Hi Mr. Vibhor,
You have high ethical and moral standards
Please refer to the Act regarding this. I am sure you wont find anything in the act as well as the rules.
You can just check if it contains all the requisites of a valid voucher like the Voucher Head i.e the Name of the College, its Registration information, complete address, Contact info is provided, whether the Voucher/Reciept contains a unique serial number, it displays name of the payer of tuition fees, on whose behalf it is paid, date of receipt, period for which it is paid,what is the nature of receipt (Donation, tuition fees ect)mode of receipt (Cash/cheque), Vaild signature of any authorised person ect, seal of the college ect
You can try contacting the college if you have the Phone No., or email them or write them a letter to check if the particular receipt no. & amount matches the clients.
But they can always deny you this info and choose not to disclose info about their books of accounts.
in that case how to check the validity?
Responsibility can only come with power. If we should not have responsibility.
If he truly knows how to con other people & forge receipts it would require the expertise of an investigator to go through the receipt, match it with other receipts issued by the same college, note any differences, handwriting analyist to test the signature, they also test the seal to note any differences, go through the college books of account to find out whether this serial number receipt exists and whether the client has truly paid it etc, whether the son really studies in engg college ect.
Thats my opinion. I also say opinions are like handwatches. Everyones shows a different time
