My dear The gr8 man do you ever think that mere signing on MOU before first motion and get that notarized you have got divorce decree?
You have done blunder mistake by handing cheque before second motion and even in the absence of court.
There is no rule right now which say's that once MOU signed you got decree, for geting final decree you both have to be present for first motion and give your facts about so and so cause you both are permanently seperating. Then again after 6 months you both have to reperesent the same megisterate and accord your ascent on speration,then after one or two weeks you will get decree.
In this crucial time frame,even after first motion if she want's then she will walk out...!!
There is no law for it right now,that's what a new marriage amendment bill 2013 is on the rock...
The Mou which is made should be mentioned by each and every doubt's which you have in your mind and it is alway's prefferable to sign infront of the judge and the alimony has to be passed once you both come for second motion infront of the judge.
Now,recall yourself and see what can be done , consult your lawyer,just research this LCI how to safeguard you MOU and final alimony in MCD.
Best of luck.
