Mississippi Code Title 75. Regulation of Trade, Commerce and Investments § 75-9-305

A security interest in goods, instruments, money, negotiable documents, or chattel paper may be perfected by the secured party's taking possession of the collateral. A security interest in the right to proceeds of a written letter of credit may be perfected by the secured party's taking possession of the letter of credit. If such collateral other than goods covered by a negotiable document is held by a bailee, the secured party is deemed to have possession from the time the bailee receives notification of the secured party's interest. A security interest is perfected by possession from the time possession is taken without relation back and continues only so long as possession is retained, unless otherwise specified in this chapter. The security interest may be otherwise perfected as provided in this chapter before or after the period of possession by the secured party.
