Deed of Gift - 50/50

General Discussion

Property owned outright - no mortgage - Sole ownership, considering Deed of Gift 50/50 split with spouse.
Implications, changes needed to cover Tenancy, Insurances, Deposit, notify IF any Agents involved etc.

What changes are required to ensure the AST Tenancy Agreement, Insurances, Agents if any these continue all interrupted without any surprises later ?

Notify Tenants or not as I believe although 50/50 we can still use the same sole name as landlord OR if you split 55 / 45 with the original Landlord as the majority owner is this a little easier to manage ?

Section 3
Section 48 - Still the same address

Deposit - No Change needed ? IF we can retain same person as the Landlord, no address change
IF ownership is changed, although from spouse to married couple IS there something I am missing at my peril ?

I hope this is a simple task, yet I would like to know the pitfalls before I jump !

Thank you.
