Your assumptions are correct. We are getting in touch with a probate attorney today. Would a lawyer be able to fight his children trying to claim anything?
I don't believe that there is anything to fight. The statute is pretty clear. The children are entitled to share in one-half of the estate.
Even if it was purchased during the marriage?
It sounds like you are a bit confused. Please feel free to call my office at 407 661 1177. I will be glad to discuss this with you free of charge.
