Modifying alimony

Changed circumstances such as a change in income or your financial situation are grounds for a modification of alimony and/or child support.
You will need to file with the court an Order to Show Cause to request a hearing on the modification of alimony and child support.  Call the court clerk to schedule a hearing and include the hearing date/time/department in your Order to Show Cause.  Also file a declaration signed under penalty of perjury stating the facts in support of your request for a modification of alimony and child support.  Include any other documents, items, etc. that provide evidence supporting your argument for a modification of alimony and child support.  File all of these documents and a proof of service with the court. Then, mail a copy of your court-filed documents with the proof of service to your ex to provide your ex with notice of the hearing.  The proof of service (court form) verifies the date of mailing your documents to your ex.
Prior to filing the above documents with the court, ask the court clerk if there are any other required documents you need to file for a modification of alimony and child support because the required documents may vary from state to state.
