Third-Party Security Agreement Template for the United States

A Third Party Security Agreement is a specialized legal document that allows lenders to secure loans with collateral owned by someone other than the borrower. Under U.S. law, these agreements are governed by UCC Article 9 and create enforceable security interests in assets belonging to third parties who agree to support another entity's debt obligations.

When do you need this document?

You need a Third Party Security Agreement when a lender requires additional collateral beyond what the primary borrower can provide. This commonly occurs in corporate group financing where a parent company secures a subsidiary's loan with corporate assets, or in family business arrangements where one family member pledges personal or business assets to secure another's borrowing. The agreement is also essential in situations where related entities cross-guarantee each other's obligations, or when investors provide collateral to secure portfolio company debt. Without this formal agreement, lenders cannot legally claim rights to third-party assets, even with verbal assurances.

Key legal considerations

The agreement must clearly identify all parties: the secured party (lender), primary debtor (borrower), and third-party security provider. Critical provisions include a precise description of the collateral, formal grant of security interest language that complies with UCC Article 9, and comprehensive representations about the security provider's ownership rights and authority to pledge the assets. You must address perfection requirements, which may involve filing UCC-1 financing statements or taking possession of certain collateral types. The agreement should include detailed covenants about maintaining, insuring, and protecting the collateral, plus specific enforcement mechanisms if the primary debt goes into default. Consider including provisions for partial releases as the debt is paid down and cross-default triggers that activate the security interest.

Legal requirements in United States

Under UCC Article 9, the security interest must be properly created through an authenticated security agreement that adequately describes the collateral. Perfection typically requires filing a UCC-1 financing statement in the appropriate state filing office, though some collateral types like deposit accounts may require different perfection methods. The agreement must comply with attachment requirements: the debtor must have rights in the collateral, value must be given, and the security agreement must be properly executed. Federal securities laws may apply if the collateral includes investment securities or similar instruments. Bankruptcy Code provisions affect enforcement rights, so consider including adequate protection mechanisms. State-specific variations in UCC adoption may affect certain provisions, and you should ensure compliance with local filing requirements and any applicable consumer protection laws if individuals are involved as security providers.
