Property possession letter self declaration format

Hi,

I bought a property which will be ready for possession by March however I need to submit the proofs to my organisation in January. Company is ready to accept a self declaration possession letter as per the circular no 8/2012 of IT act.

Is there a format available that I can use to state that I will be receiving the possession letter by March? This will help in claiming the home loan interest for the current FY.
