In Alabama, a fundamental change in circumstances is required to modify alimony. Rarely is alimony adjusted upward based upon the payer's increased income. More often, alimony is decreased based on the payer's decrease in income due to circumstances beyond their control.
The case of Ex parte Ederer, 900 So. 2d 424 (2004) says:
An obligation to pay alimony may be modified only upon a showing of a material change in circumstances that has occurred since the trial court's previous judgment, and the burden is on the party seeking a modification to make this showing. Thus, the moving party must show a material change in the financial needs of the payee spouse and in the financial ability of the payor spouse to respond to those needs. A trial court is not, however, required to modify alimony because of a change in the circumstances of the parties.
The only thing you can do is file a motion with the court to increase alimony based on your reduction in income and your disability.
If you can't afford an attorney to handle this, you should contact your county circuit court clerk's office to see if there are any forms available. If not, you should contact the Alabama Bar Assn. (www.alabar.org) about finding an attorney in the area to assist you.
