Narrative:

A BE40 was a bct departure. Our LOA states that pbi [TRACON] will climb the aircraft into our airspace to 10;000 once a hand-off is accepted. Mia approach gave a late hand-off on a LJ31 which was an fxe departure; which is the reason for the late hand-off. When I realized the potential situation; I called miami approach and requested the LJ31 be stopped at 11;000 thinking I would be able to top the BE40. When I realized this would not be possible; I stopped the BE40 at 10;000 and I finally I received communications with the LJ31 on the boundary and immediately turned him left to a heading of 290 and climbed the aircraft. Lateral separation was lost as the LJ31 climbed through 10;800. I think it would be better to climb the bct departure to 7;000 and give the sector control for climb in case there is a late hand-off like in this situation.

Title: ZMA Controller experienced a loss of separation event when departure traffic from both PBI and MIA TRACON's conflicted with no time to issue separation vectors. The reporter suggested alternate procedures.

Narrative: A BE40 was a BCT departure. Our LOA states that PBI [TRACON] will climb the aircraft into our airspace to 10;000 once a hand-off is accepted. MIA Approach gave a late hand-off on a LJ31 which was an FXE departure; which is the reason for the late hand-off. When I realized the potential situation; I called Miami Approach and requested the LJ31 be stopped at 11;000 thinking I would be able to top the BE40. When I realized this would not be possible; I stopped the BE40 at 10;000 and I finally I received communications with the LJ31 on the boundary and immediately turned him left to a heading of 290 and climbed the aircraft.
