SECTION 1. Section 5-305 of chapter 190B of the General Laws, as appearing in the 2010 Official Edition, is hereby amended by striking out subsections (c) and (d) and inserting in place thereof the following subsection:-

(c) Except as provided in subsection (b), the following, if suitable, are entitled to the presumption that they are the proper person for appointment as guardian of an incapacitated person by the court in the order listed; provided, however, that such presumption may be rebutted by the introduction of competent evidence:

(1) the spouse of the incapacitated person or a person nominated by will of a deceased spouse or by other writing signed by the spouse and attested to by at least 2 witnesses;

(2) the parent or parents of the incapacitated person, or a person nominated pursuant to section 5-301; and

(3) any person the court deems appropriate.

A spouse, parent or parents wishing to designate a third party to serve as guardian of such person may freely elect to do so without prejudice. In such instances, the party so designated shall be presumed to the proper person to be appointed by the court.  Such presumption may be rebutted by the introduction of competent evidence.
