Section 211 - Arrears/past due support1. The New York state office of temporary and disability assistance, or a local social services district, or its authorized representative on behalf of persons receiving services under title six-A of article three of the social services law shall have a lien against personal property owned by a support obligor when such support obligor is or was under a court order to pay child support or combined child and spousal support to a support collection unit and such support obligor has accumulated support arrears/past due support in an amount equal to or greater than the amount of support due pursuant to such order for a period of four months. Such lien shall be in an amount sufficient to satisfy such support arrears/past due support. Said lien shall be perfected in the case of a vehicle as that term is defined in section two thousand one hundred one of the vehicle and traffic law with the department of motor vehicles. The filing of a notice of lien or of a release of lien shall be completed without payment of a fee. The filing of notice of lien or release of lien may be done by electronic means.2. The state shall accord full faith and credit to liens which arise in another state when such state agency, party or other entity seeking to enforce such a lien complies with the procedural rules relating to such liens as provided for in section one hundred eleven-u of the social services law, article forty-six of the vehicle and traffic law or article nine of this chapter as is appropriate. Such rules may not require judicial notice or hearing prior to enforcement of such a lien and enforcement shall be governed by article nine of this chapter.3. For the purposes of determining whether a support obligor has accumulated support arrears/past due support for a period of four months, the amount of any retroactive support, other than periodic payments of retroactive support which are past due, shall not be included in the calculation of arrears/past due support pursuant to this section; however, if at least four months of support arrears/past due support have accumulated subsequent to the date of the court order, the entire amount of any retroactive support may be collected pursuant to the provision of this section or as otherwise authorized by law.
