There are two ways. *IF* the sons are the only inheritors under the law, you can DISCLAIM the money. It will then pass to them.
Or, if that is not clear by the law, will, trusts or whatever, you can take the money and GIFT it to them. If the amount is above $12,000, you would need to file a gift tax return. However, unless you have given or plan to give over $1 million in your lifetime, no taxes would be due. (At this time. Obama seems to want to target this "loophole".)
When you are a Bear of Very Little Brain, and you Think of Things, you find sometimes that a Thing which seemed very Thingish inside you is quite different when it gets out into the open and has other people looking at it.
