Background: Male friend has an 11 year old son which has his surname. Him and the ex split when his son was 3 months. When he was one, the mum got with a new partner and has been with him ever since and has been married for 8 years. The son also has 2 siblings from his Mums side.
The mum has approached the father and asked can she double barrel sons surname, adding the married name. She gave the reasons as 4 members in the house have that name, she's been with the husband 10 years it's not like it's a new partner, she has stated the son has mentioned at times feeling left out and the fact my friend is marrying someone and that lady will end up with the same surname and the son is feeling a bit sad that he will share a name with a woman that isn't his family.
My friend has spoke with his son and son has confirmed the above. My friend refused the name change, and the woman is now saying she will take it through court and will more than likely get approved.
My friend has suggested she can double barrel it with her maiden name, which she refused on the grounds of that isn't her name, isn't her other 2 children's names either. Son is the only odd one out, so would be easier for his name to be changed.
My friend is wondering is the ex correct, does she stand a good chance of a judge approving the name change?
