Housing help

[2children47]

Hi everyone,
Im looking to move house and have given the landlord the required 2 month notice. Universal credit has asked I send them the new contract(not done since under notice) or they will stop my housing. How do I explain as notice given informally via whatsApp 🤔

Are they asking for the contract on your next place?

no, the current one

What do they want it for? I'm confused why they don't want the new one? Do they mean they want confirmation of the end of the tenancy?
