We design and analyze a posteriori error estimators for the Stokes systemwith singular sources in suitable $\mathbf{W}^{1,p}\times \mathrm{L}^p$ spaces.We consider classical low-order inf-sup stable and stabilized finite elementdiscretizations. We prove, in two and three dimensional Lipschitz, but notnecessarily convex polytopal domains, that the devised error estimators arereliable and locally efficient. On the basis of the devised error estimators,we design a simple adaptive strategy that yields optimal experimental rates ofconvergence for the numerical examples that we perform.
