The Antilapse Safety Net
Life does not always follow the plan. A beneficiary named in a will may pass away before the person who wrote it. When that happens, the gift does not automatically vanish. Arizona's antilapse statute steps in and redirects the gift to the deceased beneficiary's own descendants, as long as the beneficiary falls within a qualifying relationship.
If a beneficiary fails to survive the decedent and is a grandparent, a descendant of a grandparent or a stepchild of the decedent, the following apply: Except as provided in paragraph 4 of this subsection, if the beneficiary designation is not in the form of a class gift and the deceased beneficiary leaves surviving descendants, a substitute gift is created in the beneficiary's surviving descendants.
A.R.S. § 14-2706(A)(1)The substitute beneficiaries take the gift by representation, meaning they receive what their parent or grandparent would have received. This keeps the property within the family line rather than falling back into the residuary estate or passing by intestacy.
When the Rule Does Not Apply
Survivorship language can override the antilapse rule. If a will says "to my brother, if he survives me," Arizona law treats that as a sufficient indication that the person intended to prevent the substitute gift from taking effect. The gift would lapse rather than pass to the brother's children.
An alternative beneficiary designation also supersedes the antilapse rule. If the will names a backup beneficiary ("to my brother, or if he does not survive me, to my sister"), the backup takes priority over the automatic substitute gift.
The statute also protects payors, such as banks or insurance companies, who make payments based on the original beneficiary designation before receiving written notice of an antilapse claim. This ensures that institutions are not penalized for following the document on file.
