My husband has a will and will leave one-quarter of his estate to his two sons (to be divided equally). He is wanting to go ahead and place their names on some investments (which would total the one-quarter now along with his name. These are children from a prior marriage and we have no children between us. I am hesitant to do this because I am afraid the next step will be to go ahead and give them their inheritance. They are 54 and 45 in age. Need some legal advice.
