I'm confused on how you had a child with someone and dont know how to spell their name correctly on the birth certificate

If that’s how they spell it, it isn’t really spelled wrong. Just differently than how his father spelled it.

My husband and sister in law both have name typos on their birth certificates. 🤷‍♀️

Not me personally but I have a friend who’s last name is common, but spelled differently than it usually is. The story he gets from his mom is that she wanted to give h his (absent) father’s last name, but not exactly so she changed the spelling. Doesn’t make much sense to me but sometimes people are weird.

My middle name is DeAnne and no official document allows for the capital A 😂

My last name is spelled "wrong", so I'm the only one in my family with my spelling. I never knew my last name was spelled differently until I was a grown up and needed to get a passport to study abroad. Don't know why or how it happened in the first place.

What's the last name and what should it actually be ? That's crazy

I am SO curious about what the last name is, but I guess you didn’t put it for a reason. Honestly, if your partner and the baby’s name are spelled the same way, I would leave it and just let people make silly comments. I know someone whose last name if Ffrench WITH the double F and she doesn’t know where it came from, but her whole family spells it that way and has for generations. My husband’s half sister has her father’s last name and the grandparents changed the spelling from MacDonnel to MacDonell just to change the pronunciation to Mac-Do-nell instead of Mac-Donn-ul.And, my family also changed the spelling of their name to a similar French surname, but pronounce it in a more anglo way, so people do kind of get confused but it’s pretty common to do that too. Don’t sweat it. Think of it as a tradition in your family that starts with your husband. If it really bothers him, then let him take the lead on it. Otherwise, that is his name and it would be fine if people weren’t making stupid comments, so 🤷‍♀️

I have a friend whose family name was misspelled due to miscommunication during their immigration process. They just kept the misspelling to avoid the paperwork. My friend didn’t find out until years later.

So your MIL is being vague about why the spelling is different? I’d wonder if she did it intentionally for a reason that she doesn’t want to get Into at this point. I will say that my BIL’s family, who live in Israel, have a name that they spell one way in the states, but his parents spell slightly differently in Israel. It has two “s” in the states and one in Israel. It was odd when I noticed it, but it’s not the hugest deal because I don’t have any legalDocuments hinging on this.
