probably not. have your husband take all the court papers about this child, and a copy of the original birth certificate to a lawyer fast. after the lawyer reviews these papers and talks with your husband, the lawyer can give advice on what to do.
Why have you and your husband waited 9 years to do anything about it? has a DNA test ever been done as far as you know? Was your husband's ex already divorce from your current husband before the child was born and already remarried to her new husband? You need to consult with an lawyer in your local area ASAP
