What is a process of a contract formation?

“An offer accepted is a contract” Viscount Stair   The acceptance of an offer must be communicated to the offeror and silence does not mean acceptance.   Most contracts can be created without the need for a written document, however, The Requirements of Writing (Scotland) Act 1995 changed the law by requiring a written document for certain contracts including property/land transactions, Testamentary writing, the creation of a trust.
