Help: Weird birth certificate typo situation

[HardRocker1999 0]

So basically,

 

My step mom (LPR) is going to sponsor me. There is a little problem . My UK birth certificate has a one-letter typo for mine and my dad's surname (we have the same surname). 

By typo I mean that it is different from both our passports and other main documents. I actually asked the birth certificate years ago about correcting this, but they said unless there's evidence from around the time of birth they can't correct anything. I don't have any of the documents they're asking for. 

 

Because of this, many years ago I used a deed poll (basically I legally changed my name) to correct the weird typo, just so my name would be correct. This was before I planned on immigrating to the US. It corrected my passport but never solved my birth certificate. 

 

 

My younger sister's birth certificate on the other hand is completely correct and she wouldn't have any issues. Could that perhaps be used as a reference point?

 

I really am unsure of what to make of this. Is this something that's negligible and won't cause a problem? Or will it be an issue establishing that I am indeed my father's son (and thus proving the relation with my step mom). Even if it's a one letter typo? Does this happen alot?

 

I just feel it would be a shame if we would have to lose out just because of this reason, especially since it's something that wasn't my fault, and that I was literally a baby during this.

Would affidavits suffice here? If it stated that my correct name and the birth certificate name are one and the same person, and also stating the same about my father and his name. How would it need to be formatted? How many would I need here?

 

Would my biological mother be eligible to do it, considering she's divorced from my father.

 

How about my father himself. I saw somewhere that someone involved in the petition process insnt allowed to do it. The one that would technically be sponsoring me here is my step mom. Would my father still not be allowed to write an affidavit?

 

Lastly, is it required that they have some kind of notary attestation? Or is it fine that it's signed.

 

Does it need to come with all the fancy legal words to be accepted?
