Sister is Executor and will not talk to me, answer an email or answer a text. What can I do?

I have had one mother that I cared for for almost 7 of 13 years with Alzheimer's. She gracefully passed in 2017.

I just spent one month ago 2 weeks in my father's assisted living facility with my father, in his room on a cot. He was on hospice, as my father has lewy body dementia, the start of parkinson's disease as well as primary progressive aphasia.

I have an older sister, and she has always been cordial, but the middle sister will not talk about anything regarding the will, etc. For the last 13 years on and off, I have asked her for an accounting, nothing.

Then the last two years of his life once a month, I would ask for an accounting. Nothing, not even a no.

So, my father has passed on 1/11/2020, and I am so grateful that I was able between my full time work to spend the time with him, and for that I am grateful.

Caregiving, helping people, making a difference is who I am. I am not confrontational, but my sister, when my parents were younger said "ok mom and dad let's go to the bank so I can be on your accounts".

The reality is her husband passed away, and she literally became another person.

So..... here we are... 2 days before my dad's death she sends me a check for 500.00 and says D. Cash this ASAP. L.

So obviously, I have not cashed it, because I am trying to find someone to assist me. I know she has not kept an account, I know my sister, and we were very close until her husband died.

Where in Seattle, WA can I find an attorney to assist me. She also put the house that we all three own (gosh forbid), in an LLC and did not communicate any of that to me.

Clearly, they just want me to go along with everything and keep the peace. Just the way we learned as children. (unfortunately, and god bless her soul as I love her dearly, my mother had an alchol issue when we were children and early adults. Because of our age difference 7 and 9 years, and I am the baby, I was the one that was left alone with my mother, and have quite a different experience on the ending, and the joy of having my mother at her age of 58 become my best friend. The other two sisters always felt guilty for "abandoning me" but the story is the story.

Is my sister qualified to be an executor if she will not speak to me or give me any information about the reading of the will. I have it, and it gives her broad powers, and I know he had assets. But this is believe it or not, not about assets. It is about respecting me as a human being. I am a woman that has been hurt severely by her bullish actions, and her taking all of the family to a lake for the summer and paying for it except my husband and myself. I have two adult boys, that asked her, no response, and two lovely grandchildren. I know later in life, the grandchildren will be people that are able to speak their minds.

What can I do legally, and does anyone know of a good Eldercare Attorney in Washington State.

Thank you.
