An original guarantor is the party initially named in the development finance agreement as providing a guarantee at the point of funding inception. This individual or entity is contractually liable for the borrower’s obligations from the outset and is distinguished from any substitute or additional guarantors added later. In UK property development finance, original guarantors are central to lender risk assessments and are typically party to various security documents, including deed of guarantee and indemnity agreements, from day one.
In practice, the original guarantor remains a key reference point throughout the life of a development facility, particularly where lenders monitor covenant compliance, project performance and repayment risk. Even if funding arrangements are later restructured or additional security providers are introduced, the obligations of the original guarantor will depend on the specific terms of the finance and security documents. Within the wider framework of Parties and Roles, the concept helps distinguish the party that assumed liability at completion from any subsequent changes to the guarantee structure. It is also closely related to the broader role of a Guarantor, which may encompass both original and later-appointed parties in a property development transaction.
