The behavior of family members is nothing more than occupying the property of the elderly, but they are unwilling to do their duty to take care of or support the elderly. The law will eventually make a negative evaluation of this behavior. Therefore, it will not have much impact on the future results.
The behavior of the elderly belongs to intentional guardianship in law, also called entrusted guardianship.
It means that an adult with full capacity for civil conduct determines his guardian in writing, and when the adult loses or partially loses his capacity for civil conduct, the guardian will perform his guardianship duties. Simply put, intentional guardianship means that you can designate a person as a guardian in writing after you are disabled, take care of your life and dispose of your property and rights.
This kind of behavior belongs to the legal rights of the elderly and should be respected.
