 Where is the document? Is it a receipt/pronote/agreement? Does it say that the money was given by cheque? 22 lakhs can't be paid in cash. You can complain to the Income Tax Department also that the party had no capacity to make such a large payment and is not reflected in its books of account.

First of all, you father can lodge a police complaint giving all the details. Delaying matters would not be in your interest.

A lady assessee's income tax return was verified by her husband, forging her signature and got the refund also. She has been filing returns for the last 25 years. The Income Tax Department, when complained about it, is still hatching eggs - verifying the signatures. Only three years have passed since the complaint was made. 

Ruchika's case - 19 years. Verification of signature 57 years.
