Is there anything i can do about my husband threatning me?

My husband came to the park and yelled At my son and I and said he's gonna kill us. He also spit in my face kept hitting my car then took my IPhone and brooke it

Call your attorney and you get the kids

A death threat is illegal. He can go to jail. Next time record him saying that, then call the police

I may not be an expert.

But go to the police. They could get you into a witness protection program, and you and your son's names will be changed. No one but who you wish will know your new names, and your "husband" will have no way to find you.

You and your son will be safe.

Go to your police station and file a report on the incident against your husband. Then go to a women's shelter that accepts children. The police can probably suggest one or more locations.

Call the police, press charges, and have a restraining order against him.

He has committed a crime against you: assault. Assault is an act that creates an apprehension in another of an imminent, harmful, or offensive contact. The act consists of a threat of harm accompanied by an apparent, present ability to carry out the threat.
The spitting in your face may constutite the physical contact necessary for another charge: battery.

Go to the police and file a complaint. It will be especially helpful if you have witnesses who are willing to come forward on your behalf, so it doesn't turn into a "he said, she said" situation.

You should definitely call the police, if not then he could really hurt you. Just think of your safety with your child and call the police, they will deal with it. Or get a restraining order against him, i had to get a restraining order against my dad because he was a drug addict and always beat me and my mom.
