Is it permitted to have semen removed from your husband after he has died in order to have children from him later on?
If the husband did not agree to have his semen removed after his death in order for his wife to bear his children, then it is forbidden to do so and there is no halakhic dispensation.
However, if the husband did request such a procedure to be done after his death, the matter depends on a difference of opinion among posqim. Therefore, the counsel of a qualified rav poseq must be sought.
