This is a script mod that ensures newborn Sims automatically inherit their father’s last name, improving realism and consistency—especially useful for legacy gameplay.
The mod offers three different versions to suit various gameplay styles:
- One where the father’s last name is passed to the child only if the parents are married.
- One where the child takes the father’s name if the parents are in any romantic relationship (dating, engaged, etc.).
- One where the child always takes the father’s last name, regardless of relationship status.
The process is automatic when babies are born in-game, but you can also trigger it manually using a console command: reve.last_name_update. There are additional commands for selecting specific Sims or checking parental relationships if needed.
The mod is compatible with the base game and doesn’t require any expansion packs. It has been updated to include optional pop-up notifications when a last name change occurs, and recent improvements have refined how and when the mod runs. It’s a simple but impactful tool for players who value family cohesion and generational storytelling.
