Any parent or person who has legal custody of a child can get help in locating the child's other (non custodial) parent, establishing a child's paternity. These are the official forms for use in Family Court proceedings.Below, our Suffolk County child support lawyer outlines the most frequently asked questions we hear about the subject, and the answers to them. You will also receive a financial disclosure form to fill out and be directed to bring certain documents with you when you come to court. You can only state what you know or estimate. The other party is required to provide a full financial disclosure as part of the case.
