Justipedia explains Immediate Family
Often, property is passed between immediate family members. This is frequently the case when a person leaves a last will and testament. If property is left by a decedent to an immediate family member through a will, that property will legally become theirs. However, estate taxes may be applicable. Whether or not a person is an immediate family member can also be important for things such as hospital visitation and other similar matters.
