Sims that move into a household may bring some money from their old household along with them. Like normal Sims, both the inviting Sim and the animal must have a good relationship with each other before the option to adopt becomes available. Children cannot be invited to moved in using this method. In The Sims, up until The Sims 2: University a Sim that is moved in this way will change their surname to match the household they moved into, even if they were not getting married. Sims that get married will also move in to the household of the proposing Sim. Both the playable Sim and the other Sim must have a good relationship with each other before the interaction becomes available.
