20 CFR § 725.233 - Support and contributions.
(a)Supportdefined. The term “support” includes food, shelter, clothing, ordinary medical expenses, and other ordinary and customary items for the maintenance of the person supported.
(b)Contributionsdefined. The term “contributions” refers to contributions actually provided by the contributor from such individual's property, or the use thereof, or by the use of such individual's own credit.
(c)Regular contributions and substantial contributionsdefined. The terms “regular contributions” and “substantial contributions” mean contributions that are customary and sufficient to constitute a material factor in the cost of the individual's support.
(d)Contributions and community property. When a spouse receives and uses for his or her support income from services or property, and such income, under applicable State law, is the community property of the wife and her husband, no part of such income is a “contribution” by one spouse to the other's support regardless of the legal interest of the donor. However, when a spouse receives and uses for support, income from the services and the property of the other spouse and, under applicable State law, such income is community property, all of such income is considered to be a contribution by the donor to the spouse's support.
(e)Court order for supportdefined. References to a support order in this subpart means any court order, judgment, or decree of a court of competent jurisdiction which requires regular contributions that are a material factor in the cost of the individual's support and which is in effect at the applicable time. If such contributions are required by a court order, this condition is met whether or not the contributions were actually made.
(f)Written agreementdefined. The term “written agreement” in the phrase “substantial contributions pursuant to a written agreement”, as used in this subpart means an agreement signed by the miner providing for substantial contributions by the miner for the individual's support. It must be in effect at the applicable time but it need not be legally enforceable.
(g)One-half supportdefined. The term “one-half support” means that the miner made regular contributions, in cash or in kind, to the support of a divorced spouse at the specified time or for the specified period, and that the amount of such contributions equalled or exceeded one-half the total cost of such individual's support at such time or during such period.
(h)Totally dependent for supportdefined. The term “totally dependent for support” as used in § 725.225(b) means that the miner made regular contributions to the support of the miner's parents, brother, or sister, as the case may be, and that the amount of such contributions at least equalled the total cost of such individual's support.
