if you are refering to the child's home state/county, then the answer is yes. for example, you cannot move the child to another county, or state and petition that county court, or state court for custody rights.
My child's father left state for two year can he take my child for a week if i say no?
Easy. Just petition court for exactly that. A change of venue...its determined by where the child lives.
No, you cannot move a child out of state if you have joint custody.
The guidelines are basically the same in every state but obviously there are a few minor differences. Joint custody consists of Primary Custody & Secondary Custody. The parent with primary custody is who the child lives with & the other parent has secondary custody. Depending on the age of the child & the state in which they reside, the court may let them determine where they choose to live. Or if both parents agree on the child's decision then the child can live with either parent.
If the child lives with you for six months, you can register jurisdiction in your state, if it's not already there, than file for a change of custody due to long term possession. It's not likely she will be ordered to pay child support, only 7 out of 1000 mothers do. To learn what to do, check Dads House below.
You may since sole custody implies the child lives with that parent 100% of the time. With joint custody the child may dwell with the other parent for part of the time or with one parent all of the time with visitations for the other parent. It depends on the details and the state child support guidelines.
Permission from the other parent. Yes if you are in leagule custody of the child at the time
How would he do that without being in possession?
Read the Uniform Child Custody Jurisdiction And Enforcement Act (UCCJEA). Most states have adopted it.
It is highly unlikely that a grandmother would be given custody just because the father lives out of state. If there are other factors such as abuse by the father then, possibly, but not certainly. The court would look at the case carefully and decide what is best for the child
Why is the child in state custody?
