815 ILCS 170/1
That when any note, bond, bill or other instrument in writing is for the payment or delivery of personal property other than money, and no particular place is specified therein for such payment or delivery, the maker may tender such personal property on the day of payment or delivery, at the place where the obligee or payee resided or had his place of business at the time of the execution of the instrument. If such personal property is too ponderous to be easily moved, or the obligee or payee has not, at the time of the execution of such instrument, a known place of residence or business in the county where the maker resided, or had his place of business, then tender may be made at the place where the maker resided or had his place of business at the time of the execution of the instrument. A tender made in pursuance of this section shall be equally valid, in case the instrument is assigned, as if no assignment had been made.
