Can post-dated cheques be revoked?

So I don't quite understand all of the answer, thank you for your time.

It means a cheque must be honoured. If you gave it means you owe the payment. It does not require an agreement to be signed.

Please approach the owner to accept your request to return the balance cheque.

Thank you for that. What happens if he doesn't return the cheques?

Criminal case (jail+fine+travel ban) and Civil case.

But you said the cheque is like an agreement which seems to me like it's a bound agreement? So you are saying that we could get out of this?

Thank you for all your time we really appreciate it.

When I said a cheque is an agreement it means you have to fulfil your obligation ie to honour it. An agreement is made to do something in return for something.

The only way to get out is to talk to the owner and explain your problem. If he does not listen to you then borrow and see to that the cheque does not bounce.

You said if he doesn't return the cheques then this can happen - 'Criminal case (jail+fine+travel ban) and Civil case'. How does this happen then?
