(h) For the purposes of this chapter, earnings shall include, but not be limited to, spousal, family, and child support payments, pensions, social security, disability or survivorship benefits.
Spousal, family, and child support payments shall be considered in the same manner as earnings from salary, wages, or other sources where the payments are received pursuant to a written agreement or court decree to the extent that the reliability of such payments is established. The factors which a creditor may consider in evaluating the reliability of such payments are the length of time payments have been received; the regularity of receipt; and whether full or partial payments have been made.
