Buying Out Your Spouse Does Not Reassess the House
Program and regulatory figures verified October 10, 2026. Details change; confirm your scenario with us.
In most states property tax is a background escrow line. In California it can be the whole difference between a payment that works and one that does not.
★★★ Why this is the biggest number on a California buyout
Under Proposition 13 a home's assessed value is anchored to when it was acquired, with limited annual increases. A house bought decades ago can be assessed far below what it is worth today, and the property tax follows the assessed value.
★★★ So the question in any California transfer is: does this reset the clock? If a buyout were a change of ownership, the home would be reassessed at current value and the tax could rise dramatically, on the very payment one spouse now has to carry alone, on one income. That would sink a great many otherwise workable buyouts.
The statute
Rev. & Tax. Code § 63, verbatim:
"Notwithstanding any other provision in this chapter, a change of ownership shall not include any interspousal transfer, including, but not limited to: (a) Transfers to a trustee for the beneficial use of a spouse… (b) Transfers which take effect upon the death of a spouse, (c) Transfers to a spouse or former spouse in connection with a property settlement agreement or decree of dissolution of a marriage or legal separation, or (d) The creation, transfer, or termination, solely between spouses, of any coowner's interest."
★★ Note three things in the drafting. "Shall not include any interspousal transfer" is the general rule; the list is "including, but not limited to", so it is illustrative rather than exhaustive. ★★★ And limbs (c) and (d) name a divorce buyout almost exactly: a transfer to a former spouse under a settlement or decree, and the termination of a coowner's interest between spouses.
★★★ The part a lender cares about, which nobody writes
Property tax is escrowed into the monthly mortgage payment. That payment is what we underwrite, and what the debt-to-income calculation is run against.
★★★ So § 63 is not only a tax provision. It is the reason the payment we can approve on your buyout is based on the existing assessed value rather than a reassessed one. On a long-held California home that difference can be larger than anything the interest rate does.
★★ Which leads to the practical instruction: tell us the current assessed value and the current annual tax early, not the market value. We can then underwrite the payment you will actually have rather than one built on an assumption.
★★ What we are deliberately not claiming
- ★★★ That no paperwork is required. Section 63 states the exclusion. It does not follow that your county assessor requires nothing of you. Assessors administer this, and an exclusion you never claimed is a conversation you do not want to have after a reassessment notice arrives. Ask your county assessor what they need and when.
- ★★ Anything about Proposition 19. Different statute, different rules, parent-child and over-55 base-year transfers. Not read at a primary source this pass and not necessary to the buyout question. We are silent on it rather than approximate.
- ★ That the exclusion survives anything done afterwards. We quote the provision as it applies to the interspousal transfer itself.
- ★ Any tax advice. We are a lender. This is the text of a statute and what it means for an escrow figure, not tax counsel.
★★ A note on where we read it, because California makes this hard
California's own code site, leginfo.legislature.ca.gov, returned 403 to every user-agent we tried on 2026-10-10, including an ordinary browser. law.justia.com returned 403 as well.
★★ So the Commonwealth's statutes are published where neither a reader's tools nor an AI answer engine can fetch them. We quote from california.public.law, which prints the verbatim section, links back to leginfo as its source, and carries its own verification date. ★ We would rather cite a readable mirror and tell you it is a mirror than cite a URL that fails for everyone. Our sourcing rules.
★ What to do with this
- Pull your current assessed value and annual tax from your county assessor or your tax bill.
- Ask the assessor what, if anything, they want filed for the interspousal exclusion.
- ★ Send us the actual tax figure so the payment is underwritten on it. And the loan rule that sets how it is classified

Frequently asked questions
Does a divorce buyout trigger reassessment in California?
No. Revenue and Taxation Code section 63 provides that a change of ownership shall not include any interspousal transfer, and expressly names transfers to a spouse or former spouse in connection with a property settlement agreement or decree of dissolution, and the creation, transfer or termination solely between spouses of any coowner's interest.Will my property tax go up if I buy out my ex in California?
Not as a result of the transfer itself. Because section 63 excludes interspousal transfers from change-of-ownership treatment, the assessed value is unchanged, so the property tax escrowed into the monthly mortgage payment does not jump.Do I need to file anything with the county assessor for the interspousal exclusion?
We do not publish an answer. Section 63 states the exclusion but it does not follow that your county assessor requires no filing, and assessors administer this. Ask your county assessor what they need and by when.Why does this site cite a mirror instead of the California legislature?
