Fabricated forging documents.

Dear Sir, I have received one notice from an advocate and stating that, I borrow 3.5 lakhs from his client on 10.10.19 on the security of the same I given to promissory note and I’m not willing to repay the borrowed amount and its interest. If not repay the entire amount with interest with in the 7 days of time after getting this notice, matter will go to the court. Also I noticed that, they filed a OS Suit against me and one property also attached with the suit. However, I have not seen this person past 17 years and no more telephonic conversation and any other financial / non-financial transactions with this person. With my inquiry, Also noticed that he is leaving another district and far away from me and he working as a carpenter. I’m not given any promissory note for anyone till my life. As my knowledge I have seen this person during the funeral ceremony of my husband only. Also note, attached property is not in our possession. Because attached property was by my husband title and after his demise, we couldn’t able to repay the home loan and due to this reason bank approach the court and the court had issued the sales certificate dated [deleted] in favor of the bank and currently bank has become the absolute owner of the property. I don’t know current situation how they attach the property. Attachment order is as listed below. “Issue summons to defendants for settlement of issues. For R/S – 30.7.20 IA 1/20 allowed IA 2/20 Petitioner has made out a prima facie case. Delay will defeat the purpose. Thus respondent is directed by an ad interim order either to furnish security for an amount of Rs. 350000/- or to show cause why such security shall not be furnished. Meanwhile, petition schedule property shall be under conditional attachment for the said amount. Issue U/N serve order for R/N 18.5.20” Please advise how to counter the above said forging documents. I can submit my bank account details to ensure the transactions. I’m a widow and jobless woman, staying at my son’s home.
