Typically, if my client has a child or children and anticipates having a child or additional children, a simple statement in the Last Will and Testament which reads “any after born children” will provide for any children born after the Last Will and Testament has been signed. I usually include this statement even if the couple does not have children; this way when they do have children they are already provided for and my client does not have to pay me again to make the change to the Last Will and Testament.
