Does they length of marriage matter for alimony in Pennsylvania?

In Pennsylvania, the courts consider the length of the marriage, the earnings of each spouse, and the marital misconduct of either party during the marriage, and other factors, in deciding whether one party should pay alimony to the other and for how long it should be paid.  Alimony can be ordered for a definite period of time (until a specific end date) or an indefinite period of time (without a specific end date), whichever the court finds to be reasonable under  the circumstances of the case.  Generally, short term marriages result in short term alimony unless unusual circumstances exist.
