    (c) When a charge of theft of property exceeding a specified value is brought, the value of the property involved is an element of the offense to be resolved by the trier of fact as either exceeding or not exceeding the specified value.
    (d) Theft by lessee; permissive inference. The trier of fact may infer evidence that a person intends to deprive the owner permanently of the use or benefit of the property (1) if a lessee of the personal property of another fails to return it to the owner within 10 days after written demand from the owner for its return or (2) if a lessee of the personal property of another fails to return it to the owner within 24 hours after written demand from the owner for its return and the lessee had presented identification to the owner that contained a materially fictitious name, address, or telephone number. A notice in writing, given after the expiration of the leasing agreement, addressed and mailed, by registered mail, to the lessee at the address given by him and shown on the leasing agreement shall constitute proper demand.
    (e) Permissive inference; evidence of intent that a person obtains by deception control over property. The trier of fact may infer that a person "knowingly obtains by deception control over property of the owner" when he or she fails to return, within 45 days after written demand from the owner, the downpayment and any additional payments accepted under a promise, oral or in writing, to perform services for the owner for consideration of $3,000 or more, and the promisor knowingly without good cause failed to substantially perform pursuant to the agreement after taking a down payment of 10% or more of the agreed upon consideration. This provision shall not apply where the owner initiated the suspension of performance under the agreement, or where the promisor responds to the notice within the 45-day notice period. A notice in writing, addressed and mailed, by registered mail, to the promisor at the last known address of the promisor, shall constitute proper demand.
    (f) Offender's interest in the property.
        (1) It is no defense to a charge of theft of property
    
that the offender has an interest therein, when the owner also has an interest to which the offender is not entitled.
        (2) Where the property involved is that of the
    
offender's spouse, no prosecution for theft may be maintained unless the parties were not living together as man and wife and were living in separate abodes at the time of the alleged theft.
