How to Get Teenage Sims Married in Sims 2

Make two teens. If they are in the same household, don’t make them related. Enter the house, and if the second teen is not already there, make sure they’re friends with someone in the family and invite them over.

Open up the cheats box by pressing CTRL + SHIFT + C and type “ageSimsCheat on” (without the apostrophes.)

Open up the cheat box again and type “boolProp testingcheatsenabled true” (again, without the apostrophes.)

If one of the Sims has been invited over, click on them and press shift. A menu should appear. Click on the option that says “Make Selectable”. If all Sims in question are already members of the household, ignore this step.

Left-click on one of them and choose “Set Age...” and “Adult”. They will turn into an adult. Repeat with the other Sim.

Get them married as normal.
