I still do not know what your point is, since what you just posted as links state just what I was summarizing for you.
I stated above about SSDI benefit, just what this says:
SSD benefits are attachable for child support purposes, because section 207 of the Act is expressly overridden by section 459(a) of the Act (42 U.S.C. 659(a)). Section 459 provides that payments from the Federal government, the entitlement to which is based upon remuneration for employment, are subject to income withholding or other legal process brought by a State IV-D agency or an individual obligee for purposes of enforcing child support obligations. Section 459(h)(1)(A)(ii)(I) of the Act (42 U.S.C. 659(h)(1)(A)(ii)(I)) specifies that payments under Title II of the Act, which includes SSD payments, are considered to be based upon remuneration for employment. In addition, federal regulations governing federal personnel at 5 C.F.R. 581.103(c)(1) specify that SSD is attachable for child support purposes.
SSD funds can be attached to satisfy child support obligations even if the support entitlement has been assigned to the State. The assignment does not change the nature of the debt, only the payee. See, Knickerbocker v. Norman, 938 F.2d 891 (8th Cir., Iowa,1991), Shepherd v. Shepherd, 467 N.W.2d 237 (Iowa 1991).
Furthermore, Some courts have held that, although SSI payments can not be attached through legal process for the enforcement of child support obligations, they can be considered income for purposes of calculating the child support obligation. See, Davis v. Office of Child Support Enforcement, 5 S.W.3d 58 (Ark. App. 1999), Commonwealth ex rel. Morris v. Morris, 984 S.W.2d 840 (Ky. 1998), reh. denied 2/18/99, Whitmore v. Kenney, 626 A.2d 1190 (Pa. Super. 1993).)
