Legal Question in Real Estate Law in California

Re: property tax

No. But you can sue for reimbursement on a theory of unjust enrichment and when reduced to judgment, recording the judgment will result in a lien on the property.

Re: property tax

I agree with Mr. Roth that you cannot put a tax lien on property; only the taxing authorities can do that. I disagree with the idea of suing for unjust enrichment. That won't fly, because you've probably paid with community funds, and the taxes on property your husband co-owns are his responsibility as much as his ex-wife's. The recourse for eventual recovery of the tax payments is when the property is eventually sold, by partition or whatever; you and he would have a claim for reimbursement of yours and his excess contribution to the taxes.
