Abstract : Seyferts and LINERs are radio-quiet AGN typically found in spiral galaxies with their spectra showing high-ionisation and low-ionisation emission lines (Peterson 1997). Recent sensitive radio surveys of Seyfert & LINER galaxies have detected kiloparsec-scale radio outflows (KSRs; Gallimore et al. 2006) in >40% of these galaxies. The drivers of KSRs in Seyferts/LINERs is a matter of ongoing debate with the primary contenders being AGN outflows and starburst superwinds. One of the clearest ways to understand the true origin of radio emission in Seyferts/LINERs is to follow the polarized synchrotron radio outflows from parsec to sub-kpc and to kpc-scales. I will present results from a polarization-sensitive VLA & uGMRT/e-MERLIN study of the Seyfert and LINER galaxies belonging to the CfA+12micron sample and discuss their properties from sub-kpc to the kpc scales, the magnetic field structures in their outflows and the depolarizing effects of their environment, and the interaction between the outflows and the surrounding media in order to understand the `AGN feedback' phenomena in low-luminosity-AGNs.
