My question involves estate proceedings in the state of Washington.
My father set up a partnership between 2 sisters and me and named older sister as General Partner. The Partnership has assets at a bank and their brokerage. The General Partner had stopped communicating and younger sister and I voted her out and informed the bank. Older sister protested to bank and bank has stepped back, informing us we must all agree on any decision in writing. Bank now lists younger sister as General Partner with address here in WA State, with her home being close to me. Partnership Agreement states it is to be terminated two years after father's death, now well past that time. I need to have my proceeds and apparently must bring a suit. I intend to bring suit here in WA and stand on the earlier vote for new General Partner, with her address here. Since the bank requires all partners to agree in writing, I will name both sisters. I definitely need to name the older sister (former General Partner) to compel her, and having her respond to a WA Court will help as she lives in another state (and is an attorney there).
1. Should I name the bank and brokerage (located in that other state), so that they are given instructions at the conclusion of the trial?
2. Is there any strategy I can bring to bear to stack the odds against the sister who is an attorney in another state?
3. I am guessing I should take this to District Court, correct?
4. Can I name the younger (friendlier) sister in a distinctive manner in the suit, to show she must respond but is not being attacked?
5. Where may I find an outline of the procedure I need to learn and follow, to bring suit and repond to any motions (change of venue, etc.)
Thanks!
