My friend is imigrant and planing to devorce her husband in the philippines,is it posible to do that?and how much it will be just in case?

Your question is a bit unclear; presumably, you mean your friend intends to file for divorce in the U.S., not in the Philippines.  The short answer is "yes," but there are a lot of questions about what can and can't be done, depending on facts you do not state:  Are there kids?  Where?  Will the spouse cooperate, fight, or ignore the action?  Is there any property?  Where? How long is the marriage?  Is anyone seeking alimony? It is impossible to provide much more information from a question this general, but you may find the answers you are looking for at these locations: http://www.willicklawgroup.com/divorce/ http://www.willicklawgroup.com/grounds-and-jurisdiction/ http://www.willicklawgroup.com/spousal-support-alimony/ http://www.willicklawgroup.com/property-rights-and-division/ http://www.willicklawgroup.com/child-custody-and-visitation/
