I wt to inquire about the rights of wife and kids

Thanks for joining and trusting us, much appreciated!

We would like to inform you that  one of your right in marriage is that your husband shall maintain you, so you shall restrict him to pay for your expenses.

I do not know the type of lawsuit filed between you to determine the rest of the rights, but if the lawsuit is a divorce lawsuit and proved the husband's mistake, you may get from him your rights resulting from the divorce which are Idda alimony, Matta'a alimony, and the dowry.
According to the given information, I would like to inform you that you have to raise a claim for the expense of the father of the children on his address in Japan.
You have to ask the father to pay the aliment to the children from the date of his abstention from spending on him according to his income and property.
Then they will communicate with the competent authorities in Japan and inquire about your husband's income and the ruling that your husband will be obliged to pay for his children according to the amount of his income.
You can also raise a claim for marital expenses to your husband by committing him through the lawsuit by paying the amount of aliment. You are entitled to get aliment and you can raise the claims in one lawsuit, raising the claim of child aliment and spending as a wife in one legal case and get one judge and it will be implemented diplomatically on the husband\ father.
