Motivated by recent results on non-vanishing spatial curvature 1 we employ the holographic model of dark energy to investigate the validity of first and second laws of thermodynamics in non-flat (closed) universe enclosed by apparent horizon RA and the event horizon measured from the sphere of horizon named L. We show that for the apparent horizon the first and second laws of thermodynamics are respected while for L as the system’s IR cut-off first law is broken down and second law is respected for special range of deceleration parameter. It is also shown that at late-time universe L is equal to RA and the thermodynamic laws are hold, when the universe has non-vanishing curvature.
