Probably mid-30's. He is 63 now; they were married in the mid-90's, but they had the child first. The guy I'm looking looking was 59 and had a 40 year old girlfriend, who worked for him. I guess it's just a matter of personal tastes as to the ick-factor, but it isn't illegal. I wouldn't call it unethical if he didn't represent her after the emancipation. You can date someone after she's been a client.
