I was asked by my sister to move in over a year ago to help her out around the house. I was paying her $125 a week and doing 1/2 of the groceries as well. She sent me a text advising me of a 30 day notice. What are my rights in this situation? I get mail there, I keep a slip from DMV for my change of address and I have furniture / other belongings there.

By the way this is in Virginia.

Spells it out. Pg4, :30 day notice

You have the right to proper notice. Apparently she is giving you your rights. Though it might be better if it was in writing instead of a text.

What makes you think you have any more right than that.

Is your sister being evicted also? Or just you?
