Weak ferromagnetism in ${mathrm{Fe}}_{1ensuremath{-}x}{mathrm{Co}}_{x}{mathrm{Sb}}_{2}$ is studied by magnetization and M"ossbauer measurements. A small spontaneous magnetic moment of the order of $ensuremath{sim}{10}^{ensuremath{-}3}{ensuremath{mu}}_{B}$ appears along the $stackrel{ifmmode hat{}else ^{}fi{}}{b}$ axis for $0.2ensuremath{le}xensuremath{le}0.4$. Based on a structural analysis, we argue against extrinsic sources of weak ferromagnetism. We discuss our results in the framework of the nearly magnetic electronic structure of the parent compound ${mathrm{FeSb}}_{2}$.
