Do you have any idea if your ex would be amenable to what you want to do? Because a consent decree for the modification would go a lot easier and cheaper.
This guy has been around almost forever if you are looking for experience.
My only advice is the more you and your ex can hash this out on your own the better. Once the courts get involved one or both of you may be very unhappy. Unless it's unavoidable, leaving these types of determination to a stranger (judge) can be dangerous.
When possible you want negotiation to be a collaboration, not a confrontation. My thoughts on negotiation is to try to figure out how to get the other person as much of what they want. The more you get them what they want, the more likely you will get what you want.
Understand that lawyers are in business for one thing. Be careful in mistaking a one hour chat for anything other than the person on the other side of the desk trying to see how much money you have in the bank and what their chances are of getting it all.I am looking to get my custody arrangement for my kids updated and would appreciate a good recommendation.
Thanks!
