I am a Solicitor and will assist you.
If you hold parental responsibility for your children ( by virtue of either being married to the mother when the children were born or being named on their birth certificate) then your permission is required to remove the children from the Jurisdiction.
If you agree to the relocation then a court order is not required. It is better for permission to be given in writing but verbal permission will suffice.
If you dont agree removal then you need to be making an urgent application to court for the children to be returned.
If she doesnt provide an address then you may not want to provide your permission. Thi may also be the position if your contact cannot be agreed.
To make an application to court you complete the C100 Form and take it to your local family court and ask to be seen by a Judge asap. The court fee is £215.

In relation to the matrimonial finances - if there is already an order in respect of the same then this is a separate issue. Any court order needs to be complied with. If there is no such order the you need to be going through the process of full and frank disclosure and discussions about division to either reach an ageement that can be embodied in a consent order for a Judge to approve or if agreement cannot be reached then applying to court for a financial order so that the Judge can make the decision.
