Actually, the prosecution of your husband is an extra action that may force him to pay the damages occurred at yourself and children. I've given this advice in order to strengthen your arguments against him while directing your claims. The punishment of this crime is not a heavy one that can put him locked up in prison. He'll probably receive a monetary penalty if he has a clean criminal record. However, if you still prefer not to report him to the prosecutor's office, you can claim your rights in private law courts without getting in any criminal cases. Yet, you should bear it in mind that the prosecutor may automatically come into action during his trial of compensations.

You should file a case in Turkish courts in order to direct the claims regarding your and your children's rights from your husband. Furthermore, you can demand from the court to cancel his second marriage in order to exclude his second wife from his inheritance (provided that she wasn't aware of his first marriage while getting married).

You need the professional support of a Turkish lawyer for following up all these ways I've recommended.

Good luck,

King regards.
