Wife claiming 50% of husband's wealth after divorce

Q: My wife and I are experiencing marital problems. She is demanding a divorce from me. According to the legal system of the country where I reside, in the case of divorce, she has the right to claim 50% of my assets. I have not yet paid her mahr to her. She is now demanding 50% of my wealth as well as her unpaid mahr.

If she takes advantage of the legal system and takes me to court claiming 50% of my wealth, will this wealth be halaal for her according to Shariah and will I still have to give her the outstanding mahr?
