Since the Welfare Reform and Pensions Act 1999 the courts have had the power to share pensions between a couple in divorce or dissolution settlements.
If you have recently separated from your partner who also has parental responsibility for the children, you may find your ex-partner refusing to allow you to take the children on holiday outside of the jurisdiction of England and Wales. In such situations you will require permission from the Court to take your children on holiday otherwise the travel may be considered child abduction.
