We have been split 2 years, the only reason he would apply for PR would be to spite me and I doubt under the circumstances that he would get it!!
I just found this on CAB website...
Changing a child?s name
A child?s name can be changed at any time, provided it is not to deceive or defraud another person. There is no legal procedure which must be followed in order to change a child?s name, providing all the people who need to give their consent have done so. The parent simply starts using the new name. A child?s forename or surname can be changed, names can be added or rearranged.
Although there is no legal way to change a child?s name, you may need evidence that a child?s name has been changed (see under heading Evidence of change of name ). However, the details on a child?s birth certificate cannot be changed, except in limited circumstances.
Changing details on a child?s birth certificate can be complicated. If you wish to do so you should consult an experienced adviser, for example, at a Citizens Advice Bureau. To search for details of your nearest CAB, including those that can give advice by email, click on nearest CAB .
If you are a child or young person under 16 your consent does not have to be given for your name to be changed. However, if you object to your name being changed you can apply for a court order to prevent the change, provided the court is satisfied that you have sufficient understanding of what is involved.
As a child or young person under 16 you cannot change your surname without your parent?s consent.
Once a child?s name has been changed it can be used for all purposes, such as starting school and registering with a GP. However, evidence may be required (see under heading Evidence of change of name ).
Who can change a child?s name
Where only one parent or person has parental responsibility for a child, that person can lawfully change the child?s name. Where two or more people have parental responsibility for the child, one of them can lawfully change the child?s name if all the others agree. Such agreements do not need to be in writing.
If there is a residence order in force, a child?s name cannot be changed without the written agreement of anyone else who has parental responsibility or the permission of the court.
For more information on residence orders, see Relationship breakdown and children in Ending a relationship .
This means that where the parents are or have been married, neither can change the child?s name without the consent of the other parent. If the parents have not been married, the mother can change the child?s name without the father?s consent unless he has acquired parental responsibility through agreement or by a court order.
For more information about parental responsibility, see Cohabitation and marriage: legal differences .
