Official Rules for Alphabetical Filing

1. **Rule 1 (Unit Order for Individual Names):** Individual names are indexed in this order: **Last Name (Unit 1), First Name (Unit 2), Middle Name or Initial (Unit 3)**.

- *Example:* Maria Santos Cruz $\rightarrow$ **Cruz, Maria, Santos**

2. **Rule 2 (Prefixes):** Last name prefixes such as *De, Del, De la, Von, Van, Mac, Mc* are considered part of the last name, not separate units. - *Example:* Juan de la Cruz $\rightarrow$ **De la Cruz, Juan**

3. **Rule 3 (Hyphenated Names):** Hyphenated last names are treated as a SINGLE filing unit. - *Example:* Ana Smith-Santos $\rightarrow$ **Smithsantos, Ana**

4. **Rule 4 (Titles and Seniorities):** Seniority terms like *Jr., Sr., III, IV* or titles like *Dr., Prof., Atty.* are placed in the LAST unit. - *Example:* Dr. Jose P. Rizal Jr. $\rightarrow$ **Rizal, Jose, P., Dr., Jr.**
