I moved two sims in together and when they got married, the female still has the same last name she did before they got married, and their child has her last name.

There's a workaround. I can't remember right now if I had to have Origin online or not -- I think I had it off -- but anyway, here it is:Ctrl-Shift-Ctestingcheats truecas.fulleditmode (edited to add this, left it out before, sorry)Shift-Click on your Sim and choose "Modify in CAS" This takes you to CAS, where you can change the name.You can also change the household name by going to Manage World. There's no cheat involved in this one. Just choose the family and change the household name.I was successful in changing the wife's name, the child's name, and the household name using these methods.

I was watching an LP and that happened. Score 1 for feminism but 0 for you if you want to change the names. IDK who the kids got the last name from.

This happened to me too. You can choose the babies last name upon birth, but either spouse's original last name stays the same as before they were married.

You cannot change the last name in CAS via testing cheats. It tells you that you cannot modify pre-created sims or something along those lines. You can only edit their appearance through that.And this happens to me, too. I reported it last night and posted in the bug thread. Had a sim host a wedding party, after the party ended his new spouse went home along with the other guests and her last name did not change. Nice work, Sims team! How many expansions do we have to wait through for this to be rectified? I enjoy the game but these little things are starting to build up and get to me. They really dropped the ball when it comes to sims relationships with one another. No family trees, no real in-depth relationships between family members, the only relationships you have indicated via the panel are the bare basics: sibling, parent, grandparent. No uncles, no cousins (far as I am aware), no in-laws. The new emotions system is all froth and no substance when features that would tie it them together are missing. I had the parents of a sim die and they didn't even feel sad about because they didn't witness the deaths! Another sim-child's parents got divorced right in front of him and he didn't even react, no sad mood, nothing! Really missing the old aspirations system in TS3 with wants/fears and decent aspirations. If TS3 actually played without stuttering like it's sinking into a swamp, I would go back to it until expansions are released for TS4 but I can't stand even the minimal amount of stutter.

Last name didn't change after getting married.

When my sims got married, the woman changed her last name, and I DIDN'T want that like plum. Is there a way I can get her last name back?! This is really frustrating me! Not all females change their names when they get married! I'm going to keep mine for example when I get married just like my mom and 8th grade science teacher did! Why can't the man just change his name for God's sake.

You can change Sims' names anytime you're in CAS, even if it's just Plan Outfits.

Sims don't automatically change their name in Sims 4. Do you use MC Command Center? It has name-changing settings - check what yours are set at.

I don't use cheats to change the last name. I go to a mirror and click on change appearance and it allows me to change the last names of my Sims....

This is an old topic, though, dating back to when you still needed to use the cas.fulleditmode cheat.

All you have to do is go onto plan outfit via mirror or dresser and click on the sim's name in cas. You can change it there without cheats.

Does anyone realize this thread is almost as old as The Sims 4 itself?

I had the same thing happen too and don't see an obvious way to rename.

Can anyone out there confirm whether this happens with all marriages or not?

If you get the message "Cannot edit an existing Sim," try putting Origin offline. I swear to you, folks, I have successfully renamed my Sims. Let me see if I can get some screen shots.

Here's how you do it:

1. Ctrl+Shift+C to bring up the cheat menu.
2. Type "testingcheats true" and hit enter.
3. Type "cas.fulleditmode" and hit enter.
4. Shift+Click your Sim and choose edit in CAS.

I've run into an issue. Their relationships are screwed up now. I changed a daughter and mother's last name and when I went out they were listed as sisters along with their aunt (mother's sister). So I guess weird names are sticking until they fix it!
