Abandonment in legal terms means when someone leaves behind or completely stops caring for their property or responsibilities without any intention of coming back.
Think of it like when you have a toy that you used to love playing with but now it's just sitting in the corner collecting dust. The toy has been abandoned because you have stopped taking care of it and stopped playing with it.
Sometimes adults abandon things like their houses or their pets. For example, if someone moves away from their house and leaves it empty for a very long time and stops paying for it, then it is considered abandoned.
Abandonment can also happen with people. If a parent doesn't take care of their child and doesn't see or talk to them for a long time, it can be considered abandonment.
When something is abandoned, other people might be able to take over ownership. So, if someone abandons their house or car, someone else might be allowed to take it over and use it. However, this can only happen if the abandonment is legal and properly determined by a court.
