Dear Deepthi,
C.L. is a liability the payment of which will arise in future.
For example say the guarantee given to bank in case of default by co.. or any case say Sales Tax case is pending before the court, the payment of which depends on the default by Co. or outcome of court verdict respectively.
C.L. is not included in B.Sheet. & it is always shown by note.
For further reference , refer any audit book.
Regards
Ram
