Renames the crime from "failing to return" to "stealing" leased or rented property and expands the definition to include concealing property, selling or encumbering property without lessor consent, and failing to pay agreed lease charges.

Reduces the notice period for non-motor vehicle property from ten days to seven days after written demand sent by certified mail before criminal charges can be pursued.

Establishes 72-hour return requirement for motor vehicles after lease expiration; allows lessor to notify law enforcement to enter vehicle into stolen vehicle database and permits seizure by law enforcement officers.

Increases felony threshold from $500 to $1,000 in property value; offenses remain class A misdemeanor below $1,000 and become class C felony at $1,000 or more.

Applies provisions to all lease and rental agreements including lease-purchase and rent-to-own contracts; clarifies property ownership until lessor endorses sale to lessee.
