There are two ways to look at your subsequent query;
First - Get over with MCD second motion by amending MoU adding a line that "in case wife (mother) changes her residence address and or cell phone no., she will inform to husband (natural father) within 24 hrs. by SMS / Email of natural father and receive decree in divorce accordingly.
Second - Ask him to take Hanuman's leap overnight and first find a better Lawyer + file Contempt of Court via second advocate. [But what was he doing all these 4 months is a natural question if I may ask (you are not required to reply to this as I can see you are some third party piggy querying us)]
However, in either options process flow I would prefer first option for few simple emerging facts, that are; natural father is currently in overseas country + returning to Indian soils sometime in July + almost had not much of a support from his current advocate + we are not sure what is his first priority -MCD decree aor visitation (visitation can always change as per circumstances) + why no mention of communication address / cellphone of parties exchange in 24 hrs. in case of change as a para not mentioned to safeguard child best interest + we do not know who you are who is asking these queries on behalf of a natural father which makes such strong resolve for contest or bringing such willful lapses of a co-petitioner (wife - mother) on record meaningless (means less result oriented) as so called third party presentation of a case somehow looses much of its sheen in days to come and cumulatively all these emerging facts are not encouraging signs to bring to table (or that matter to a concerned Court view) either a HCP and or a Contempt petition and or even possible for him to be present during pleadings in the best interest of a child is my view.
Also note an Advocate is not just stumbled upon via internet search by a third party infact all one-on-one due diligence are required before hiring services of an advocate (this is my view and it is not that I’m against any of my fellow ld. brothers presence in internet forums).
