Section § 733
This law explains what happens to income from a property when there is a delay in transferring ownership. If no instructions are given about how to handle this income during that delay, it automatically goes to the people who are expected to inherit the property next.
When, in consequence of a valid limitation of a future interest, there is a suspension of the power of alienation or of the ownership during the continuation of which the income is undisposed of, and no valid direction for its accumulation is given, such income belongs to the persons presumptively entitled to the next eventual interest.
