Hi, thank you for your question. Just a bit more information required to fully assist you:
-Are you in England or Wales?
-What is she pursuing you for?
Thank you for the further information. If she is claiming that you are the father, despite you not being named on the birth certificate and her previously refusing maintenance, she would be entitled to make a claim to the Child Maintenance Service for maintenance and this is limited to a calculation based on your gross income and the amount of time the child spends with you overnight.
However, if you dispute being the father, then the CMS can be informed of this if she pursues a claim and they would require evidence from either of you to support parentage. If no evidence is readily available they will require a DNA test. you would then need to undertake a DNA/paternity test.
If there is a calculation in place for child maintenance, unfortunately you would need to pay the liability, however if it is later found that you are not the father then she will need to pay this back.
I hope this assists you. If you found this information helpful please provide a positive rating using the stars at the top of this page. I will not be credited for your question without a positive rating. Thank you.
