You write a notice to quit for non payment and destruction of property, and then evict. Eviction needs to be started down at your court house, and will take a minimum of 30 days.
This would be true if they are family or not, minor child or adult child.
If any violence against you happens, call the police, and get a restraining order.

It doesn't matter whether they are a family member or not. If there was an agreement to pay rent and they stop paying you can give them a pay or quit notice. Is this Wash State or Wash DC. the length of time for a pay or quit is different.

If they don't pay in full, then you go to court for an eviction order.
