My lawyer also said i need to show proof that i paid the rent for this month by showing bank statement or rent reciept. Is that required? Because what if the landlord is a relative and agrees to not take rent for a couple of months as he knows our money is tight due to the high visa fees?
Nope, you don't need that either. Sounds like your lawyer doesn't know what they're talking about!
Literally ALL you need is:
- valid tenancy agreement
- letter from the landlord giving the visa applicant permission to live in the property too if they are not named on the tenancy
Council tax and utility bills do not prove you have the landlord's permission to live in the property, so they are not required at all.
