Agreement

Is agreement mention the date on which agreement was executed between the parties? If there is date of execution then the same shall be treated as date of excution otherwise it would be last date when the agreement was finally signed by either party. You may consult Indian Contract Act. 

the agreement comes into force from  date of execution.

if that's not mentioned

Time is the essence of any agreement or contract.. If no date of execution,then Date of final signature of either parties.

okay , thanks a lot, if possible can you provide any link, judgement or can guide where will i find the source, anything will help.
