Estate planning for unmarried partners

On Behalf of | Aug 24, 2026 | Estate Planning

Unmarried partners can face unexpected challenges when planning for the future. Washington law does not automatically grant inheritance rights to partners who are not married, making a customized estate plan essential.

Thoughtful preparation helps protect shared property, financial stability and personal wishes while reducing the risk of confusion during difficult moments.

Washington laws for unmarried partners

Washington does not treat unmarried partners the same as married spouses for inheritance purposes. Your partner may receive nothing without valid documents that outline your specific instructions. Detail-oriented planning helps ensure that your wishes are honored and estate documents that address your unique situation can create a strong foundation for your plan.

Documents that support long‑term stability

Unwed partners benefit from several core documents that outline authority and access. Following are examples of important tools:

  • A will outlines how property should pass at death.
  • Trusts help manage assets and may reduce the need for probate.
  • Powers of attorney grant authority to act during incapacity.
  • Health care directives communicate medical preferences.

Together, these documents create a plan that reflects your wishes and protects your loved ones.

Shared property and financial interests

Many unmarried partners own homes, vehicles and financial accounts together. Clear titling and coordinated beneficiary designations can help reduce uncertainty. Washington community property rules do not apply to unmarried couples, so careful planning is essential. A trust or a written agreement can help preserve stability if one partner dies or becomes incapacitated.

Unfortunately, disagreements with relatives or other interested parties can arise after an unmarried partner passes away. With experienced legal guidance, you and your partner can help protect your final wishes and facilitate a smooth legal process.
