N.J. Stat. Ann. § 44:1-114

Where a poor person who requires relief in a municipality or county in which he is a resident and inhabitant, has not gained a settlement in any municipality or county within this state, or in any other state, the overseer shall provide relief. If it is ascertained that the poor person has no legal settlement in the municipality, the overseer shall proceed to remove him to the place from which he came by whatever lawful proceedings may be necessary to that end with the aid of the officers as provided in this chapter, and the expense of his removal shall be borne by the municipality from which he is removed.
