We develop a general approach to the problem of the propagation dynamics of higher-order multipole spatial solitons in nonlocal nonlinear media. By introducing the generalized Hermite-Laguerre-Gaussian ansatz similar to the corresponding linear modes, we construct nonlocal solitons by means of the variational approach and then find them numerically as stationary states. We then study the example of a tripole-like structure with nonzero angular momentum and investigate the stable propagation of
