Can parents sign off to be emancipated at 15 if the parents a drunk?

They can sign for emancipation if they are alcoholics, yes, but the states that have the option of emancipation requires the teen to be at least 16. Then it's up to the judge to decide and if you have fulfilled all the requirements. If a minor have a alcoholic parent and need help they will have to turn to the Children Protective Service. Emancipation is not the first choice.
