A buy and sell agreement, also known as a buyout agreement, is a legally binding agreement between co-owners of a business that governs the situation if a co-owner dies or is otherwise forced to leave the business, or chooses to leave the business.

In a cession in security, the cedent transfers its right of action to a debt owed to it, known as the principal debt, to the cessionary as security for the debt owed by the cedent to the cessionary, known as the secured debt. A right of action is the legal standing to collect the principal debt. The ownership in the right, however, remains vested in the cedent despite the cession.

A Commercial Lease Agreement is a lease agreement where a Landlord leases an immovable property (for example an office suite), to a Tenant. The Tenant uses the immovable property for business purposes.
