Attachment & Perfection
of Security Interests

Master the UCC Article 9 framework for creating and protecting security interests in personal property: from attachment through perfection.

CPA Regulation (REG)

What Is a Security Interest?

A security interest is a legal claim or lien on personal property (collateral) given by a debtor to a creditor. It ensures that if the debtor defaults, the creditor can seize and sell the collateral to satisfy the debt.

Debtor
The person or entity that owes the obligation and provides collateral
Secured Party
The creditor or lender who holds the security interest in the collateral
Collateral
The personal property subject to the security interest

Why Security Interests Matter

Without a properly created and perfected security interest, a creditor is merely unsecured: they stand behind all secured creditors, bankruptcy trustees, and even later lien holders. Understanding this process is critical for the CPA exam.

Unsecured
No priority claim: paid last, often receives little or nothing in bankruptcy
Secured
Priority claim on specific collateral: first in line for repayment upon default

The Two-Step Framework

STEP 1 Attachment (Creates the interest) 1 Value given 2 Debtor has rights 3 Agreement/Possession STEP 2 Perfection (Establishes priority) A Filing (UCC-1) B Possession C Automatic / Control

The Three Requirements for Attachment

1
Value must be given by the secured party. This is usually a loan, line of credit, or binding commitment to extend credit. Past consideration counts.
2
The debtor must have rights in the collateral. The debtor must own the property or have the power to transfer rights in it at the time of attachment.
3
A security agreement must exist. Either an authenticated written agreement describing the collateral, OR the secured party takes possession or control of the collateral.

The Security Agreement in Detail

A valid security agreement must be authenticated (signed) by the debtor and must contain a description of the collateral sufficient to reasonably identify it. The description does not need to be exact: it can use UCC categories.

Authenticated
Signed by the debtor (electronic signatures accepted under UCC)
Description
Must reasonably identify the collateral by type, category, or specific listing
Alternative
No writing needed if secured party takes possession or control of the collateral

Methods of Perfection

Perfection Filing (UCC-1) Most common method Works for most collateral Possession Pledge of collateral Tangible goods, instruments Control / Auto Deposit accounts, investment property, PMSI Automatic Perfection: PMSI in Consumer Goods No filing or possession required: perfected upon attachment (Purchase Money Security Interest)

Filing a UCC-1 Financing Statement

Filing is the most common perfection method. A UCC-1 financing statement is filed with the appropriate state office (usually the Secretary of State). It gives public notice that the secured party claims an interest.

1
Debtor's name: Must be the debtor's exact legal name (individual or organization). Errors in the debtor's name are seriously misleading and can invalidate the filing.
2
Secured party's name: The name of the creditor or their representative.
3
Collateral description: Must indicate the collateral covered. A super-generic description like "all assets" IS sufficient here, unlike in the security agreement.

Attachment vs. Perfection

Attachment Perfection
Purpose Creates the security interest Establishes priority over third parties
Effective Against The debtor only Third parties, trustees in bankruptcy
Requirements Value + Agreement + Rights Attachment + Filing/Possession/Control
Timing When all 3 elements are met When attachment + perfection method are both complete
Without It No security interest exists Interest exists but is unperfected (low priority)

Purchase Money Security Interest (PMSI)

A PMSI arises when a creditor either sells goods on credit or lends money specifically to purchase the collateral. PMSIs receive special treatment under Article 9.

Consumer Goods
PMSI perfects automatically upon attachment: no filing required
Inventory
Must file before debtor takes possession and notify existing secured parties
Equipment
Must perfect within 20 days after debtor receives possession

Step-by-Step: Analyze a Security Interest

1
Identify the collateral type: Is it goods (consumer goods, equipment, inventory, farm products), accounts, instruments, chattel paper, or general intangibles?
2
Check attachment: Has value been given? Does the debtor have rights? Is there an authenticated agreement or possession?
3
Determine perfection method: Filing works for most collateral. Possession for tangible goods and instruments. Control for deposit accounts. Automatic for PMSI in consumer goods.
4
Assess priority: First to file or perfect wins. Check for PMSI super-priority. Buyers in the ordinary course of business take free of security interests.
5
Consider special rules: After-acquired property clauses, proceeds, future advances, and continuation statements.

Example 1: Basic Attachment

✓
Value given? Yes: the bank extended a $50,000 loan.
✓
Debtor has rights? Yes: Delta owns the equipment.
✓
Authenticated agreement? Yes: Delta signed a security agreement describing "all equipment."

Example 2: PMSI Auto-Perfection

1
Is this a PMSI? Yes: TechStore sold the laptop on credit and retained a security interest in the specific goods sold.
2
Collateral type? Consumer goods: Sarah purchased the laptop for personal use, not business.
3
Perfection method? Automatic: a PMSI in consumer goods is perfected upon attachment without filing.

Example 3: Priority Contest

Jan 1 Bank A files UCC-1 Feb 1 Bank B lends + files UCC-1 Mar 1 Bank A lends (attachment)

Common Mistakes to Avoid

✕ Confusing Attachment with Perfection
Attachment creates the interest between parties. Perfection gives priority over third parties. They are separate steps.
✕ "All Assets" in Security Agreement
"All assets" is NOT a sufficient description in a security agreement, which requires more specificity. However, it IS sufficient for a financing statement (UCC-1).
✕ Assuming PMSI Always Auto-Perfects
Auto-perfection applies only to PMSI in consumer goods. PMSI in inventory or equipment still requires filing.
