Trust Funding: Definition and How It Works in California

By Eric Ridley, attorney, Ridley Law. Updated September 2026.

Trust funding is the process of retitling assets, by deed, account change, or assignment, into the name of a living trust. A trust only controls what it actually owns, so anything left out of it can still end up in probate.

How it works in California

Signing a trust document does not, by itself, move any property into the trust. Trust funding in California is a separate step: retitling real estate by recorded deed, changing the owner of bank and brokerage accounts, and assigning personal property to the trustee.

Because funding touches every asset a person owns, it is easy to miss something, especially an account opened after the trust was signed. Ridley Law’s trust funding checklist walks through the categories of assets one at a time.

People often assume their trust is funded because they signed it, when each asset has to be retitled and kept that way. Anyone unsure should check whether their living trust is actually funded before assuming it is.

Why it matters

For example, a family discovers after a parent’s death that the family home was never deeded into the trust. The home may then need probate or a court petition to bring it into the trust, even though the trust was otherwise complete and current.

Common mistakes

People fund the trust once at signing and never revisit it after buying a new house or opening a new account. Others assume a beneficiary designation on a retirement account or life insurance policy accomplishes the same thing as funding, when those pass by contract, outside the trust entirely.
