risk: you remain liable for the whole rent, and you carry the cost of a vacancy between subtenants. Keep the markup explainable, because a subtenant who learns the head rent after signing will assume they were misled. A few cities also cap what a rent-controlled unit can be sublet for, and platforms that list whole units for short stays now report host data to local authorities, so the rent you charge is more visible than it used to be.

A sublease is three documents that have to agree with each other: the head lease, the sublease, and the consent letter. Keeping them in one editor is how you catch the clause that contradicts the other two.

• Draft and compare: open the head lease and your sublease side by side in Writer, and copy the house rules instead of retyping them.

• Sign and send as PDF: add a signature, attach the photo inventory, and export one file the subtenant can keep.

• Free, on every device: the same file opens on Windows, macOS, Android, and iOS, so the subtenant can review before signing.

If you need a starting point, the rental lease templates cover the clauses a sublease borrows, and the rental agreement types explain which one fits a room rental versus a whole unit.

FAQs

Does a sublease need the landlord’s permission?

Usually yes, unless the head lease allows subletting without consent. Most leases require written consent, and a sublease signed without it can be terminated even if the subtenant pays on time.

Is a sublease the same as an assignment?

No. An assignment transfers the rest of the term to a new tenant and releases the original tenant; a sublease leaves the original tenant liable and creates a second, shorter lease underneath.

Can a subtenant stay after the head lease ends?

No. A sublease cannot outlast the lease it sits under. If the head lease ends, the subtenant’s right to occupy ends with it unless they sign a new agreement with the landlord.

Should a sublease be notarized?

Not always, but notarization helps if the sublease will be used as proof of residence or attached to a court filing. Check what the landlord, building, or local authority expects.

What should a sublease say about the deposit?

State who holds the deposit, how much it is, what it can be deducted for, and when it must be returned. If the tenant holds it, the subtenant should know the landlord has no obligation to return it.
