531. Merger of term at law and in equity.

At common law, where a term of years becomes vested in the owner for the time being of the reversion immediately expectant on the term, the term is merged in the reversion1. Thus, a person cannot at law be reversioner to himself2. For this purpose, the reversion is deemed to be the greater estate, notwithstanding that it is in fact shorter than the term; hence a term of 1,000 years can be merged in a reversionary term of 500 years3. Even at common law there was no merger if the interests were held by one person in different rights
