(d) For the purposes of this section, a court may consider the following factors:

1. (1) whether another state is or recently was the child's home state;
2. (2) whether another state has a closer connection with the child and his family or with the child and one or more of the contestants;
3. (3) whether more substantial evidence concerning the child's present or future care, protection, training, and personal relationships is available or whether such evidence is more readily available in another state;
4. (4) whether the parties have agreed on another forum which is not less appropriate; and
5. (5) whether the exercise of jurisdiction by a court of the commonwealth would contravene any of the purposes of this chapter.

(e) If a court shall find that a court of another jurisdiction is or may be a more appropriate forum under the terms of this chapter for the adjudication of the custody proceeding, it may do one or more of the following:

1. (1) dismiss the proceeding with or without prejudice;
2. (2) vacate any order or judgment already entered;
3. (3) stay the proceeding upon condition that a custody proceeding be initiated or prosecuted in another state in a timely manner or upon any other condition that the court might deem just;
4. (4) retain jurisdiction over any action to which the custody proceeding is incident, while declining to render a custody determination;
5. (5) enter such temporary order or orders as may be required, in the court's discretion, pursuant to clause (ii) of paragraph (3) of section two;
6. (6) assess any or all of the costs of the custody proceeding in this state, having due regard for the purposes of this chapter, including the reasonable travel and other expenses of any party and his or her witnesses, the reasonable attorneys' fees of any party, the costs of the court's communications and information exchanges with other courts and the fees and costs of any person entitled to appear before the court as the representative of a child;
7. (7) assess sanctions against any party whom the court finds has engaged in illegal or otherwise wrongful conduct;
8. (8) enter any other order or judgment which may be meet and just under the circumstances of the case.
