Your post is more relevant to this topic and I was also confused about. Means I was thinking that child does not contain pure genes of yours. He/she has surrogate mother genes too. Low and more her habits too. As far as my knowledge is concerned with this post then I would like to share my point here. Most of the clinic have a legal right to do as. Means they acquire passport or real documents from both surrogate mother and parents. They make a report and stamp on it that this child is no more belong to this surrogate mother. After your clearance from the clinic, they provide you such legal and authorized facilities. These services are not too late. Right after the day of their clearance, they hand over their original documents with a birth certificate of kid. So this shows the clinic sincerity and pureness. Otherwise similar to this treatment clinic plays fraud. They cheat you by playing with your emotions. So have a great day!!!
