A system of two plane charged bilayers in electrolyte solution was considered with regard to possible redistribution of the charged lipids under the effect of the electric field. Force and energy conditioned by electric and van der Waals interaction were analysed. Two possible mechanisms of charge redistribution were proposed and analysed: the lateral one and by the "flip-flop" type. The results for these redistribution types were compared with those for fixed charge density. Relationships between inner field on the membrane surface potential differences resulting forces and energies and the distance between the membranes and the effect of charge redistribution were analysed. The redistribution of the surface charge was shown to weaken the pushing part of the membranes and to decrease the intermembrane field, which promotes the adhesion without damaging the membrane structure.
