Buying a used car from a private seller in California

Buying from a private seller can save money. Here is what to collect at the sale and what you owe the DMV afterward.

Get these from the seller

Transfer within 10 days

You have 10 days from the purchase to transfer the car into your name, by mail or at a DMV office. Transfer fees are due within 10 days, and penalties apply if they are not paid within 30 days.

What you pay

Buying from family

Use tax does not apply to a purchase from a parent, grandparent, child, grandchild, spouse or registered domestic partner who isn't a dealer. Stepparents, stepchildren and ex-spouses do not qualify unless there was a legal adoption. Bring proof of the relationship.
