ExH emigrating and is NC with DS, by his choice. Where do I stand with parental responsibility?

[Blueuggboots]

ExH has PR as we were married when DS was born.

Split up last year and he has been NC for last 3 months and this is unlikely to change.

What happens with PR? Do I still have to consult exH over decisions even when he's made it clear he's not interested in having a relationship with his son?

I don't know where he lives, and I know he's planning on emigrating in the next few years. Help please!

I thought I could take him abroad for 28 days at a time without permission?

Do you already have a Residence Order in your favour? If so you can take the child abroad for up to 28 days and do not require consent from those with PR to go abroad on holiday.

A Residence Order or a new Child Arrangement Order determining where a child lives is only appropriate if there is a dispute about where a child lives. Otherwise if you have made all reasonable attempts to contact your ex to obtain consent for important issues such as holidays abroad or changing schools you need to apply for a Specific Issue Order to ask the court to grant permission.

I'm just researching at the moment so I know where I stand.
My exH hasn't contacted us for months but I don't want to end up in a situation that's difficult because I've not been fully informed.
