husband of ten years has affair with two others what are my rights regards the children?

I'm sorry for the mess you find yourself in. I would do exactly as you plan. A legal separation will protect your assets and give you financial support that is legal and binding. You will get child and spousal support based on your income vs. his. Since you are not working outside the home, the calculation will be an easy one. You will need to petition this order formally with a court order through your attorney, but I can foresee no problems. You can get a restraining order restricting his movement with the children. He would be hard pressed to get custody of your children, unless he could prove you are unfit, which I sincerely doubt. California is a community property state, so I would stay in California, especially if you intend to file for divorce at some time in the future. Also FYI, his behavior has no bearing on any of this...California is also a no fault divorce state. I would highly recommend that you let both of the other parties know about each other.

The best to you.

You will be in favor in the court cause you're the mother, and what it sounds like you have the best interest for your children.

In Cali the main factors that determine custody are The best interests of the child, Which parent is more likely to encourage frequent visits with the other parent, Child's wishes, which are only considered if the child is of a certain age and maturity level (generally over age 12),History of domestic violence, and History of drug use.

You can also state the fact that he has cheated on you with a lady that wants to married him and also has another mistress on the side, that situation is not in the best interest of the children and shouldn't grow up with that. If his history is cheating and always having some one on the side then when will he have time for the kids if he has full custody. Tell the lawyer when you see him everything you know about him (the dirt). I hope you get full custody you deserve it.

Weather hes a cheater or not has no bearing on custody

Most likely if he requests joint custody unless there is a specific reason its not beneficial for the kids, the courts will grant him joint custody

If you spilt the kids, you wont get child support, you may get alimony from the divorce but that depends on a lot of things...

Best advice, consult an attorney.

His cheating has nothing to do with the custody issue. Custody will be based off of who can best support and care for the kids, along with other factors. If you want to know the specific rights of your state, contact a lawyer, they usually do a free phone consultation.

I understand you are in a tremendous amount of anxiety, but anyone on this forum can only GUESS. The lawyer is the one to seek advice from. There are many different factors that could affect your outcome.. you must have a fully informed lawyer to advice you.

You most likely knew he was a cheater when you married him. Cheating is in some people's blood. It happens fast and usually the other person thinks they can change the man/woman and so they marry knowing he is a cheat.

Get in there quick & get a decent settlement before those other b*tches spend his money.

I'd also be inclined to let lover no 1 know about lover no 2, anonymously of course

He's putting you in a tough spot. He is putting this all on you and taking no responsibility for his actions. You need a good aggressive attorney to advise you.
