Disabled brother died - no Will. My husband and I were his Guardians - 100% decision making. I have one nephew and 2 daughters

You need to speak to an attorney in Washington State for advice. I do not think that both you and your kids would each be entitled to shares....

My father died without a will and I am the next of kin, what do I need to do to receive his assets?

You need to conduct an administration in NYS in the county in which he resided in at the time of death.

No you cannot. You cannot serve her with papers.

At our first custody/divorce pretrial the Judge gave temporary custody to father without considering the best interest of her.

Divorce trial and final judgment ?

As counsel said, there is no set time.

it seems that its over in June of 2018. .............

My company has no returns right now and i am filing for a divorce, can my wife take advantage of the company after the divorce ?

If your company is only 4 months old, then its unlikely it is worth much more than the money placed into it at its incorporation.

Do I listen to dismiss my custody petition and refile in 6months? The attorney said I would not win.

Your attorney knows your case much better than anyone else on here.

Can my daughter's father make me move back?

If a petition is filed you need to retain counsel.

What are my options and what can I do about my ex and his girlfriend alienating me from our child?

It sounds like you need to retain local counsel to review the agreement, and advise you going forward.
