Pennsylvania has no-fault and fault divorces. No-fault requires irretrievable breakdown of the marriage and either a mutual consent to the entry of the divorce decree or a two year separation. There are a number of fault grounds, including grounds or charges of adultery, indignities, desertion and other marital wrongs.
Most contested divorces arise from property division disputes.
It is possible to separate while living in the same household. However, the proof of such a separation is difficult. A party must have lived in Pennsylvania for at least six months before having a right to sue for divorce. There may be cases where some parties have no right to sue in any state for divorce until residency is acquired. A mutual consent no-fault divorce takes about four to five months right now.
