We present preliminary results of spectropolarimetric observations of several cataclysmic variables using the ISIS spectropolarimeter on the 4.2m William Hershell Telescope at La Palma. Our aim is to look for Zeeman signatures of magnetic fields in cataclysmic variables. This would provide a direct measurement of magnetic fields in the accretion flows of CVs. Our current dataset allows us to set upper limits to the presence of magnetic fields and constrain the field geometry in different types of cataclysmic variables.
