A life estate splits ownership of property across time: one person - the life tenant - owns and uses it for their lifetime, and at their death it passes automatically to the remainderman named in the deed. No probate on the transfer; the deed already decided it.
The catch is rigidity. Once a traditional life estate deed is recorded, the life tenant cannot sell, refinance, or change the plan without the remainderman's signature. Family circumstances change; this deed does not.
Arizona largely retired this tool by inventing a better one: the beneficiary deed delivers the same probate-free transfer while you keep complete control - sell, refinance, revoke, or rename at will. Life estates still appear in older plans and a few specialized strategies, but for most Arizona homeowners the beneficiary deed is the modern answer.
