Do I legally own the laptop?

So, back in 2023, my mother bought me a laptop after I was terminated from my first job. She got the money from her pahulugan from a foundation. But then I gave her around 7k on my first salary (she took it from half of my salary without asking me at all). Then every month after that back in 2023, I gave her around 4k, and I also paid for the internet worth 1,700 per month. I was earning a total of 20k per month back then. Then she also asks me for money for her pahulugan sometimes, as well as for the sack of rice. But now that I "own" the laptop, she's telling me that I did not contribute anything to her and that she bought the laptop with her own money (wala syang work or other source of income other than sari-sari store goods that she buys from my father's money or her loans). The money that I gave her then was for the laba day she does every Saturday, and for the electricity and water and food I eat (where sometimes we still don't have ulam kahit nagbibigay ako ng pera. I rememember one time nagbaon ako ng panis na kanin sa first job ko, then sometimes I also take at work mga ulam na bigay lang ng kamag-anak or mga ininit na na ulam kahit nagbigay ako ng pera). The question is what should I do with this type of parent and who should own the laptop? I have no records of the previous money that I handed out na.
