Contract law for buying real estate

[Shashank Gokhale]

Im in Texas, but this pertains to any state.  Is it necessary to use the real estate contract that the state provides or can you make up your own contract?  

As long as both parties agree to and sign a contract, then do the provisions in that contract decide whether the contract is fully executed properly or does the state's contract override some of the provisions in the contract to which both parties have agreed and signed?  So if I choose not to have an option period for the purchase of a property but instead choose to have an inspection period, and I dont pay any fee for that period, then even though the state contract says that a fee is needed for an option period, does the state say that the inspection period I got is the same as as an option period, and since no fee was paid, the inspection period was not a part of the contract?
