I present models of disk evolution around young binary stars. I show that the primary factor in determining circumbinary disk lifetimes is the rate of disk photoevaporation. I also find that photoevaporative clearing leaves a signature on the distribution of circumbinary disk lifetimes, with a sharp increase in disk lifetimes for binary separations a less than or similar to 0.3-1 AU. Observations of young binary stars can therefore be used to test models of disk evolution, and I show that current data set a strong upper limit to the rate of on-going photoevaporation (< 10(-9) M-circle dot yr(-1)). Finally I discuss the implications of these results for planet formation and suggest that circumbinary planets around close (a less than or similar to 1 AU) binaries should be relatively common.
