Legal Question in Wills and Trusts in California

You might create a living trust and transfer the house to the trust now. Then, upon your passing, the property could be transferred to whomever you designate in the trust.

For tax purposes and avoidance of probate, it would be best if you set up a living trust and left it to them through the trust. If you deed it to them now, they would receive your basis for tax purposes, which might create a large capital gains tax if they ever sell it. Using a will would be much more expensive than creating a trust, because of probate fees.
