Receiving a house as a gift

[Ronald Luangsisongkham]

Background story:

My parent's went though a divorce and my mom owns the house. She doesn't want it any longer and wants to give it to me. She hasn't lived at the house for two years. Unfortunately, my dad is house squatting and wont leave. He doesn't provide any help financially.

Course of action:

She is afraid to kick him out for some odd reason. Since she doesn't want to remove him I thought that she should put the house under my name and I'll become the owner and evict him.

Conclusion:

What would be the best course of action to transfer the title into my name in the state of Washington. In addition, what would the best way to remove him from the property without him knowing it was me? Could I hire someone to post a notice? The reason being is I don't want any backlash going back to my mother because my dad has violent tendencies and I want to solve this in the most civil way possible. 

Thank you very much,

Ronald
