For background, please review the information we have assembled and posted at http://willicklawgroup.com/property-rights-and-division/. Specifically review the posted article on "disproportionate division." Your story is a bit vague, but there is also some chance that the "transmutation" could be attacked on the basis of fraud, depending on some facts that are not well developed and really would require a consultation to flesh out. It is a bit unclear from what you wrote whether your spouse might already have a substantial interest in the home even before the title change -- it depends on a bunch of facts, including the various time periods of purchase and marriage, how much money went into it, from where, when, and why. You really are going to need an in-depth conversation with a family law specialist well versed in community property law.
