Codicil

Will

Life interest

The right to use or benefit from an asset during your lifetime, after which it passes to someone else.

Nonprobate transfer

An asset that passes directly to a named beneficiary without going through probate — such as life insurance or pension nominations.

Schema

A structured template that defines what information an INHERIT document can contain and what format it must be in.
