What if I don't want to sign the agreement at all?
You can decline it. The tenancy doesn't go ahead through Tenarize, and your landlord can revoke the document and start again.
You're not obliged to sign. Declining sends your reason to your landlord and leaves the tenancy inactive — no start date is set, and no rent becomes collectable.
Your landlord can then put the tenancy back a stage, change the terms and send a revised agreement, or not proceed. Nothing about the arrangement takes effect through Tenarize until both signatures are in.
Worth knowing: If you've already moved in or paid money, declining a document doesn't undo that. Take advice from Citizens Advice or Shelter if you're unsure where you stand.
