Why Ancillary Probate Exists

Real estate is governed by the laws of the state where it's physically located — not where the owner lived. This is called the lex situs rule, and it means:

• An Arizona court has no authority to transfer title to real property in Colorado
• A Colorado court has no authority to transfer title to real property in Arizona
• Each state must open its own probate proceeding to transfer title to property within its borders

So if someone dies in Arizona but owned a vacation cabin in Colorado and a rental property in Nevada, their family faces three separate probate proceedings — one in each state — each running independently on its own timeline with its own legal requirements and costs.

What Ancillary Probate Costs

Every ancillary probate proceeding carries its own full set of costs — separate from and in addition to the primary probate:

How a Revocable Living Trust Eliminates Ancillary Probate

A revocable living trust is the only tool that covers real estate in multiple states under one coordinated plan — without requiring separate probate proceedings in each state.

Here's why: when real estate is titled in the trust's name, the trust — not the individual — owns the property. When the trustee dies:

• The trust doesn't die — it continues to exist
• The successor trustee steps in and manages or distributes all trust-held real estate per the trust's instructions
• No court involvement is needed in any state where trust property is held
• The Arizona property, the Colorado cabin, and the Nevada rental all transfer through the same trust administration — one process, one successor trustee, no ancillary probate anywhere

Other Tools That Help — But Have Limitations

If a trust isn't in place, some other options exist for specific situations — but each has significant limitations:

• TOD/Beneficiary Deed in the second state: If the second state recognizes Transfer on Death Deeds or Beneficiary Deeds (Arizona does; Colorado does; many other states do), recording such a deed for the out-of-state property avoids ancillary probate for that property. But this only works if done before death and only covers the named property.
• Joint tenancy with right of survivorship: Property held jointly with a surviving co-owner transfers to the survivor at first death without probate — in any state. But at the second death, ancillary probate is required for all out-of-state property unless additional planning is in place.
• Small estate affidavit: If the out-of-state property is very low value, some states allow a simplified affidavit process instead of full ancillary probate. Dollar thresholds vary significantly by state.

None of these alternatives is as comprehensive or clean as a revocable living trust that holds all properties across all states from the beginning.

Common Mistakes

• Assuming the primary state's probate covers all property. It doesn't. Each state requires its own probate for real estate within its borders. This surprises most families.
• Buying out-of-state property without updating the estate plan. A vacation home or investment property purchased after the trust was created must be deeded into the trust at closing — or as soon as possible after. Forgetting this step creates ancillary probate exposure.
• Using a will and thinking it covers multiple states. An Arizona will instructs Arizona's probate court. It provides no authority to transfer Colorado property. A separate ancillary proceeding is required regardless of what the will says.
• Inheriting out-of-state property without planning. If you inherit real estate in another state, that property is now in your individual name in that state. Without a trust or TOD deed, your heirs will face ancillary probate for it at your death.
• Not researching the second state's probate laws. Different states have different probate timelines, costs, and requirements. A state with particularly slow courts or high attorney fees can turn a manageable ancillary proceeding into a multi-year ordeal.
