Assuming you both are current residents of Pennsylvania, and you are filing for divorce, there are many types of spousal support. Two commonly known are Alimony (full blown spousal support with stipulated restrictions such as duration of support and qualifying terms such as remarriage etc.) and Alimony Pendente Lite (popular form of spousal support with very little restrictions except that once the divorce is final, the support usually ceases). All forms of spousal support in Pennsylvania are calculated with a formula based upon both incomes of the parties, the length of the marriage, the standard of living during the marriage and the contribution toward the marital home).
Regarding the debts issue: The parties are generally each solely responsible for any debt incurred in his/her own name during the marriage. Any joint debt obligations would make each party equally responsible (Remember a property settlement or divorce agreement does not excuse you from a joint debt obligation no matter who is specified to assume responsibility for what! A settlement agreement is between the divorcing parties only, and creditors are not bound to such agreement whatsoever.
Good luck to you.
