26 U.S. Code § 2043 - Transfers for insufficient consideration
If any one of the transfers, trusts, interests, rights, or powers enumerated and described in sections 2035 to 2038, inclusive, and section 2041 is made, created, exercised, or relinquished for a consideration in money or money’s worth, but is not a bona fide sale for an adequate and full consideration in money or money’s worth, there shall be included in the gross estate only the excess of the fair market value at the time of death of the property otherwise to be included on account of such transaction, over the value of the consideration received therefor by the decedent.
For purposes of this chapter, a relinquishment or promised relinquishment of dower or curtesy, or of a statutory estate created in lieu of dower or curtesy, or of other marital rights in the decedent’s property or estate, shall not be considered to any extent a consideration “in money or money’s worth”.
For purposes of section 2053 (relating to expenses, indebtedness, and taxes), a transfer of property which satisfies the requirements of paragraph (1) of section 2516 (relating to certain property settlements) shall be considered to be made for an adequate and full consideration in money or money’s worth.
1984—Subsec. (b). Pub. L. 98–369 amended subsec. (b) generally, designating existing provisions as par. (1) and adding par. (2).
Written determinations for this section
These documents, sometimes referred to as "Private Letter Rulings", are taken from the IRS Written Determinations page; the IRS also publishes a fuller explanation of what they are and what they mean. The collection is updated (at our end) daily. It appears that the IRS updates their listing every Friday.
Note that the IRS often titles documents in a very plain-vanilla, duplicative way. Do not assume that identically-titled documents are the same, or that a later document supersedes another with the same title. That is unlikely to be the case.
Release dates appear exactly as we get them from the IRS. Some are clearly wrong, but we have made no attempt to correct them, as we have no way guess correctly in all cases, and do not wish to add to the confusion.
We truncate results at 20000 items. After that, you're on your own.
