Laws in Qatar about trouble with wife and Govt help

When I had been to Dubai, I got to know that (for people from other countries)if there is a problem and the wife wants to get rid of marriage then if she lodges a complain then the legal help will be from the governament to such an extent that the husband will be called and will be made to pay for the maintanance. This will happen only if the women stays in that country and gets her rights. If he doesent pay he will b in life long trouble, he will not be ablle to go out of their country, his passport will be blocked etc etc. Whats the law in Qatar can anyone please tell me. And is it possible to get help without knowing any 1 here
