The appellant former husband appeals from an order of the trial court entered on his petition for modification of his alimony and child-support obligations under a divorce and alimony decree that had incorporated an alimony and child-support contract between him and his former wife appellee herein.

2. A decrease of alimony and child-support payments may be warranted, but is not demanded by, a substantial increase in the former wife's income or financial status since the date of the divorce decree ( McBrayer v. McBrayer, 227 Ga. 224 (2) (179 SE2d 772) (1971)) or a substantial decrease in the former husband's income or financial status in such period. Culberson v. Culberson, 237 Ga. 269 (227 SE2d 265) (1976). From the record before us, we can not determine that the trial judge failed to consider evidence of the former wife's increased financial status and the former husband's decreased income, in his order modifying the monthly payments from $600 to $300 for alimony and from $500 to $300 for child support.
