Ok, what I say here under is as far as I know -- hindi ako nag pa annul but 2 brothers have, 3 friends have, and 1 employee...
It is now very hard to get an annulment coz dati na abuse. Kaya we need a Divorce Law, really.
Usual reason: psychological incapacity of 1 or both spouses. Usually, kung sino mas hot magpa annul says: sige, ako yung kalokerz.
Minimum cost: 450thou. Ang mahal? To some, it is cheaper than a funeral/dying - so, puede na rin.
Yes, with or without an annulment, a father SHOULD give his biological child support que with or without another partner/FUBU/BF/whatever his ex wife/partner/lavandera or 1-fck-standng-room-only pokpok biological mom has living with her now.
Please get it into your brother's cocote that responsible adults take care of their offspring/s even if the relationship that spawned such went kaput.
Please do not kunsinti him to be madamot -- hindi kasalanan ng bata the failure of its parents'relationship. Plus, the kid has basic rights (may batas to cover that, paki research: right to shelter, , food, education, etc etc etc)
So anong good reason to not give child support? He is incapable of working & has no inheritance/trust fund to draw funds from; he is in prison for years....
The Church has its own tribunal or legal court. If your bro gets his marriage annulled there - he can get married in church again. The people I mentioned I know with annulled marriages. -- not all remarried. Those who did, did it civilly & had no/a Christian/Buddhist marriage ceremony. (Hindi na carry ng pagka tsismosa ko to inquire about their cases pending with the tribunal, if they did file. Sorry)
Ano kaya magiging obligation ng brother ko pag naannul na sila?
CHILD SUPPORT is one -- unless his ex-wife says no need, in court.
Plus whatever else the court will decide is his obligation.
Such as, Kasi usually hati sa properties -- so obligated your bother to liquidate/turnover
