Generally, all adults should have a Will. As we age, we might have a family and accumulate more wealth and either of these circumstances make it more urgent that we have a Will.
Without a Will, you have no say or control. The court appoints someone to be guardian for your minor children and to administer your estate. Your assets are distributed according to your states’ rules.
A class is a way of referring to a group of people as they are related to you in the same way. Common examples are children, grandchildren, siblings, or nieces/nephews.
As long as you do not want to exclude any member of the class, it is easier to just name the class. If you want to exclude one member of the class, then you have to name each member individually. For example, if you are writing your Will and your daughter is pregnant with her third child, it’s easier to name a class. In the will you could give gifts to child A and child B but you couldn’t give to the expected baby (child C) because that child does not have a name yet. However, if you gave a gift to “grandchildren” child A, B and C would benefit.
You should name individuals when you only want to benefit certain members of a class or you want them to benefit differently. For example, if you want to name only one of your children or if you want each member of a class to have a greater or a smaller share of your assets.
