I have sole custody of my two children 7 and 3 and during my tour in the air force here at Osan AB South Korea my ex wife is trying to get my 7 year old daughter to go into court and choose my ex as to be her custodial parent and not me. She is in Monit North Dakota. Is she able to do this? At what age in North Dakota can a parent take a child to court and choose the parent to which they want to live with? My divorce papers say I am the sole parent and I also drew up paperwork that was signed by a judge that my ex would take care of them the last six months while I was gone, that thier residency would not change to North Dakota and that when I am done here in December that I am going to pick my two children up from her.
