'Bachelor in Paradise' Star Amanda Stanton's Child Support Takes a Hit

Amanda Stanton's monthly checks from her ex just got slashed by almost 75% ... but at least her fiance's still by her side.

Amanda and her fiance, Josh Murray, were together in family court when Amanda lost a battle in her ongoing custody and child support war with her ex-husband, Nick Buonfiglio.

Nick wanted to pay less child support to the "Bachelor in Paradise" star for their 2 daughters, and the judge agreed -- cutting his payments from $2k a month down to $530.

The reasoning is simple -- Amanda admits she's making more cash after being on 'BiP' ... while Nick says he's had financial hardships.
