We present two confirmed wide separation L-dwarf common proper motion companions to nearby stars and one candidate identified from the Two Micron All Sky Survey .
Spectral types from optical spectroscopy are L0 V , L2.5 V , and L8 V. Near-infrared low resolution spectra of the companions are provided as well as a grid of known objects spanning M6 V – T dwarfs to support spectral type assignment for these and future L-dwarfs in the z ’ JHK bands .
Using published measurements , we estimate ages of the companions from physical properties of the primaries .
These crude ages allow us to estimate companion masses using theoretical low-mass star and brown dwarf evolutionary models .
The new L-dwarfs in this paper bring the number of known wide-binary ( \Delta \geq 100 AU ) L-dwarf companions of nearby stars to nine .
One of the L-dwarfs is a wide separation companion to the F7 IV-V + extrasolar planet system HD89744Ab .
