Actors Tisha Campbell and Duane Martin's divorce turns nasty after she accuses him of being difficult where their children are concerned...
From TMZ
In the docs, obtained by TMZ, she says Duane will often not respond to her nor cooperate on previously agreed upon swap times for the kids -- adding that he also threatens to keep their sons beyond his allotted dad time.
Tisha is asking a judge to put a 50-50 custody deal in writing with an alternating weekly schedule and a neutral exchange location ... like a police station, she suggests.
She also wants a judge to force Duane to respond to her emails within 24 hours.
