Legal Experts: I got a legal notice (cooked up) from a lawyer on behalf of his client (whom i do not know nor met him till date) stating that i have executed a Non Possessory agreement of sale 18 months back for an agriculture land (belongs to my joint family property and no legal document exist other than agriculture passbook on my name) stating that i proposed to sell and they paid an advance of 90% amount (stating that in presence of elders) that time and i was avoiding to register though his client is willing to register by paying balance 10% amount. He also states if the amount is not paid, 24% p. a. payable as interest till registration of sale deed. Now he sent this notice stating his client is ready to pay balance 10% to execute the suit otherwise he is going to file suit for a decree. Pl note that all above are incorrect and i never entered any agreement nor received any money nor went to that town to sell any property. Pl also note this is as reaction to other petition i filed as Partition suit for rightful share on our joint family ancestral properties and i assume this is revenge to create litigation through one of the defendant binami party (through above client). Please guide me what should be my response to that notice and is this valid in courts of law for such fraudulent or dummy/artificial notice without any basis or facts.
