Current with changes from the 2024 legislative session effective on or before 7/1/2024, from Acts 2,3, 6-535, and 580-647
When a term for the performance of an obligation is either fixed, or is clearly determinable by the circumstances, the obligor is put in default by the mere arrival of that term. In other cases, the obligor must be put in default by the obligee, but not before performance is due.
