My wife's oldest sister hasn't talked to her family in almost 25 or more years. She had to have her own viewing when their father and brother died. After their dad passed away she and her husband pulled in and honked the horn. She was driving. I went out and she asked if my wife (her sister) was home. I said no. Then she proceeded to tell me that she had to go and get a copy of the will. I told her we never got one either. Their mom is still alive so everything was passed to her. This upset the wife's sister. She doesn't want anything to do with the family
but when she thinks she should be included she's right in front. She's just a Beach. Oops I spelt that wrong... we don't have spell check on here so I guess I'm ok...LOL! Try to get your mother In law some help for her depression. Sounds like the FIL is causing it.
