You can create a Shareholder Agreement at any time but it's best to put one in place when you start your business. A Shareholder Agreement (SHA) is a contract entered into by the shareholders, ideally when the company is formed, that regulates their relationship and governs the management of the company.
Write the contract in six steps Start with a contract template. Open with the basic information. Describe in detail what you have agreed to. Include a description of how the contract will be ended. Write into the contract which laws apply and how disputes will be resolved. Include space for signatures.
To write a simple contract, title it clearly, identify all parties and specify terms (services or payments). Include an offer, acceptance, consideration, and intent. Add a signature and date for enforceability. Written contracts reduce disputes and offer better legal security than verbal ones.
