The New York Personal Information Form for IFSA 311 is a document used in the Uniform Interstate Family Support Act (IFSA) process. It is used to collect information about the parties involved in a child support case, such as names, addresses, dates of birth, Social Security numbers, and contact information. It is also used to establish the noncustodial parent's legal obligation to pay child support. The form is typically used by the court, the support enforcement agency, or the custodial parent to collect information for the purposes of establishing, modifying, or enforcing a support order. There are two types of New York Personal Information Form for IFSA 311: the original form and the updated version. The original form is used when the child support case is first established. The updated version is used when the custodial parent needs to update their information or when the noncustodial parent needs to update their information.
