Hello my name is ***** ***** I will help you with this.
Could you please explain the situation a little more?
My mum is in hospital and my dad has gone to live with my auntie. My auntie has changed the lock to the house I share part time with my parents. I pay all the bills as rent. I just want to get in to get my stuff back. I have also so found out that my key which fits the side door I am allowed to enter the house.
Do you rent the whole house or does your auntie live there?
