text: tri-care question? my finace' is in iraq and when he comes home we are getting married but here is my question... can he add my 18 month old daughter on to his tri-care even if she is not his child? he plans on adopting her but we have to be together for him to do that. he will be able to add her as a dependant  in deers  once you are married if you have full custody of her and she lives with you at least 75% of the time.  she does not need to be adopted to be added to deers and enrolled into tricare, but you do have to be married.
