What is subletting?

Subletting occurs when a primary tenant rents the apartment or parts of it temporarily to a third person. For tenants this means: you remain the contractual partner of the landlord but bear responsibility for the subtenant and the apartment. Clear agreements reduce later conflicts and provide legal certainty.

In many cases landlord consent is required.

Landlord consent

In many tenancy relationships landlord consent for subletting is legally required. Obtain this consent in writing and document the date and content of the permission. Without consent there may be legal risks up to termination of the main lease.[1]

Request consent in writing so you have proof.

Sublease agreement: content & form

A written sublease agreement creates clarity. It should specify duration, rent, deposit and responsibilities for damages. Pay attention to clear wording on move-in, move-out and the use of furniture or shared areas.[2]

  • Duration of the sublease (time)
  • Rent, payment method and due dates (rent)
  • Deposit agreement (deposit)
  • Keys, access and house rules (entry)
  • Rules on liability and damages
Record all agreements in writing, even if they were made verbally.

Deposit and liability

Clearly agree if and how much deposit is required and how deductions for damages will be handled. Keep receipts and document the condition of the apartment at handover with dated photos.

  • Set deposit amount and repayment deadline
  • Create a condition report with photos
  • Keep receipts for payments
Keep all receipts at least as long as the sublease lasts.

Practical steps before starting subletting

  • Obtain landlord consent in writing (form)
  • Take photos of the apartment condition (evidence)
  • Document all agreements and payments (record)
  • Note deadlines and duration in your calendar (time)
Good documentation makes it easier to resolve disputes later.

FAQ

Do I always need landlord consent?
Not always, but in many cases yes. Check your main lease for clauses on subletting and obtain written permission if in doubt.[1]
What should a sublease contract include at minimum?
Names of the parties, duration, rent, payment method, deposit, rules on damages and termination periods.
Who is liable for damages caused by the subtenant?
The primary tenant remains responsible towards the landlord; resolve internal liability and possible recourse claims separately.
