A certificate of trust is the short document you hand a bank or title company instead of your full trust. It proves the trust exists, names the trustee, and confirms the trustee's powers - without revealing who inherits what. The trust itself stays private, which is half the reason you created it.
You will use it whenever an institution needs to verify the trust: opening or retitling accounts, refinancing trust-held property, or closing a sale. Most institutions accept a certification in place of the full document, and estate professionals prepare one alongside the trust as standard practice.
If an institution demands the entire trust, ask about their certification process first - the certificate exists precisely so your family's arrangements are not filed in a lender's records.
