House Hacking with a SO living with me

[Jack Carrozzi]

I am looking at house-hacking and living in one of the units with my girlfriend but she wants to be able to have some sort of paperwork showing that she lives there but not as a separate tenant. Also if something is to happen to me what will happen to the property and will she get kicked out of the property or have to take over the landlord position? Looking for any information. Thanks!
