Maryland Health Occupations Section 7-410
§ 7-410.
  (a)   Any individual who is 18 years of age or older may decide the disposition of the individual's own body after the individual's death without the pre-death or post-death consent of another person by executing a document that expresses the individual's wishes or by entering into a pre-need contract.
  (b)   In order to be valid, any document executed under subsection (a) of this section must be written and signed by the individual in the presence of a witness, who, in turn, shall sign the document in the presence of the individual.
  (c)   Unless a person has knowledge that contrary directions have been given by the decedent, if a decedent has not executed a document under subsection (a) of this section, the following persons, in the order of priority stated, have the right to arrange for the final disposition of the body of the decedent under this section and are liable for the reasonable costs of preparation, care, and disposition of the decedent:
    (1)   The surviving spouse of the decedent;
    (2)   An adult child of the decedent;
    (3)   A parent of the decedent;
    (4)   An adult brother or sister of the decedent;
    (5)   A person acting as a representative of the decedent under a signed authorization of the decedent;
    (6)   The guardian of the person of the decedent at the time of the decedent's death, if a guardian has been appointed; or
    (7)   In the absence of any person under paragraphs (1) through (6) of this subsection, any other person willing to assume the responsibility to act as the authorizing agent for purposes of arranging the final disposition of the decedent's body, including the personal representative of the decedent's estate, after attesting in writing that a good faith effort has been made to no avail to contact the persons described in paragraphs (1) through (6) of this subsection.
  (d)   (1)   Subject to paragraph (2) of this subsection, if a decedent has more than one survivor under subsection (c)(1) through (4) of this section, any adult child, parent, or adult brother or sister of the decedent who confirms in writing to a licensee that all of the other members of the same class have been notified may serve as the authorizing agent unless the licensee receives a written objection from another member of that class.
    (2)   If a decedent has more than one survivor under subsection (c)(1) through (4) of this section, the majority of a class may serve as the authorizing agent.
  (e)   For an individual whose final disposition is the responsibility of the State or any of its instrumentalities, a public administrator, medical examiner, coroner, State-appointed guardian, or any other public official charged with arranging the final disposition of the body of the individual may serve as the authorizing agent for purposes of this section.
  (f)   For an individual who has donated the individual's body to medical science or whose death occurred in a nursing home or other private institution, a representative of the institution to which the body was donated or in which the decedent died may serve as the authorizing agent of the decedent and the institution is charged with making arrangements for the final disposition of the body.
