(1) If the court finds that the will was properly executed, that the testator had the requisite testamentary capacity and freedom from undue influence at the time of execution, and that the will is otherwise valid, it shall declare the will valid and order it placed on file with the court.
(2) A finding of validity pursuant to this subchapter shall constitute an adjudication of probate. However, such validated wills may be modified or superseded by subsequently executed valid wills, codicils, and other testamentary instruments, whether or not validated pursuant to this subchapter.
