My ex-husband is deploying in a few months. His new wife is wanting to have his parenting time. Do I have to let him go with her? She is into drugs has a record a mile long, can't keep a job, and most likley will live with friends while he gone. What do I do?

First what does the child visitation order say ?

Normally he has the visits, not someone else, plus what does the order even say about who picks the child up.

Now in cases where there are 1/2 brothers and sisters, we recommend having somme contact since they are family also.
