The text messages from your wife can be introduced at the hearing as evidence against you but I doubt they will be the sole factor considered by the judge in making a custody determination. Your wife should testify at the hearing explaining the circumstances and admitting that she acted inappropriately and explaining how she would handle it if the situation arose again. Unless your wife is physically assaulting the children then I would not anticipate an order prohibiting the children from...
If you have shared legal custody then you must let him know what is going on. Preferably, he should agree to the changes. However, if he does not participate and if you make the decision, his only recourse will be to file a petition for contempt for your violation of the shared legal custody provision.
The relocation provisions contained in the Custody Act are very specific. You must comply with them or else you cannot seek a relocation. I highly recommend that you review with an experienced attorney the requirements of the Custody Act relating to relocation and the specific facts of your case prior to taking any action.
Try to submit in York. The case will not be dismissed but rather it will be transferred to either Adams or the other county if York decides not to keep it due to no one living there. If either of you lived in York when it was filed it should remain there. Also, it should remain there since no one objected to it being there.
Once the divorce was bifurcated, were the economic claims ever resolved? If not, you'd better get a master's hearing scheduled to address these things. If they were resolved by a divorce master or a marital settlement agreement, then this should have been included and if she is violating an order or agreement, you can file a petition enforce the order or agreement.
Some attorneys work differently than others, but if you are concerned that your attorney does not have all of the facts I would recommend providing your attorney with a timeline of events relating to the case plus any additional information you have that you think would be helpful to the attorney preparing the case. An attorney can never have too much information, but often does not have enough. In other words, it's better to provide too much than too little information to your attorney. If...
I is always preferable to have an attorney with you even if your case is strong because there are procedural pitfalls that you could hit which would result in a less favorable result that you could have had if you had the benefit of a seasoned attorney explaining the process to you. At the very least you should seek a consultation with an experienced attorney in your jurisdiction.
You need to be careful when dealing with foreign travel as some countries, such as Japan, do not have reciprocity with the United States and if your ex would not return from the country then you would not have any method of getting them back. If this is a concern, you would want to petition the court to require your ex to post a bond prior to traveling out of the country or otherwise put safeguards in the custody order to prevent any issues related to foreign travel and passports.
If you do not agree then you will need to file a petition. School is not mandatory until age 8 and in York County the court has taken the position that the selection of school district issue does not need to be addressed until the child is about to begin first grade, not Kindergarten. Therefore, the time to file would be in the spring prior to the fall semester for first grade.
As long as you have the decree to reference, it is basically the same form entitled "Notice of Intention to Retake Prior Surname".
