There's a fashion battle brewing in the courts between designers Angelica Cota and L'Wren Scott, and we've got the docs right here on RadarOnline.com.

Cota, who designs the label LuLA, is filing suit against fashion designer Scott, who's just released her Lula handbag line. 

In her suit, Cota says Scott -- the Oscar dress designer who once dated Mick Jagger -- is using her patented name; Scott says Lula is named after her mother.
