A collateral warranty is a legal agreement that allows a third party — such as a funder, purchaser or tenant — to rely on the obligations of a contractor or consultant involved in a construction project.
It extends contractual responsibility beyond the original agreement, providing additional parties with protection if defects or issues arise.
Why Collateral Warranties Are Used
- Providing funders with security over their investment
- Supporting forward sales and property transactions
- Allowing tenants to rely on construction quality
- Reducing overall development risk
When You Need a Collateral Warranty
- When securing development or project funding
- When selling or leasing property
- Where third-party protection is required
- On most commercially funded developments
How Collateral Warranties Work
- Issued by contractors, subcontractors or consultants
- Extend duty of care to named third parties
- Typically executed as a deed
- Often assignable to future owners or funders
Why It Matters for Developers
Collateral warranties help ensure developments are fundable, tradable and commercially viable. Without them, third parties may lack direct legal recourse if issues arise.
For first‑time developers, understanding warranties is essential to avoiding delays and protecting project value.
