After Death Planning: "Will Limitations"

Some legal restrictions prevent a testator from giving full effect to his or her wishes. Some laws prohibit disinheritance of spouses or dependent children. A married person cannot completely disinherit a spouse without the spouse's consent, usually in a prenuptial agreement. In most jurisdictions, a surviving spouse has a right of election, which allows the spouse to take a legally determined percentage (up to one-half) of the estate when he or she is dissatisfied with the will. Nondependent children may be disinherited, but this preference should be clearly stated in the will in order to avoid confusion and possible legal challenges.
