Maryland Code, Courts and Judicial Proceedings § 10-802

Where two or more beneficiaries are designated to take successively because of survivorship under another person's disposition of property and there is not sufficient evidence that these beneficiaries have died other than simultaneously, the property disposed of shall be divided into as many equal portions as there are successive beneficiaries, and these portions shall be distributed to those who would have taken in the event that each designated beneficiary had survived.
