Jurisdiction - how is it decided?

If a couple are married in one county, divorced in the same county, do all custody issues have to be heard in the same county?

If a husband has moved into another county, can he begin an action in that county, or does it have to be in the county the child is living in or where all other actions have been heard in court?

Thanks and have a good holiday weekend.

Jurisdiction for custody is based on the state, and it is not tied to where the parties were married or divorced. A person can file for custody in his or her county of residence, but the other party may have an argument to change venue depending upon where the child resides the majority of the time, goes to school, etc.
