Choose a name for your corporation. Your name must include some indication of corporate status, such as "Inc.", "corp", or "LLC". Most states maintain a search function on the website of the secretary of state that allows you to check your proposed corporate name against business names already in use. Use this search function to confirm that your proposed corporate name is unique.
Appoint directors and officers for your corporation. Most states require that you appoint more than one director, for example, California requires at least three. Appoint at least a president and secretary.
Complete the articles of incorporation. Some states offer a standardized form, while others require you to draft your own form. This document is usually only a page or two long and requires you to list the name of the corporation, the names of the directors, the name of the president and secretary, the corporation's principal place of business and its number of authorized shares.
Submit the articles of incorporation to the secretary of state of the state under whose laws you are incorporating, along with the statutory filing fee.
Draft corporate bylaws if your state requires them. Corporate bylaws function as a company constitution, setting out the rules by which the corporation is to be governed. Examples of provisions commonly found in corporate bylaws include how many shareholders' meetings must be held per year, what constitutes a quorum, and what corporate decisions shareholders, rather than directors, must decide. State law prevents you from inserting certain provisions in bylaws such as authorizing the board of directors to sell the assets of the corporation without shareholder approval. Some states do not require bylaws; no state requires you to file bylaws with any government agency.
Draft an asset transfer agreement in which your parent sells his assets to the corporation. To make the contract legally binding, the corporation must agree to pay at least a small amount for these assets. The purchase price need not be paid at the time of transfer -- payment can be delayed to a future date, and can be made from the assets that were originally transferred by your parent.
Issue share certificates to the family members to whom your parent wishes to transfer assets in proportion to the amount your parent wishes each member to receive.
