Only one spouse needs to be 55 or older, and that spouse must own both homes. Each person has three transfers in a lifetime, and the transfer is claimed by the qualifying spouse.
4 min read · Checked against BOE: 4 November 2026 · [Reviewer: pending attorney review]
Last checked November 4, 2026. Prop 19 lets a homeowner who is 55 or older sell their principal residence and carry its taxable value to a new home anywhere in California. For married couples, the rules are friendlier than many people expect. Only one spouse needs to be 55 or older, and that spouse must own both homes. Each point below comes from the Board of Equalization (BOE) and its letters to county assessors.
Only one spouse needs to be 55
BOE's answer is direct. If one spouse is 55 or older and the other is not, the older spouse can transfer the value, as long as that spouse is on title to the original home on the date it sells and on title to the new home on the date it is bought. BOE adds that it does not matter if the other spouse is not yet 55, and both spouses do not need to be on title.
In BOE's later wording, the spouse who is 55 or older must be "an owner of both" homes, and the younger spouse "will not preclude the other from qualifying." The who qualifies page walks through the full list.
The age that counts is on the sale date
The spouse who files must be at least 55 on the day the original home sells. BOE gives the example of a wife who is 50 and a husband who is 54. They can buy the new home first and sell the old one after he turns 55. He is then the claimant.
Whose name is on the deed matters
BOE starts from the deed. The people listed on it are presumed to be the owners. Two BOE examples show why this matters.
- If the home belongs only to one spouse, for example a home she inherited from her mother, only she can be the claimant. Her husband's age does not count, even if he is older.
- If the couple bought the home during the marriage but only one spouse is on the deed, the other spouse can claim only if the assessor is persuaded that spouse is really an owner. BOE lists the kind of proof that helps: a written agreement, cancelled checks, insurance policies and tax returns.
If the older spouse is not on title today, talk to the assessor and an attorney before you list the home.
Three transfers for each person
Under Prop 19, each person can use the 55 or older transfer up to three times in a lifetime. The claim form, BOE-19-B, asks the claimant for a Social Security number, which the state uses to stop more than three transfers. It also asks whether you have used a Prop 19 transfer before, and where.
BOE's published answers do not say whether a claim filed by one spouse also counts against the other spouse. If you are planning more than one move, ask the assessor how your claim will be counted before you file. The BOE-19-B form guide shows where these questions sit on the form.
A Prop 60 or Prop 90 transfer used before April 1, 2021 does not reduce the three.
Your children can be on title to the new home
Many couples need help from a son or daughter to buy the next home. BOE says the law does not require the claimant to be the only owner of the new home. As long as everyone on title buys it together and you are one of the buyers, a child on title does not affect your eligibility. You can transfer your value to the whole new home, even if you own only part of it.
If you divorce
Two BOE answers cover this.
- If one spouse keeps the house and the other buys a new home, the buyer cannot transfer the value. A transfer between spouses, including one under a divorce settlement, is not reassessed, so the original home was never sold.
- If you sell the shared home and each buy a new one, only one of you can take the benefit. If both qualify, you decide between you who gets it.
If a spouse dies
BOE says a transfer to a spouse, including a transfer at the death of a spouse, is automatically excluded from reassessment. The surviving spouse keeps the home at its current taxable value. If the survivor is 55 or older, owns the home and lives in it, they can later sell and use Prop 19 like anyone else. BOE says the law is silent on how you came to own the original home.

Quick questions
Do both of us have to be 55 to use Prop 19?
No. Only one spouse needs to be 55 or older on the sale date, and that spouse must own both the old home and the new home.
Does the younger spouse have to be on title?
No. BOE says both spouses do not need to be on title. The spouse who is 55 or older must be.
Can our children be on title to the new home with us?
Yes. BOE says a child on title does not affect your eligibility, as long as you buy the home together and you are one of the buyers.
If we divorce and each buy a home, can we both transfer the old value?
No. BOE says only one co-owner can receive the benefit from the shared home, so you decide between you who gets it.
What happens to our home if one of us dies?
A transfer to a surviving spouse is not reassessed. The survivor can later use Prop 19 if they meet the usual rules.
