The will was drafted using information obtained online. The will is not notorized but, it was signed by two witnesses -- my mother (my father's living spouse) and my (living) spouse. I'm the only son; I'm named as a significant beneficiary plus, the executor of his estate. We have been told the will is invalid but, that it still needs to be filed with the court. We live in the State of Washington. So, what am I suppose to do now? Do I go ahead and proceed to administer the will or what?
