Sublease Agreement
What to check in a sublease or roommate agreement
A sublease or roommate agreement sits on top of another lease, and that is where most of the risk comes from. First confirm the arrangement is allowed: many leases need the landlord’s written consent, and without it you could be asked to leave even if you pay on time. Ask to read the master lease, because its rules usually still apply to you and your rights generally end if it ends. Then check how rent is split and who pays the landlord, who holds the deposit and how it comes back, and how utilities and other shared costs are divided. The end date should fit inside the master lease term. Look for early-exit terms, notice periods, guest and pet rules, and who pays for damage. If everyone signed the main lease, each person may owe the full rent when one stops paying. Renters, subtenants, and primary tenants can upload a sublease or roommate agreement PDF, DOCX, or TXT to Contract Analyzer for a structured score, verdict, findings, missing clauses, and key terms.

Red flags
Watch for these issues in a sublease agreement.
- No mention of landlord consent when the master lease requires it
- You have not been given a copy of the master lease
- Sublease term runs past the end of the master lease
- Deposit paid to the primary tenant with no return terms
- Liability for damage or rent caused by other occupants
- No early-exit right, or a penalty equal to all remaining rent
- Utilities and shared bills split with no clear method
- Primary tenant can end the arrangement on short or no notice
Red flags are starting points, not automatic deal-breakers. Context matters: a harsh clause may be negotiable, industry-standard, or offset elsewhere in the document. Use them to prioritize what you verify next — then confirm the exact wording in your file. For a general pre-sign frame, see the contract checker checklist.
Key clauses
Clauses worth locating before you commit.
Knowing the clause names helps you search the PDF and ask sharper questions. If a listed clause is absent, that absence itself may be the finding — especially for termination, liability, payment timing, or confidentiality scope.
Contract Analyzer surfaces many of these as findings or missing-clause notes in a structured report.

FAQ
Questions about sublease agreement review
Do I need the landlord’s permission to sublet?
Often yes. Many leases ban subletting without written consent, and some places limit when a landlord can refuse. Check the master lease and get any consent in writing.
What happens to my sublease if the main tenant stops paying?
Your right to stay usually depends on the master lease, so the landlord may be able to end it even if you paid. Ask for proof of payment, or pay the landlord directly if that is allowed.
What is joint and several liability?
It means each tenant can be held responsible for the full rent, not just their share. If your roommate leaves, the landlord can usually ask you for all of it.
How is a roommate agreement different from a sublease?
A sublease gives someone the right to live in a place rented by another tenant. A roommate agreement sets rules between people sharing a home and usually does not bind the landlord.
Can Contract Analyzer review an informal roommate agreement?
Yes, if you have it as a PDF, DOCX, or TXT. You get an informational report on gaps and risks, which is useful because informal agreements often leave out key terms.
