A corporate Seal is a protection against fraudulent activity. It has legal value (by default defends) in case anybody creates false docs or makes false loans in your company name. It’s highly recommended if your company has frequent transactions or provides receipts and invoices. It’s also needed if you go for a loan, mortgage, employment contract, service contract or any sub-contract.
