Cross-remainder

Where land is devised or conveyed to two or more persons as tenants in common, or where different parts of the same land are given to such p'ersons in severalty, with such limitations that, upon the determination of the particular estate of either, his share is to pass to the other, to the entire exclusion of the ultimate remainder-man or reversioner until ali the particular estates shall be exhausted, the remainders so limited are called "cross-remainders." In wills, such remainders may arise by implication; but, in deeds, only by express limitation.
