A statement under subdivision (1) must include the name and address of the person to whom the property is conveyed or transferred.

(d) If a depositor fails to satisfy costs and fees within sixty (60) days after the termination of the depositor's use or ownership of the property served, the depositor forfeits the depositor's deposit and all accrued interest.  The forfeited amount shall be applied to the depositor's outstanding fees.  Any excess that remains due after application of the forfeiture may be collected in the manner prescribed by section 31 or 32 of this chapter.

(e) A deposit may be used to satisfy all or part of any judgment awarded the municipality under section 31 of this chapter.
