Is It a Good Idea to Add Your Child to Title on Your Home?

Many clients ask whether adding a son or daughter to their home's title is a simple way to avoid probate. The answer is almost always no — and the unintended consequences can be significant.

Adding someone to title on your home may seem straightforward — it can be done with a deed through a title company. But whether a child should be added is a very different question. Most people don't fully understand the legal and tax consequences of making that transfer during their lifetime. This post addresses the most important ones.

What Proposition 19 changed

With the passage of California Proposition 19, a transfer to a child — even a partial interest — will not avoid property tax reassessment unless the child makes the home their primary residence. To qualify for the parent-child exclusion from reassessment, the child must move in and establish it as their primary residence within one year of the transfer, and file for the homeowner's exemption within that same window. If those conditions aren't met, the transfer triggers a full reassessment at current market value.

Tax and legal consequences of adding a child to title

1. 1. Gift Tax Consequences. Adding a child to title constitutes a taxable gift. The parent would be required to file a gift tax return reporting the gift — equal to one-half the value of the property. The balance over the annual gift tax exclusion amount (currently $19,000 per year) is taxable to the parent, not the child. In some cases, a gift tax may actually have to be paid.
2. 2. Reduction of Lifetime Exemption Amount. Even if no gift tax is owed at the time of filing, reporting the gift reduces the parent's federal lifetime exemption — the amount an estate can shelter from federal estate taxes. Depending on the tax laws in the year of death, the estate may face estate taxes because too much of that lifetime exemption was used during life.
3. 3. Capital Gains Tax Consequences. When a parent dies and leaves a house to their children, the home typically receives a stepped-up tax basis to its fair market value at the time of death. This minimizes capital gains tax if the children later sell the property. But a home does not receive a step-up in basis if a child is added to title during the parent's lifetime. The child retains the parent's original cost basis — the price the parent paid when they first purchased the property. If the home has appreciated significantly, a future sale will trigger a large capital gains tax that would not have existed if the home had passed at death instead.
4. 4. Additional Property Tax Consequences for Siblings. Parents sometimes add one child to title thinking it will make it easier to share the asset among multiple children later. But this creates additional property tax problems. If the child on title then transfers a portion to a sibling, that transfer is itself a taxable gift with potential gift tax consequences. Moreover, a transfer between siblings triggers property tax reassessment on the transferred share — which can be a serious problem if the children intended to keep the property.
5. 5. Other Unintended Consequences. Adding a child to title exposes the property to that child's creditors — including an ex-spouse in a divorce proceeding, or a judgment creditor from a lawsuit. And if the parent-child relationship sours (which does happen), the parent cannot force the child to deed the property back. Once the transfer is made, the child is a co-owner with full legal rights.

So what's the right approach?

For most California homeowners, a revocable living trust is the correct tool. A trust allows property to pass to your children at death without going through probate, while preserving the step-up in tax basis, avoiding gift tax complications, and keeping the property out of reach of a child's creditors during your lifetime. It also lets you retain complete control of the property while you're alive.
