Quick Answer
Ancillary probate is a secondary probate proceeding required when a deceased person owned real estate or certain types of property in a state other than where they lived.
Expanded Explanation
When someone dies owning property in another state, a primary probate is opened in their state of residence, and an ancillary probate is opened in the other state to transfer title to that property. For example, if a Colorado resident owns a vacation home in Arizona, the estate may need an ancillary probate in Arizona to pass title of the home to heirs or beneficiaries. This ensures that state-specific legal requirements are met for property located outside the decedent’s home state.
Why It Matters
Ancillary probate can add time and expense to estate administration. Planning tools like trusts or transfer-on-death deeds can help avoid the need for multiple probate proceedings.
