A work services contract was agreed between the service provider and customer through whatsapp discussion, negotiation and under certain condition based the quote provided by the service provider for interior works in a flat. However, the service provider, who represents the interior firm, not only delayed the project but also escalated the price even after finally agreed price.

I have been running a restaurant for last 4 years. Now I have decided to sell it for 14 Laks. The manager who was handling the restaurant showed interest in buying it. As he is not able to give the amount in lump sum we have agreed to pay 14 Lacs in 36 installments. As most of the terms are mutually agreed upon; I wanted to know what should we do to make it more legal and law binding document? How do we execute it for the mutual benefit?
