A method for obtaining boundary conditions for magnetization in ferromagnetic structures with an inhomogeneous ground state - a relativistic and exchange spiral caused by the presence of competing exchange interactions - is proposed in this paper within the framework of a lattice model with a subsequent passage to the limit to the continuum. It is shown that such conditions are the equations of the dynamics of the magnetization of those boundary spins in which the symmetry is broken in comparison with the internal ones. Keywords: scattering of exchange spin waves, exchange spiral, relativistic spiral, boundary conditions for magnetization.
