What is Antilapse Statute?

Legal Definition
Under normal estate law, a gift will "lapse" (no longer exist, the gift returns to the will residuary) if the beneficiary predeceases the testator (if the person receiving the gift dies before the person who wrote the will, there is no gift).

Certain states have enacted "antilapse statutes", under which the gift will pass through the deceased beneficiary and go to their heirs. For example: "Grandfather" leaves $100 to his son, "Son", but Son dies before Grandfather. If there is no antilapse statute, the $100 remains in the estate; but if there is an antilapse statute, the $100 will pass on to Son's heirs, namely "Grandson."
Legal Definition
An anti-lapse statute is a rule of construction in trusts and estates law. If a testator devises a gift to a person in his will and the devisee predeceases the testator, the anti-lapse statute will allow the gift to pass on to the devisee’s descendants rather than force the gift to pass through intestacy.
