If you choose to leave your spouse and children, if any, that does not constitute abandonment. Also, leaving the marital home, does not necessarily mean that you will lose title to the it or any equity in it.  If a divorce complaint is filed which includes a count for equitable distribution, then you and your spouse will have to divide your marital property. Under PA law, a husband and wife do not automatically receive 50% of the marital property.  Instead, an equitable distribution is based upon a variety of statutory factors. Thus, the marital property may be divided 60/40 or 55/45 or even 75/25, depending upon the facts of your particular situation.
