Does the divorced woman who sought the divorce have no rights or financial provisions from her ex-husband, according to Sharia, despite his provision for custody and the son's expenses?

If your husband divorces you without stipulating the forfeiture of any of your financial rights, then you are entitled to the full dowry, and maintenance for the iddah (definition) (waiting period) and for pleasure (mut'ah) according to some scholars. He is also obligated to provide you with housing if you do not have a residence, as long as you are the custodian of your child. However, if he agrees to divorce you on the condition of forfeiting some of your financial rights, then those rights are forfeited. As for mubara'ah (mutual divorce), it only forfeits what was agreed upon, according to the majority of scholars, whereas Abu Hanifa and Abu Yusuf hold that it forfeits all of her marital rights.
