My question involves landlord-tenant law in the State of: California
I currently live in my Grandmother's house who lives out of the country and have taken care of the house for five years. I started renting two rooms 3 years ago and have run into a problem with a roommate. I fear I need to give them a notice and have a strong feeling they may squat. I did not properly do a lot of things (Sound paperwork, reference check, etc) Can anyone give me advice on my situation?
1. Grandmother is on the grant deed
2. I have no lease or paperwork with my grandmother
3. I have a basic lease agreement with my roommate stating I am the landlord
4. I recently gave the roommate a 30 day-notice to amend the original agreement to include paying for the utilities (This agreement is a lease that expired, the roommate refused to resign a new lease)
5. On the rental form, I believe their information is fake (permanent address is not real) and I failed to get a copy of the roommates license.
The roommate is refusing to pay the utilities and arguing my contract does not allow for an increase because it is a lease (It's a six month lease that expired a year ago).
I am going to give them a 60-day notice to leave (They have lived here for 1.5 year). If the person pays the rent and does not pay the utilities, will I be able to legally evict the roommate in court? Also, do I need to get a power of attorney first?
Every time I try to serve the roommate papers to talk about our agreement or discuss the issue, the person intentionally avoid me or pretends not to hear me. This is very stressful and I do not know if I properly served them papers if they keep running away and will not accept any paperwork from me.
The reason I am wondering is because I want this roommate to leave as soon as possible because I feel very uncomfortable with this individual in my family home and have a complicated situation. I would like the fastest and safest way to have legally have them leave, thank you for reading this.
