It's a national disgrace that a country which 'pretends' it does not allow divorce, punishes its citizens with the incredible cost to obtain a euphemistically called annulment, which is of course nothing of the sort. If it were then those who obtained it could get married in the church which of course they cannot. They should just pass legislation to overtly permit, divorced, which they do, with a simple, straightforward system which could be negotiated by individuals, without the need for legal representation and at a cost which reflected such a system.
Added later:-
So why does the present expensive and unfair, system exist and continue ?
In UK the largest group in Parliament are lawyers. If government passes any law which simplifies the way things are done it means that lawyers in general will earn (be able to charge) less. Thus in UK the quality of new laws appears to ensure that lawyer will not lose out. (An example which I knew very well was the 1968 Theft Act which was so full of holes, which meant for years, lawyers, on high fees, were fighting cases in court to establish the meaning of the law. That law could have been almost watertight if Parliament had had the citizens needs foremost in their minds).
I suspect that things in RP are not that much different from UK and that the legislators protect the money making practices, which ensure lawyers get paid excessive fees, are protected by legislation, whist the ordinary citizen gets screwed and his/her need are in the main ignored.
