the right to divorce is in islam but it has conditions. one of them is that if the husband doesn't gives the woman the home's money for 6 months, the woman can take divorce.
but it's better to have the family build than to give it up.
i don't know the complete rules for divorce but there are sources, in Judiciary system of iran, you can see the laws in there.
Is Islam in Iran have another copy of the Koran
It's the same Koran
The same teachings
Only there is a difference in some of the teachings
In the issue of divorce all Islamic schools
Have the same source
Divorce right not owned by women in Islam
This is a clear distinction
Women have the right to differentiate
If the man refused to divorce
There are Mkhalah
The mean Almkhalah
The woman waives all rights
Then the judicial differentiate them
The divorce arbitrary right hand only man in the Islamic sharia law
