Can I be picked up from my mom's house as a date since I am an adult?
So she's kind of been reluctant in people knowing where she lives. And from my understanding you can just leave if you want but when it comes to her house. And since yeah it's her house I do wonder where the boundary lays. So I am an adult yes and my mom is out right now with my sister taking care of me and staying around the house which has me worried but she said she would be back either Sunday or Monday and I'm planning on taking my chances Sunday. But seriously what is the rules as it comes down to there are cameras my sister has access to so I think she might see me leaving anyway and question me on this. So what exactly are my rights as an adult? Can someone pick me up in the driveway and we just leave together and then come back home? I do think even if I leave and come back home that can show some form of trust and then I can eventually tell my mom what I did when she gets back home. I even hope I can use my recent birthday as an excuse to start dating. But the main point I want to bring up is if I can tell someone where I live and have them pick me up outside the house?
There's no legal reason you can't do whatever you want.
There's also no legal reason for your mom and sister to let you keep living there.
The worst-case scenario is that your mother kicks you out of the house. Which, in my opinion, wouldn't be a bad thing for you if they do this because they're upset you went on a date.
She can't just kick OP out, OP is an adult and thus legally a tenant. If OP's mom wants OP gone, she has to go through the formal eviction process and serve proper notice.
Depending on where OP is, that's not strictly true. If you are in a situation such as this, at least within the UK, you are not strictly entitled to the rights of a tenant if you do not pay rent nor do anything in lieu of rent.
Basically in the UK if you do not have a tenancy agreement, cohabitation agreement, or license to occupy, then it can start getting very complicated. If they were named as a property owner, or had a common understanding of financial interest in the property, they might be able to fight for a stake of the house, but that isn't really the point here. In the end whether they can be kicked out legally is a complex issue (at least in the UK) and not really a question we could answer here.
Sure, but I think it's reasonable to assume OP is in the US, given that they used mom and not mum. At the very least, it's unlikely they're in the UK (or Australia or Canada).
Point still stands (at least depending on state) that without a residential lease agreement in the US then generally you would be considered a guest in your family's house if over the age of 18. As such OP could be fairly easily evicted.
Nope, it defaults to an informal tenancy if they've been living there long enough (usually something like 3 months), and this includes the time when they were under 18. So if a child grows up in the home, they automatically become a tenant at 18. This is also regardless of whether they actually pay rent.
You don't need a written contract for there to be a contract in place.
Informal tenancies seem to be state-dependant from what I can find (more concrete in california and florida), though I'd be fascinated to see if this has been legislated or litigated upon more generally. Of course verbal contracts are valid contracts, but that's the sort of thing that would probably have to be sorted out in court.
In the end as advice for OP, I stand by the opinion that "they can't kick you out without notice" is not a good idea to base one's decisions on. You could be kicked out, whether it is legal or not, and the legality of such a no-notice kick out on a verbal and informal contract is certainly not an entirely non-disputed concept in all states.
OP could get kicked out, and maybe they could take their mother to court to try and get that solved eventually, but in the immediate they would end up houseless and in a pretty dire situation.
OP asked what their rights were, so that was the focus of my reply. You're right though, and I've said as much in my main comment, it's better to avoid the situation entirely than to stick a finger up and try to assert your rights.
