Adding new tenant to agreement

[I thought this would be an obvious topic but couldn’t find any relevant post or FAQ, please do redirect me if you know of one] In short: my tenant has a new partner and would like to add them to the tenancy. Is there a way to do this that doesn’t involve starting everything from scratch, including tenant fees, deposits, referencing, etc? Cheers, Rob

As for a minor child you’d never put them on the lease. What would be the reason for doing so?
