I am adopted and a number of years ago I made contact with my biological father. We had a private dna test done which confirmed the relationship. He married but had no children. he recently advised that him and his wife were providing for me in their will. He is of the understanding that I will be taxed as a child because of the Dna test but I'm not so sure. The test we did was conducted in private IE not by doctor therefore may not be recognised in court or by revenue. Can anyone clarify if this is the case? Or is there anything we can do to ensure I am taxed as a son or daughter.
