Family/friends noticed confusion, memory loss when Father made a Will in 1998. Daughter tried protecting his possessions and property but Father believed she was trying to steal from him. Things worsened so daughters brought him to S. Carolina, purchased home with father's money and cared for him in it for 11 years until his 2012 death. In May-2013, Father's attorney in WA filed Declination to Act as Executor and Father's 1999 Will. It was at that time his daughters learned Father changed his Will, removing them as beneficiaries and leaving everything to father's brother and nephew. Daughter contacted father's brother/beneficiary who gave a written statement that his brother was not of sound mind when the 1999 Will was made. Now what?
