Conn. Gen. Stat. § 45a-505
A fee simple determinable in land or a fee simple in land subject to a right of entry for condition broken shall become a fee simple absolute if the specified contingency does not occur within thirty years from the date when such fee simple determinable or such fee simple subject to a right of entry becomes possessory. If such contingency occurs within such thirty years, the succeeding interest, which may be an interest in a person other than the person creating the interest or his heirs, shall become possessory or the right of entry exercisable notwithstanding the rule against perpetuities. If a fee simple determinable in land or a fee simple in land subject to a right of entry for condition broken is so limited that the specified contingency must occur, if at all, within the period of the rule against perpetuities, said interests shall take effect as limited. This section shall not apply where both such fee simple determinable and such succeeding interest, or both such fee simple and such right of entry, are for public, charitable or religious purposes; nor shall it apply to a deed, gift or grant of the state or any political subdivision thereof.
