Types of Devises
A specific devise names a particular asset ("my Toyota Tacoma"). A general devise gives a stated dollar amount. A demonstrative devise names a source for the gift but is not lost if the source disappears. A residuary devise covers everything left over.
When a Devise Fails
If a specifically devised item is no longer in the estate, the gift may be adeemed under A.R.S. 14-2606. If a beneficiary dies before the testator, the gift may pass to that beneficiary's descendants under Arizona's antilapse statute, or fall into the residue if antilapse does not apply.
