Her relation with the other man whom she had a daughter now for 12 yrs terminated. 14yrs later she shows up to my door asking me to sign full custody of our son who has never met me. Further she asked me to give her money which I think is very strange considering she deprive me of having a relation with my son since he was born. I see that I should best consult a lawyer about this. It looks to me that she is trying to replace the money she lost from her previous relation by bringing me in to fill the void. In my opinion I do not believe this is fair use of the laws and for someone to bend the laws as they see fit. She constantly keeps motioning that she can get child support if she wants to but will rather work it out between us and not get the courts involved. It is my reason to seek advice here to decide my next step. Thank you for your advice.

Yes, definitely go see an attorney and explore your options.
