Is it permissible for a woman whose marriage has been annulled and whose waiting period has ended, but who has not received her divorce certificate due to the husband's appeal of the ruling, to become engaged and marry?

The preliminary divorce ruling does not sever the marital ties, because the enforcement of the ruling is suspended upon the acceptance of the appeal by the Court of Appeals. Its legal effects do not take effect until the final judgment is issued. Therefore, the woman remains legally a wife, and her iddah (definition) (waiting period) does not begin until the date the final divorce ruling is issued.
