Changing daughter's surname

[Kate96]

Hi,
I have a question that I hope you can help me with:
I separated from my ex last year.
We have a daughter 5 y.o who leaves with me and the father has the usual contact arragements (overnight wednesdays and every other weekend)
The father is registered on the birth certificate and my daughter carries the father's surname as it is written at the BC.
I hate to have to put my childs name using the father's surname, when I have to enrol her in the school, ballet classes, swimming, etc.
I have been told that I cannot change my daughter's surnmame but I am assuming this only applies to the official birth certificate unless I have his consent, which obviously he will refuse.
Does any off you have the same feeling that me?
would I be in trouble if I just change my daughter's name to mine on every day occasion as explained above?
It is my child and I do not want to be reminded of him every time I hear his name.
Can anyone help / advise?
Thanks in advance to all
regards
Katie

I like the idea given by fontofnoknowledge above.
We could change the birth ceritificate to per example:
Jane Mysinski-Smith.
Once this is done and officially changed on her BC, I could always write my daugther's name as Jane M. Smith. This way the problem is solved and no one would be able to say that it is not legal, right?

I this possible?

It is my child and I do not want to be reminded of him every time I hear his name

She's also his child, but thats not the point. You chose her name, now its hers. You don't get to change her name because of your relationships.

Well, it is not only that I hate that, it is also that the father if polish and the surname is difficult for everyone to pronounce. Also, I feel that my little girl can be treated differently by others. "discriminated" if you like, and I do not want that she experience or feels that way.#

Oh come off it, that didn't stop you doing it in the first place, its just a convenient (and kinda offensive) excuse now to get what you want.

You cannot change the birth certificate, ever. Unless it's proven he's not the father or some other fraud has occurred I believe. I changed my sons name to his fathers as it meant more to him than my name does to me and him and I had to sign an agreement in front of a solicitor, who also had to sign and stamp it.

I don't have the name of my 3 sons and it doesn't bother me in the slightest, I'm more than secure enough in my parental role to be ok with it.

Just to add, we are also separated

No, not possible to change the birth certificate as you've already been told.

OP I am not sure you understood my suggestion. I specifically put the made up polish name last as it is, and always will be her surname as per her birth certificate. I did not suggest 'Mysinski-Smith as Smith (whatever your surname is..is NOT her surname and you cant unilaterally change it. ). I suggested 'smith-Mysinski because that creates a connection to you WITHOU removing or altering her legal surname.

Yes, to answer your question you can't change a surname because you don't like her father. You made a baby with them. Gave his name. He has equal rights.
