Kim Zolciak and Kroy Biermann might not be having as many public explosions as last year … but the divorce is still going on, with sources telling us the fighting never stops.

Sources with direct knowledge tell TMZ … Kim & Kroy are still on the divorce track, even though there hasn’t been much in the news about the soon-to-be exes.

We’re told the two are at each other a lot, with their on-and-off fighting persisting … but, police haven’t had to respond for a while, so it seems to be somewhat civil in the house.

We’re told Kim & Kroy have good days and bad … but, they have a tendency to get into verbal arguments about even very little things — partially caused, according to our sources, because they’re divorcing yet still living in the same house.

The couple’s money issues have been well-documented of course … with the IRS and a series of other debt collectors demanding money they say the couple owes.

To make matters worse, Kim and Kroy can’t seem to sell their house … a potential influx of cash that could alleviate some of their money woes. They’ve dropped the price twice already, coming all the way down from the original $6M listing to $4.5M.

This divorce saga has been going on for a while now … with Kim and Kroy racing to the courthouse to file back in May of last year. They called off the divorce a couple months later before Kroy filed again in September.

The biggest moment came in November … when a huge blow-up between the two led one of their children to call the cops. No one was arrested, but the video seemed to show a house in crisis.
