Question on a Purchase agreement

[Jason Jay]

So I have this contract and live in California.  I have a property that is an awesome deal in Missouri.  It's a 3 bedroom, 2 bath house and  the blank contract I have has this 

"CONTRACT FOR THE SALE & PURCHASE OF REAL ESTATE

PARTIES: Owner Of Record"  

For the parties do I keep it as is or put the persons name in there?

What is the "Legal Description"?

For this part what is the typical time frame?

"ACCEPTANCE: This instrument will become a binding contract when accepted by the Seller and signed

by both Buyer and Seller. If it is not accepted and signed by the Seller prior to:_____________________,

this contract shall be void."

Any help would be greatly appreciated.
