When Ancillary Probate Is Required: Multi-State Estates in Washington

Oct 13, 2025 | Blog, Estate Planning, Probate

October, National Estate Planning Awareness Month, is a crucial reminder for all families to consider their future, especially those with connections spanning across state lines. While estate planning aims to simplify asset distribution and avoid family stress, multi-state estates introduce a unique layer of complexity known as “ancillary probate.” This blog post will explain what ancillary probate is, when it’s required in Washington State, and how proactive planning can help you navigate this intricate legal process.

What is Ancillary Probate?

Ancillary probate is a secondary probate proceeding required when a deceased person owned real estate in a state other than the one where their primary probate (domiciliary probate) is taking place. For example, if a Washington resident owns a vacation home in Oregon, their estate would undergo primary probate in Washington, but a separate, “ancillary” probate would be needed in Oregon to legally transfer the title of the vacation home.

When is it Required in Washington?

Ancillary probate is required in Washington State if a non-resident decedent owned real property (like land or a home) located within Washington’s borders. Similarly, a Washington resident’s estate would need ancillary probate in any other state where they owned real property.

Assets Requiring Ancillary Probate

The primary asset that almost always triggers ancillary probate is real estate (land, houses, condos). Other assets, such as bank accounts, vehicles, or personal belongings, generally do not necessitate ancillary probate in another state, as they are typically handled under the laws of the decedent’s primary residence.

Why It Matters for Washington Residents

The general probate process in Washington already carries disadvantages such as delays, financial costs, and a complete lack of privacy, as all records become public. Ancillary probate magnifies these issues because it means going through a separate, additional court process in another jurisdiction, incurring extra legal fees, court costs, and potentially more time delays. For Seattle families, whose homes are often their largest asset with values well over $863,000, owning property elsewhere can quickly complicate an already substantial estate.

Avoiding the Complexity

The goal of effective estate planning is to ensure personal wishes are formally documented and carried out, alleviating potential confusion and stress for family members. For multi-state estates, this means strategically structuring your asset ownership to bypass probate altogether.

• Trusts: A “living trust,” which is created and funded during your lifetime, allows assets to be distributed privately and efficiently after death, avoiding the time, expense, and public nature of probate court. If all real estate (both in Washington and other states) is properly transferred into a living trust during your lifetime, ancillary probate can often be entirely avoided.

• Joint Ownership: Owning property as “joint tenants with right of survivorship” or “tenants by the entirety” can allow the property to pass directly to the surviving owner without probate. However, this strategy has its own complexities and potential downsides that should be discussed with an attorney.

• Transfer-on-Death (TOD) Deeds: Some states allow for “Transfer-on-Death” deeds for real estate, which function similarly to beneficiary designations for financial accounts, allowing the property to pass directly to a named beneficiary upon the owner’s death without probate. Washington State has adopted this option for real property.

Charting Your Course with Confidence

Attempting a do-it-yourself estate plan, especially for multi-state assets, is a “dangerous gamble”. The complexities of Washington’s community property laws, combined with the unique requirements of other states, make this area highly specialized. A generic online template is unlikely to adequately address the nuances of your situation and can lead to irreversible financial harm.

Assembling a team of qualified professionals, starting with an experienced estate planning attorney licensed in Washington, is critical. They can help you create a comprehensive and legally sound plan that minimizes the need for ancillary probate, ensuring your family is protected and your legacy is preserved exactly as you intend.
