Can a Parent Disinherit a Child or Grandchild?
Therefore, if you wish to disinherit any of your children or grandchildren, then your Will must rebut any legal presumption that these children or grandchildren were simply forgotten. To do this, your Will should specifically and expressly name the children (and any grandchildren whose parent, i.e., your child, has died) who you intend to disinherit, and also expressly state that these children and/or grandchildren are not to receive anything under your Will. Doing so will prevent a disinherited child or grandchild from claiming that they were mistakenly left out of your Will.
It's perfectly legal to disinherit one or more of your children or grandchildren in your Will. This is often done where a parent has already provided for a child elsewhere –through a large gift or a prearranged trust, for instance. But it’s not necessary that your excluded child be provided for elsewhere, which means you’re completely free to leave nothing at all to any or all of your children if you desire.
For the reasons set forth above, It's important that you update your Will any time you have a new child (either through birth or legal adoption).
