The answer is in Massachusetts nothing prevents you under the Law from leaving one or all of your children out of your Will. You should generally use specific language to identify the child you wish to disinherit. There are some limitations with that, but there are more difficulties now under the new probate code; which if there is not a surviving spouse at all, then there are some issues in terms of being able to completely disinherit children and this is under the Massachusetts General Laws, Chapter 190B Section 2403.
