state TX--posted previously about inheritance. Briefly, this a 48 year marriage with Dad fulfilling his "needs" on the side for the last 5 years. (just discovered this month)

Now the question is: does my Mom stay in the house while she is getting her "ducks in a row" (retaining attorney, trying to gather more evidence about my philandering father) or does she leave now? I have printed documentation of an encounter just last month. He's using a web site, but has now changed his password. Thank you for any advice that you are able to offer.
