When Kansas prejudgment interest applies
Prejudgment interest is available only on LIQUIDATED claims — where both the amount due and the date it became due are fixed and certain, or definitely ascertainable by mathematical computation. It is generally BARRED on unliquidated claims (amount not fixed/ascertainable). A good-faith dispute over liability does not by itself defeat prejudgment interest once the claim is liquidated.
When it starts accruing
Accrues from the date the claim became due / the amount became liquidated (the day the account is liquidated and the balance ascertained; for periodic obligations, from each date the respective amount became due), running until the date of judgment.
