Thre is not nearly enough information in your question to provide any kind of analysis. Normally, jurisdicition is not something that can be "fought" -- it is a matter of it existing, or not. For a recap of the rules relating to child custody and support jurisdiction, see "The Basics of Family Law Jurisdiction," posted here. If it does not anwer all of your questions, speak with a family law specialist well versed in jurisdiction.
