  The realization of an effective spin (Jeff) 1/2 state at low temperatures
offers a platform to study the enthralling physics behind the disordered states
in certain systems. Here, we report the signatures of magnetic ground state
associated with Jeff = 1/2 in CeVO4. Our studies confirm the absence of any
ordering or freezing down to 1.8 K. In the low temperature region, the
Curie-Weiss fit of the inverse DC susceptibility indicate towards the presence
of antiferromagnetic correlations among the Ce3+ spins. The calculated value of
effective moment (~1.16 {\mu}_B) corresponds to J = 1/2 with gJ ~ 1.20.
Further, the field dependent magnetization curve at 2 K follows a behaviour
corresponding to J = 1/2 Brillouin function with gJ ~ 1.13. Magnetic field
dependent heat capacity fits very well with two-level Schottky scheme. Our
investigations suggest that CeVO4 can be a promising candidate to realise Jeff
= 1/2 properties among 3D spin systems
