Thank you for your letter
My name is ***** ***** I shall do my best to help you
Whilst your son is approaching the age at which his wishes will be decisive in the question of where he lives,
allowing or encouraging him to simply "walk out" in this way would backfire and could in fact ensure that for a further
couple of years he has to stay with his mother.
Your ex would have no difficulty in obtaining an immediate order for his return which could then be hard to overturn.
If this is what your son wants then you need to start discussing it with your ex next year - using Family mediation
and a Mediator trained to work with young people so that your son's views can be expressed to some one neutral.
If that fails then you need to make a formal application to the court - taking the correct approach gives you a much better chance of success
Please ask if you need further details
