I have with one of mine. The Lawyer a couple of times asked me to try and get with him and leave something for him.I flat out told the Lawyer, I was through trying to get through to him after 2 plus years of trying. No more.Now what I did do, and checked with his wife (who does talk with me rationally) is I set up a special Account with my Financial Agent for their son, my Grandson.He can collect at 18 if he goes to College or at 21 if no College. If some unfortunate problem takes place before he can collect, then it goes to my Daughter. If she cannot collect it goes to a Charity of my choice.Note: If for some reason my Grandson turns out to be a problem when older, crime, drugs, whatever, then he also will get nothing. This has been written up very legally and checked off properly. Thereu2019s more to this as it does get quite involved in the Legal Aspect of it all.I doubt just checking a Box would cover everything as you read about family fighting and going to court. You need to be very legal through a good Will LawyerI consider it a worthwhile cost to have done this.I covered my bases my way and my son gets zip.How common this is, I have no idea, but no way will he get any.
