How long do you have to be separated before divorce in Scotland?
You can divorce instantly if you can establish either your spouse has behaved unreasonably, and you cannot be expected to continue living with them or that your spouse has committed adultery. Otherwise, you would require waiting one or two years before applying for divorce.
If your children have been removed from their place of habitual residence (wrongful removal) you can take steps to get them back as long as the place they have been removed to is a signatory to the Convention. Likewise, if you have consented to a removal for a fixed period such as a holiday and your children are not returned ( wrongful retention) you can also take steps to have them returned.
You need to act quickly and make an application through the central authority (Scottish Government) I can help you with that and to find a good lawyer in the country the children have been taken.
