Hereditary property is something that your family members or ancestors own and you might inherit it from them when they pass away. Just like how you might inherit your mom's eyes or your dad's hair color, you could also get property from your family. This property can be anything like a house, car, land, or even money.
Let's pretend that your grandpa owns a big piece of land with a farm on it. When he becomes very old and passes away, his property will be passed on to his children (your mom/dad). If your mom/dad has siblings, they will also share the property with them, and then all of them become the new owners of the farm.
This property is hereditary because it's being passed down from one generation to another. So if something were to happen to your mom/dad, you and your siblings (if you have any) would also have a share in the property.
In simpler terms, hereditary property is like your family's treasure that can be passed down to you, just like a grandma's secret cookie recipe that you can later use and pass on to your kids.
