Narrative:

I was taking east departure at C90 to train my developmental. After I was briefed, I gave A320 a 20 degree heading and climbed to 13000 ft. A320 was at 6000 ft in another controller's airspace, for which he received a pointout. At approximately XA15Z, I heard the other controller question the climb, and noticed his aircraft was climbing into my A320. I issued traffic. He saw the traffic. I issued a visual separation clearance and reiterated the climb once I heard the other aircraft was descended. The other controller said after that, he was going to top A320, but did not say prior. No coordination was provided prior, except for approving the pointout of the A320. Arrival owns 7000 ft and above. I was at departure's highest altitude and was using departure's pre-arranged coordination with arrival airspace as per our C90 order. I believe I issued the visual separation clearance prior to losing separation. I reiterated this to my supervisor when asked. A320 did have the other aircraft in sight and questioned if he was to stay at 7000 ft or continue to climb. I told him 'climb and maintain 13000 ft.'

Original NASA ASRS Text

Title: C90 DEP AND ARR CTLRS DID NOT COMMUNICATE INTENTIONS WITH 2 CLBING ACFT.

Narrative: I WAS TAKING E DEP AT C90 TO TRAIN MY DEVELOPMENTAL. AFTER I WAS BRIEFED, I GAVE A320 A 20 DEG HDG AND CLBED TO 13000 FT. A320 WAS AT 6000 FT IN ANOTHER CTLR'S AIRSPACE, FOR WHICH HE RECEIVED A POINTOUT. AT APPROX XA15Z, I HEARD THE OTHER CTLR QUESTION THE CLB, AND NOTICED HIS ACFT WAS CLBING INTO MY A320. I ISSUED TFC. HE SAW THE TFC. I ISSUED A VISUAL SEPARATION CLRNC AND REITERATED THE CLB ONCE I HEARD THE OTHER ACFT WAS DSNDED. THE OTHER CTLR SAID AFTER THAT, HE WAS GOING TO TOP A320, BUT DID NOT SAY PRIOR. NO COORD WAS PROVIDED PRIOR, EXCEPT FOR APPROVING THE POINTOUT OF THE A320. ARR OWNS 7000 FT AND ABOVE. I WAS AT DEP'S HIGHEST ALT AND WAS USING DEP'S PRE-ARRANGED COORD WITH ARR AIRSPACE AS PER OUR C90 ORDER. I BELIEVE I ISSUED THE VISUAL SEPARATION CLRNC PRIOR TO LOSING SEPARATION. I REITERATED THIS TO MY SUPVR WHEN ASKED. A320 DID HAVE THE OTHER ACFT IN SIGHT AND QUESTIONED IF HE WAS TO STAY AT 7000 FT OR CONTINUE TO CLB. I TOLD HIM 'CLB AND MAINTAIN 13000 FT.'
