Bismihi ta'ala

If the Shar'i talaq was conducted in the correct way, with all the fiqhi conditions met, then the wife's 'iddah period will be 3 menstrual cycles.

After this, the wife will no longer be mahram to the husband.

Of course, this would  alsodepend on what type of divorce was perfomed. If it is a Ba'in (irrevocable) divorce, then the wife becomes non-mahram once the divorce is conducted.

And Allah knows best.
