Dear User,
Based on information shared through your post our suggestion is:
In line with the terms and conditions of your Agreement invoke the relevant clause and OFFER to pay the balance 20% of sale consideration and request him to complete the formalities. (DO NOT PAY - JUST OFFER - IT IS A LEGAL REQUIREMENT TO SHOW YOUR BONAFIEDS. FURTHER HAVE PROOF OF SAID 20% SALE CONSIDERATION IN YOUR HAND ON EVEN DATE.)
Caution:
You should perform your part of contract of paying the entire sale consideration as agreed.
If you show your readiness and willingness to perform your part of contractual obligation i.e., inform him about the same before the expiry of your agreed term of three months.
Keep a record of postal receipt, acknowledgement and a copy of your request.
Send your request through RPAD & A STANDARD COURIER SERVICE.
PS: If you perform your aforesaid contractual obligations, upon expiry of agreed term, you can approach court of law for addressing your grievance.
With regard to your second query, if at the time of your Agreement your proposed seller is the owner then subsequent transactions / changes will attract criminal proceedings. Therefore, no need to panic.
As far as division and giving of land to his son is concerned, if it is done through proper channel i.e, Registration etc., he shall be liable to answer both civil and criminal proceedings by you. Now onwards, keep record of all the material proofs in documentary form ……….
Good Luck.
