D4E, thanks a lot for your detailed answer.
As far as I understood you, if agreement is possible I should go for it .
However, my wife feels that she can use the child 100 % and does not offer any agreement. Actually, it was clear for me that on the long run she can not have forever 100%. I always offered a dialog but was always very impolitely turned down.
She has full support of her family, and I think it makes her very happy, to play that role of the victim, etc.
I am offering her a parental plan 50%-50% on the paper. Because of the distance and in current situation I wont use even 1% . The point is that I might move to live in the same city in the future and I do not want to go through new case.
So my question is how likely is that I can get written court decision that I can have 50 % of time per year with my son ?
