May my grandmother take my laptop away?

Following the last argument (see), I moved more or less voluntarily to my father today, because everything was not bearable for me, but as I had not expected otherwise, my grandmother has messed up my life again…

So in a nutshell, half a year ago, she bought me a new laptop (the old one dated about 1990 or so) so I could do my work for my seminars, she knows I'm doing only schoolwork and when I'm moving out she took the laptop away from me and hid it! By Tuesday I have to have both a commented outline and an exposé for my W-Seminar have made otherwise I have this semester with 0 points virtually nothing and will not be admitted to the Abitur. My whole work of my two seminars is on this laptop and she even refuses to let me copy the data. I have no idea what to do, I know that she can take it away from me temporarily only in educational measures, as I told her, she laughed at me but only mischievous and said "but now I have him what you want So you do, call the police? ".

I've had enough! She will certainly not push the laptop out and tries to destroy my life at will.

What can I do to get my laptop back to Monday?! That is really urgent

In this case, I do not care about any legal measures, the main thing is that I can finish everything else I'm done! Unfortunately I really do not know how to proceed, should I really report the incident to the police?

How old are you?

Vlt. Can your dad pick up the laptop? Or at least pull the data?

If it was a gift and you do not have child custody, you can even ask for it with the police. Or your father.

I'm 16, in a few months 17.

No, my dad can't copy the data from this laptop or take the laptop with him…

I had rather hoped that there would be a legal way for this, because I would not get the laptop even though it is technically my property, as I said, my grandmother is trying to strike a final blow at me

Thank you.

Your father can't prevail against your grandmother? I would tell something to the woman.

Unfortunately, nothing helps, the woman literally lives in her own world and has been doing my whole family since I can think

She even threatened me with a knife… But that's less relevant in this case

Ask your parents. Maybe the police can actually do something, but I think it's unlikely.

Learn from it for the future and always make copies. Computers like to give up the ghost.

What would she do if your father arrived with a stick?

If all else fails, tell that on Monday at school. Vlt. Can the appointment be postponed? Or can you reach a teacher now?

The files would not fit on a stick, it should be here around a few gigabytes and I have only the standard 16Gb parts, also I would not help me if I have no laptop to carry on with everything.

When he made the offer to make a copy of the files and she then keeps the laptop, the answer was no and we were thrown out of the apartment.

legally she has no custody but my mother, but nevertheless I live since I can remember her since she took me away as a toddler of my mother, but since then my mother lives through my grandmother in a 2-family apartment, but that is another story

I think I'll actually turn to the police, I'm afraid that if this is a full-blown lawsuit, my father will rather give up…

Oh you ever…

Then only a conversation with the school remains.

I'm afraid too
