I Live In New York State. I Have A Son That Has My Last Name. My Son's Father Is On The Birth Certificate And Has Signed Acknowledgement Of Paternity. I Was Wondering Since He Signed That Can He Change My Son's Last Name. We Have Been To Child Support And He Pays 50 Dollars A Month And Has Brought Up The Name Change In Front Of The Judge The Judge Just Told Him He Had To Talk To Me About That. So I Was Wondering Could He Still Petition The Court To Change It. My Son Is 10 Months Old
