Legal Question in Family Law in New York

Not sure what you mean by "file an injunction." If you mean you wish to go to the Family Court in your area and file a family offense petition and secure an order of protection, there is no hard and fast deadline for time after the abuse stops, but common sense dictates that if a lot of time passes, you have no good reason to feel threatened and thus will have a hard time justifying your request for an order of protection. You should also be aware that not all "verbal abuse" would constitute a family offense under law.
