👉 In real estate, a "caixa" or "caixa de garantia" refers to a clause in a property agreement that outlines the rights of one party (the obligor) against another party (the indemnitee) if the latter fails to perform under the agreement. This is typically used when there are specific conditions attached to the loan, such as the payment amount or interest rate, and the obligation holder wants to ensure they have a solid legal basis for their claim.
