Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Did you ever live at the property?
Do you and your mother share the same initial?
Has she actually received court documentation?
They are entitled to try and trace you and writing to your family members is an acceptable option I am afraid.
Your mother should simply send the paperwork back and request that they do not use her address again.
If they do then that IS harassment
Please ask if you need further details
