Andy Murray will continue to work with coach Amelie Mauresmo in 2016, but Jonas Bjorkman will no longer be part of the Scot's team.
Mauresmo gave birth to her first child in August, but is planning to work 22 to 24 weeks with Murray next year.
World number two Murray, 28, will now begin the search for a new assistant coach following Swede Bjorkman's exit.
He will hope to have one in place for the first Masters event of the year in Indian Wells in March.
