my husband won his civil claims case against him,the person is now seeking the same claim in a different town is this legal?

It sounds like someone made a claim against your husband, sued him, and lost in court.  If so, there would have been a judgement entry dismissing the claims.  If the same person is suing your husband for the same claims in a different jurisdiction - they cannot do that because that matter has already been decided by a competent court.  Your husband should present the dismissal entry to the new court and ask that the case be dismissed on the grounds of "res judicata."
