I would first consult with a local attorney. Because he will not consent you will need to terminate his rights based on a theory of abandonment. There is a provision in the Florida Statute that makes it easier to terminate based on his removal from the life of the child or children for certain criminal behavior; he is serving a minimum of 15 years so that will efectively negate any involvement while the children are still children. Having said that men who are in prison tend to write to the Judge because they have nothing better to do. Although I think that you will ultimately prevail it may be more difficult than first meets the eye. Best of luck to you.

The easiest way is a stepparent adoption wherein the biological father consents to the adoption, otherwise, you will have to formally terminate his parental rights and then proceed with an adoption.
I would speak with local counsel regarding you case.

I agree with counsel above that a stepparent adoption is easier. However if your ex will not provide consent then you need to seek counsel to help you terminate his parental rights so that your new husband can adopt your children.
