Re: what paper I need
If the change of ownership and the new loan are all part of the same transaction; that is, both happen more or less at the same time and one more or less depends upon the other, it might be possible to rely upon the lender (not the loan broker!) and the lender's escrow and title company to prepare all the documentation. This is the lowest cost approach that is relatively safe from future problems. Filling out and recording deeds yourself could work, but the possibility of a costly error is quite high and so this is a not a good choice.
The safest approach is to use a lawyer to review the background reasons for doing this deal and advise on its overall wisdom, then if it passes muster, to draw up bulletproof documents.
Among the common problems that lawyers (and judges) frequently see with deals like this are (1) the spouses are trying to hide assets from a creditor with a claim against the transferor spouse, and (2) the deal results in an unforseen tax problem, either because the property is reassessed and loses its low Prop. 13 valuation, or there is a step-up in basis that triggers a gift tax or capital-gains tax liability. The tax man is almost certain to find out; he monitors recorded deeds and investigates.
Transfers of property between spouses are a fraud on creditors if they have the effect, broadly speaking, of "hindering, delaying or defrauding" a creditor with an existing or even a potential claim against the transferor.
I suggest review by a tax and fraudulent-transfer savvy attorney. Real estate prices are still high enough, and tax and fraud problems costly enough, to make a few hundred bucks of professional fees for a consultation a very good investment.
